U.S.S.G. §1B1.10
Reduction in Term of Imprisonment as a Result of Amended Guideline Range (Policy Statement)
(a) AUTHORITY.—
(1) IN GENERAL.—In a case in which a defendant is serving a term of imprisonment, and the guideline range applicable to that defendant has
subsequently been lowered as a result of an amendment to the Guidelines Manual listed in subsection (d) below, the court may reduce the
defendant’s term of imprisonment as provided by 18 U.S.C.
§ 3582(c)(2). As required by 18 U.S.C. § 3582(c)(2), any such reduction
in the defendant’s term of imprisonment shall be consistent with this
policy statement.
(2) EXCLUSIONS.—A reduction in the defendant’s term of imprisonment is
not consistent with this policy statement and therefore is not authorized under 18 U.S.C. § 3582(c)(2) if—
(A) none of the amendments listed in subsection (d) is applicable to
the defendant; or
(B) an amendment listed in subsection (d) does not have the effect of
lowering the defendant’s applicable guideline range.
(3) LIMITATION.—Consistent with subsection (b), proceedings under
18 U.S.C. § 3582(c)(2) and this policy statement do not constitute a
full resentencing of the defendant.
(b) DETERMINATION OF REDUCTION IN TERM OF IMPRISONMENT.—
(1) IN GENERAL.—In determining whether, and to what extent, a reduction in the defendant’s term of imprisonment under 18 U.S.C.
§ 3582(c)(2) and this policy statement is warranted, the court shall
determine the amended guideline range that would have been applicable to the defendant if the amendment(s) to the guidelines listed in
subsection (d) had been in effect at the time the defendant was sentenced. In making such determination, the court shall substitute only
the amendments listed in subsection (d) for the corresponding guideline provisions that were applied when the defendant was sentenced
and shall leave all other guideline application decisions unaffected.
(2) LIMITATION AND PROHIBITION ON EXTENT OF REDUCTION.—
(A) LIMITATION.—Except as provided in subdivision (B), the court
shall not reduce the defendant’s term of imprisonment under
18 U.S.C. § 3582(c)(2) and this policy statement to a term that is
less than the minimum of the amended guideline range determined under subdivision (1) of this subsection.
(B) EXCEPTION FOR SUBSTANTIAL ASSISTANCE.—If the term of imprisonment imposed was less than the term of imprisonment provided by the guideline range applicable to the defendant at the
time of sentencing pursuant to a government motion to reflect
the defendant’s substantial assistance to authorities, a reduction
comparably less than the amended guideline range determined
under subdivision (1) of this subsection may be appropriate.
(C) PROHIBITION.—In no event may the reduced term of imprisonment be less than the term of imprisonment the defendant has
already served.
(c) CASES INVOLVING MANDATORY MINIMUM SENTENCES AND SUBSTANTIAL ASSISTANCE.—If the case involves a statutorily required minimum sentence
and the court had the authority to impose a sentence below the statutorily
required minimum sentence pursuant to a government motion to reflect
the defendant’s substantial assistance to authorities, then for purposes of
this policy statement the amended guideline range shall be determined
without regard to the operation of §5G1.1 (Sentencing on a Single Count
of Conviction) and §5G1.2 (Sentencing on Multiple Counts of Conviction).
(d) COVERED AMENDMENTS.—Amendments covered by this policy statement
are listed in Appendix C as follows: 126, 130, 156, 176, 269, 329, 341, 371,
379, 380, 433, 454, 461, 484, 488, 490, 499, 505, 506, 516, 591, 599, 606,
657, 702, 706 as amended by 711, 715, 750 (parts A and C only), 782 (subject to subsection (e)(1)), and 821 (parts A and B, subpart 1 only and subject
to subsection (e)(2)).
(e) SPECIAL INSTRUCTIONS.—
(1) The court shall not order a reduced term of imprisonment based on
Amendment 782 unless the effective date of the court’s order is November 1, 2015, or later.
(2) The court shall not order a reduced term of imprisonment based on
Part A or Part B, Subpart 1 of Amendment 821 unless the effective
date of the court’s order is February 1, 2024, or later.
Commentary
Application Notes:
1. Application of Subsection (a).—
(A) Eligibility.—Eligibility for consideration under 18 U.S.C. § 3582(c)(2) is triggered only by
an amendment listed in subsection (d) that lowers the applicable guideline range (i.e., the
guideline range that corresponds to the offense level and criminal history category determined pursuant to §1B1.1(a)(1)–(7), which is determined before consideration of Part K of
Chapter Five and §1B1.1(b)). Accordingly, a reduction in the defendant’s term of imprisonment is not authorized under 18 U.S.C. § 3582(c)(2) and is not consistent with this policy
statement if: (i) none of the amendments listed in subsection (d) is applicable to the defendant; or (ii) an amendment listed in subsection (d) is applicable to the defendant but the
amendment does not have the effect of lowering the defendant’s applicable guideline range
because of the operation of another guideline or statutory provision (e.g., a statutory mandatory minimum term of imprisonment).
(B) Factors for Consideration.—
(i) In General.—Consistent with 18 U.S.C. § 3582(c)(2), the court shall consider the factors set forth in 18 U.S.C. § 3553(a) in determining: (I) whether a reduction in the
defendant’s term of imprisonment is warranted; and (II) the extent of such reduction,
but only within the limits described in subsection (b).
(ii) Public Safety Consideration.—The court shall consider the nature and seriousness
of the danger to any person or the community that may be posed by a reduction in the
defendant’s term of imprisonment in determining: (I) whether such a reduction is warranted; and (II) the extent of such reduction, but only within the limits described in
subsection (b).
(iii) Post-Sentencing Conduct.—The court may consider post-sentencing conduct of the
defendant that occurred after imposition of the term of imprisonment in determining:
(I) whether a reduction in the defendant’s term of imprisonment is warranted; and
(II) the extent of such reduction, but only within the limits described in subsection (b).
2. Application of Subsection (b)(1).—In determining the amended guideline range under subsection (b)(1), the court shall substitute only the amendments listed in subsection (d) for the
corresponding guideline provisions that were applied when the defendant was sentenced. All
other guideline application decisions remain unaffected.
3. Application of Subsection (b)(2).—Under subsection (b)(2), the amended guideline range determined under subsection (b)(1) and the term of imprisonment already served by the defendant
limit the extent to which the court may reduce the defendant’s term of imprisonment under
18 U.S.C. § 3582(c)(2) and this policy statement. Specifically, as provided in subsection (b)(2)(A),
if the term of imprisonment imposed was within the guideline range applicable to the defendant
at the time of sentencing, the court may reduce the defendant’s term of imprisonment to a term
that is no less than the minimum term of imprisonment provided by the amended guideline range
determined under subsection (b)(1). For example, in a case in which: (A) the guideline range
applicable to the defendant at the time of sentencing was 70 to 87 months; (B) the term of imprisonment imposed was 70 months; and (C) the amended guideline range determined under
subsection (b)(1) is 51 to 63 months, the court may reduce the defendant’s term of imprisonment,
but shall not reduce it to a term less than 51 months.
If the term of imprisonment imposed was outside the guideline range applicable to the defendant
at the time of sentencing, the limitation in subsection (b)(2)(A) also applies. Thus, if the term of
imprisonment imposed in the example provided above was not a sentence of 70 months (within
the guidelines range) but instead was a sentence of 56 months (constituting a sentence that is
below the otherwise applicable guideline range), the court likewise may reduce the defendant’s
term of imprisonment, but shall not reduce it to a term less than 51 months.
Subsection (b)(2)(B) provides an exception to this limitation, which applies if the term of imprisonment imposed was less than the term of imprisonment provided by the guideline range applicable to the defendant at the time of sentencing pursuant to a government motion to reflect the
defendant’s substantial assistance to authorities. In such a case, the court may reduce the defendant’s term, but the reduction is not limited by subsection (b)(2)(A) to the minimum of the
amended guideline range. Instead, as provided in subsection (b)(2)(B), the court may, if appropriate, provide a reduction comparably less than the amended guideline range. Thus, if the term
of imprisonment imposed in the example provided above was 56 months pursuant to a government motion to reflect the defendant’s substantial assistance to authorities (representing a reduction of 20 percent below the minimum term of imprisonment provided by the guideline range
applicable to the defendant at the time of sentencing), a reduction to a term of imprisonment of
41 months (representing a reduction of approximately 20 percent below the minimum term of
imprisonment provided by the amended guideline range) would amount to a comparable reduction and may be appropriate.
The provisions authorizing such a government motion are §5K1.1 (Substantial Assistance to Authorities) (authorizing the court, upon government motion, to impose a sentence that is below the
otherwise applicable guideline range based on the defendant’s substantial assistance); 18 U.S.C.
§ 3553(e) (authorizing the court, upon government motion, to impose a sentence below a statutory
minimum to reflect the defendant’s substantial assistance); and Fed. R. Crim. P. 35(b) (authorizing the court, upon government motion, to reduce a sentence to reflect the defendant’s substantial assistance).
In no case, however, shall the term of imprisonment be reduced below time served. See subsection (b)(2)(C). Subject to these limitations, the sentencing court has the discretion to determine
whether, and to what extent, to reduce a term of imprisonment under this section.
4. Application of Subsection (c).—As stated in subsection (c), if the case involves a statutorily
required minimum sentence and the court had the authority to impose a sentence below the
statutorily required minimum sentence pursuant to a government motion to reflect the defendant’s substantial assistance to authorities, then for purposes of this policy statement the
amended guideline range shall be determined without regard to the operation of §5G1.1 (Sentencing on a Single Count of Conviction) and §5G1.2 (Sentencing on Multiple Counts of Conviction). For example:
(A) Defendant A is subject to a mandatory minimum term of imprisonment of 120 months. The
original guideline range at the time of sentencing was 135 to 168 months, which is entirely
above the mandatory minimum, and the court imposed a sentence of 101 months pursuant
to a government motion to reflect the defendant’s substantial assistance to authorities. The
court determines that the amended guideline range as calculated on the Sentencing Table
is 108 to 135 months. Ordinarily, §5G1.1 would operate to restrict the amended guideline
range to 120 to 135 months, to reflect the mandatory minimum term of imprisonment. For
purposes of this policy statement, however, the amended guideline range remains 108 to
135 months.
To the extent the court considers it appropriate to provide a reduction comparably less than
the amended guideline range pursuant to subsection (b)(2)(B), Defendant A’s original sentence of 101 months amounted to a reduction of approximately 25 percent below the minimum of the original guideline range of 135 months. Therefore, an amended sentence of
81 months (representing a reduction of approximately 25 percent below the minimum of
the amended guideline range of 108 months) would amount to a comparable reduction and
may be appropriate.
(B) Defendant B is subject to a mandatory minimum term of imprisonment of 120 months. The
original guideline range at the time of sentencing (as calculated on the Sentencing Table)
was 108 to 135 months, which was restricted by operation of §5G1.1 to a range of 120 to
135 months. See §5G1.1(c)(2). The court imposed a sentence of 90 months pursuant to a
government motion to reflect the defendant’s substantial assistance to authorities. The
court determines that the amended guideline range as calculated on the Sentencing Table
is 87 to 108 months. Ordinarily, §5G1.1 would operate to restrict the amended guideline
range to precisely 120 months, to reflect the mandatory minimum term of imprisonment.
See §5G1.1(b). For purposes of this policy statement, however, the amended guideline range
is considered to be 87 to 108 months (i.e., unrestricted by operation of §5G1.1 and the statutory minimum of 120 months).
To the extent the court considers it appropriate to provide a reduction comparably less than
the amended guideline range pursuant to subsection (b)(2)(B), Defendant B’s original sentence of 90 months amounted to a reduction of approximately 25 percent below the original
guideline range of 120 months. Therefore, an amended sentence of 65 months (representing
a reduction of approximately 25 percent below the minimum of the amended guideline
range of 87 months) would amount to a comparable reduction and may be appropriate.
5. Application to Amendment 750 (Parts A and C Only).—As specified in subsection (d), the
parts of Amendment 750 that are covered by this policy statement are Parts A and C only. Part A
amended the Drug Quantity Table in §2D1.1 for crack cocaine and made related revisions to the
Drug Equivalency Tables (currently called Drug Conversion Tables) in the Commentary to
§2D1.1 (see §2D1.1, comment. (n.8)). Part C deleted the cross reference in §2D2.1(b) under which
an offender who possessed more than 5 grams of crack cocaine was sentenced under §2D1.1.
6. Application to Amendment 782.—As specified in subsection (d) and (e)(1), Amendment 782
(generally revising the Drug Quantity Table and chemical quantity tables across drug and chemical types) is covered by this policy statement only in cases in which the order reducing the defendant’s term of imprisonment has an effective date of November 1, 2015, or later.
A reduction based on retroactive application of Amendment 782 that does not comply with the
requirement that the order take effect on November 1, 2015, or later is not consistent with this
policy statement and therefore is not authorized under 18 U.S.C. § 3582(c)(2).
Subsection (e)(1) does not preclude the court from conducting sentence reduction proceedings and
entering orders under 18 U.S.C. § 3582(c)(2) and this policy statement before November 1, 2015,
provided that any order reducing the defendant’s term of imprisonment has an effective date of
November 1, 2015, or later.
7. Application to Amendment 821 (Parts A and B, Subpart 1 Only).—As specified in subsection (d), the parts of Amendment 821 that are covered by this policy statement are Parts A and B,
Subpart 1 only, subject to the special instruction at subsection (e)(2). Part A amended §4A1.1
(Criminal History Category) to limit the overall criminal history impact of “status points”
(i.e., the additional criminal history points given to defendants for the fact of having committed
the instant offense while under a criminal justice sentence, including probation, parole, supervised release, imprisonment, work release, or escape status). Part B, Subpart 1 created a new
Chapter Four guideline at §4C1.1 (Adjustment for Certain Zero-Point Offenders) to provide a
decrease of two levels from the offense level determined under Chapters Two and Three for defendants who did not receive any criminal history points under Chapter Four, Part A and whose
instant offense did not involve specified aggravating factors.
The special instruction at subsection (e)(2) delays the effective date of orders reducing a defendant’s term of imprisonment to a date no earlier than February 1, 2024. A reduction based on the
retroactive application of Part A or Part B, Subpart 1 of Amendment 821 that does not comply
with the requirement that the order take effect no earlier than February 1, 2024, is not consistent
with this policy statement and therefore is not authorized under 18 U.S.C. § 3582(c)(2). Subsection (e)(2), however, does not preclude the court from conducting sentence reduction proceedings
and entering orders under 18 U.S.C. § 3582(c)(2) and this policy statement before February 1,
2024, provided that any order reducing the defendant’s term of imprisonment has an effective
date of February 1, 2024, or later.
8. Supervised Release.—
(A) Exclusion Relating to Revocation.—Only a term of imprisonment imposed as part of
the original sentence is authorized to be reduced under this section. This section does not
authorize a reduction in the term of imprisonment imposed upon revocation of supervised
release.
(B) Modification Relating to Early Termination.—If the prohibition in subsection (b)(2)(C)
relating to time already served precludes a reduction in the term of imprisonment to the
extent the court determines otherwise would have been appropriate as a result of the
amended guideline range determined under subsection (b)(1), the court may consider any
such reduction that it was unable to grant in connection with any motion for early termination of a term of supervised release under 18 U.S.C. § 3583(e)(1). See §5D1.4 (Modification, Early Termination, and Extension of Supervised Release (Policy Statement)). However, the fact that a defendant may have served a longer term of imprisonment than the
court determines would have been appropriate in view of the amended guideline range determined under subsection (b)(1) shall not, without more, provide a basis for early termination of supervised release. Rather, the court should take into account the totality of circumstances relevant to a decision to terminate supervised release, including the term of supervised release that would have been appropriate in connection with a sentence under the
amended guideline range determined under subsection (b)(1).
9. Use of Policy Statement in Effect on Date of Reduction.—Consistent with subsection (a)
of §1B1.11 (Use of Guidelines Manual in Effect on Date of Sentencing), the court shall use the
version of this policy statement that is in effect on the date on which the court reduces the defendant’s term of imprisonment as provided by 18 U.S.C. § 3582(c)(2).
Background: Section 3582(c)(2) of title 18, United States Code, provides: “[I]n the case of a defendant
who has been sentenced to a term of imprisonment based on a sentencing range that has subsequently
been lowered by the Sentencing Commission pursuant to 28 U.S.C. § 994(o), upon motion of the defendant or the Director of the Bureau of Prisons, or on its own motion, the court may reduce the term
of imprisonment, after considering the factors set forth in section 3553(a) to the extent that they are
applicable, if such a reduction is consistent with applicable policy statements issued by the Sentencing
Commission.”
This policy statement provides guidance and limitations for a court when considering a motion
under 18 U.S.C. § 3582(c)(2) and implements 28 U.S.C. § 994(u), which provides: “If the Commission
reduces the term of imprisonment recommended in the guidelines applicable to a particular offense or
category of offenses, it shall specify in what circumstances and by what amount the sentences of prisoners serving terms of imprisonment for the offense may be reduced.” The Supreme Court has concluded that proceedings under section 3582(c)(2) are not governed by United States v. Booker, 543 U.S.
220 (2005), and this policy statement remains binding on courts in such proceedings. See Dillon v.
United States, 560 U.S. 817 (2010).
Among the factors considered by the Commission in selecting the amendments included in subsection (d) were the purpose of the amendment, the magnitude of the change in the guideline range
made by the amendment, and the difficulty of applying the amendment retroactively to determine an
amended guideline range under subsection (b)(1).
The listing of an amendment in subsection (d) reflects policy determinations by the Commission
that a reduced guideline range is sufficient to achieve the purposes of sentencing and that, in the sound
discretion of the court, a reduction in the term of imprisonment may be appropriate for previously
sentenced, qualified defendants. The authorization of such a discretionary reduction does not otherwise affect the lawfulness of a previously imposed sentence, does not authorize a reduction in any
other component of the sentence, and does not entitle a defendant to a reduced term of imprisonment
as a matter of right.
The Commission has not included in this policy statement amendments that generally reduce
the maximum of the guideline range by less than six months. This criterion is in accord with the
legislative history of 28 U.S.C. § 994(u) (formerly § 994(t)), which states: “It should be noted that the
Committee does not expect that the Commission will recommend adjusting existing sentences under
the provision when guidelines are simply refined in a way that might cause isolated instances of existing sentences falling above the old guidelines* or when there is only a minor downward adjustment
in the guidelines. The Committee does not believe the courts should be burdened with adjustments in
these cases.” S. Rep. 225, 98th Cong., 1st Sess. 180 (1983).
*So in original. Probably should be “to fall above the amended guidelines”.
