The Safety Valve and Substantial Assistance
Charles Doyle

Senior Specialist in
American Public Law
Federal law requires a sentencing judge to impose a minimum sentence of imprisonment

following conviction for any of a number of federal offenses. Congress has created three
exceptions. Two are available in any case where the prosecutor asserts that the defendant has

provided substantial assistance in the criminal investigation or prosecution of another. The other,
commonly referred to as the safety valve, is available, without the government’s approval, for a handful of the more
commonly prosecuted drug trafficking and unlawful possession offenses that carry minimum sentences.
Qualification for the substantial assistance exceptions is ordinarily only possible upon the motion of the government. In rare
cases, the court may compel the government to file such a motion when the defendant can establish that the refusal to do so
was based on constitutionally invalid considerations, was in derogation of a plea bargain obligation, or was the product of
bad faith.
Qualification for the safety valve exception requires a defendant to satisfy five criteria. His past criminal record must be
minimal; he must not have been a leader, organizer, or supervisor in the commission of the offense; he must not have used
violence in the commission of the offense, and the offense must not have resulted in serious injury; and prior to sentencing,
he must tell the government all that he knows of the offense and any related misconduct.
In response to a congressional request, the U.S. Sentencing Commission recommended expansion of the safety valve. The
First Step Act, P.L. 115-391, broadened the safety valve for the benefit of (1) defendants with slightly more serious criminal
records and (2) defendants convicted under the Maritime Drug Enforcement Act.

Federal Mandatory Minimum Sentences: The Safety Valve and Substantial Assistance Exceptions

Introduction
The United States Code houses hundreds of offenses punishable by a mandatory minimum term
of imprisonment.1 Although only a handful of these mandatory minimum offenses are prosecuted
with any regularity, drug trafficking offenses accounted for over three-quarters of the total.2
Congress has created three procedures that make punishment for these offenses a little less
mandatory. One, the so-called safety valve (18 U.S.C. § 3553(f)), permits a sentencing court to
disregard a statutory minimum sentence for the benefit of a low-level, nonviolent, cooperative
defendant with a minimal prior criminal record, convicted under several mandatory minimum
controlled substance offenses. The other two, 18 U.S.C. § 3553(e) and Rule 35(b) of the Federal
Rules of Criminal Procedure,3 afford a sentencing court comparable latitude but only on the
motion of the prosecutor, based on the defendant’s substantial assistance to the government, and
without regard to the offense charged.
In October 2009, Congress instructed the U.S. Sentencing Commission to prepare a report on the
mandatory minimum sentencing provisions under federal law.4 In early 2010, the commission
conducted a survey of federal district court judges regarding their views on mandatory minimum
sentencing. A majority of those responding endorsed amendments to the safety valve and
substantial assistance exceptions.5 The commission also held a public hearing at which several
witnesses urged adjustments in the safety valve and substantial assistance provisions.6 The
commission subsequently recommended that Congress consider expanding the safety valve to
cover other offenses and to reach offenders with a slightly more extensive prior criminal record.7
The First Step Act authorized safety-valve relief for convictions under the Maritime Drug
Enforcement Act and for defendants with slightly more extensive prior criminal records.8

Federal Mandatory Minimum Sentences: The Safety Valve and Substantial Assistance Exceptions

Safety Valve
Background
Low-level drug offenders can escape some of the otherwise applicable mandatory minimum
sentencing if they qualify for the safety valve.9 Congress created the safety valve after it became
concerned that the mandatory minimum sentencing provisions could have resulted in equally
severe penalties for both the more and the less culpable offenders.10 The Safety Valve extends to
qualified offenders convicted of violations of the drug trafficking, simple possession, attempt, or
conspiracy provisions of the Controlled Substances or Controlled Substances Import and Export
acts.11
It does not extend to the mandatory minimum sentences that attend some of the other controlled
substance offenses, even those closely related to the covered offenses. For instance, it does not
cover convictions under the statute that proscribes drug trafficking near schools, playgrounds, or
public housing facilities and that sets the penalties for violation at twice those set for simple drug
trafficking.12 In addition, until the First Step Act, safety valve relief did not reach those convicted
under the Maritime Drug Law Enforcement Act (MDLEA), even though the MDLEA proscribes
conduct closely related to the smuggling and trafficking activities outlawed in the Controlled
Substances Import and Export Act.13
The prosecution need not prove that a defendant is ineligible for safety valve relief. The Supreme
Court did hold in Alleyne v. United States “that any fact that increases the mandatory minimum is
an ‘element’ [of the offense] that must be submitted to the jury” and proved beyond a reasonable
doubt.14 Subsequent lower appellate courts, however, have held that Alleyne does not require a
jury verdict or application of the reasonable doubt standard.15 Thus, for the convictions to which
the safety valve applies, the defendant must convince the sentencing court by a preponderance of

v. Koons, 300 F.3d 985, 994 (8th Cir. 2002). One Sentencing Commission witness indicated that “in districts where

disqualifying criminal history point total.17 He may not have used violence or a dangerous
weapon in connection with the offense.18 He may not have been an organizer or leader of the drug
enterprise.19 He must have provided the government with all the information and evidence at his

Disqualifying Criminal History Point Total
[T]he defendant does not have –
(A) more than 4 criminal history points, excluding any criminal history points resulting
from a 1-point offense, as determined under the sentencing guidelines;
(B) a prior 3-point offense, as determined under the sentencing guidelines; and
(C) a prior 2-point violent offense, as determined under the sentencing guidelines.22
The criminal history point disqualification refers to the defendant’s prior criminal record. Section
3553(f)(1) disqualifies only those who have a prior 2-point violent offense, more than 4 criminal
history points and a prior 3-point offense.23 The Sentencing Guidelines assign criminal history
points based on a defendant’s past criminal record. Prior sentences of imprisonment or juvenile
detention of less than 60 days are assigned a single criminal history point.24
Prior sentences of imprisonment or juvenile detention of from 60 days up to a year and a month
are assigned two criminal history points; as are sentences imposed for offenses committed while

 Similar offenses to those listed “by whatever name they are

Only the Nonviolent
[T]he defendant did not use violence or credible threats of violence or possess a firearm or
other dangerous weapon (or induce another participant to do so) in connection with the
offense, 18 U.SC. § 3553(f)(2).37
[T]he offense did not result in death or serious bodily injury to any person, 18 U.S.C. §
3553(f)(3).38
The safety valve has two disqualifications designed to reserve its benefits to the nonviolent. The
weapon or threat-of-violence disqualification turns upon the defendant’s conduct or the conduct
of those he “aided or abetted, counseled, commanded, induced, procured, or willfully caused.”39 It
is not triggered by the conduct of a co-conspirator, unless the defendant aided, abetted, or

imprisonment of at least thirty days, or (B) the prior offense was similar to an instant offense: careless or reckless
driving[;] contempt of court[;] disorderly conduct or disturbing the peace[;] driving without a license or with a revoked
or suspended license[;] false information to a police officer[;] gambling[;] hindering or failure to obey a police
officer[;] insufficient funds check[;], leaving the scene of an accident[;] non-support[;] prostitution[;] resisting arrest[;
and] trespassing”). E.g., United States v. Vazquez, 719 F.3d 1086, 1092-93 (9th Cir. 2013) (a suspended sentence
following conviction for driving with a suspended license does not count when the defendant is not sentenced to
probation and the applicable state law does not consider probation an implicit component of a suspended sentence).
36 U.S.S.G. §§ 4A1.2(c)(1), (c)(2). The Sentencing Guidelines suggest a number of factors to assist in the determination
of whether an unlisted offense may be consider “similar” for purposes of Section 4A1.2(c): “(i) a comparison of
punishments imposed for the listed and unlisted offenses; (ii) the perceived seriousness of the offense as indicated by
the level of punishment; (iii) the elements of the offense; (iv) the level of culpability involved; and (v) the degree to
which the commission of the offense indicates a likelihood of recurring criminal conduct,” U.S.S.G. §4A1.2, cmt.
n.12(A). See, e.g., United States v. Bravo, 26 F.4th 387, 392-96 (7th Cir. 2022) (holding that state streetgang contact

counselled the co-conspirator’s violence or possession.40 Disqualifying firearm possession must
be “in connection with the offense” that carries a mandatory minimum, i.e., to have “the potential
of facilitating the . . . offense.”41 Possession may be either actual or constructive.42 Constructive
possession is the dominion or control over a firearm or the place where one is located.43
Disqualification requires the threat of violence or possession of a firearm “in connection with the
offense,” sometimes characterized as “active possession.”44 In many instances, possession of a
firearm in a location where drugs are stored or transported, or where transactions occur, will be
enough to support an inference of possession in connection with the drug offense of conviction.45
“[E]ven a single intimidating confrontation [is] enough to constitute a credible threat” and is
consequently safety valve disqualifying.46 Nevertheless, “not all defendants who receive the

valve. A defendant who receives a firearm enhancement under § 2D1.1(b)(1) can still secure
safety valve relief if he shows that it is more likely than not that the possession of the firearm was
not connected with the offense.”47
The Sentencing Guidelines define “serious bodily injury” for purposes of Section 3553(f)(3) as an
“injury involving extreme physical pain or the protracted impairment of a function of a bodily
member, organ, or mental faculty; or requiring medical intervention such as surgery,
hospitalization, or physical rehabilitation.”48 On its face, the definition would include serious
bodily injuries, such as hospitalization, suffered by the defendant as a result of the offense.49
Moreover, a defendant is more likely to be disqualified under Section 3553(f)(3) if a fellow
conspirator seriously injures a victim than would be the case under Section 3553(f)(2) if the
conspirator merely carries a firearm.50
Only Single or Low-Level Offenders
[T]he defendant was not an organizer, leader, manager, or supervisor of others in the
offense, as determined under the sentencing guidelines and was not engaged in a continuing
criminal enterprise, as defined in Section 408 of the Controlled Substances Act, 18 U.S.C.
§ 3553(f)(4)(emphasis added).
Under the corresponding sentencing guideline, a defendant is an “organizer, leader, manager, or
supervisor of others in the offense, as determined under the sentencing guidelines” if he “receives
an adjustment for an aggravated role under [U.S.S.G.] §[]3B1.1 (Aggravating Role).”51 Such an
adjustment is warranted if the government establishes that the defendant exercised control over
one of the other participants in the offense or the organization of the criminal activity.52
Conversely, to avoid disqualification under § 3553(f)(4) a defendant must establish that he is not
“an organizer, leader, manager, or supervisor of others in the offense.”53 “Although the evidence
of [a defendant’s] general coordination of criminal activities is not itself enough to show that he
was an ‘organizer,’ [for U.S.S.G. § 3B1.1 purposes] the entire record of evidence sufficies to

49 The Eleventh Circuit in a nonbinding opinion seems to have come to the same conclusion. United States v. Valencia-
Vergara, 264 Fed. Appx. 832, 836 (11th Cir. 2008) (“The district court did not clearly err in denying Valencia-Vergara
a reduction under the safety valve provisions. The evidence shows that both he and one of his codefendants sustained
second and third degree burns on their bodies, for which they had to be treated at a hospital.”).
50 Compare 18 U.S.C. § 3553(f)(3) (“the offense did not result in death or serious bodily injury”) with id.§ 3553(f)(2)
(emphasis added) (“the defendant did not use violence or credible threats of violence or possess a firearm or other
dangerous weapon (or induce another participant to do so) in connection with the offense),”). See United States v.
Grimmett, 150 F.3d 958, 960 (8th Cir. 1998) (reversing on other grounds a district court decision that included that
denial of safety valve relief “because of Kerns’ murder by conspirators”).
51 U.S.S.G. § 5C1.2(a)(4) (“the defendant was not an organizer, leader, manager, or supervisor of others in the offense,
as determined under the sentencing guidelines and was not engaged in a continuing criminal enterprise, as defined in 21
U.S.C. 848.”); U.S.S.G. § 5C1.2 cmt. n.6 (“As a practical matter, it should not be necessary to apply this prong of
subsection (a)(4) because (i) this [safety valve] section does not apply to a conviction under 21 U.S.C. § 848, and (ii)
any defendant who ‘engaged in a continuing criminal enterprise’ but is convicted of an offense to which this section
applies will be an ‘organizer, leader, manager, or supervisor of others in the offense.’”).

Tell All
[N]ot later than the time of the sentencing hearing, the defendant has truthfully provided to
the Government all information and evidence the defendant has concerning the offense or
offenses that were part of the same course of conduct or of a common scheme or plan, but
the fact that the defendant has no relevant or useful other information to provide or that the
Government is already aware of the information shall not preclude a determination by the
court that the defendant has complied with this requirement, 18 U.S.C. § 3553(f)(5).55
At one time the most heavily contested safety valve prerequisite, Section 3553(f)(5) requires full
disclosure on the part of the defendant. As in the case of the other prerequisites, the defendant
here bears the burden of establishing his qualification for safety valve relief.56 The requirement
extends not only to information concerning the crime of conviction,57 but also to information
concerning other crimes that “were part of the same course of conduct or of a common scheme or
plan,” including uncharged related conduct.58 The court, not the government, must determine
whether the defendant has carried his burden,59 based on specifics in the record, rather than mere
speculation or conjecture.60
Neither Section 3553(f) nor the Sentencing Guidelines explain what form the defendants’ full
disclosure must take. At least one court has held that under rare circumstances disclosure through
the defendant’s testimony at trial may suffice.61 Most often the defendant provides the
information during an interview with prosecutors or by a proffer. The defendant must disclose the

information to the prosecutor, however. Disclosure to the probation officer during preparation of
the presentence report is not sufficient.62 Moreover, a defendant does not necessarily qualify for
relief merely because he has proffered a statement and invited the prosecution to identify any
additional information it seeks; for “the government is under no obligation to solicit information
from a defendant.”63 The defendant must provide the government with all the relevant
information in his possession.64 And, he must do so “no later than the time of the sentencing
hearing.”65 Information offered after the sentencing hearing does not qualify,66 although
information offered following appellate remand for resentencing and prior to the resentencing
hearing may qualify.67 On the other hand, past lies do not render a defendant ineligible for relief
under the truthful disclosure criterion of the safety valve, although they may undermine his
credibility.68
Substantial Assistance
Background
Three provisions authorize federal courts to reduce a defendant’s sentence on the motion of the
government for substantial assistance: Rule 35(b) of the Federal Rules of Criminal Procedure, 18
U.S.C. § 3553(e), and section 5K1.1 of the U.S. Sentencing Guidelines. Only section 3553(e) and

Federal Mandatory Minimum Sentences: The Safety Valve and Substantial Assistance Exceptions

safety valve, neither section 3553(e) nor Rule 35(b) is limited to mandatory minimums
established for controlled substance offenses.69
18 U.S.C. § 3553(e)
The substantial assistance provision under 18 U.S.C. § 3553(e), passed with little fanfare in the
twilight of the 99th Congress as part of the massive Anti-Drug Abuse Act of 1986, was legislation
that established or increased a number of mandatory minimum sentencing provisions.70 The
section continues in its original form virtually unchanged:
(e) Limited Authority To Impose a Sentence Below a Statutory Minimum. - Upon motion
of the Government, the court shall have the authority to impose a sentence below a level
established by statute as a minimum sentence
so as to reflect a defendant’s substantial
assistance in the investigation or prosecution of another person who has committed an
offense. Such sentence shall be imposed in accordance with the guidelines and policy
statements issued by the Sentencing Commission pursuant to section 994 of title 28, United
States Code.71
The section passed between the date authorizing creation of the Sentencing Guidelines and the
date they became effective. Rather than replicate the language of Section 3553(e), the guidelines
contain a corresponding section that authorizes a sentencing court to depart from the minimum
sentence called for by the guidelines, rather than the statutory mandatory minimum.72
“Upon the Motion of the Government”
As a general rule, a defendant is entitled to a sentence below an otherwise applicable statutory
minimum under the provisions of Section 3553(e) only if the government and the court agree.73

69 18 U.S.C. § 3553(e); FED. R. CRIM. P. 35(b)(4) (“When acting under Rule 35(b), the court may reduce the sentence to
a level below the minimum sentence established by statute.”).

71 18 U.S.C. § 3553(e) (emphasis added). In the only amendment to Section 3553(e), Section 4002(a)(8) of P.L. 107-
273 (2002) changed the phrase “as minimum sentence” to “as a minimum sentence.”
72 U.S.S.G. § 5K1.1: “Substantial Assistance to Authorities (Policy Statement). Upon motion of the government stating
that the defendant has provided substantial assistance in the investigation or prosecution of another person who has
committed an offense, the court may depart from the guidelines.
“(a) The appropriate reduction shall be determined by the court for reasons stated that may include, but are not limited
to, consideration of the following:
“(1) the court’s evaluation of the significance and usefulness of the defendant’s assistance, taking into consideration the
government’s evaluation of the assistance rendered;
“(2) the truthfulness, completeness, and reliability of any information or testimony provided by the defendant;
“(3) the nature and extent of the defendant’s assistance;
(4) any injury suffered, or any danger or risk of injury to the defendant or his family resulting from his assistance;
(5) the timeliness of the defendant’s assistance.” (Emphasis added). Note that § 3553(e) permits a sentence below the
otherwise applicable statutory mandatory minimum while U.S.S.G. § 5K1.1 permits a sentence below the otherwise
applicable sentencing guideline range.

Federal Mandatory Minimum Sentences: The Safety Valve and Substantial Assistance Exceptions

The courts have acknowledged that due process or equal protection or other constitutional
guarantees may provide a narrow exception. “Thus, a defendant would be entitled to relief if a
prosecutor refused to file a substantial-assistance motion, say, because of the defendant’s race or
religion.”74 A defendant is entitled to relief if the government’s refusal constitutes a breach of its
plea agreement.75 A defendant is also “entitled to relief if the prosecutor’s refusal to move was not
rationally related to any legitimate Government end.”76 Some courts have suggested that a
defendant is entitled to relief if the prosecution refuses to move under circumstances that “shock
the conscience of the court,” or that demonstrate bad faith, or for reasons unrelated to substantial
assistance.77 A majority of the judges who answered the Sentencing Commission’s survey agreed
that relief under Section 3553(e) should be available even in the absence of motion from the
prosecutor.78
Despite their similarities, Section 3553(e) and U.S.S.G. Section 5K1.1 are not the same. A motion
under Section 3553(e) authorizes a sentence beneath the mandatory minimum, and a motion
under U.S.S.G. Section 5K1.1 authorizes a sentence beneath the applicable Sentencing Guideline
range. Thus, a motion under Section 5K1.1 will ordinarily not be construed as a motion under
Section 3553(e), permitting a district court to impose a sentence below an otherwise applicable
mandatory minimum sentencing requirement.79
“To Reflect a Defendant’s Substantial Assistance”
Any sentence imposed below the statutory minimum by virtue of Section 3553(e) must be based
on the extent of the defendant’s assistance; it may not reflect considerations unrelated to such

assistance.80 It has been suggested, however, that a court may use the Section 5K1.1 factors for
that determination, that is, “(1) the court’s evaluation of the significance and usefulness of the
defendant’s assistance, taking into consideration the government’s evaluation of the assistance
rendered; (2) the truthfulness, completeness, and reliability of any information or testimony
provided by the defendant; (3) the nature and extent of the defendant’s assistance; (4) any injury
suffered, or any danger or risk of injury to the defendant or his family resulting from his
assistance; [and] (5) the timeliness of the defendant’s assistance.”81
The substantial assistance exception makes possible convictions that might otherwise be
unattainable. Yet, it may also lead to “inverted sentencing,” that is, a situation in which “the more
serious the defendant’s crimes, the lower the sentence—because the greater his wrongs, the more
information and assistance he had to offer to a prosecutor”; while in contrast the exception is of
no avail to the peripheral offender who can provide no substantial assistance.82 Perhaps for this
reason, most of the judges who responded to the Sentencing Commission survey agreed that a
sentencing court should not be limited to assistance-related factors and should be allowed to use
the generally permissible sentencing factors when calculating a sentence under Section 3553(e).83
Rule 35(b)
In the before-and-after sentencing tale of avoiding a statutory mandatory minimum for substantial
assistance, Rule 35(b) is the after. It is available only after sentencing.84 The rule features a two-
pronged post-sentence authorization for sentence reduction at the behest of the government. First,
the government may file a motion for sentence reduction, including reduction below an otherwise
applicable mandatory minimum, if it does so within a year of sentencing.85 Second, the

(en banc) (“Where a court has authority to sentence below a statutory minimum only by virtue of a government motion
under § 3553(e), the reduction below the statutory minimum must be based exclusively on assistance-related
considerations.”); see also United States v. Spann, 682 F.3d 565, 566 (7th Cir. 2012); United States v. Winebarger, 664

2009) (citing United States v. Richardson, 521 F.3d at 159) (“According to the Second Circuit in Richardson,
considering U.S.S.G. § 5K1.1’s factors is appropriate in determining the extent of a departure below the statutory

the minimum sentence established by statute.”).

government may file a comparable motion a year after sentencing, but only under narrow
circumstances that excuse the failure to make a more timely motion.86 A court may not grant the
government’s motion, filed more than a year after sentencing, unless the case falls within one of
three narrow and narrowly construed exceptions noted above.87
A motion by the government is a prerequisite to relief, and the government’s decision to refuse to
move can be overcome only where the government’s silence is unconstitutionally grounded or
based on some rationale not reasonably related to a legitimate government end.88 Nevertheless,
there is some authority for the proposition that a defendant must be given a chance to respond to
the specifics of the government’s motion.89
A district court, faced with a Rule 35(b) motion, must determine whether the defendant in fact
rendered substantial assistance and if so what level of reduction, if any, is warranted.90 As part of
its assessment, the court may consider the defendant’s assistance before sentencing, and may, but
is not required to, consider the general sentencing factors found in 18 U.S.C. § 3553(a).91

86 Id. at 35(b)(2), (4) (“(2) Upon the government's motion made more than one year after sentencing, the court may
reduce a sentence if the defendant's substantial assistance involved: (A) information not known to the defendant until
one year or more after sentencing; (B) information provided by the defendant to the government within one year of
sentencing, but which did not become useful to the government until more than one year after sentencing; or (C)
information the usefulness of which could not reasonably have been anticipated by the defendant until more than one
year after sentencing and which was promptly provided to the government after its usefulness was reasonably apparent
to the defendant. … (4) When acting under Rule 35(b), the court may reduce the sentence to a level below the
minimum sentence established by statute.”). If the defendant’s sentence is vacated on appeal, a Section 3553(e) motion
rather than a Rule 35(b) motion is the appropriate vehicle for relief during resentencing. United States v. Tidwell, 827
F.3d 761, 762 n.2 (8th Cir. 2016).

for a reduction in sentence based on his substantial assistance. Indeed, the Government’s decision whether to file such
motions based on substantial assistance is generally unreviewable ‘subject to constitutional limitations that district
courts can enforce.”” (quoting Wade v. United States, 504 U.S. 181, 185 (1992))); United States v. Scarpa, 861 F.3d

motion . . . . [T]he court denied [Redacted] an opportunity to provide his own recommendation and present argument
and accompanying evidence regarding the sentence reduction that he believed was warranted for his substantial
assistance.”) (The court redacted the name of the defendant throughout); but see United States v. McMahan, 872 F.3d

the Second Circuit [in United States v. Gangi, 45 F.3d 28 (2d Cir. 1995)] has found that [U.S.S.G.] § 5K1.1 compels a
reading of Rule 35(b) to require a right to be heard.”).
90 United States v. Doe, 938 F.3d 15, 17 (2d Cir 2019) (‘“In deciding a Rule 35(b) motion, a district court makes two

that the defendant did provide substantial assistance, it must then determine whether to reduce the sentence, and, if so,
to what extent” (quoting United States v. Katsman, 905 F.3d 672, 674 (2d Cir. 2018))).

departures under Rule 35(b), this court has explained that, when making the threshold decision of whether to grant a

other factors into account when determining the extent of the departure.”) (emphasis of the court); United States v.
