t has been said that mandatory punishments are as
old as civilization itself. The biblical lex talionis– an
eye for an eye, a tooth for a tooth – was mandatory,
leaving little room for clemency or mitigation of
punishment. Mandatory penalties were also enshrined
in early Anglo-Saxon law, prescribing set fines for every
conceivable form of harm (Wallace, 1993). In the United
States, mandatory minimum sentences (MMS) date back
to 1790 and, since the 1950s, have evoked considerable
ambivalence. In American federal law today, over 60
statutes contain MMS, although only four, covering drug
and weapons offences, are used with any frequency
(Wallace, 1993).
By 1999, The Criminal Code of Canadacontained 29
offences carrying MMS (Appendix A). Nineteen of these
offences were created in 1995 with the enactment of Bill
C-68, a package of firearms legislation. MMS appear to
be increasing in popularity with Members of Parliament,
as shown by the number of private members’ bills
introduced in the 1999 session (Appendix B). This review
was prompted by the increasing interest in MMS, as well
as by the controversy surrounding them. The principal
aim was to assess the effects of MMS through a review of
relevant social science and legal literature.
Several arguments have been advanced in favour of
MMS. Proponents believe that these penalties act as a
general or specific deterrent; that is, they dissuade
potential offenders from offending or actual offenders
from re-offending. They also claim that MMS prevent
crime by incapacitating or removing the offender from
society. Furthermore, MMS may serve a denunciatory or
educational purpose, by communicating society’s
condemnation of given acts. Moreover, MMS are
thought to reduce sentencing disparity.
Opponents assert that MMS have little or no deterrent or
denunciatory effect. They also maintain that the rigid
penalty structure limits judicial discretion, thereby
preventing the imposition of just sentences.
Furthermore, there is the concern that the rigidity of
MMS may result in some grossly disproportionate
sentences. In addition, opponents assert that MMS can
make it difficult to convict defendants in cases where the
penalty is perceived as unduly harsh. Moreover, there is
a concern about the fiscal consequences of these
penalties, as they may increase the burden on
prosecutorial resources and produce substantial
increases in prison populations. Finally, MMS may
exacerbate racial/ethnic biases in the justice system if
they are applied disproportionately to minority groups.
The primary aim of this review was to assess the
utilitarian aspects of MMS; that is, the crime preventive,
fiscal, and social consequences of MMS, as well as
impediments to their implementation. This review did
not consider constitutional/Charter issues raised by
these penalties.

his review covered the period from 1980 to 2000
inclusive, although several earlier studies were
included due to their salience. The databases
searched included Current Contents, Soc Abstracts,
PsycINFO, and Legal Trac. Dozens of key words were
used in the searches including various combinations of
the following: mandatory sentences, mandatory
minimum penalties, deterrence, incapacitation,
denunciation, homicide, murder, impaired driving,
drugs, firearms, crimes, offences, disparity, capital
punishment.
Materials cited in this report included empirical studies,
as well as commentaries by jurists and prosecutors with
extensive first-hand experience with cases eligible for or
resulting in the imposition of a MMS.
2.0 Scope of the Review
Research and Statistics Division 3
A
principal aim of this review was to assess the
utilitarian aspects of MMS; that is, the potential
crime preventive benefits of such penalties. As
indicated in Section 1.0, these benefits can arise through
incapacitation, general or specific deterrence,
denunciation, or education (i.e., raising awareness and
sensitization). Since penalties already tend to exist in
areas where MMS are introduced (e.g., murder,
firearms-related crimes, impaired driving),
demonstrating that a given MMS has an absolute
deterrent or incapacitation effect is insufficient.
Sentences for robbery, for example, had a potential
preventive effect prior to the introduction of sentence
enhancements (MMS in addition to the primary offence)
for using a firearm in robberies and other offences.
Thus, the marginalor additional benefit of MMS over
previous penalties must be established (Shavell, 1992).
These marginal preventive effects, in turn, can exist only
if MMS actually increase the certainty and/or severity of
punishment. If their perceived severity results in fewer
guilty pleas and more cases proceeding to trial, the
certainty and celerity of their imposition may be
diminished relative to sentences imposed previously.
Also, MMS do not guarantee that sentence severity will
increase, as sentences under a previous sentencing
regime may have typically exceeded the minimum
penalty introduced. These concerns underscore the
necessity of examining the implementation of MMS, as
marginal benefits cannot accrue if MMS are
circumvented at the prosecutorial stage or fail to result
in more certain and severe punishment. This review,
therefore, devotes considerable attention to issues in the
implementation of MMS.
Even where the marginal preventive effects of MMS are
demonstrated, a further difficulty arises with regard to
the explanation of these effects. If a “three strikes” law,
such as that enacted in California, is accompanied by a
sharp decline in felonies over a period of several years,
to which utilitarian doctrine do we attribute this finding?
It is difficult to distinguish whether the law has proven
effective due to deterrence, incapacitation, moral
condemnation/sensitization, or some combination of
these factors. Few studies try to empirically determine
the relative importance of these explanations. As a
result, our focus here will be on the impact of MMS,
rather than on explaining any effects observed.
An additional issue is that MMS apply to a wide range of
sanctions internationally, from mandatory license
restrictions and fines for impaired driving to mandatory
life sentences and even the death penalty for certain
categories of murder. Thus, sweeping statements about
the utility of MMS are problematic. Sentences of varying
degrees of severity ought to be considered separately.
Accordingly, impaired driving, drug, and firearms
offences are discussed in different sections of this
report.
3.0 Some Theoretical and Conceptual
Issues
Research and Statistics Division 5
While MMS may serve political ends (placating public
indignation about one or more serious crimes) and
retributive goals, deterrence is presumably an important
aspect of such penalties. Incapacitation alone, whether
for retributive or utilitarian reasons, may ultimately
prove far too costly to sustain MMS. If there is no
deterrent effect, the correctional system is likely to face
a crisis due to the continual growth of the prison
population. Deterrence offers the hope that any short-
term increases in the prison population produced by
MMS will be offset by long-term reductions arising from
declining crime rates.
A number of recent developments and studies in the
field shed light on the potential deterrent effect of prison
sentences. Most of these studies relate to legal sanctions
and incarceration in general; they do not tend to
distinguish between mandatory and other types of
penalties.
4.1The Rational Choice Perspective
The deterministic view that social, biological, and
psychological forces shaped behaviour was dominant
throughout most of the 20th century. While some
criminality undoubtedly is an expression of pure rage
and often involves impaired judgment due to intoxicants
(Wolfgang, 1958; Innes, 1986), an important
development in criminological theorizing over the past
two decades has been the emergence of the rational
choiceperspective (Siegel and McCormick, 1999). While
not assuming complete rationality (Harding, 1990),
proponents regard offenders as active decision-makers,
rather than simply as passive actors responding to
adverse social conditions and psychological needs.
Offender decision-making encompasses a whole range
of choices, aside from the decision to commit a crime.
Offenders are seen as deciding on the timing and
location of their offences, choosing specific targets
(whether people or premises), and making decisions
about the means (e.g., weapons) they will use to commit
their offences. Documented patterns in different crimes
show that crimes are not merely committed in a random
fashion. Dozens of case studies, often involving
interviews with offenders, display their decision-making
processes and decision criteria (Clarke, 1997). Studies
also show that many offenders are anything but
indifferent to the risks, including imprisonment,
associated with their crimes (Brown, 1997; Gabor et al.,
1987). In this context, risk usually refers to the
likelihood of arrest and punishment, rather than its
severity. Furthermore, studies in this area show that
much crime is committed by a larger pool of individuals
responding to situational factors (e.g., opportunities,
risks, and transient motives) favourable to crime, rather
than simply a smaller group of hardcore offenders
(Gabor, 1994).
4.2Offender Characteristics
A series of studies appears to contradict the view of
offenders as rational and of crime as largely
opportunistic as they suggest that:
1) Among the strongest correlates of
criminality are antisocial attitudes and
associates, a history of antisocial
behaviour, and antisocial personality,
indicating that offenders are strongly
predisposed to committing their crimes
(Gendreau et al., 1992; Simourd and
Andrews, 1994);
2) Only a small proportion of incarcerated
offenders are “calculators”, carefully
weighing the costs and benefits of their
crimes (Benaquisto, 2000);
3) Many offenders would prefer to go to
prison than face community sanctions
and do not differentiate between a prison
sentence of three and five years (Spelman,
1995; Petersilia and Deschenes, 1994;
Crouch, 1993; Petersilia, 1990);
4) Incarceration does not appear to reduce
re-offending as offenders receiving
custodial sanctions have recidivism rates
similar to those receiving community
dispositions (Gendreau et al., 1999).
The apparent contradictions between the rational
choice perspective and the more pessimistic studies just
cited might be reconciled by the fact that the former
applies to a wider pool of offenders and potential
offenders, whereas the latter deal with re-offending
among a more intractable group of offenders, many of
whom have been previously incarcerated. Some
evidence does show that those who have been
previously punished are the most likely to recidivate
(Greenfield, 1985). Thus, criminal sanctions may
exercise a greater deterrent effect in relation to those
4.0 Can Offenders be Deterred?
Research and Statistics Division 7
with limited previous justice system contacts.
Incapacitation, on the other hand, may be more
effective than the threat of sanctions in dealing with the
smaller, hardcore, persistent criminal element that is
responsible for a disproportionate amount of crime.
Put negatively, deterrents will be relatively ineffective in
dealing with hardcore offenders and incapacitation
policies may be wasteful in dealing with those (the
population at large) who may commit crimes only
occasionally and who respond to the mere threat of
sanctions and moral persuasion (von Hirsch et al., 1999).
The “offender population” is certainly not monolithic
and a key, largely unresolved issue is the proportion of
different types of offenders who are, in fact, intractable.
It may be that the distribution of hardcore versus
occasional offenders is offence specific. For example,
more robbers than impaired drivers may qualify as
hardcore, committed offenders.
4.3Evidence on Deterrence and
Incapacitation
Research on the deterrent and incapacitative effects of
punishment in general can shed some light on the
potential preventive effects of MMS. One issue is
whether minimum penalties are actually imposed
consistently and hence increase the certainty of
punishment. Also, assuming that MMS increase
sentence length, do potential or actual offenders
differentiate between sentences of, say, five and seven
years in their decision to commit a crime? Legal
sanctions that dissuade the general population from
offending are referred to as general deterrents, while
those dissuading actual offenders from repeating their
crimes are called specific deterrents. Furthermore, do
lengthier sentences continue to provide preventive
benefits through incapacitation; or, might they provide
diminishing returns, as incapacitated individuals age
and other offenders replace them in the illicit
marketplace?
4.3.1Deterrence
There is a voluminous research literature on these
matters. Criminal sanctions have been found to carry
some deterrent and incapacitative effects (Canadian
Sentencing Commission, 1987; Nagin, 1998); however,
these effects vary according to a number of factors,
including:
1. The nature of the crime. Deterrent effects
may be crime-specific. One study, for
example, found that the increased
certainty of arrest helped lower the
burglary rate, while larceny rates were
unaffected by police efforts (Zedlewski,
1983);
2. The target group.The link between the
certainty of punishment and crime rates
may also vary according to criminal
history or race (Greenfield, 1985; Wu and
Liska, 1993). More persistent offenders
and those who have been punished in the
past are less likely to be deterred by the
threat of punishment and each
ethnic/racial group tends to respond to
the arrest probability of members of that
group, rather than to society-wide arrest
probabilities;
3. Moral prohibitions associated with the
behaviour.Those who will experience
shame or embarrassment as a result of
their involvement in a crime are less likely
to commit that crime (Grasmick, Bursik,
and Arneklev, 1993);
4. Knowledge of the pertinent sanction. The
public has little knowledge of the nature
and severity of criminal sanctions,
including those offences carrying MMS
(Canadian Sentencing Commission, 1987).
The awareness of legislative change, such
as the introduction of a MMS, is an
obvious prerequisite to its marginal
deterrent effect;
5. The certainty of punishment.Some
studies show that crime rates decline with
an increase in the probability of arrest
(Tittle and Rowe, 1974; Marvell and
Moody, 1996);
6. The celerity or swiftness of punishment
(Howe and Brandau, 1988). While little
evidence exists in relation to this factor,
learning theories suggest that the more
swiftly punishment follows a crime, the
lower the likelihood that the crime will be
repeated;
7. The severity of the sanction.While some
studies show that tough sanctions carry a
deterrent effect (Green, 1986), the
evidence relating to this factor is mixed at
best;
8. Perceptions of the risk of incurring the
sanction(Klepper and Nagin, 1989).
Generally, those who believe they are
likely to be caught and punished will be
less likely to commit a criminal act.

The many factors shaping the potential deterrent effect
of criminal sanctions preclude simplistic, sweeping
generalizations affirming the presence or absence of a
deterrent effect. The evidence bearing on the issue of
deterrence is very complex and incomplete. Hence,
extreme positions either denying the existence of any
deterrent effect of legal sanctions or suggesting that
everyone can be deterred reflect entrenched ideological
positions, rather than the empirical evidence.
The research on both sentence certainty and severity are
relevant to MMS and, on balance, the evidence suggests
that severity may be less critical to deterrence than
initiatives boosting the certainty of punishment (Miller
and Anderson, 1986; von Hirsch et al., 1999). In fact,
these elements often operate at cross-purposes as actors
within the criminal justice system have been known to
circumvent laws they believe are draconian by failing to
charge or by refusing to convict guilty defendants (Ross,
1982). Thus, excessively harsh penalties may undermine
the certainty of punishment by reducing the risk of
incarceration. Conversely, increases in the certainty of
imprisonment can produce compensating reductions in
sentence lengths. A US study of incarceration in six
states found that, for drug offences and robbery, an
increase in one was compensated for by reductions in
the other (Cohen and Canela-Cacho, 1994). As prison
capacity, at any time, is finite, increasing the rate of
incarceration for one group of offenders may necessitate
shorter sentences or early releases of other offenders.
There may be important lessons here with regard to
MMS.
As MMS often apply to repeat offenders, research on
specific deterrence, the extent to which known offenders
respond to the threat and experience of punishment, is
particularly relevant. The high recidivism rates
generally found among former prisoners and studies of
the impact of custodial sanctions on young offenders
leave little room for optimism regarding specific
deterrence (Siegel and McCormick, 1999:). The specific
deterrent effect may be limited, but it is not nil. A study
of career armed robbers who had abandoned their life in
crime revealed that one of the key factors underlying
their decision was a desire to avoid further incarceration
(Gabor et al., 1987). For some offenders, at least, there
may be a point at which they tire of punishment and its
associated privations.
A survey of 1,000 convicted felons suggests that even
serious offenders do not become completely inured to
the effects of punishment (Horney and Marshall, 1992).
The study revealed that subjects with higher arrest ratios
(self-reported arrests to self-reported crimes) also
reported higher risk perceptions, indicating that active
offenders may learn from their offending experience. In
turn, those believing that they face higher risks in
lawbreaking have been found to commit fewer crimes
(Nagin, 1999).
Public awareness of sanctions is also critical to their
value as a deterrent. People will not be deterred by a
sanction about which they have little knowledge. The
Canadian Sentencing Commission’s (1987) research
suggests a lack of awareness of sentencing laws and
practices in Canada, especially in relation to MMS. The
Latimer case illustrates this point as the jury was
unaware that murder in this country carries a mandatory
life sentence.
4.3.2Incapacitation
At first glance, estimating the crime preventive effects of
incapacitating offenders appears simple enough. The
average annual number of offences per offender must be
multiplied by the number of people in custody.
Unfortunately, the problem is complex, owing in part to
enormous variations in the estimation of individual
offending rates. Estimates using arrest records range
between 8 and 14 index crimes per year on the street,
while estimates from self-report studies demonstrate a
greater variation still. Robbers are estimated to average
between 5 and 75 robberies per year and burglars are
estimated to commit an average of 14 to 50 burglaries
per year (Nagin, 1999). Zimring and Hawkins (1995)
report that estimates of the number of crimes prevented
per year in prison ranges from 3 to 187. Even the low-
end estimates suggest that incapacitation prevents large
numbers of crimes.
Nagin points out, however, that the averages are skewed
by a small number of individuals who commit
extraordinarily high numbers of offences. Visher (1986),
for example, found that five percent of robbers
committed 180 or more robberies per year. Thus,
incapacitating the remaining 90% to 95% of offenders
will yield a much lower crime preventive benefit than
that suggested by the mean offence rate. Then there are
issues of diminishing returns with age, offender
replacement in relation to offences meeting a demand
(e.g., drug dealing) and those committed in groups, and
the possibility that incapacitation merely delays rather
than disrupts criminal careers (Vitiello, 1997).
It has been estimated that, in 1975, 32.9% of potential
violent offences were prevented nationally (in the US)
due to incapacitation alone (Cohen and Canela-Cacho,
1994). By 1989, the near 200% increase in prison
inmates, according to these authors, had prevented just
an additional 9% of violent offences, for a total of 41.9%
Research and Statistics Division 9
of potential offences. The marginal benefits of
imprisonment decline with age and once most of the
high rate offenders have been confined. A study
applying a mathematical model estimating the effects of
incarceration has corroborated this point by finding that
crime levels are quite insensitive to the size of the prison
population (Greene, 1988).
The most cost effective method of incapacitation would
involve the allocation of prison resources more
selectively, through the early identification of the most
active offender group – selective incapacitation.
Selective incapacitation, however, has drawn fierce
criticism on both ethical and pragmatic grounds. From
an ethical standpoint, sentencing exclusively according
to risk is said to violate fundamental legal principles by
allocating punishment on the basis of expected future
behaviour (Dershowitz, 1973), undermines
proportionality in sentencing (Capune, 1988), and
would likely be applied disproportionately to various
social groups (e.g., minorities, the young) (Capune,
1988; Gabor, 1985).
Practically speaking, the prediction enterprise is
essentially unable to identify high-rate career offenders
prospectively (in advance) (Petersilia, 1980; Greenberg
and Larkin, 1998). Also, studies attempting to predict
offender risk tend to have false positive rates (i.e., over-
predictions of dangerousness) of over 50% (Auerhahn,
1999). Furthemore, it is believed that many high-rate
offenders are already incapacitated under existing
sentencing practices, thereby limiting the potential
gains under a selective incapacitation policy (Beres and
Griffith, 1998; Nagin, 1998). In any event, MMS tend to
adopt a collectiverather than selectiveincapacitation
approach, as they are usually triggered by specific or
repeat offences, rather than offender-specific risk-
related attributes.
Finite prison space has implications for both
incapacitation and deterrent effects. As it is difficult to
simultaneously increase both the rate of incarceration
and the length of prison sentences, the respective
benefits of each must be considered. One study has
found that a sentencing regime involving shorter
sentences (one year) for a large offender base (all
convicted persons) is more efficient than one involving
longer sentences (four years) applied to a smaller
offender base (repeat felons) (Petersilia and Greenwood,
1978). The crime preventive yield of both strategies was
estimated to be the same, although the cost of the latter
strategy would be far more substantial in terms of the
size of the prison population.

M
andatory sentencing laws can apply to an
entire class of offences (e.g., felonies) or to just
one category of crime. In Canada, MMS apply
to both first and second degree murder, high treason,
impaired driving and related offences, various firearms
offences, betting/bookmaking, and living off the avails
of child prostitution (Appendix A). Laws applying to a
broad class of offenders are discussed in the next
section. The research literature on firearms, impaired
driving, and drug offences is examined in separate
sections due to the level of attention accorded these
offences in discussions of mandatory sentencing.
While murder carries a mandatory life sentence in
Canada, systematic evaluations of the impact of the
MMS introduced in 1976 have been conspicuously
absent. Weighing the merits of MMS relative to the
death penalty and other sanctions existing prior to 1976
would be a complex undertaking, given the confounding
influence of the capital punishment moratorium prior to
its abolition. We suggest that the case of murder be
taken up elsewhere, given the extensive literature on the
subject and the absence of MMS for murder in most
jurisdictions – including most of those with capital
punishment. While the death penalty is usually
discretionary, mandatory death penalty statutes persist
in a number of US states for life-term prisoners who
commit murder. These statutes are designed to deter
those who need an added disincentive to committing
murder as they are already serving life sentences.
Many of these statutes have been repealed by state
legislatures or struck down by state courts in keeping
with various US Supreme Court decisions since its
landmark Furmanv. Georgiaruling in 1972 (Galbo,
1985). The gradual disappearance of mandatory death
statutes, both before and after Furman, was due to “jury
nullification” (i.e., juries preferred to acquit guilty
defendants rather than impose the death penalty) and
the failure of MMS to consider mitigating individual or
offence-related factors. From the Furmanruling in 1972
to 1987, the US Supreme Court had struck down every
mandatory death penalty statute it had ruled on and has
all but explicitly deemed them unconstitutional
(Bowers, 1988). Furthermore, from an international
perspective, there is a world-wide trend toward the
abolition of capital punishment (Radelet and Borg,
2000).
5.1General Mandatory Sentencing
Laws
Gainsborough and Mauer (2000) have pointed out that
during the national decline in crime from 1991 to 1998,
US states with the greatest increases in the rate of
incarceration (often due to MMS) tended to experience
the most modest declines in crime. States with above
average increases in their incarceration rates increased
their use of prison by an average of 72% and experienced
a 13% decline in crime, while “below average” states
increased their use of prison by 30% and saw their crime
rates decline by 17%. While these findings cast doubt on
the overall preventive effect of incarceration, the
authors do acknowledge that, nationally, crime did
decline in the 1990s with increasing incarceration rates.
They did not rule out the possibility that the increased
use of incarceration may have played a role in this
decline, in addition to economic and other factors.
Further muddying this analysis was the finding that
increasing incarceration rates throughout most of the
1980s were accompanied by increases in crime.
Among the best known and most thoroughly evaluated
laws prescribing MMS has been the California “Three-
Strikes” law enacted in March, 1994. This law calls for a
MMS of 25 years to life in prison for offenders convicted
of any felony (roughly equivalent to indictable offences
in Canada) following two prior convictions for serious
crimes. The law also increases the prison sentence for
second-strike offenders, requires consecutive prison
sentences for multiple-count convictions, and limits
good-time credits to 20% following the first strike. These
laws have proliferated and assumed various
incarnations across the US, although many are modelled
on the California version. They are based on criminal
career research, beginning in the 1970s, pointing to the
disproportionate involvement in violence of a hardcore
group of chronic offenders (e.g., Wolfgang, Figlio, and
Sellin, 1972). The policy implications of these studies
appeared clear: the incapacitation of these chronic
offenders could occasion major reductions in crime.
Projections by researchers at Rand Corporation lent
optimism to the California law (Greenwood et al., 1996).
They calculated that a fully implemented Three-Strikes
law would reduce serious felonies by between 22 and 34
percent. Furthermore, the Rand researchers noted that
5.0 The Impact of Mandatory Minimum
Sentences
Research and Statistics Division 11
this expected reduction was based solely on its
incapacitation effect and did not consider its potential
deterrent effect.
Stolzenberg and D’Alessio (1997) evaluated the impact
of the law on the rates of serious (index) crimes in
California's ten largest cities. While the rate of these
crimes across these cities dropped by 15% from the 9-
year pre-implementation period to the 20-month post-
implementation period, a time-series analysis
conducted by the authors suggests that this reduction
was due to a declining trend in these offences already
underway before the law was enacted. The authors did
find a significant effect in one of the ten jurisdictions. It
is also noteworthy that the drop in index crimes in the
post-implementation period exceeded by a wide margin
the drop in petty theft during the same period. Petty
theft served as a control as it was expected to be
unaffected by the legislation. While the findings
appeared to provide mixed support for the Three-Strikes
law, the authors speculated about its limited effect on
serious crime. One explanation offered was that
California’s sentencing system already called for
enhanced (longer) sentences for repeat offenders;
therefore, many high-risk offenders were already behind
bars prior to the new law’s enactment. Secondly, the
authors conjectured that the third strike will often occur
at an age when criminal careers are on the decline,
thereby limiting the law’s impact.
Another short-term analysis of the impact of California’s
Three Strikes law indicated that major crime dropped
more sharply in the state than it did nationwide (Vitiello,
1997). In the first year of the law (1994), crime in the
state dropped by 4.9%, compared to 2% in the US as a
whole. In the second year, California's major crime rate
dropped by 7% as opposed to a 1% reduction
nationwide. While these findings are noteworthy, no
systematic attempt has been made to examine the role
played by the law as opposed to economic and
demographic factors.
Austin (1993) found that in four states with sentencing
guidelines and enhancements (Pennsylvania, Florida,
Minnesota, and Washington), the crime trends were
similar to national trends. Wichiraya (1996) examined
31 states that have implemented some sentencing
enhancements and found no significant declines in
crime rates in most of these states and even increases in
a few cases. Maxwell (1999) notes, however, that such
studies should not be interpreted as an indication of the
failure of MMS to reduce crime rates. As MMS apply to
only a fraction of those entering the justice system, they
are likely to only marginally affect crime rates. As of
August, 1998, of the 22 states adopting Three-Strikes
laws, six or less individuals had been sentenced under
these laws in eight states (Schultz, 2000). Only in
California have these laws been applied to a sizable
group of offenders. Furthermore, 85% of those
convicted under California’s law were nonviolent or
drug offenders, thereby limiting the laws ability to
prevent violent crime.
A spate of fatalities in Western Australia, stemming from
car pursuits often involving young offenders with stolen
vehicles, resulted in the enactment of the Crime (Serious
and Repeat Offenders) Sentencing Act 1992 (Broadhurst
and Loh, 1993). The most controversial aspect of the
Act was an 18-month mandatory prison term for those
convicted four times within a period of 18 months for a
violent offence or convicted seven times, with the
seventh being for a serious offence. The sentence was
both mandatory and indeterminate, as release following
the 18-month period required approval by the Supreme
Court, in the case of juveniles, and by the Governor, in
the case of adults.
The authors first provided a general critique of the Act,
arguing that it offended the principle of proportionality
by relying excessively on the offender’s criminal record,
embraced preventive detention, and adopted the
dubious strategy of selective incapacitation. Due to the
poor quality of Western Australian juvenile offending
records, the authors asserted that accurate estimates of
the number of individuals likely to be subject to the
legislation were not possible. Using South Australian
data, it was predicted that between 1.3% and 3.2% of the
juvenile population would be subject to the Actwithin 12
months of its implementation. South Australian cohort
data indicated that there was no empirical basis to the
idea that the four or seven offence threshold triggering
the legislation would capture the most persistent
offenders. Sixteen months following its
implementation, only two offenders had been sentenced
under the Act. The authors attributed its lack of
application to the vagueness of the Actregarding the
meaning of a prior offence and reluctance on the part of
key players in the justice system to enforce it. The
infrequent application of the Actmakes it unlikely that,
as enforced, it could yield a significant incapacitation
effect. Also, observed declines in car thefts and chases
around the introduction of the law were found to be
short lived and were viewed as resulting from changes in
police practices and factors other than a deterrent effect.
Morgan (2000), also in Western Australia, examined the
impact of a 12-month MMS for a third home burglary
offence. Enacted in November, 1996, the law was not
accompanied by a significant reduction in reported
home burglary offences when the pre-intervention
MANDATORY MINIMUM PENALTIES
12 Research and Statistics Division
(1991-96) and post-intervention (1997-98) periods were
compared. Although claims have been made that just a
small proportion of those serving these MMS and
subsequently released committed a further burglary,
Morgan asserts that these claims were based on an
analysis with a very small sample (57 cases) and plagued
by other methodological flaws.
Chief Justice Rehnquist (1993) of the US Supreme Court
has observed that MMS allocate scarce prison space to
low-level criminals (e.g., the “mules” in drug trafficking)
for long periods, rather than those directing criminal
activity. Hence, the costs of these penalties are
substantial and their benefits, in terms of crime
reduction, are few.
To summarize, the evidence was mixed in terms of the
effectiveness of more general mandatory sentencing
laws such as “Three Strikes.” Some studies show modest
crime preventive effects. California’s Three Strikes
legislation has been the most extensively researched of
these initiatives. While that state experienced a sharper
decline than other states following the law’s
implementation, communities in California showed
inconsistent effects. Also, studies comparing states with
and without such a law showed no difference in their
crime trends. Reasons given for the lack of a more
pronounced effect of such sweeping laws include their
inconsistent application, the small number of
individuals to whom these laws apply, and the
possibility that the most serious and persistent offenders
already tend to be serving long sentences under existing
legislation.
5.2Mandatory Sentences for Firearm
Offences
Over half of the mandatory sentencing provisions in
Canada deal with firearms offences. These provisions
were first introduced in 1977 and have been amended
with the enactment of Bill C-68 in December, 1995.
Section 85 of the Criminal Codecalls for a one-year
minimum penalty for using a firearm during the
commission of an offence and a three-year MMS for
subsequent convictions. These penalties are to be
served consecutively to any other sanction imposed for
the primary offence. Bill C-68 introduced ten four-year
minimum sentences for serious crimes, such as
manslaughter, sexual assault, robbery, and kidnapping
(Appendix A).
Surveys of armed robbers conducted in Western
Australia suggest that gun robbers consider the threat of
punishment in general and MMS in particular (Harding,
1990). Harding found that 73% of his small sample of 15
gun robbers had actively considered the possibility of
being caught. Two-thirds of the gun robbers
interviewed stated that they thought about the
consequences of carrying a weapon and all but one said
that they knew weapon use carried a longer maximum
penalty in Western Australia. Gun robbers were more
likely to be aware of the penalties and to consider the
consequences of their crimes than were robbers not
using firearms, suggesting that such individuals might
be most responsive to MMS. Notwithstanding this
rationality, Harding found that virtually all the gun
robbers said that they would carry a gun next time they
committed a robbery. This study revealed an interesting
divergence, seen in many contexts, between perceptions
of risk and behaviour. Just as smokers may persist in
their habit despite their awareness of the risks, offenders
reflecting on the risks of using a gun may nevertheless
continue to use firearms due to habit, the sense of
security they afford, or other reasons. Thus, awareness
of penal sanctions (including MMS) is no guarantee that
offender behaviour will be modified by them.
The 1977 legislation imposing a one-year MMS for use of
a firearm during an offence was accompanied by a
decrease in the proportion of homicides and robberies
in which firearms were used (Scarff, 1983). However,
the Scarff evaluation study was fraught with a number of
methodological shortcomings and acknowledged that
there may have been a compensating increase or
displacement to homicides and robberies not involving
firearms (Gabor,1994b).
A study by Meredith, Steinke, and Palmer (1994)
assessed the application of the one-year MMS provided
for under Section 85. The study relied on data from the
Canadian Police Information Centre (CPIC) regarding
charges laid under Section 85 and the sentences
imposed for those convicted. The authors called for
caution in the interpretation of their findings due to a
number of limitations of the database (e.g., missing
records, under-representation of dual/hybrid and
summary offences, differing reporting practices among
police departments). The study revealed that
approximately two-thirds of the charges laid under
Section 85 were stayed, withdrawn, or dismissed. The
primary offence in half the cases was robbery and the
sentence imposed most frequently for convictions under
Section 85 was a one-year period of incarceration. The
average prison sentence imposed was 16.4 months
where the Section 85 offence was imposed consecutively
to the primary offence. In some cases, the firearms
offence was imposed concurrently to the substantive
offence. No quantitative analysis was undertaken to
determine the effect of the MMS on sentence length;
Research and Statistics Division 13
however, police, Crown prosecutors, and judges
interviewed in the study believed the effect was minimal
or none at all. The interviews also showed that there
were no written policies to guide police in laying charges
under Section 85.
In the 1970s, a number of American states enacted MMS
for firearms offences. Several studies examined the 1975
Massachusetts Bartley-Fox Amendment that provided
for a one-year MMS for illegally carrying a firearm (Beha,
1977a; Beha, 1977b; Deutsch and Alt, 1977; Pierce and
Bowers, 1990; and Rossman et al., 1980). The
assessments of the Amendment were mixed. While Beha
found little evidence of a preventive effect, Pierce and
Bowers found that homicides, gun assaults, and armed
robberies declined, but other assaults and robberies
increased – a possible substitution effect. Deutsch and
Alt's evaluation revealed a decline in robberies and
assaults committed with firearms, while failing to show
an effect for homicide. They did not explore the
possibility of a displacement to similar crimes
committed without guns. Many of these studies were
characterized by short follow-up periods (e.g., six
months). Tonry (1992) has suggested that some of
Bartley-Fox's shortcomings may have been due to the
greater selectivity of the police in their searches
following the Amendment. In addition, the Amendment
was accompanied by a major increase in the number of
firearm confiscations (without arrest), as well as in case
dismissals and acquittals. By undermining the certainty
of punishment, these factors may have jointly lessened
the effect of the law.
The Michigan Felony Firearms Statute of 1977 provided
for a two-year minimum sentence for possession of a
firearm during the commission of a felony to be served
consecutively to the primary offence. Evaluations of this
legislation revealed little evidence of a deterrent effect
(Heumann and Loftin, 1979; Loftin, Heumann and
McDowall, 1983). There was evidence that the statute
was circumvented both by increases in case dismissals
and by the tendency of the courts to undermine its
intent by imposing the same overall sentence as was the
case prior to its introduction.
McDowall, Loftin and Wiersema (1992) analyzed the
effects of MMS for firearms offences in six American
municipalities – Detroit, Jacksonville, Tampa, Miami,
Philadelphia, and Pittsburgh. Aside from undertaking
separate analyses in these cities, the authors pooled the
results from these cities to obtain an estimate of the
impact of these laws across the six jurisdictions.
According to the authors, the laws had sufficient
common elements to justify combining the data from
the six cities. Each law required judges to impose a
specific sentence for an offence involving a gun and
prohibited mitigating devices, such as suspended
sentences and parole. In addition, each of these laws
was accompanied by a major publicity campaign. The
authors compared gun and non-gun homicides,
assaults, and robberies to ascertain the impact of these
laws, using sophisticated time-series designs that
monitored the rates of these crimes from 54 to 150
months prior to each law.
The separate analyses yielded mixed results. Gun
homicides decreased in all six cities, significantly in four
and insignificantly in two. Gun assaults declined in two
cities and some effect was observed for armed robbery in
two other cities. In the pooled analysis, a very strong
effect was observed for gun homicide across the six
cities, while little change was observed for non-gun
homicide. There was no evidence that gun assaults were
prevented by the statutes and there was some evidence
that these laws may have prevented armed robberies
from increasing as non-gun robberies increased
following their enactment while gun robbery rates
remained unchanged. Thus, the MMS seemed to have a
preventive effect with regard to gun homicide and,
possibly, armed robbery. The authors acknowledge that
caution must be exercised in drawing conclusions from
this study as the cities included were not necessarily
representative of those adopting MMS for gun-related
crimes. Also, no comparisons were made with cities
without such laws to determine whether gun-related
violence declined nationally, rather than as a result of
the MMS.
An Arizona firearm sentence enhancement law enacted
in 1974 was followed by highly significant reductions in
gun robberies in two large counties, with no evidence of
displacement to other robberies or property crimes
(McPheters, Mann, and Schlagenhauf, 1984). The
authors also found no significant gun robbery reduction
in five other southwestern cities used as controls. They
nevertheless noted that the reduction might have been
due to a return of robbery rates to historical trends after
they peaked in the two years prior to the law.
Marvell and Moody (1995) conducted regression
analyses to assess the effects of firearm sentence
enhancements on prison populations and crime across
the 49 US states that have passed such laws. The study
found no consistent effect on prison populations and no
significant impact on gun homicide. There was also no
evidence of a shift to other homicides. There was little
evidence overall that other crimes were affected by these
laws. In just three of the states did these laws appear to
produce more imprisonment the year following
implementation, along with less crime and gun use.
MANDATORY MINIMUM PENALTIES
14 Research and Statistics Division
Such analyses are confounded by many other social and
policy-related factors influencing both incarceration
rates and gun use in crime. Furthermore, the firearm
laws in the various states took many forms, making
generalizations difficult.
To summarize, MMS for firearms offences show
promise, although the findings are inconsistent or
unclear. In Canada, a major evaluation of the one-year
mandatory prison sentence for the commission of a
crime with a firearm, introduced in 1977, indicated that
a modest decrease in the proportion of homicides and
robberies involving a firearm had occurred. There was
some evidence, however, that there was a displacement
or shift to offences committed by other weapons. This
evaluation was plagued by a number of serious
methodological shortcomings that preclude more
definitive statements about the law’s impact. Another
study found that the one-year MMS has been applied
inconsistently and has not increased sentence length as
judges appear to provide a “going rate” for crimes. Thus,
judges do not appear to regard the one-year MMS as an
enhancement or add-on to the sentence imposed for the
primary offence.
In several American jurisdictions, similar laws have been
accompanied by reductions in gun homicides and/or
robberies. The most extensively researched law was
Massachusetts’ Bartley-Fox Amendment, which called
for a one-year mandatory prison term for carrying a gun
illegally. The evidence was mixed on the impact of this
Amendment on crime. It has been suggested that
adaptive behaviour by the police may have undermined
the law, as searches of suspects became more selective
and informal remedies (e.g., the confiscation of guns
without charges) became more commonplace.
An Australian study was particularly discouraging for
proponents of MMS and deterrence in general, for this
category of offender at least. Gun robbers in that study
indicated that they would continue to use firearms in
their offences despite their knowledge of mandatory
terms for criminal gun use and despite their
consideration of the consequences of their crimes.
5.3Mandatory Sentences for
Impaired Driving
In Canada, impaired driving infractions carry a
minimum penalty of 14 days for a second conviction and
90 days for any subsequent conviction. While MMS in
this area have proliferated in North America since 1980,
few evaluations have assessed them directly.
There are indications that those committing this
infraction may be sensitive to the certainty of
punishment, as police crackdowns have been quite
successful in reducing incidents of this offence
(Sherman, 1990). Furthermore, research in which
impaired driving scenarios were presented to subjects
has shown that persons who perceived that sanctions
were more certain or severe reported lower probabilities
of their engaging in the behaviour (Nagin and
Paternoster, 1993). At the same time, Taxman and
Piquero (1998) have found that treatment-oriented
sentences for impaired driving offenders may reduce
recidivism rates more than punitive sentences. For first-
time offenders, these investigators found that less
formal punishment (e.g., probation terms in which
convictions are expunged if successfully completed) was
the most effective in deterring impaired driving. In
general, isolating the effects of punishment versus
treatment is rendered difficult by the infrequency of
incapacitation for impaired drivers, as well as the fact
that punitive sanctions often include education and
treatment measures (Yu, 1994).
Nienstedt (1990) attempted to isolate the effects of a
tough law from the effects of the publicity
accompanying it using a sophisticated research design.
The law in question was enacted in Arizona in 1982 and
called for MMS, as well as a prohibition on diversion and
plea bargaining in the case of impaired driving
infractions. Five months before the enactment of the
law, major media campaigns were initiated in Phoenix
and Tucson, Arizona’s two largest cities. Aside from
advertisements in both the electronic and print media,
the media campaign generated a flurry of articles and
programs on the subject. The impaired driving initiative
was also publicized through posters, billboards,
brochures, and bumper stickers. The publicity not only
featured the legislation that was about to be introduced
but promised increased resources for traffic
enforcement. No additional resources were actually
allocated. The study revealed that the reduction of
accidents, including those involving alcohol, was much
greater following the publicity campaign than after the
enactment of the impaired driving law. Furthermore,
once the effect of the publicity was statistically
controlled, the law’s effect on accidents vanished. An
analysis of the law’s implementation showed that court
backlogs undermined the law’s prohibition of plea
bargaining, as impaired driving offences were routinely
reduced to loitering. The author concluded that
publicity campaigns may be a less costly and more
effective alternative to largely symbolic MMS.
Grasmick, Burski Jr., and Arneklev (1993) examined the
relative importance of legal sanctions and moral
Research and Statistics Division 15
prohibitions in curtailing impaired driving. They noted
that moral crusades in the 1980s, spearheaded by groups
such as MADD (Mothers Against Drunk Driving) and
SADD (Students Against Drunk Driving), underscored
the growing unacceptability of this activity. The
researchers randomly sampled 332 Oklahoma City
adults in 1982 and another 314 adults in 1990, probing
their level of impaired driving, the shame associated
with it, and their anticipated embarrassment if caught.
The surveys revealed a significant decrease, from 1982 to
1990, in the number of respondents who had driven
drunk in the last five years and who indicated they
would do so in the future. Anticipated feelings of shame
or remorse increased significantly. There was also an
increase in the perceived certainty and severity of legal
sanction, as well as some increase in the perceived
certainty of embarrassment. While the threat of legal
sanctions was found to be an important deterrent,
anticipated shame was determined to be the primary
deterrent.
Kenkel (1993) used data derived from the 1985 Health
Interview Survey (US) to determine whether self-
reported drinking and impaired driving patterns were
related to state laws governing these behaviours. Nearly
12,000 males and 16,000 females participated in the
survey. State laws, including MMS, were found to have a
deterrent effect upon heavy drinking and impaired
driving. States with tougher laws, more sobriety checks,
and heavier taxes in relation to alcohol were
characterized by lower levels of these behaviours.
Kingsnorth, Alvis and Gavia (1993) examined whether
increases in the severity of penalties for impaired driving
in Sacramento, California affected recidivism rates.
Over 400 cases were examined for each of three years
1980, 1984, and 1988. In 1980, there were no written
court policies in dealing with impaired driving
infractions. In 1984, MMS were introduced, including a
combination of fines, jail time or license restriction,
probation for a first offence, and a mandatory jail
sentence and other enhancements for subsequent
convictions. In 1988, the fines, financial penalties and
other provisions became more severe than in 1984. The
authors found that recidivism rates over the ten-year
study period (1980-90) did not decline with the
increasing severity of penalties.
Yu (1994) examined the files of almost fourteen
thousand New York State drivers with an impaired
driving conviction record in order to identify the
sanctions most likely to exercise a deterrent effect. The
author found that increases in fines reduced recidivism
significantly. Yu found that license withdrawals, which
were mandatory but could vary in length, did not show
an effect on recidivism. He conjectured that license
actions imposed fewer consequences on impaired
drivers, as these measures would not necessarily prevent
them from driving. Yu further found that the celerity or
swiftness of punishment was not an important factor, as
the intervals between arrest and conviction tended to be
long. Also, he speculated that impaired driving was a
unique offence in that repeat offenders, by virtue of their
substance abuse, did not respond to swift punishment.
Grube and Kearney (1983) evaluated the impact of a
two-day mandatory jail sentence, enacted in 1979 in
Yakima County (Washington) for anyone convicted of
impaired driving. They found that alcohol involvement
in fatal accidents occurring in the county did not change
significantly following the introduction of the MMS; nor
was such involvement lower in the county than in the
state as a whole. One reason cited for the apparent
failure of the law to reduce the role of alcohol in fatal
accidents was the finding that 40% of residents were
unaware of the mandatory penalty.
Ross and Voas (1990) assessed the effects of sentence
severity on impaired driving in the neighbouring cities
of New Philadelphia and Cambridge, Ohio in May, 1985.
The cities were similar economically and
demographically. In Cambridge, impaired drivers were
dealt with more traditionally – their jail sentences rarely
exceeded the state minimum of three days and their
sentences were usually served in education-oriented
weekend camps rather than in the county jail. By
contrast, in New Philadelphia, the sole judge imposed a
“standard” jail term of 15 days, a $750 fine, and a six-
month license restriction on first offenders. Surveys
conducted in the two cities indicated that New
Philadelphia residents did perceive the certainty and
severity of penalties to be greater than in Cambridge.
Despite the differences in both actual and expected
punishments, no significant differences were found in
the levels of impaired driving in the two cities as
indicated by random breath tests. A study of court files
indicated that the re-conviction rate, too, was similar in
both cities and therefore unaffected by the harsher
penalties in New Philadelphia. The authors concluded
that increasing sentence severity did not serve as a
deterrent without a concomitant increase in the
certainty of punishment.
To summarize, the deterrent effects of MMS for
impaired driving are especially difficult to assess as
these legislative initiatives are usually accompanied by
educational campaigns. In addition, legal sanctions are
often accompanied by treatment for alcohol abuse.
Research attempting to isolate the effects of legal
sanctions has found that people are more likely to
MANDATORY MINIMUM PENALTIES
16 Research and Statistics Division
respond to the shame associated with impaired driving
than to the threat of punishment per se, although the
level of shame is undoubtedly influenced by sanctions
and publicity campaigns. Overall, the evidence in this
area holds out more hope for vigorous law enforcement
and the certainty of punishment than for tough
sentences. Studies indicate that MMS and sanctions of
increasing severity do not reduce recidivism rates or
alcohol-related accidents. One author has noted that
impaired driving often involves substance abuse which,
in turn, cannot be adequately dealt with through
punishments alone.
5.4Mandatory Sentences for Drug
Offences
The most extreme manifestation of MMS for drug
offences can be seen in Malaysia. In 1975, the Malaysian
Parliament imposed a mandatory life sentence for drug
trafficking and, in 1983, a mandatory death penalty was
introduced for this crime (Harring, 1991). Over 200
death sentences were imposed between 1985 and 1989.
However, the conviction rate has declined by 30%
during those years and many charges are being dropped
by the police and Public Prosecutor. In many cases,
charges are being used as leverage to gain the
cooperation of defendants. Also, in 1989, appellate
judges began to reduce death sentences to life. The
judiciary has developed a number of legal devices to
spare defendants from the death sentence, including
their conviction for drug possession rather than
trafficking. The author asserts that the Malaysian
experience demonstrates the limitations of a “drug war
model in dealing with the drug problem. Despite over
100 executions and many more death sentences
imposed, as well as more aggressive tactics by police,
drug use and trafficking remain serious social problems.
This case provides another illustration of adaptive
behaviour on the part of actors within the justice system
in circumventing a law regarded as excessively harsh,
inflexible, and overly cumbersome to enforce.
In the United States, the Anti-Drug Abuse Actsof 1986
and 1988 prescribed harsh minimum penalties at the
federal level (Spencer, 1995). In 1986, a 5 to 40-year
sentence, without probation or parole, was mandated
for first offenders convicted of possession with intent to
distribute small quantities of designated substances.
The sentence was 10 years to life for larger quantities.
The 1988 Amendments increased MMS, imposed these
sentences for even smaller quantities, and prescribed
especially tough sentences for first-time offenders
possessing crack and other cocaine-based substances.
Congressional debates revealed a view of drug offenders
as essentially non-human and as not responding to
deterrents. As a consequence, the focus of legislation
turned to long-term incapacitation. Surveys in the 1990s
indicate that illicit drug use remains at a high level in the
US – there are about 12.5 million cocaine, hallucinogen,
and heroin users annually – and many crimes continue
to be drug-related. At the same time, Spencer notes that
convictions and the length of sentences have increased
sharply for drug offenders between 1980 and 1990, while
the average length of sentences for other crimes has
decreased. In 1990, the majority of federal prisoners
serving MMS were first-time offenders. Furthermore,
many were low-level, non-violent individuals. From a
utilitarian perspective, the federal system appears to be
incarcerating the wrong people; individuals who are
easily replaced in the illicit market. Spencer argues that
low-level drug offenders may not even consider
imprisonment as punitive, due to the privations they
experience in the community.
Some of the most sophisticated research in this area has
been undertaken at the Rand Corporation (Caulkins et
al., 1997). Through various mathematical models, Rand
researchers compared the cost effectiveness of various
drug prevention/control strategies, including lengthy
MMS. Their analyses considered the cost of each
strategy and the expected yield in terms of both drug
consumption and crime reductions. Their conclusion
was that conventional sentences imposed on dealers are
more cost effective than long MMS reserved for fewer
offenders and that treating heavy users is more cost
effective than either approach in lowering drug use or
drug-related crime. MMS were found to be the most
cost effective strategy only in the case of the highest-
level dealers; however, the low thresholds at which MMS
tend to kick in means that these laws are more likely to
ensnare low-level offenders. Also, high-level dealers are
more likely to avoid MMS, as they are in a better position
to have information to trade for an exemption from
these penalties. Finally, these investigators note that the
time horizon of evaluations is critical, as MMS become
less cost effective over time.
Hansen (1999) asserts that the tide is turning against
MMS for drug infractions. He notes that they have done
little to reduce crime or to put large-scale dealers out of
business. Rather, they have filled prisons with young.
low-level, non-violent individuals at great cost to
taxpayers. Hansen points out that, in Massachusetts,
84% of inmates serving mandatory drug sentences are
first-time offenders.
Two Milwaukee field studies, involving interviews with
street gang leaders and members, shed some light on the
potential impact of severe and mandatory penalties for
Research and Statistics Division 17
drug offences (Hagedorn, 1994). These studies reveal
that gangs involved in dealing drugs are anything but a
monolith. In fact, most gang members are involved
intermittently in this activity, financial rewards tend to
be modest (one-third earned about the minimum wage),
and most of these dealers would opt for a conventional
lifestyle and work, if that option was available. Others
sell to support their habits and just a fraction of gang
members are committed to selling drugs as a career.
MMS fail to discriminate between these hardcore drug
dealers and those who feel compelled to sell due to an
addiction or difficulties encountered in participating
steadily in the work force. The implication is that
employment opportunities, more accessible drug
treatment, and alternative sentences would be
preferable to the “iron fist of the war on drugs.
Harsh MMS and the “drug war” approach in general
show little effect in relation to drug offences. Judges
routinely circumvent the “mandatory” death sentences
for drug trafficking in Malaysia and the tough MMS in
the US have imprisoned mostly low-level, nonviolent
offenders. MMS do not appear to influence drug
consumption or drug-related crime in any measurable
way. A variety of research methods concludes that
treatment-based approaches are more cost effective
than lengthy prison terms. MMS are blunt instruments
that fail to distinguish between low and high-level, as
well as hardcore versus transient drug dealers.
Optimally, it would appear that tough sentences should
be reserved for hardcore, high-level dealers, while
treatment may be more appropriate for addicted dealers
and employment opportunities may be more cost
effective in relation to part-time dealers who are
underemployed.
5.5Estimating the Effects of
Hypothetical Mandatory
Sentences
Brown (1998) assessed the potential impact of MMS
through an analysis of the characteristics of a national
sample of 613 offenders released from New Zealand
prisons during 1986. These offenders had been either
released halfway through their sentences on parole or at
two-thirds of sentence on remission. A subsequent two
and one-half year follow-up suggested that the marginal
incapacitation effects of additional confinement during
the post-release period would have been modest. Just
five percent of the sample were convicted for a serious
offence during the follow-up period. Furthermore,
three-quarters of these individuals had been imprisoned
for non-violent offences – offences that would not have
predicted the serious offences of those who did
recidivate nor have warranted additional confinement.
In Franklin County, Ohio, investigators studied the
criminal records of 342 individuals arrested for violent
felonies in 1973 to determine whether that offence could
have been prevented by a five-year MMS for a previous
juvenile or adult felony conviction (Van Dine, Dinitz,
and Conrad, 1979). Over half of these offenders were
found to have no previous felony conviction. According
to the authors’ calculations, a five-year MMS imposed
for violent felonies in the five years leading up to 1973
would have reduced the 1973 felony rate in the county
by just 1% to 4%. A re-calculation of the figures, using
more generous assumptions, yielded a 15% reduction in
the felony rate (Boland, 1978). The Ohio study
underscored the notion that, each year, many new
offenders come to the attention of the justice system. In
Michigan, Johnson (1978) further found that only about
24% of those arrested for violent offences had a previous
violent felony conviction. Harsh incapacitation policies
would be most effective where most crime was confined
to a relatively small and specialized (e.g., exclusively
violent) offender group.
In a Swedish study of all persons born in 1953 and living
in the Stockholm area in 1963, Andersson (1993)
estimated the crime preventive effect that would be
achieved if a two-year MMS was imposed for anysecond
criminal offence. He concluded that 28% of all
sentences for crimes would be prevented, while the
prison population would increase by 500%. Such a
policy would bring Sweden near the top of the list of
nations in terms of its per capita prison population
(Mathiesen, 1998). Furthermore, Mathiesen contends
that the preventive effect would be far more modest as
Andersson’s calculation fails to account for undetected
offenders, the substitution of prevented crimes by
others, the adverse effects of incarceration on post-
release behaviour, and the entry into crime by new
cohorts of offenders.
One major concern with MMS based exclusively on the
commission of a set number of designated offences (i.e.,
collective incapacitation) is that they are applied to
individuals across the entire risk spectrum. Hence, false
positives, the false assumption that those receiving such
penalties will repeat their crimes if not incarcerated,
tend to be problematic. Even if we accept Andersson’s
very liberal estimates of crime preventive gains from
blanket MMS for all second offenders, a 28% reduction
in known crimes would require a five-fold increase of
Sweden's prison population – an increase from 5,200 to
26,000 inmates. Many low risk offenders would be

ensnared in the web of such sweeping legislation,
exacting a massive economic and human toll.
The inefficiency and costs seemingly associated with
collective incapacitation strategies have led
investigators to project the preventive effects of
sentencing strategies that would consider individual risk
factors. A subsequent study by Andersson revealed that
if a MMS was also imposed on the basis of criminal
history and prior drug use/offence data, 44.5% of those
predicted to be poor risks would actually be false
positives. Such selective incapacitationstrategies try to
refine incapacitation policies and make them
economically more feasible.
One of the best known efforts to develop an effective and
parsimonious incapacitation strategy was that of
Greenwood and Abrahamse (1982) at the Rand
Corporation. Using a self-report study on a large inmate
sample, the authors classified the inmates into high,
medium, and low-rate offenders. They then developed a
prediction instrument to identify high-rate offenders.
Predictors included age of onset of criminality,
substance abuse, and employment history. Their
hypothetical scheme involved the incarceration of just
the high-rate offenders. The propriety of predictors
such as employment history has been questioned (Beres
and Griffith, 1998). This issue aside, the authors
estimated that the implementation of their prediction
scheme could reduce the California robbery rate by 15%,
while simultaneously reducing the number of
incarcerated robbers by 5%. Their scheme correctly
classified offenders as low, medium or high rate just 51%
of the time, meaning that prediction errors occurred in
49% of the cases. Reanalyses of their data place the false
positive rate (i.e., the rate at which individuals are
erroneously predicted to be high-rate offenders) at over
50% (Visher, 1986). Auerhahn (1999) replicated the
Rand study using a more current sample of 2,188
California state prison inmates. Using a very similar
prediction instrument, her studied improved predictive
accuracy to just 60%. Even so, just slightly over a third of
those predicted to be high-rate offenders were correctly
classified – i.e., were actually found to be high-rate
offenders.
Another predictive instrument developed by the
Institute of Law and Social Research in Washington
identified 200 “chronic offenders” from a sample of
1,708 federal parolees in the US (cited in Mathiesen,
1998). Eighty-five percent of those predicted to be
chronic offenders recidivated during a five-year follow-
up, while 35% of those predicted to be non-chronic
offenders recidivated. The results therefore improved
over the Rand study in terms of false positives, but
revealed a problematic number of false negatives (i.e.,
those predicted to be low-rate offenders who
recidivated).
Estimates of the potential crime preventive effects,
through incapacitation, of several hypothetical
mandatory sentencing policies triggered by a violent
crime indicate that the benefits would be modest
relative to the substantial prison costs. This is due to
low reconviction rates on further violent offences during
the time these penalties would be in effect. Blanket or
collective incapacitation strategies would needlessly
incarcerate many individuals not at risk of reconviction.
Selective incapacitation strategies aimed at high-rate
offenders would be more efficient; however, they are
plagued by prediction errors.

6.1General Disparities and the Shift
from Judicial to Prosecutorial
Discretion
O
ne rationale for MMS is that excessive judicial
discretion in sentencing results in unacceptable
disparities. Scholars dealing with the issue of
disparity have distinguished between that which is
warranted and unwarranted. The “unwarranted” form
refers to disparities in sentencing that are not accounted
for by offender or offence characterisitics. Tonry (1996)
has shown that such disparities are an international
problem. Roberts (1999:156) has demonstrated that
there is “substantial cross-jurisdictional variation” in
sentencing in Canada. Furthermore, Palys and Divorski
(1986) have documented the presence of unwarranted
sentencing disparities through the presentation of a
number of scenarios to judges from across Canada.
David Daubney, a former MP who headed the House of
Commons Committee on Sentencing and Parole in 1988,
stated, “Clearly, the kind of disparity we’re seeing is
unacceptable and doesn’t do anything for the public
image of the criminal justice system” (quoted in Roberts,
1999:156). Proponents of MMS assert that these
penalties can minimize such disparities.
Experience with MMS in the US, however, has shown
that reducing judicial discretion may merely shift it to
police and prosecutors. The police have the power to
arrest an individual or let him/her go with a warning.
Prosecutors have the power to proceed, dismiss, or stay
a charge. Wallace (1993:13) has argued that by removing
discretion from the sentencing process, MMS have
“succeeded only in shifting it ... from the judge, in public
proceedings conducted on the record in the courtroom,
to the prosecutor’s office, off the record and behind
closed doors.” The lack of openness and accountability
of charging and plea negotiation processes may
undermine the integrity of the entire sentencing
process. Judges, according to Wallace, have been so
limited in their discretion that they have been
compelled, at times, to impose wildly disproportionate
sentences.
One example of such a sentence is provided by a case in
the UK in which a secondary participant in a robbery
received a mandatory life sentence under the Crime
(Sentences) Act of 1997, as a result of a previous
conviction, while the primary participants (lacking a
prior record) were given five-year prison terms (Davies,
2000). Furthermore, considerable disparities have been
introduced in the US federal system by conferring upon
prosecutors the power to unilaterally reward a
defendant’s cooperation. The defendant’s “substantial
assistance” in prosecuting somebody else is the only
statutory basis for a judge to sentence below a MMS. US
Attorneys can define “substantial” as they wish and the
beneficiaries of this discount tend to be high-level,
rather than small-scale, offenders.
One US federal prosecutor has argued that the reduction
of judicial discretion brought about by MMS occurred as
a result of grossly inadequate sentences imposed by
judges on serious offenders (Baylson, 1993). Such
inadequate and disproportionate sentences and the
resulting mistrust of the judiciary prompted legislators
to enact MMS to ensure the incapacitation of the violent.
Baylson adds that exemptions from MMS accorded
offenders who provide “substantial assistance” in the
prosecution of others allows for the capture,
prosecution, and sentencing of co-conspirators who
would otherwise evade detection. This lever available to
the prosecution yields a net benefit as more high-level
offenders are neutralized. Finally, Baylson notes that
MMS do not increase prosecutorial discretion – the
discretion relating to seeking indictments for multiple
levels of crime has always existed – but merely adds
teeth to prosecutorial decisions.
Harris and Jesilow (2000) examined the implementation
of the 1994 “Three Strikes” legislation in six California
counties. Interviews were conducted with a total of 96
prosecutors, defence attorneys, judges, high-ranking
court administrators, and support personnel. In
addition, 226 questionnaires sent to judges, district
attorneys, and public defenders across the six counties
were analyzed. The study revealed that judges routinely
offered second-strike defendants the lowest possible
sentence in return for a guilty plea and the district
attorney partially nullified the law in one county as he
would file Three Strikes cases only when the current
offence was serious or violent. The study also showed
the critical role played by prosecutors in determining
the presence of past “strike” convictions in a case.
Prosecutors ignore or count the past conviction,
depending on whether they believe the case deserves
leniency. Approximately 70% of the judges and 90% of
the public defenders surveyed believed that prosecutors
6.0 Mandatory Penalties and Sentencing
Disparities
Research and Statistics Division 21
counted prior convictions as “strikes” too frequently.
These actors presumably viewed the outcome in such
cases as disproportionate relative to the attributes of the
defendant. Overall, the Three Strikes law increased
tension between courtroom actors, placed tremendous
stress upon public defenders as a result of massive
increases in trials, and led to efforts by judges to regain
control over sentencing by dismissing prior strikes in
accordance with the Romerodecision in California. The
net effect was that the predictability of case outcomes, a
principal rationale of MMS, was undermined.
The United States Sentencing Commission (1991) issued
a special report to Congress on the application of
minimum penalties. Using sentencing data covering the
period 1984-1990, the Commission found that a MMS
was not imposed in 41% of the cases in which a charge
carrying a minimum penalty was warranted by offence
and offender characteristics. In addition, the
Commission found that disparity was occurring in two
ways. First, similar defendants were being charged and
convicted differently. These differences seemed to be
based on factors such as race, circuit, and prosecution
practices. Secondly, very different defendants, in terms
of the nature of the offence and their role in it, were
receiving similar reductions below the mandatory
minimum provision.
Oliss (1995) expands upon the last-mentioned issue by
referring to drug-related provisions. He notes that
excessive uniformity in sentencing reduces disparity
only in regard to the one factor upon which the system
focuses – drug quantity. Attention to only one factor, he
adds, creates a misplaced equality that undermines the
goals of imposing consistent sentences for similar
crimes. He contends that new disparities emerge when
judges are prevented from considering the offender's
prior record, role in a conspiracy, or culpability. Sager
(1999) has further pointed out that the quantity of drugs
for which one is charged is also subject to prosecutorial
discretion, as police can lay separate charges for each
drug transaction or wait until a dealer completes several
sales and charge for the total amount of drugs involved.
A third source of disparity with regard to MMS based on
drug quantity is the large increase in sentences
associated with miniscule increases in quantity (US
Sentencing Commission, 1991). One-tenth of a gram of
cocaine (from 5.0 to 5.1 grams) can elevate a prison
sentence by four or more years under federal provisions
in the US.
Lacasse and Payne (1999) assessed the impact of the
federal sentencing reforms in the US by examining plea
negotiation and sentences in two New York State federal
district courts. The authors found that when all offences
were considered, guilty pleas actually increased from the
pre-reform period (1981-1987) to the post-reform period
(1988-1995). The guilty plea rate was the same or lower
for offences carrying MMS. As expected, sentence
lengths increased in the post-reform era. The increase
in sentence length when MMS are imposed
paradoxically creates a greater disparity between those
cases in which a defendant pleads guilty and those in
which a conviction is achieved at trial. Lacasse and
Payne found that the discount for a guilty plea was
greater after the sentencing reforms as plea sentences,
on average, were just 15% of the trial sentences.
Surprisingly, variation in sentences actually increased in
the post-reform period and were substantial across the
two districts. Furthermore, the variation in sentences
attributable to the judge increased rather than
decreased following the reforms. Thus, this study found
that the sentencing guidelines and MMS did not succeed
in removing the judge as an influence on sentences.
6.2Racial Disparity
There is a concern that MMS may be imposed
disproportionately upon members of minority groups.
Provine (1998) notes that the federal sentencing
guidelines, established in the US in 1984 to promote
equity and transparency in sentencing, have ironically
increased racial disparities. Much of this increasing
disparity has been attributed to MMS introduced in the
1980s for selected drug offences. Between 1976 and
1989, white drug arrests grew by 70%, while black drug
arrests grew by 450% (Tonry, 1996). Free (1997) has
pointed out that African Americans, who in 1990
constituted 28.2% of all federal (US) defendants in the
US, accounted for 38.5% of all federal defendants
convicted under mandatory minimum provisions.
African Americans in the federal system were also more
likely to be sentenced at or above the MMS than were
white or Hispanic defendants. Maxwell (1999)
corroborates the idea of a differential impact of MMS,
showing that the number of African Americans, both
male and female, sentenced to state or federal prisons
between 1985 and 1995 has grown at a faster rate than
the number of white Americans of both sexes.
Furthermore, Austin (1993) found that the Florida
habitual offender law was applied twice as often to black
as opposed to white offenders. In California, African
Americans constitute only 7% of the state's population
and 20% of those arrested for felonies, but they
constitute 43% of those sentenced under the Three
Strikes law (Schultz, 2000).
Free argues that much of the disproportionate impact of
MMS on African Americans has been due to the harsh
MANDATORY MINIMUM PENALTIES
22 Research and Statistics Division
sentences attached to crack cocaine offences. While
crack cocaine consumption is more likely to produce
dependence and result in criminality associated with
dependence than cocaine hydrochloride, the
physiological and psychoactive effects of the two are
similar (Hatsukami and Fischman, 1996). The
properties of crack do not appear to warrant the
substantial difference in the MMS imposed for the two
forms of cocaine. Since law enforcement efforts dealing
with the traffic in crack are concentrated in lower
income and minority neighbourhoods, African
Americans are more likely to be prosecuted for these
offences. Duster (1995) indicates that it has become an
increasingly common practice for police to intercept
citizens who fit the profile of an offender and that such
profiles have assumed a racial dimension. Also, Provine
notes that drug markets operated by blacks tend to be
more open and vulnerable to police action than the
more clandestine markets run by whites from private
premises. Furthermore, Provine asserts that the
disproportionate incarceration of black Americans is not
due to higher consumption levels as national survey
data indicate that 76 percent of illicit drug users in the
US are white.
Free adds that racial bias in prosecutorial decision-
making becomes a greater concern, as MMS shift greater
power to the prosecutorial level. Moreover, MMS are
often tied to the defendant’s criminal record and African
Americans are more likely than their white counterparts
to have prior convictions. While criminal records
themselves may reflect previous racial biases in law
enforcement, they elevate the likelihood that MMS will
be imposed on black defendants.
In Western Australia, evidence from the Children’s Court
indicates that aboriginal offenders are seriously over-
represented in three-strikes cases (Morgan, 2000). Such
over-representation is thought to be due to both the
nature of offences eligible for MMS – those often
committed by aboriginal people are more likely to be
targeted – and to the more aggressive charging practices
used in cases involving aboriginal offenders. In Canada,
MMS for various firearms and impaired driving offences
are triggered or enhanced for a second conviction. To
the extent that aboriginal defendants may be more likely
to have a criminal record in some of these areas
(Hartnagel, 2000), they will be more susceptible to the
imposition of MMS.
Aside from creating disparities in sentence length, MMS
may have a different impact upon certain minority
groups. Perera (2000) argues that MMS for property
crimes in Australia, involving the perpetrator's removal
to a remote institution, are particularly traumatic for
aboriginal people who have experienced a long history
of dislocation and dispersal.
6.3Effects of Mandatory Sentences
on Other Groups
The Crime Sentences Actof 1997 in the United Kingdom
established MMS for a second serious violent or sexual
offence, for a third drug trafficking or residential
burglary offence, and for repeat offenders (Laing, 1997).
The Actcontains a safety valve, allowing the court to
override the MMS in exceptional circumstances. In the
case of an offender with a mental disorder, the Act
authorizes the court, in its discretion, to direct an
offender who has received a prison sentence to be
admitted instead to a hospital for treatment. Objections
to imposing MMS on these offenders include the notion
that long custodial sentences for such offenders are
inappropriate and the fear that these penalties will
create an increase in insanity and related defences. A
further concern is that therapeutic interventions for
mentally disordered offenders will be thwarted.
The concern has been expressed that women may be
affected disproportionately by MMS (Canadian
Association of Elizabeth Fry Societies, 2001; Casey and
Wiatrowski, 1996). It is argued that imprisonment
places additional burdens on women, due to their
familial responsibilities, the inadequate programs
available in prisons for women, and the greater
distances of women’s institutions from their homes.
These concerns are especially germane to the situation
of Canadian women who are serving federal terms in
predominantly male institutions. The equalizing
tendency of MMS is said to create gender disparities as
sentences of equal length for men and women are
thought to weigh more heavily on the latter. Also, Raeder
(1993) points out that women in abusive relationships
may be coerced into participating in crimes and,
therefore, such mitigating circumstances ought to be
taken into account.
MMS do not necessarily stand to reduce disparities in
sentencing. Judicial discretion is, to some extent,
replaced by prosecutorial discretion, producing a loss of
transparency in decision-making. In California, under
the Three Strikes law, prosecutors and even judges
ignore previous convictions where they feel the
defendant deserves leniency. MMS do not appear to
promote equity in sentencing as they seem to be applied
disproportionately to low-level offenders and those from
minority groups. One reason is that high-level offenders
(e.g., drug kingpins) have more information to trade in
return for more lenient treatment. Women and
Research and Statistics Division 23
aboriginal peoples may suffer disproportionately from
the privations associated with MMS.
Furthermore, it has been argued that the imposition of
uniformity in sentencing may create other disparities as
different offenders are treated similarly. The offender’s
degree of culpability and role in the offence are ignored
when sentencing is based exclusively on the nature of
the infraction.

7.1Court Costs
A
ssessments of California’s “Three Strikes” law
indicate that the number of trials increase
dramatically as defendant's have little incentive
to plead guilty on charges for eligible offences (Harris
and Jesilow, 2000). A bipartisan committee established
by the US Congress to study the federal courts estimated
that even a five percent reduction in guilty pleas would
result in a 33 to 50 percent increase in trials (Federal
Courts Study Committee, 1990; cited in Wallace, 1993).
Carlson and Nidey (1995) studied the impact of a two-
day minimum jail sentence (along with mandatory
participation in an education program) on the
processing of domestic assault cases in an Iowa county.
They examined half of all the serious and aggravated
misdemeanor domestic abuse assault cases filed in the
county for one year immediately preceding and two
years immediately following the implementation of the
measures (June 1992). The investigators also conducted
formal interviews with four defense attorneys and one
district court judge. They found that the length of time
taken to adjudicate cases increased and that cases
became substantially more complex and time
consuming in the year immediately following the new
measures. The interviews indicated that the MMS
reduced the incentive for defendants to plead guilty,
resulting in increased workloads. Public defenders and
prosecutors had to prepare for more trials and subpoena
more witnesses, court staff had to manage the increase
in trial time, and judges had to hear more cases. This
relatively mild minimum penalty therefore added
substantially to the cost of processing cases.
Cushman (1996) reported on the expected increase in
demand on the resources of three California counties
produced by the “Three Strikes” law. These projections
were based on an exercise involving judges, prosecutors,
public defenders, probation officers, and law
enforcement officials in which 73 cases adjudicated
prior to the law were re-examined to ascertain how they
might be adjudicated under the “Three Strikes” law.
This exercise revealed that the expected increase in jury
trials in Los Angeles, Santa Clara, and San Diego
Counties was 144%, 193%, and 300%, respectively. In
Los Angeles, in absolute terms, this would mean an
additional 3,400 jury trials in one year. Furthermore,
while 94% of California felony cases were disposed of
through plea bargaining prior to the law, just 6% of
Three Strikes cases were resolved in that manner
following its implementation. Increasing jury trials
means more jurors, hearings, longer preliminary
hearings, increasing defence costs, more court security,
and a larger pre-trial jail population (Cushman, 1996).
Civil litigation, too, may be affected by an increase in
jury trials, as delays for civil litigants increase. The
greater use of incarceration brought about by Three
Strikes and related laws might have the benefit of lower
probation caseloads, although this saving would not
offset the additional court and prison costs.
The costs of implementing MMS may be offset, to some
degree at least, by their crime preventive effects (Austin,
1996), although evidence from California suggests that
the state’s Three Strikes law has not produced savings
with regard to insurance premiums, security expenses,
or victim services (Schultz, 2000). Some jurisdictions
report that the pressure on prosecutorial resources and
on local jails is such that many misdemeanour cases are
being dismissed (Cushman, 1996). Thus, a major side
effect of severe MMS is a weakening of the justice
system’s ability to deal with offences not covered by the
law in question.
7.2Effects on Prison Populations
A study using data from the six most populous US states
found that rising prison populations from 1977-88 were
strongly influenced by explicit changes in imprisonment
policies, including the introduction of MMS in these
states (Cohen and Canela-Cacho, 1994). The authors
found that both increases in the expected certainty and
length of incarceration during the period played a role in
increasing prison populations.
Wooldredge (1996) examined the relationship between
state-level sentencing policies and inmate crowding for
1991. He found that states with larger populations were
more likely to have longer minimum prison sentences
and more mandatory prison terms for felony
convictions. These MMS, in turn, result in more long-
term prison inmates. As this population ages, more
medical and other resources will be required to
accommodate this situation (Chaneles, 1987). The
unintended consequences of MMS, especially those that
are longer in duration, will become more obvious and
7.0 The Economic Impact of Mandatory
Sentences
Research and Statistics Division 25
likely more dire as time goes on and more long-term
offenders are placed in the system.
Bales and Dees (1992) note that the creation of a large
sub-population of long-term offenders as a result of
MMS may produce management problems for
institutions. This may especially be the case where MMS
preclude the acquisition of “good-time” credits by
inmates, thereby leaving little incentive for them to
conform to institutional rules. The authors further
assert that, in jurisdictions such as Florida, MMS may
have the unintended effects of accelerating the early
release of other inmates, due to court-ordered ceilings
on prison populations. The greater the number of long-
term inmates serving MMS, the shorter the sentences of
other inmates need to be in order to keep the prison
population under the ceiling. In Los Angeles County jail,
for example, inmates currently serve just 45% of their
sentence to make room for defendants awaiting trial
(Markel, 1996). Shortening the sentences or accelerating
releases of offenders not subject to MMS may, in turn,
increase public disapproval, the rationale for
introducing MMS in the first place.
California’s “Three Strikes” law has been projected to
require an additional 20 prisons in the short-term and to
cost upwards of $5 billion (Owens, 1995). Each sentence
of 25 years to life will cost the taxpayer at least half a
million dollars (Markel, 1996). The costs of such laws
accrue over time as the additional time served under
Three Strikes and similar legislation may take effect
years after the passing of sentence (Schultz, 2000). A
Texas recidivist statute, even more all-encompassing
than California's in its inclusion of minor property
offences as “strikes”, helped increase the state’s prison
building budget from $64.7 million in 1974 to $3.7 billion
in 1994. In addition, the cost of operating the state’s
prisons rose six-fold from 1982 to 1992. MMS
introduced in Oregon to be imposed for 16 felonies is
expected to require 6,085 additional prison beds in the
next five years at a cost of $461 million for construction
and more than $100 million per year for operation
(Bogan and Factor, 1995).
Vitiello (1997) argues that legislatures in states with
Three Strikes laws will be forced to allocate resources
away from prevention programs and law enforcement to
pay for prison construction and maintenance. Fewer
street officers will mean a lower certainty of
punishment. The long-term result, he conjectures, is
that resources will be expended increasingly to
incarcerate an older and less dangerous prison
population, while younger offenders will face a lower
chance of being caught. These more active offenders will
thus be on the street longer before they are
incapacitated.
MMS calling for long prison terms will carry prohibitive
costs due to sizable increases in jury trials and prison
populations. These costs may weaken the justice
system’s response to crimes and offenders not subject to
MMS, as resources are shifted from these other areas.
Lengthy MMS will yield an increasingly older prison
population, creating a perverse effect whereby prisons
will house more “costly” but, at the same time, less
dangerous inmates.
MANDATORY MINIMUM PENALTIES
26 Research and Statistics Division
T
he US Sentencing Commission (1991) favoured
sentencing guidelines over MMS for a number of
reasons. To begin with, the guidelines
incorporated the MMS as the base-level sentences in
their sentencing ranges. The Commission viewed
sentencing guidelines as more precise in giving
consideration to offence and offender characteristics.
While allowing judges to depart from guideline ranges,
these departures were rare and certainty of punishment
was quite high. On the other hand, the extent of
prosecutorial discretion in the case of MMS and the
failure to prove all the elements at trial undermine the
certainty of punishment and, hence, their potential
deterrent effect. The Commission considered MMS a
highly blunt instrument, providing low-level drug mules
the same sentences as kingpins. As far as inducing the
cooperation of defendants with the authorities, the
Commission felt that the guidelines achieved this goal
just as effectively as the provision for substantial
assistance motions in the case of MMS. The guidelines
provide for a two-level reduction in the sentence
calculation for an offender’s “acceptance of
responsibility”.
There have been many illustrations of seriously
disproportionate sentences under mandatory
sentencing laws. A 25-years to life sentence for a
shoplifter taking food valued at a few dollars, an
individual stealing a slice of pizza on the beach, and a
50-year-old man, with a record of two bicycle thefts as a
juvenile, trying to pass a bad check (a hypothetical
scenario) illustrate the actual and potential side effects
of California’s “Three Strikes” law (Owens, 1995). The
disproportionate sentences sometimes meted out under
mandatory minimum statutes resulted in the enactment
of the Violent Crime Control and Law Enforcement Act in
1994 which, among other things, exempted low-level,
first-time, nonviolent drug offenders from MMS. The
provision instructs courts to follow the sentencing
guidelines for this class of offenders, thereby tacitly
acknowledging the limitations and excesses of MMS
(Oliss, 1995).
Such safety valves are inevitable consequences of very
tough legislation. In California, the “Three Strikes” law
allows prosecutors to dismiss offenders’ prior
convictions if they believe the law mandates a seriously
disproportionate sentence (Benekos and Merlo, 1995).
The hydraulic nature of the justice system (i.e.,
discretion cannot be removed, only transferred) is also
illustrated by the ability of prosecutors to classify
borderline offences as misdemeanours rather than
felonies, thereby circumventing MMS for repeated
felonies. Some prosecutors in California have also
reported that victims have occasionally let it be known
that they would not testify if a conviction meant the
defendant would be subject to the “Three Strikes” law.
Jury nullification may also be a side effect of MMS. It
may take the form of the refusal to convict due to the
view that a penalty is excessive (Harris and Jesilow,
2000). The Romeroruling by California's Supreme Court
has added another safety valve by enabling judges to
discount previous convictions if justice is thereby
served.
Mandatory sentencing laws, such as Canada’s minimum
terms for murder and California’s “Three Strikes
initiative, have also been criticized on the grounds that
the discretion of correctional officials to reward good
behaviour is severely limited or removed (Owens, 1995).
The control of prisoners subject to such sentences is
thereby more difficult, producing a potentially more
volatile correctional population. Similar side effects
include instances in which suspects have resisted arrest
and even shot at police officers believing that, if
apprehended, they would be prosecuted under a “Three
Strikes” law (Benekos and Merlo, 1995). These
observations illustrate another hydraulic feature of such
laws; the displacement of some violence from the street
to the criminal justice system. It has been further
argued that the increasing desperation of defendants
will lead to more suicides and killings of witnesses, as
the harsh sentences leave little room for additional
consequences for such actions (Markel, 1996).
The rigidity of MMS results in some grossly
disproportionate sentences. The prospects of such
disproportionate sentences inevitably lead to
compensating behaviours that contravene the
sentencing regime. Severe MMS may increase the
danger to which police, correctional personnel, and
victims/witnesses are exposed as offenders may display
more desperation in their attempts to avoid capture or
conviction and they may have fewer incentives to
behave cooperatively while in custody.
The US Sentencing Commission favours sentencing
guidelines to MMS, as sentences are more likely to be
proportional to the offence and to take offender
characteristics and into account. Sentencing guidelines
are also likely to be administered more consistently as
they are less likely to be undermined by justice system
actors.
8.0 Other Issues
Research and Statistics Division 27
F
rom an international perspective, MMS range from
fines and license restrictions for impaired driving
to life terms and even the death penalty for murder
and drug trafficking. Such a wide range of sanctions and
triggering offences precludes sweeping generalizations
about the impact of MMS. Hence, conclusions about the
utility of MMS ought to be qualified, tailored to specific
crime categories and sanctions. The severity and
inflexibility of some mandatory sentencing policies is
such as to place a special onus on proponents to
demonstrate that their economic and human costs, as
well as their incursion upon the judicial role in
sentencing, is warranted by their preventive and other
benefits.
This review focused on the utilitarian, as opposed to the
retributive or denunciatory aims of MMS. To that end,
the manner in which MMS have been implemented was
examined to determine whether, in fact, these penalties
do increase the certainty and/or severity of penal
sanctions. A hydraulic view of the justice system
suggests that the removal of discretion at one level (e.g.,
the judicial) may merely shift it to the prosecutorial
level. Crime reduction can be expected only if MMS are
applied consistently. Even then, there is no guarantee
that they will increase the severity of sanctions, as
previous sanctions may have exceeded the statutory
minimum introduced. Similarly, MMS may fail to
increase the certainty of punishment if prosecutors
circumvent them by reducing or dismissing charges and
juries are more reluctant to convict defendants they feel
would face excessive punishment.
Where MMS are properly applied, their marginalor
added benefits over alternative sanctions must be
demonstrated. Thus, will a MMS that increases the
average prison term for an offence from seven to nine
years deter more people from committing that offence
or prevent additional crimes through incapacitation?
Incapacitation does not always prevent crime (where
offenders commit crimes in groups or are replaced in the
illicit marketplace) and is thought to provide
diminishing returns as offenders age.
9.1Deterrence and Incapacitation
Practically speaking, more lengthy MMS must be shown
to have deterrent as well as incapacitative effects in
order to justify substantial increases in prison
populations. The potential crime preventive effects of
legal sanctions vary in relation to the target population.
The evidence on deterrence suggests that the potential
offender population comprises at least two broad
groups. Society at large, including more casual
offenders, is seen as showing some rationality in the
decision to commit crimes and the form such crimes will
take. This rationality extends to an awareness of and
consideration of risk, including penal sanctions. The
second and smaller group is more enmeshed in
criminality as a career or lifestyle. Such individuals are
more antisocial, less concerned about the consequences
of their actions, and less fearful of legal sanctions,
including prison.
Deterrent and incapacitation effects may need to be
viewed from the perspective of this broad typology. Also
important are factors such as age, nature of the offence,
and the certainty, severity and celerity of sanctions. For
the broader segment of society that is likely to respond
to the threat of punishment and moral suasion, it may
be that milder, but more certain penalties would
constitute the most optimal application of sanctions.
From a utilitarian point of view, incapacitating casual or
low-rate offenders for long periods is a waste of justice
system resources, especially when these individuals may
respond to moral appeals and the mere threat of
sanctions. Conversely, incapacitation for longer periods
may be the only recourse for highly active career
criminals who tend not to respond to the threat of
sanctions or to moral appeals.
Such variation among offenders has led, over the past 25
years, to occasional calls by influential scholars for the
implementation of selective incapacitation strategies;
i.e., the neutralization of high-risk offenders based on
individual risk factors. However, such preventive
confinement is problematic, due to the many prediction
errors and undermining of the principles of
proportionality and the presumption of innocence.
Some predictors (e.g., race or employment history)
would be seriously objectionable. Chronic, serious
offenders are believed to have an elevated likelihood of
detection due to their higher levels of criminal activity
and criminal history is believed to be one of the best
predictors of recidivism. Consequently, these people
might be adequately dealt with under more traditional
(retributive) sentencing practices. Courts take the
criminal record into account in sentencing and some
mandatory sentencing provisions are triggered by a
previous conviction.
9.0 Conclusions
Research and Statistics Division 29
The present review examined the implementation and
impact of MMS, focusing on the last two decades (1980-
2000). It relied almost exclusively on American research,
due to the dearth of such evaluations in Canada.
Initiatives in the United Kingdom, Australia, and
Malaysia were also included. This review first examined
mandatory sentencing policies that encompassed a
broader category of offences. The highly publicized
“Three Strikes” law in California is an illustration, as it
applies to any felony conviction following two prior
convictions for serious crimes. MMS for impaired
driving, firearms and drug offences were then examined.
Finally, this review examined estimates of the impact of
hypothetical MMS arrived at by various statistical
models. Following the assessment of the impact of MMS
on crime, their economic impact, effects on sentencing
disparity, and related issues were discussed.
9.2General Mandatory Sentencing
Laws
The evidence was mixed with regard to the impact of
more generalized MMS of the “Three Strikes” variety.At
best, studies showed modest crime preventive effects.
While California showed a sharper decline in crime than
other states following implementation of its “Three
Strikes” law, communities in that state showed
inconsistent effects and studies comparing states with
and without such a law show no difference with regard
to crime trends. Explanations for the lack of a more
dramatic effect include the inconsistent application of
such sweeping laws, the small proportion of individuals
to whom these laws apply, and the possibility that they
provide limited marginal returns as many high-rate
offenders may already be incarcerated under existing
legislation.
9.3Mandatory Sentences for
Firearms Offences
Enhanced sentences for firearms infractions show some
promise, although findings here, too, are inconsistent or
unclear.Although a major Canadian evaluation
suggested that the introduction in 1977 of the one-year
mandatory prison term for the use of a firearm in crime
(Section 85 of the Criminal Code) was accompanied by a
modest decrease in the proportion of homicides and
robberies committed by firearms, there was some
evidence of a displacement to offences committed by
other weapons. A number of serious methodological
flaws preclude more definitive assertions about the law’s
impact. There is evidence that Section 85 has been
applied inconsistently and has failed to increase
sentence length as judges appear to provide a “going
rate” for different crimes, adjusting the sentence for the
primary offence downward to compensate for the
sentence enhancement. In several American
jurisdictions, gun homicides and/or robberies have
declined following the introduction of firearm sentence
enhancements. The evidence was mixed on the impact
of Massachusetts’ Bartley-Fox Amendment, a law
prescribing a one-year MMS for carrying a gun illegally.
Subject to a series of evaluations, this Amendment may
have failed to meet expectations due to adaptive
behaviour by the police (e.g., searches of suspects
became more selective and guns were often confiscated
without charges). Perhaps most disconcerting for
proponents of firearm sentence enhancements was a
study interviewing robbers in Western Australia. That
study revealed that the majority of robbers who had
used guns indicated they would continue to do so
despite their awareness of sentence enhancements and
concern about the consequences of repeating their
offences.
9.4Mandatory Sentences for
Impaired Driving
There are some methodological impediments to
assessing the effects of MMS on impaired driving, as
legal sanctions are often accompanied by treatment for
alcohol abuse. Further confounding evaluations in this
area is the role of educational campaigns. High-profile
publicity campaigns tend to accompany new legislative
initiatives on impaired driving, making it difficult to sort
out the relative importance of deterrent and
denunciatory effects. Research that has attempted to
isolate these effects has found that people may respond
more to the shame associated with impaired driving
than to the threat of legal sanctions. However, the level
of shame is undoubtedly influenced by the nature and
severity of sanctions and accompanying publicity
campaigns. While the evidence overall underscores the
critical role played by vigorous law enforcement and the
certainty of punishment in this area, studies provide
little reason for optimism with regard to the efficacy of
tough sanctions.While not unanimous, studies indicate
that MMS and sanctions of increasing severity do not
appear to reduce recidivism rates or alcohol-related
road accidents. One author asserts that impaired
driving is a unique offence in that alcohol consumption
and, often, abuse is inherent to it. He notes that repeat
offenders commit a disproportionate number of these
offences and do not tend to respond to punishments
(such as license revocations) due to their substance
abuse problem.

9.5Mandatory Sentences for Drug
Offences
Severe MMS seem to be least effective in relation to drug
offences.Studies using a variety of methodologies
seriously question the value of the “drug war” approach.
The draconian penalties in Malaysia are routinely
circumvented by the judiciary and the tough MMS in the
US (both at the state and federal levels) have imprisoned
mostly low-level, nonviolent offenders. Drug
consumption and drug-related crime seem to be
unaffected, in any measurable way, by severe MMS.
Both mathematical modeling techniques and field work
arrive at the conclusion that treatment-oriented
approaches are more cost effective than harsh prison
terms. Most drug dealers operate at a low-level and are
not committed to this activity in a single-minded way.
MMS are blunt instruments that provide a poor return
on taxpayers’ dollars because they fail to distinguish
between low and high-level, as well as hardcore versus
transient dealers. An optimal approach might require a
mix of accessible treatment for addicted dealers,
employment opportunities for part-time dealers, and
tough sentences for hardcore, high-level dealers.
9.6The Impact of Hypothetical
Mandatory Sentencing Policies
Studies examining the crime preventive effects of
hypothetical MMS triggered by a violent crime have
consistently found that the benefits would be modest
relative to the elevated prison costs. This is due to the
relatively low number of individuals who would
reconvicted on other violent offences during the time
these penalties would be in effect. From a utilitarian
point of view, such collective incapacitation strategies
would needlessly incarcerate many individuals not at
risk of reconviction. Selective incapacitation strategies
targeting high-rate offenders would be more efficient;
however, prediction problems abound and they are
unlikely to be implemented due to concerns that they
would undermine fundamental legal principles.
9.7Sentencing Disparity
There is no evidence that either discretion or disparities
are reduced by MMS. While judicial discretion in the
sentencing process is reduced (not removed),
prosecutors play a more pivotal role as their charging
decisions become critical. The shift in influence over
sentencing from the judicial to the prosecutorial level
also represents a loss of transparency in decision-
making, as prosecutorial decisions are less open to
scrutiny than those made by judges. In California, under
the Three Strikes law, prosecutors have been
inconsistent in their application of the law from case to
case and across jurisdictions. They often ignore
“strikes” if they feel that a case deserves leniency. In the
US federal system, the only statutory exemptions to
MMS apply when defendants have been shown to
provide “substantial assistance” in the prosecution of
other cases. High-level offenders are more likely to
provide useful information and therefore are usually the
beneficiaries of such discounts. This situation also
undermines the rationale for mandatory sentencing
policies in many jurisdictions – targeting drug kingpins
and violent offenders.
In California, trial judges have dismissed previous
“strikes”, arguing that the MMS would have constituted
“cruel and unusual” punishment, in violation of the
state’s constitution. The state’s Supreme Court upheld
the right of judges to overlook previous convictions on
the grounds that the dismissal of cases is a judicial
rather than an executive function. Such rulings
affirming the separation of powers between the judicial
and executive branches, and the right of judges to
dismiss prior convictions in the interests of justice may
be inevitable consequences of draconian mandatory
sentencing policies. Furthermore, racial disparities in
sentencing have been exacerbated by MMS in the US,
both at the federal and state levels. Taken together,
therefore, prosecutorial and judicial practices, inter-
jurisdictional differences in these practices, advantages
to high-level offenders, and racial disparities indicate
that MMS do not necessarily provide for more equitable,
consistent, or predictable sentencing.
It has also been argued that the uniformity in sentencing
ostensibly imposed under MMS may create other
disparities as different offenders are treated similarly.
By focusing exclusively on the nature of the infraction,
the offender’s degree of culpability and role in the crime
is ignored. Women, for example, may be pressured into
participating in crimes by abusive partners. Also,
gender neutral sentencing may place a special burden
on women due to their familial responsibilities and the
dearth of programs in correctional facilities for women.
Disparities may be exacerbated by MMS in another way.
To the extent that sentences under mandatory
sentencing policies are more severe, the gap may
increase between cases in which charges are bargained
down and those that receive a lengthy MMS.
Research and Statistics Division 31
9.8Some Adverse Effects of
Mandatory Sentences
MMS calling for lengthy prison terms are likely to carry
massive costs.Jury trials increase dramatically, as
defendants usually have little incentive to plead guilty.
More defence counsel, prosecutorial, and judicial
resources, as well as court staff, are required. The pre-
trial jail population is likely to increase. Massive
increases in prison construction and operating costs
have been observed and projected. In some
jurisdictions, these increases have led to the early
releases of those not subject to MMS, thereby weakening
the justice system's response to other crimes. Lengthy
MMS will also create a progressively older prison
population, with its accompanying costs.
MMS, such as the Three Strikes and federal drug laws in
the US, have produced some grossly disproportionate
sentences.When laws are judged by a broad array of
justice system actors and by the public to be excessively
harsh, compensating behaviours inevitably arise. The
experience in California with the Three Strikes law
suggests that instances in which the law is circumvented
by prosecutors and even judges are numerous. Such
laws may also lead to more desperate actions among
fugitives seeking to avoid these harsh sentences.
Shootouts with the police and attacks/threats against
witnesses may increase with such laws. Correctional
facilities, too, may be more difficult to manage where
MMS remove incentives for cooperative behaviour by
removing credits for good behaviour.
9.9Concluding Remarks
There is a conspicuous absence of Canadian research on
MMS, given the number of infractions carrying such
penalties and the number of private members’ bills, in
the last two years, seeking to introduce MMS. Especially
noteworthy is the lack of any systematic evaluation of
the ten, four-year MMS for certain offences involving a
firearm introduced with the enactment of Bill C-68 in
1995. Also noteworthy is the absence of evaluations of
mandatory sentencing provisions relating to impaired
driving.
The evaluation of these and other mandatory sentencing
provisions ought to examine their implementation,
effects on sentencing patterns, and crime rates, as well
as their fiscal costs. The level of public awareness of
these penalties also must be ascertained, as such
awareness is a precondition of deterrent and
denunciatory effects.
Long-term projections of the fiscal costs and crime
preventive benefits of MMS are complex undertakings
involving many assumptions. It is critical to distinguish
between the lengthy minimum prison terms required by
laws such as “Three Strikes” and the more modest
penalties for offences such as impaired driving, as the
challenges posed by the former are considerably more
daunting. Mandatory life sentences triggered by a third
offence, with little regard for the nature of that offence,
clearly have many pitfalls (see previous section). The
use of MMS as instruments in the “War on Drugs” also
has many limitations, especially when they are triggered
by drug quantity alone. Offender motivation and
substance abuse, as well as their position in criminal
enterprises, ought to be considered if proportional and
effective sentences are to be imposed.
MMS show somewhat more promise with regard to
impaired driving and firearms offences. Mandatory
fines and licence restrictions may create more
predictable consequences to which the casual impaired
driver may respond. These offenders seem to respond to
measures increasing the certainty of punishment, as
well as accompanying publicity campaigns that may
increase the level of shame associated with this
behaviour. On the other hand, repeat offenders with
substance abuse problems appear to be less responsive
to these measures.
Firearms infractions, too, have responded to MMS in
some contexts. In Canada, most of the MMS for firearms
offences apply to their unlawful use during the
commission of a criminal offence. These provisions are
thus meant as an add-on or enhanced sentence to that
imposed on the primary offence. One major concern is
that the courts do not treat these mandatory minima as
add-ons but, rather, tend to impose an overall sentence
that may not exceed that imposed for the same offence
prior to the introduction of the mandatory penalty.
Another concern is whether these MMS will serve as a
marginal deterrent in relation to those prepared to
commit the primary offence. Thus, if an individual is
prepared to commit a robbery – a crime carrying a
maximum sentence of imprisonment for life – will he
now be deterred by a four-year minimum penalty,
assuming that it is usually imposed? Even if he is
deterred from using a gun (a questionable assumption
given some Australian research), he may substitute
another weapon in the commission of the same offence.
A critical issue with regard to the potential deterrent and
incapacitative effects of MMS is the pool of offenders to
whom these penalties apply. More persistent and active
offenders are generally more difficult to deter with the
threat of sanctions or to influence through moral
MANDATORY MINIMUM PENALTIES

appeals. Deterrence will therefore be more in evidence
in relation to those offences usually committed by more
casual or opportunistic offenders. Incapacitative
effects, on the other hand, will be more pronounced in
relation to those crimes most often committed by highly
active offenders. From a utilitarian point of view,
incarcerating occasional, non-violent offenders, for
substantial periods, constitutes a colossal waste of
justice system resources.
The marginal benefits of incapacitation are also
dependent on the number of highly active offenders still
at liberty when MMS are introduced; that is, the extent
to which the existing sentencing regime was successful
in neutralizing these offenders. Incapacitative effects
also diminish with age, while the costs of custodial
sentences increase as offenders get older. The use of
incarceration as a preventive measure, therefore, must
be finely tuned or its counterproductive effects may well
outweigh its benefits. Therefore, MMS should not be
introduced merely to placate a political constituency or
without regard to a thorough understanding of the
infractions or offenders for whom they are intended.
