The Sentencing Reform Act provides that a district court has “limited authority to impose a sentence below a statutory minimum,” upon motion of the government, “so as to reflect a defendant’s substantial assistance in the investigation or prosecution of another person who has committed an offense.” 18 U.S.C. § 3553(e). This case presents the question whether a district court, after reducing a sentence based on substantial assistance pursuant to § 3553(e), may reduce the sentence further based on factors, other than assistance, set forth in 18. U.S.C. § 3553(a). We' hold that it may not. Where a court *1131 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.
Amanda Williams pled guilty to conspiracy to distribute more than 500 grams of methamphetamine within 1000 feet of a protected location. At sentencing, the government filed motions under USSG § 5K1.1 and 18 U.S.C. § 3553(e) to reduce her sentence based on the provision of substantial assistance to authorities in the investigation or prosecution of other persons. A motion under § 5K1.1 authorizes the sentencing court to depart below the applicable advisory guideline range in determining the advisory guideline sentence, and a § 3553(e) motion permits the court to sentence below a statutory minimum.
See Melendez v. United States,
Prior to any reduction for assistance, the advisory guideline sentence for Williams was 120-121 months’ imprisonment, and the applicable statutory minimum was 120 months. The district court granted the substantial-assistance motions and announced that it would reduce the term of imprisonment to 78 months based on Williams’s assistance. The court then invoked § 3553(a) to reduce the sentence further, to a final term of 60 months’ imprisonment, based on Williams’s young age, medical history, drug use, and limited criminal history. The government does not challenge the district court’s reduction of the sentence to 78 months based on substantial assistance, but argues that the additional reduction to 60 months was legally impermissible, because the court relied on factors other than substantial assistance. This is a legal question that we review
de novo. United States v. Peterson,
We have said that a reduction in sentence based on § 3553(e) may be based only on assistance-related considerations,
e.g., United States v. Plaza,
To the extent the question remains open after Peterson (as the Plaza panel apparently thought it was), we conclude that the text of § 3553(e) provides a clear answer, and that Booker does not expand the district court’s authority to impose a sentence below a statutory minimum. Section 3553(e) provides:
(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 *1132 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.
Two aspects of the text are particularly instructive. First is the title, which states that the section provides only “limited authority” to impose a sentence below the statutory minimum. Congress evidently wanted statutory minimum sentences to be firmly enforced, subject only to carefully “limited” exceptions.
United States v. Ahlers,
Nothing in the reasoning of
Booker
expands the authority of a district court'to sentence below a statutory minimum. The Court’s remedial holding provided that to cure the constitutional infirmity, of the mandatory guidelines system, a district court is authorized to consider the factors set forth in § 3553(a), and to vary from the sentence otherwise indicated by
the sentencing guidelines.
But
Booker
did not question the constitutionality of statutory minimum sentences,
see United States v. Rojas-Coria,
In this case, the district court reduced Williams’s sentence below the statutory minimum in two increments' — one based on substantial assistance and one based on other factors. Because the second increment was impermissible for the reasons explained above, we vacate the sentence and remand for resentencing consistent with this opinion.
