Whether Booker requires courts in §3582(c)(2) sentence-reduction proceedings to treat USSG §1B1.10’s restriction on below-range reductions as advisory.
Holding
No. Booker’s constitutional and remedial holdings do not apply to §3582(c)(2) proceedings, so §1B1.10 remains binding in those proceedings.
Reasoning
Section 3582(c)(2) authorizes a limited modification of an otherwise final prison sentence, not a plenary resentencing. Its text permits a court to reduce a sentence only when the defendant’s Guidelines range was later lowered by the Sentencing Commission and only when the reduction is consistent with the Commission’s applicable policy statements.
Congress assigned the Sentencing Commission a central role in retroactive sentence reductions. Under 28 U.S.C. §994(u), the Commission decides whether a Guidelines amendment will apply retroactively and by what amount affected sentences may be reduced. Section 3582(c)(2) expressly incorporates the Commission’s policy statements as a condition on judicial authority to grant relief.
The statute creates a two-step inquiry. First, the court must determine the reduction authorized by §1B1.10: it substitutes the retroactive amendment for the old provision while leaving all other Guidelines decisions unchanged. Second, the court considers the applicable §3553(a) factors to decide whether the authorized reduction is warranted in whole or in part.
At the first step, §1B1.10 generally bars a reduction below the bottom of the amended Guidelines range. A court may go comparably below that range only when the original sentence was itself below the original range. Because Dillon originally received a bottom-of-the-range sentence, the District Court could reduce his drug sentence only to the bottom of the amended range.
Booker addressed the Sixth Amendment problem created when judge-found facts increased a defendant’s mandatory sentencing range. A §3582(c)(2) proceeding does not increase the defendant’s punishment or create a new sentencing range based on judicial factfinding; it merely gives a court limited discretion to reduce an already-final sentence. Thus, adherence to §1B1.10 does not invade the jury’s constitutional factfinding role.
Booker’s remedial rule also did not require advisory treatment here. The Court rejected a partial Booker remedy because it would have treated the Guidelines differently in otherwise similar sentencing proceedings. Sentence-modification proceedings under §3582(c)(2), however, are materially different from original sentencings: they are a congressional act of lenity, apply only to a limited class of prisoners, and operate within limits Congress delegated to the Commission.
