Correction and Reduction of Sentence by the District Court. Following a successful appeal of the sentence, the district court is required to correct the sentence in accordance with the appellate court's findings and in a manner consistent with 18 U.S.C. § 3553. At resentencing, the district court may consider evidence of a defendant's rehabilitation since his or her prior sentencing, and such evidence may support a downward variance from the advisory Guidelines range. Rule 35 of the Federal Rules of Criminal Procedure permits a district court to reduce a sentence to reflect the defendant's subsequent substantial assistance in the investigation or prosecution of another criminal. Such reductions may fall below the statutory minimum, and may be granted only on motion by the government. A prison sentence also may be reduced for extraordinary or compelling reasons, but only on a motion by the Bureau of Prisons. A defendant or the court may move for a sentence reduction if the Sentencing Commission subsequently lowers the sentencing range for an offense and makes the amendment retroactively applicable.
