The 18 U.S.C. 924(c) Tack-On in Cases Involving Drugs or Violence

Summary
Section 924(c) requires the imposition of one of a series of mandatory minimum terms of
imprisonment upon conviction for misconduct involving the firearm and the commission of a
federal crime of violence or a federal drug trafficking offense. The terms vary according to the
type of firearm used, the manner of the firearm’s involvement, and whether the conviction
involves a single, first-time offense. Liability extends to co-conspirators and to those who aid or
abet in the commission of a violation of the section.
If a machine gun, silencer, short barreled rifle, short barreled shotgun, or body armor is involved,
the offense is punished more severely. If the firearm is brandished or discharged, the offense is
punished more severely. Repeat offenders are likewise punished more severely. Twenty-five-year
mandatory minimum terms for multiple offenses must be served consecutively. The mandatory
minimum terms range from imprisonment for five years to imprisonment for life; consecutive
mandatory minimum terms may exceed 100 years. In each case the maximum term is life
imprisonment.
The United States Sentencing Commission has suggested that Congress consider amending
Section 924(c) to (1) address the “stacking” of 25-year charges for multiple offenses; (2) require a
prior conviction to trigger repeat offender enhancements; (3) provide sentencing courts with
discretion over whether to impose concurrent or consecutive sentences; and (4) clarify the
statutory definitions of the terms used in Section 924(c).
Section 924(c) has withstood constitutional challenges based on the Second Amendment’s right to
bear arms; the Eighth Amendment’s cruel and unusual punishments prohibition; the Sixth
Amendment’s right to jury trial; the Fifth Amendment’s double jeopardy proscription; and the
Constitution’s structural limitations on preservation of the separation of powers and on
Congress’s authority under the Commerce Clause.

The 18 U.S.C. 924(c) Tack-On in Cases Involving Drugs or Violence

Introduction
Mandatory minimums are found in two federal firearms statutes. One, the Armed Career Criminal
Act, deals exclusively with recidivists.1 The other, Section 924(c), attaches one of several
mandatory minimum terms of imprisonment whenever a firearm is used or possessed during and
in relation to a federal crime of violence or drug trafficking.2 Section 924(c) has been the subject
of repeated Supreme Court litigation3 and regular congressional amendment since its inception in
1968.4
Section 924(c), in its current form, imposes one of several different minimum sentences when a
firearm is used or possessed in furtherance of another federal crime of violence or of drug
trafficking. The mandatory minimums, imposed in addition to the sentence imposed for the
underlying crime of violence or drug trafficking, vary depending upon the circumstances:
• imprisonment for not less than five years, unless one of higher mandatory
minimums below applies;
• imprisonment for not less than seven years, if a firearm is brandished;
• imprisonment for not less than 10 years, if a firearm is discharged;
• imprisonment for not less than 10 years, if a firearm is a short-barreled rifle or
shotgun or is a semi-automatic weapon;
• imprisonment for not less than 15 years, if the offense involves the armor
piercing ammunition;
• imprisonment for not less than 25 years, if the offender has a prior conviction for
violation of Section 924(c);
• imprisonment for not less than 30 years, if the firearm is a machine gun or
destructive device or is equipped with a silencer; and
• imprisonment for life, if the offender has a prior conviction for violation of
Section 924(c) and if the firearm is a machine gun or destructive device or is
equipped with a silencer.5

The 18 U.S.C. 924(c) Tack-On in Cases Involving Drugs or Violence

The mandatory minimum sentences were added to Section 924 as a floor amendment to the Gun
Control Act of 1968.6 The amendment, as introduced, called for a 10-year minimum of
imprisonment to be imposed when a firearm was used in the commission of various state and
federal crimes of violence.7 A substitute amendment reduced the minimums from 10 years to one
year for a first offense, and from 25 years to five years of subsequent offenses.8 It limited its
application to federal felonies, but also barred a sentencing court from imposing the sanction as a
concurrent sentence, from suspending the sentence, or from imposing a probationary sentence.9
The impact was somewhat mitigated by a 1971 amendment which reduced the minimum for
second and subsequent offenses from five years to two years.10 Moreover, until the Sentencing
Reform Act of 1984 eliminated parole, a federal offender was eligible for parole after serving the
lesser of one-third of his sentence or 10 years.11
The Sentencing Reform Act also rewrote Section 924(c) limiting its application to firearms-
related federal crimes of violence, but changing its mandatory minimums to a flat five-year term
of imprisonment for first offenders and a flat 10-year term for a second or subsequent
conviction.12
Section 104 of the Firearms Owners Protection Act expanded the predicate offenses to include
drug trafficking as well as crimes of violence and added a flat 10-year minimum for cases
involving machine guns or silencers (a flat 20-years for a second or subsequent offense)13—which
two years later Congress increased to flat sentences of 30 years and life imprisonment,
respectively.14 Congress added the shot-barreled firearms and destructive device provisions in
1990.15
Originally, Section 924(c) condemned only “use” of a firearm in connection with certain federal
offenses.16 Then the Supreme Court pointed out in Bailey that the word “use” demands more than
simple possession.17 Congress amended the section in 1998 to outlaw not only use during and in

established a 25-year minimum for second and subsequent offenses, Id.

9 Id. Further modifications were offered during the course of the debate, but the language enacted was in large measure
that of the Poff substitute, see 114 Cong. Rec. 22229-22248 (1968); H.Rept. 90-1956, at 12, 31-32 (1968)(confining the

factor in relation to the predicate offense.... ‘[U]se’ must connote more than mere possession of a firearm by a person
who commits a drug offense”).

relation to a predicate offense, but possession “in furtherance” of a predicate drug trafficking or
violent offense as well.18
Elements, Components, and Other Factors
Firearm
A “firearm” for purposes of Section 924(c) includes not only guns (“weapons ... which will or
[are] designed to or may readily be converted to expel a projectile by the action of an explosive”),
but silencers and explosives as well.19 It includes firearms that are not loaded or are broken;20 it
does not, however, include toys or imitations.21
Predicate Offenses
The drug trafficking predicates include any felony violation of the Controlled Substances Act, the
Controlled Substances Import and Export Act, or the Maritime Drug Law Enforcement Act.22 The
crime of violence predicates are statutorily defined as any federal felony that satisfies either of
two tests, that is, (1) if it “has as an element the use, attempted use, or threatened use of physical
force against the person or property of another,” or (2) if it “by its nature, involves a substantial
risk that physical force against the person or property of another may be used in the course of
committing the offense.”23
The Supreme Court has addressed several other aspects of Section 924(c), but it has yet to decide
what constitutes a crime of violence for purposes of the section. In Leocal v. Ashcroft, however, it
had occasion to examine the question under 18 U.S.C. 16 which defines crimes of violence in
virtually the same terms.24

or firearm silencer; or (D) any destructive device.... (4) The term ‘destructive device’ means - (A) any explosive,
incendiary, or poison gas - (i) bomb, (ii) grenade, (iii) rocket having a propellant charge of more than four ounces, (iv)
missile having an explosive or incendiary charge of more than one-quarter ounce, (v) mine, or (vi) device similar to any

element the use, attempted use, or threatened use of physical force against the person or property of another, or (b) any
other offense that is a felony and that, by its nature, involves a substantial risk that physical force against the person or
property of another may be used in the course of committing the offense.”

The 18 U.S.C. 924(c) Tack-On in Cases Involving Drugs or Violence

There, it reasoned that the wording of the definition precluded its application to the crime of
driving under the influence and causing injury. When the statute speaks of the element involving
the “use ... of physical force against the person or property of another”—as both Sections 16 and
924(c)(3) do—it means “a higher degree of intent than negligent or merely accidental conduct.”25
When, like Sections 16 and 924(c)(3), it speaks of a “risk that physical force against the person or
property of another may be used in the course of committing the offense,” it means the “risk that
the use of physical force against another might be required in committing the offense,” not the
risk that physical force might inadvertently or negligently be visited upon another.26 “The
ordinary meaning of this term [(the use of physical force)] ... ‘calls to mind a tradition of crimes
that involve the possibility of more closely related, active violence’”).27
The circuit courts have found a wide range of federal crimes fit the definition.28 One has used the
Leocal tests to reconcile the conflicting views in other circuits and decide that firearm possession
offenses are not crimes of violence for purposes of Section 924(c).29

risk that the use of physical force against another might be required in committing a crime.... The ordinary meaning of
this term ... ‘calls to mind a tradition of crimes that involve the possibility of more closely related, active violence’”).

The 18 U.S.C. 924(c) Tack-On in Cases Involving Drugs or Violence

Possession in Furtherance
The possession prong of the offense requires that the defendant “(1) knowingly, (2) possessed a
firearm, (3) in furtherance of any [federal] drug trafficking crime.”30 The “in furtherance” element
compels the government to show some nexus between possession of a firearm and a predicate
offense, that is, to show that the firearm furthered, advanced, moved forward, promoted, or in
some way facilitated the predicate offense.31 This requires more than proof of the presence of a
firearm in the same location as the predicate offense.32 Most circuits have identified specific
factors that commonly allow a court to distinguish guilty possession from innocent “possession at
the scene,” particularly in a drug case, that is, “(1) type of drug activity [or violent crime] that is
being conducted, (2) accessibility of the firearm, (3) the type of the weapon, (4) whether the
possession is illegal, (5) whether the gun is loaded, (6) the proximity to the drugs or drug profits,
and (7) the time and circumstances under which the gun is found.”33
Although the Supreme Court has made it clear that acquiring a firearm in an illegal drug
transaction does not constitute “use” in violation of Section 924(c),34 several of the circuits have
found that such acquisition may constitute “possession in furtherance.”35
Use or Carry
The “use” outlawed in the use or carriage branch of Section 924(c) requires that a firearm be
actively employed during and in relation to a predicate offense, that is, either a crime of violence

using or carrying a firearm (2) during and in relation to (3) any federal crime of violence.... We need not decide
whether some form of scienter is also a required element because it would not affect our analysis”).

or a drug trafficking offense.36 A defendant “uses” a firearm during or in relation to a drug
trafficking offense when he uses it to acquire drugs in a drug deal,37 or when he uses it as
collateral in a drug deal,38 but not when he accepts a firearm in exchange for drugs in a drug
deal.39 The “carry[ing]” that the section outlaws encompasses instances when a firearm is carried
on the defendant’s person as well as when it is simply readily accessible in vehicle during and in
relation to a predicate offense.40
A firearm is used or carried “during or in relation” to a predicate offense when it has “some
purpose or effect with respect” to the predicate offense; “its presence or involvement cannot be
the result of accident or coincidence.”41 The government must show that the availability of the
firearm played an integral role in the predicate offense.42
Discharge and Brandish
The basic five-year mandatory minimum penalty for using, carrying, or possessing a firearm in
the course of a predicate offense becomes a seven-year mandatory minimum if a firearm was
brandished during the course of the offense and becomes a 10-year mandatory minimum if a
firearm was discharged during the course of the offense.43 The discharge provision applies even if
the firearm is discharged inadvertently.44 Whether a firearm is discharged or brandished is a
question that after Alleyne must be presented to the jury and proven beyond a reasonable doubt.45
A firearm is brandished for these purposes when (1) it is displayed or its presence made known
(2) in order to intimidate another.46 Intimidation is a necessary feature of brandishing, but it is no
less present when the fear is induced by using the gun as a club rather than merely displaying it.47

The 18 U.S.C. 924(c) Tack-On in Cases Involving Drugs or Violence

Short Barrels, Semiautomatics, Machine Guns, and Bombs
For some time, Section 924(c) consisted of a single long paragraph. When Congress added the
“possession in furtherance” language, it parsed the section. Now, the general, brandish, and
discharge mandatory penalties provisions appear in one part.48 The provisions for offenses
involving a short-barreled rifle or shotgun, a semiautomatic assault weapon, a silencer, a
machinegun, or explosives appear in a second part.49 The provisions for second and consequent
convictions appear in a third part.50
The circuits are apparently divided over the question of whether the government must show that
the defendant knew that the firearm at issue was of a particular type (i.e., short-barreled rifle or
shotgun, machine gun, or bomb).51
Prior to the division, the Supreme Court had identified as an element of a separate offense (rather
than a sentencing factor) the question of whether a machinegun was the firearm used during and
in relation to a predicate offense.52 Thereafter, it concluded that the division was a matter of style
rather than substance. Thus, the answer remains the same—use of a short-barreled rifle,
semiautomatic assault weapon, silencer, machine gun, or bomb is not a sentencing factor, but an
element of a separate offense to be charged and proved to the jury beyond a reasonable doubt.53
The question of whether a second or subsequent conviction has occurred, however, remains a
sentencing factor.54

The 18 U.S.C. 924(c) Tack-On in Cases Involving Drugs or Violence

Other Sentencing Considerations
The penalties under Section 924(c) were once flat sentences, for example, the penalty for use of a
firearm during the course of a predicate offense was a five-year term of imprisonment.55 Now,
they are simply mandatory minimums, each carrying an unspecified maximum term of life
imprisonment.56
A court may not avoid the mandatory minimums called for in Section 924(c)(1) by imposing a
probationary sentence,57 or by ordering that a 924(c)(1) minimum mandatory sentence be served
concurrently with some other sentence.58 Nor may a court mute the impact of a mandatory
minimum sentence by artificially reducing the sentence for the predicate offense.59
If a criminal episode involves more than one predicate offense, more than one violation of
Section 924(c) may be punished.60 Moreover, the second or subsequent convictions which trigger
enhanced mandatory minimum penalties need not be the product of separate trials, but may be
part of the same verdict. Thus, a defendant charged and convicted in a single trial on several
counts may be subject to multiple, consecutive, mandatory minimum terms of imprisonment.61

The 18 U.S.C. 924(c) Tack-On in Cases Involving Drugs or Violence

A number of defendants have sought refuge in the clause of Section 924(c) which introduces the
section’s mandatory minimum penalties with an exception: “[e]xcept to the extent that a greater
minimum sentence is otherwise provided by this subsection or by any other provision of law.”
Defendants at one time argued that the mandatory minimums of Section 924(c) become
inapplicable, if they are subject to a higher mandatory minimum under the predicate drug
trafficking offense under the Armed Career Criminal Act (18 U.S.C. 924(e)), or some other
provision of law.62 The Supreme Court rejected the argument in Abbott.63 The clause means that
the standard five-year minimum applies except in cases where the facts trigger one of Section
924(c)’s higher minimums.64
Section 924(c) and the Sentencing Guidelines
The mandatory minimums of Section 924(c) each carry a maximum of life imprisonment. A
defendant’s sentencing between the minimum and maximum is a matter that begins with the
Sentencing Guidelines. The Sentencing Guidelines were once binding on federal district courts.65
They are now advisory, but remain the starting point for all federal sentencing.66 Section 2K2.4 of
the Guidelines declares that unless the defendant qualifies as a career offender, the sentence for a
violation of Section 924(c) shall be the minimum called for there. The offense level adjustments
in chapter 3 (victim vulnerability, role in the offense, abuse of trust/use of special skill, multiple
counts, acceptable of responsibility) do not apply in such cases.67
In the case of career offenders, Section 4B1.1(c) of the Guidelines supplies the operable
provisions.68 A career offender for these purposes is a defendant who has at least two prior state
or federal felony convictions for a crime of violence or a drug trafficking offense.69 The Guideline
sentence for a career offender convicted of violating Section 924(c) varies according to whether
he is convicted of Section 924(c) alone and whether the court awards an acceptance of
responsibility reduction (the adjustment under chapter 3 are otherwise inapplicable).
A career offender convicted of 924(c) alone is subject to a sentencing range of either: (1) 262-327
(months)(if given a 3 level responsibility reduction); (2) 292-365 (months) (if given a 2 level
responsibility reduction); or (3) 360 (months)-life) (if given no responsibility reduction).70 If the
defendant is convicted of other offenses in addition to Section 924(c), his Guidelines sentence is

the greater of (1) the Guideline sentence for those offenses with the 924(c) mandatory minimum
tacked on, or (2) the Guideline sentence for a violation of 924(c) alone.71
The Guidelines themselves supply an example of how this last situation might play out:
The defendant is convicted of one count of violating 18 U.S.C. § 924(c) for possessing a
firearm in furtherance of a drug trafficking offense (5 year mandatory minimum), and one
count of violating 21 U.S.C. § 841(b)(1)(B) [(e.g., trafficking in 5-50 grams of crack
cocaine)] (5 year mandatory minimum, 40 year statutory maximum). Applying subsection
(c)(2)(A), the court determines that the drug count (without regard to the 18 U.S.C. § 924(c)
count) qualifies the defendant as a career offender under §4B1.1(a). Under §4B1.1(a), the
otherwise applicable guideline range for the drug count is 188-235 months (using offense
level 34 (because the statutory maximum for the drug count is 40 years), minus 3 levels for
acceptance of responsibility, and criminal history category VI). The court adds 60 months
(the minimum required by 18 U.S.C. § 924(c)) to the minimum and the maximum of that
range, resulting in a guideline range of 248-295 months. Applying subsection (c)(2)(B) [(the
Guideline sentence for conviction of §924(c) alone)], the court then determines the career
offender guideline range from the table in subsection (c)(3) is 262-327 months. The range
with the greatest minimum, 262-327 months, is used to impose the sentence in accordance
with §5G1.2(e). U.S.S.G. §4B1.1, cmt, app. n.3(E).
After the court has determined the sentencing range under the Guidelines, it determines the
defendant’s sentence, taking into account the results of the Guidelines’ calculation and the other
factors referred to 18 U.S.C. 3553(a).72
Armor Piercing Ammunition
Section 924(c) has a separate provision which outlaws predicate crime-related use, carriage, or
possession of armor piercing ammunition.73 The provision, added in 2005, greatly resembles a

the need for the sentence imposed - (A) to reflect the seriousness of the offense, to promote respect for the law, and to
provide just punishment for the offense; (B) to afford adequate deterrence to criminal conduct; (C) to protect the public

medical care, or other correctional treatment in the most effective manner; (3) the kinds of sentences available; (4) the

The 18 U.S.C. 924(c) Tack-On in Cases Involving Drugs or Violence

pre-existing provision in 18 U.S.C. 929.74 There are two significant differences. Section 924(c)(5)
carries a 15-year mandatory minimum with special provisions if a death results from the
commission of the offense. Section 929 carries a five-year mandatory minimum with no mention
of death-resulting offenses. Yet Section 929 specifically excludes the possibility of probation or
concurrent sentencing, while Section 924(c)(5) makes no mention of either. Neither provision
appears to have been prosecuted with any regularity.
Aiding, Abetting, and Conspiracy
As a general rule, conspirators are liable for any foreseeable crimes committed by any of their co-
conspirators in furtherance of the conspiracy.75 The rule applies when a defendant’s co-
conspirator has committed a violation of Section 924(c).76
Under federal law, moreover, anyone who commands, counsels, aids, or abets the commission of
a federal offense by another is punishable as though he had committed the crime himself, 18

crime.”78
Sentencing Commission Recommendations
The Sentencing Commission’s report on mandatory minimum sentences suggested several
adjustments in Section 924(c):
i. Amend the length of section 924(c) penalties
Congress should consider amending the mandatory minimum penalties established at section
924(c), particularly the penalties for “second or subsequent” violations of the statute, to
lesser terms. Section 924(c), for example, requires a 25-year mandatory minimum penalty for
offenders convicted of a “second or subsequent” violation of the statute. Reducing the length
of the mandatory minimum penalty would reduce the risk of excessive severity, permit the
guidelines to better account for the variety of mitigating and aggravating factors that may be
present in the particular case, and mitigate the inconsistencies in application produced by the
severity of the existing mandatory minimum penalties.
ii. Make section 924(c) a “true” recidivist statute
Congress should consider amending section 924(c) so that the increased mandatory
minimum penalties for a “second or subsequent” offense apply only to prior convictions. In
those circumstances, the mandatory minimum penalties for multiple violations of section
924(c) charged in the same indictment would continue to apply consecutively, but would
require significantly shorter sentences for offenders who do not have a prior conviction under
section 924(c). This would reduce the potential for overly severe sentences for offenders who
have not previously been convicted of an offense under section 924(c), and ameliorate some
of the demographic impacts resulting from stacking.
iii. Give discretion to impose concurrent sentences for multiple section 924(c) violations
Congress should consider amending section 924(c) to give the sentencing court limited
discretion to impose sentences for multiple violations of section 924(c) concurrently.
Congress has recently used this approach in enacting the offense of aggravated identity theft
and the accompanying mandatory penalty at 18 U.S.C. § 1028A. This limited discretion
would provide the flexibility to impose sentences that appropriately reflect the gravity of the
offense and reduce the risk that an offender will receive an excessively severe punishment.

iv. Amend statutory definitions
Congress should consider clarifying the statutory definitions of the underlying and predicate
offenses that trigger mandatory minimum penalties under section 924(c) and the Armed
Career Criminal Act to reduce the risk of inconsistent application and the litigation that those
definitions have fostered. To further reduce the risk of inconsistent application, Congress
also should consider more finely tailoring the definitions of the predicate offenses that
trigger the Armed Career Criminal Act’s mandatory minimum penalty.79
Constitutional Considerations
Defendants have challenged the constitutionality of Section 924(c) and its application on a
number of grounds including contentions that (1) the section is inconsistent with the Second
Amendments right to bear arms; (2) the sentence imposed constituted a cruel and unusual
punishment in violation of the Eighth Amendment; (3) the procedure used to implement its
provisions was contrary to the Sixth Amendment right to trial by jury, and to the Fifth
Amendment right to grand jury indictment; (4) imposition of the sanctions violated the
prohibition against double jeopardy; (5) Congress lacked the legislative authority to enact the
section; and (6) mandatory minimums intrude upon the judicial authority of federal judges in a
manner contrary to the separation powers.
Second Amendment
A well regulated Militia, being necessary to the security of a free State, the right of the
people to keep and bear Arms, shall not be infringed.80
The Supreme Court has explained that the Second Amendment confers an individual right to
possess and carry weapons for the defense of his or her person, family, and home.81 The Court has
been quick to point out, however, that the right is not absolute. Without providing a full panoply
of exceptions, it observed that the amendment permits such things as “longstanding prohibitions
on the possession of firearms by felons and the mentally ill, [and] laws forbidding the carrying of
firearms in sensitive places such as schools and government buildings, [and] laws imposing
conditions and qualifications on the commercial sale of arms.”82 Consistent with this theme, the
circuit courts have held that the Second Amendment cast no constitutional doubt upon Section
924(c).83

Cruel and Unusual Punishment
The Eighth Amendment provides in its entirety that “[e]xcessive bail shall not be required, nor
excessive fines imposed, nor cruel and unusual punishments inflicted,” U.S. Const. Amend. VIII.
Until very recently, there has been little consensus on the Supreme Court regarding the most
appropriate test to determine whether punishment in a noncapital case is cruel and unusual. That
seems to have changed with Graham v. Florida,84 when a majority of the court referred to one test
for “length of term-of-years” cases and another for “categorical cases.”
Contemporary Eighth Amendment jurisprudence begins with Furman v. Georgia.85 There, a
divided Supreme Court held that the Eighth Amendment, applicable to the states through the
Fourteenth Amendment, precluded imposition of the death penalty under the procedures then
common in most jurisdictions.86 Thereafter, the Court’s treatment of Eighth Amendment questions
followed two paths—one for capital punishment cases and another for imprisonment cases. In the
first of the imprisonment cases, Rummel v. Estelle, the Court rejected an Eighth Amendment
challenge from a prisoner who had been sentenced under a state repeat offender statute to life
imprisonment for the fraudulent use of the credit card.87 Yet three years later in Solem v. Helm, the
Court found contrary to Eighth Amendment proscriptions a state repeat offender statute which
carried a mandatory term of life imprisonment.88 The Court considered Helm’s punishment far
more severe than Rummel’s, because Helm was ineligible for parole while Rummel would have
been eligible in 12 years.89
The Court in Solem identified three factors to be considered in the Eighth Amendment assessment
of punishment in a noncapital case: “(i) the gravity of the offense and the harshness of the
penalty; (ii) the sentences imposed on the criminals in the same jurisdiction [for other crimes];
and (iii) the sentences imposed for commission of the same crime in other jurisdictions.”90
Then in Harmelin v. Michigan, a splintered Court rejected the Eighth Amendment challenge of a
first time offender who had been sentenced to life imprisonment without parole following
conviction on serious drug charges.91 Two distinct theories converged to form the judgment of the
Court. Two members of the Court, Justice Scalia and Chief Justice Rehnquist, rejected Harmelin’s
argument that his sentence was disproportionate to his crime because they saw no proportionality
requirement in the Eighth Amendment noncapital cases.92 Three others, Justices Kennedy,

O’Connor, and Souter, found the gravity of Harmelin’s offense sufficient to satisfy the first factor
of the Solem test and to dispense with the need to consider the other factors.93
The Court remained divided when it took up the next Eighth Amendment challenge to recidivist
sentencing in Ewing v. California.94 Three members of the Court, Chief Justice Rehnquist and
Justices Kennedy and O’Connor, concluded that a sentence of imprisonment of from 25 years to
life for a three-time offender convicted of theft was not unconstitutionally disproportionate.95 Two
others, Justices Scalia and Thomas, concurred in the judgment because neither believed that the
Eighth Amendment proscribes disproportionate sentences.96
Proportionality is balance: the severity of the punishment weighted against gravity of the offense.
Justice O’Connor’s Ewing opinion indicates that certain of a defendant’s individual
circumstances, his criminal record for instance, enhance gravity of the offense. Other cases hold
out the possibility that other individualistic circumstances, such as the defendant’s mental
capacity or maturity, may enhance the severity of the punishment. These cases also have their
origin in the death penalty cases.
The first of these, Atkins v. Virginia, held that the Eighth Amendment barred execution of a
mentally retarded defendant.97 In the years leading up to Atkins, a substantial number of state
legislatures in capital punishment states had banned execution of the mentally retarded.98
Elsewhere, though permitted in law, the practice has been abandoned in fact.99 This, coupled with
the fact that a want of defendant capacity undermines the normal expectations and justifications
of the criminal justice system, marked execution of the mentally retarded as an Eighth
Amendment impermissible excessive punishment.100
For much the same reason, the Court shortly thereafter in Roper v. Simmons declared that the
Eighth Amendment prohibited imposing the death penalty for a crime committed as a juvenile.101
Next, the Court carried the Atkins-Roper line of cases beyond the capital punishment realm. In
Graham v. Florida, Justice Kennedy explained that “[t]he Court’s cases addressing the
proportionality of sentences fall within two general classifications. The first involves challenges
to the length of term-of-years sentences given all the circumstances of a particular case. The
second comprises cases in which the Court implements the proportionality standard by certain
categorical restrictions on the death penalty.”102 In the first line of cases, the Solem-Harmelin-
Ewing
line, the Court employs a proportionality standard, and “it has been difficult for the
challenger to establish a lack of proportionality.”103

The 18 U.S.C. 924(c) Tack-On in Cases Involving Drugs or Violence

In the second line of cases, the Atkins-Roper line, Graham recognized a two-step approach used
when the challenge is based on a characteristic of the defendant, such as his mental capacity as in
Atkins or his age as in Roper.104 First, the Court “considers ‘objective indicia of society’s
standards, as expressed in legislative enactments and state practice’ to determine whether there is
a national consensus against the sentencing practice at issue.”105 Second, “guided by ‘the
standards elaborated by controlling precedents and by the Court’s own understanding and
interpretation of the Eighth Amendment’s text, history, meaning, and purpose,’ the Court must
determine in the exercise of its own independent judgment whether the punishment in question
violates the Constitution.”106
Graham challenged his sentence of life imprisonment without the possibility of parole imposed
for the commission of a nonhomicide, armed robbery, committed while a child. Using this Atkins-
Roper
approach, the Court concluded that the Eighth Amendment precluded Graham’s sentence.
It carried that logic forward in Miller v. Alabama.107 The Miller defendants had been convicted of
capital murder committed while juveniles and had been sentenced to life imprisonment without
the possibility of parole.108 That the Eighth Amendment does not permit, the Court held.109 The
Miller sentencing procedures suffered from two previously identified constitutional defects. First,
they barred consideration of the mitigating impact of the defendant’s age:
By removing youth from the balance—by subjecting a juvenile to the same life-without-
parole sentence applicable to an adult—these laws prohibit a sentencing authority from
assessing whether the law’s harshest term of imprisonment proportionately punishes a
juvenile offender. That contravenes Graham’s (also Roper’s) foundational principle: that
imposition of a State’s most severe penalties on juvenile offenders cannot proceed as though
they were not children.110
Second, the procedure not only failed to account for a paramount culpability-reducing factor, but
it also failed to account for the severity of the sentence when imposed upon a child:
Graham makes plain these mandatory schemes’ defects in another way: by likening life-
without-parole sentences imposed on juveniles to the death penalty itself. Life-without-
parole terms, the Court wrote, share some characteristics with death sentences that are shared
by no other sentences. Imprisoning an offender until he dies alters the remainder of his life
by a forfeiture that is irrevocable. And this lengthiest possible incarceration is an especially
harsh punishment for a juvenile because he will almost inevitably serve more years and a
greater percentage of his life in prison than an adult offender. The penalty when imposed on
a teenager, as compared with an older person, is therefore the same in name only. All of that
suggested a distinctive set of legal rules: In part because we viewed this ultimate penalty for
juveniles as akin to the death penalty, we treated it similarly to that most severe
punishment.111

Thus, under the current state of the law, the Eighth Amendment bars imposition of a mandatory
life term of imprisonment upon juveniles and most likely a particular term of imprisonment in
those exceptionally rare cases when the punishment is grossly disproportionate to the offense.
Given the seriousness of Section 924(c) offenses, it is perhaps not surprising that the courts have
rejected Eighth Amendment challenges even in the face of severe sentences.112
Juries, Grand Juries, and Due Process
The Constitution demands that no person “be held to answer for a capital or otherwise infamous
crime, unless on a presentment or indictment of a grand jury,” and that “[i]n all criminal
prosecutions, the accused shall enjoy the right to a speedy and public trial, by an impartial
jury.”113 Moreover, due process requires that the prosecution prove beyond a reasonable doubt
“every fact necessary to constitute the crime” with which an accused is charged, In re Winship.114
After Winship, the question arose whether a statute might authorize or require a more severe
penalty for a particular crime based on a fact—not included in the indictment, not found by the
jury, and not proven beyond a reasonable doubt. Pennsylvania passed a law under which various
serious crimes (rape, robbery, kidnapping, and the like) were subject to a mandatory minimum
penalty of imprisonment for five years, if the judge after conviction found by a preponderance of
the evidence that the defendant had been in visible possession of a firearm during the commission
of the offense.115 Had the Pennsylvania statute created a new series of crimes? For example, had it
supplemented its crime of rape with a new crime of rape while in visible possession of a firearm?
And if so, did the fact of visible possession have to be proven to the jury beyond a reasonable
doubt?116
The Supreme Court concluded that visible possession of a firearm under the statute was not an
element of a new series of crimes, but was instead a sentencing consideration that had been given
a legislatively prescribed weight.117 As such, the Pennsylvania statutory scheme neither offended
due process nor triggered any right to a separate jury finding.118

112 E.g., United States v. Haile, 685 F.3d 1211, 1222 (11th Cir. 2012)(“Given the serious nature of possessing a
machine gun in furtherance of drug-trafficking crimes, Beckford’s 30-year statutory mandatory minimum sentence
imposed under §924(c)(1)(B)(ii) is not grossly disproportionate to the offense”); United States v. Major, 676 F.3d 803,
812 (9th Cir. 2012)(“Major and Huff also argue that section 924(c) violates the Eighth Amendment. We have rejected
such challenges before. In United States v. Harris, 154 F.3d 1082, 1084 (9th Cir. 1990), we upheld a 95-year sentence
under section 924(c) against an Eighth Amendment challenge.... The sentences of Major and Huff are significantly
higher in number of years. No one could dispute that sentence of almost 750 years is harsh. But there is no difference in
principle between their sentences and the 95-year sentence we upheld in Harris”); United States v. Clark, 634 F.3d 874,

There followed a number of state and federal statutes under which facts that might earlier have
been treated as elements of a new crime were simply classified as sentencing factors. In some
instances, the new sentencing factor permitted imposition of a penalty far in excess of that
otherwise available for the underlying offense. For instance, the Supreme Court found no
constitutional defect in a statute which punished a deported alien for returning to the United
States by imprisonment for not more than two years, but which permitted the alien to be
sentenced to imprisonment for not more than 20 years upon a post-trial, judicial determination
that the alien had been convicted of a serious crime following deportation.119
Perhaps uneasy with the implications, the Court soon made it clear that “under the Due Process
Clause of the Fifth Amendment and the notice and jury trial guarantees of the Sixth Amendment,
any fact (other than prior conviction) that increases the maximum penalty for a crime must be
charged in an indictment, submitted to a jury, and proven beyond a reasonable doubt,” Apprendi v.
New Jersey
.120 Side opinions questioned the continued vitality of McMillan’s mandatory
minimum determination in light of the Apprendi.121
Initially unwilling to extend Apprendi to mandatory minimums in Harris,122 the Court did so in
Alleyne v. United States.123 Alleyne was convicted under the statute that imposes a series of

119 Almendarez-Torres v. United States, 523 U.S. 224, 247 (1998).
120 530 U.S. 466, 476 (2000)(emphasis added).
121 “Thus, the Court appears to hold that any fact that increases or alters the range of penalties to which a defendant is
exposed—which, by definition, must include increases or alterations to either the minimum or maximum penalties—
must be proved to a jury beyond a reasonable doubt. In McMillan, however, we rejected such a rule to the extent it
concerned those facts that increase or alter the minimum penalty to which a defendant is exposed. Accordingly, it is
incumbent on the Court not only to admit that it is overruling McMillan, but also to explain why such a course of action
is appropriate under normal principles of stare decisis,” 530 U.S. at 533 (O’Connor, with Kennedy, Breyer, JJ., and
Rehnquist, Ch.J., dissenting).
“[T]his traditional understanding—that a crime includes every fact that is by law a basis for imposing or increasing
punishment—continued well into the 20th century, at least until the middle of the century.... I think it clear that the
common-law rule would cover the McMillan situation of a mandatory minimum sentence.... [A defendant’s] expected
punishment has increased as a result of the narrowed range and that the prosecution is empowered, by invoking the
mandatory minimum, to require the judge to impose a higher punishment than he might wish. The mandatory minimum
entitles the government to more than it would otherwise be entitled.... Thus, the fact triggering the mandatory minimum
is part of the punishment sought to be inflicted; it undoubtedly enters into the punishment so as to aggravate it, and is
an act to which the law affixes punishment. Further ... it is likely that the change in the range available to the judge
affects his choice of sentences. Finally, in numerous cases ... the aggravating fact raised the whole range—both the top
and bottom. Those courts, in holding that such a fact was an element, did not bother with any distinction between
changes in the maximum and the minimum. What mattered was simply the overall increase in the punishment provided
by law,” 530 U.S. at 518, 521-22 (Thomas, J., concurring); see also, Rethinking Mandatory Minimums After Apprendi,

122 Harris v. United States, 536 U.S. 545, 568 (2002)(“Reaffirming McMillan and employing the approach outlined in
that case, we conclude that the federal provision at issue, 18 U.S.C. §924(c)(1)(A) (ii), is constitutional. Basing a 2-year
increase in the defendant’s minimum sentence on a judicial finding of brandishing does not evade the requirements of
the Fifth and Sixth Amendments. Congress ‘simply took one factor that has always been considered by sentencing
courts to bear on punishment ... and dictated the precise weight to be given that factor.’ McMillan, 477 U.S. at 89-90.
That factor need not be alleged in the indictment, submitted to the jury, or proved beyond a reasonable doubt”).
Of course, Harris was not meant to serve as either an endorsement or condemnation of mandatory minimum sentencing
as such: “The Court is well aware that many question the wisdom of mandatory minimum sentencing. Mandatory
minimums, it is often said, fail to account for the unique circumstances of offenders who warrant a lesser penalty.
These criticisms may be sound, but they would persist whether the judge or the jury found the facts given rise to the
minimum,” 530 U.S. at 568. See also, 530 U.S. at 570-71 (Breyer, J., concurring in part and concurring in the
judgment): “I do not mean to suggest my approval of mandatory minimum sentences as a matter of policy. During the

mandatory minimum penalties upon defendants who carry a firearm during and in furtherance of
a crime of violence (5 years for carrying; 7 years for brandishing; 10 years for discharging).124
The jury found him guilty of carrying; the court concluded the gun had been brandished.125 The
Sixth Amendment requires that the question of brandishing had to be found by the jury, the Court
declared:
Harris drew a distinction between facts that increase the statutory maximum and facts that
increase only the mandatory minimum. We conclude that this distinction is inconsistent with
our decision in Apprendi and with the original meaning of the Sixth Amendment. Any fact
that, by law, increases the penalty for a crime is an element that must be submitted to the jury
and found beyond a reasonable doubt. Mandatory minimum sentences increase the penalty
for a crime. It follows, then, that any fact that increases the mandatory minimum is an
element that must be submitted to the jury.126
Neither the Sixth Amendment, Apprendi, nor Alleyne limits Congress’s authority to establish
mandatory minimum sentences nor limits the authority of the courts to impose them. They simply
dictate the procedural safeguards that must accompany the exercise of that authority.127
Double Jeopardy
The Fifth Amendment declares that “No person shall be ... subject for the same offence to be
twice put in jeopardy of life or limb.... ”128 The double jeopardy clause protects against both
successive prosecutions and successive punishments for the same offense.129 The initial test for

“Mandatory minimum statutes are fundamentally inconsistent with Congress’ simultaneous effort to create a fair,
honest, and rational sentencing system through the use of Sentencing Guidelines. Unlike Guideline sentences, statutory
mandatory minimums generally deny the judge the legal power to depart downward, no matter how unusual the special
circumstances that call for leniency. They rarely reflect an effort to achieve sentencing proportionality—a key element
of sentencing fairness that demands that the law punish a drug ‘kingpin’ and a ‘mule’ differently. They transfer
sentencing power to prosecutors, who can determine sentences through the charges they decide to bring, and who
thereby have reintroduced much of the sentencing disparity that Congress created Guidelines to eliminate. They rarely
are based upon empirical study. And there is evidence that they encourage subterfuge leading to more frequent
downward departures (on a random basis), thereby making them comparatively ineffective means of guaranteeing
tough sentences.”

an impact on the defendant’s substantive rights and the presence of a miscarriage of justice should the error not be
corrected), see, e.g., United States v. Kirklin, 727 F.3d 711, 716017 (7th Cir. 2013)(no miscarriage of justice given the

whether a defendant has been twice tried or punished for the same offense or two different
offenses is whether each of the two purported offenses requires proof that the other does not.130
Thus, without violating the double jeopardy clause, an individual may be convicted and sentenced
for two violations of Section 924(c), if each has a different predicate offense.131 On the other
hand, there is no consensus over whether a single predicate offense may support conviction and
sentencing for two or more violations of Section 924(c).132 Moreover, the conviction for a serious
offense will ordinarily preclude prosecution or punishment for a lesser included offense, since the
lesser offense consists of only elements found in the more serious offense.133 For example, a
defendant may not be convicted and punished for both a violation of Section 924(c)(use of a
firearm in furtherance of a robbery) and of Section 924(j)(use of the same firearm in the same
robbery resulting in death).134
Commerce Clause Authority
The Constitution gives Congress the power to regulate commerce among the states and between
the United States and other nations.135 It also bestows on Congress the authority to enact such
legislation as it considered necessary and proper to carry into execution those other powers which
the Constitution vests in Congress, the Government of the United States, or any of its
Departments or officers.136 At the same time, the Constitution reserves to the states and the people
those powers which it has not otherwise conveyed.137 On occasion, the Supreme Court has held
that a particular statute was too far removed from Congress’s commerce clause power to make the
statute constitutionally viable.138 Defendants have sometimes seized upon these cases to assert
that Section 924(c) lies beyond Congress’s legislative reach. The courts have yet to be
convinced.139

The 18 U.S.C. 924(c) Tack-On in Cases Involving Drugs or Violence

Separation of Powers
While “it remains a basic principle of our constitutional scheme that one branch of the
Government may not intrude upon the central prerogatives of another,”140 the Supreme Court has
observed that “Congress has the power to define criminal punishments without giving the courts
any sentencing discretion.”141 Thus, the lower federal courts have regularly upheld mandatory
minimum statutes when challenged on separation of powers grounds,142 and the Supreme Court
has denied any separation of powers infirmity in the federal sentencing guideline system which at
the time might have been thought to produce its own form of mandatory minimums.143

140 Loving v. United States, 517 U.S. 748, 757 (1996).
141 United States v. Chapman, 500 U.S. 453, 467 (1991).

Cir. 2006).
143 Mistretta v. United States, 488 U.S. 361 (1989). Mistretta, sentenced under the guidelines to 18 months’
imprisonment for conspiracy to distribute cocaine, argued that the guidelines constituted an unconstitutional delegation
of Congress’s legislative authority and that the service of judges upon the Commission constituted extrajudicial service
at odds with the separation of powers doctrine. The Court rejected both arguments, concluding “that in creating the
Sentencing Commission ... Congress neither delegated excessive legislative power nor upset the constitutionally
mandated balance of powers among the coordinate Branches,” 488 U.S. at 412.
