What standard governs appellate review of a federal sentence for substantive reasonableness after Booker, Rita, Gall, and Kimbrough?
Holding
A court of appeals reviews substantive reasonableness for abuse of discretion, but that deferential review permits the court to vacate a sentence when the district court unreasonably weighs the § 3553(a) factors and reaches a sentence outside the range of reasonable outcomes.
Reasoning
The court explained that Booker preserved appellate sentencing review and made the Guidelines advisory, not irrelevant. Under Rita and Gall, appellate courts must correct substantively unreasonable sentences while giving due deference to a sentencing judge's superior position to evaluate the individual case.
An abuse of discretion may occur when a sentencing court ignores a relevant factor entitled to substantial weight, gives substantial weight to an improper or irrelevant consideration, or commits a clear error of judgment in balancing proper considerations. Thus, substantive review is not confined to checking for procedural mistakes or clearly erroneous historical facts.
The court rejected the view that appellate courts may never review the weight assigned to § 3553(a) factors. Gall itself assessed whether the district court reasonably gave substantial weight to the defendant's voluntary withdrawal from a conspiracy and post-offense rehabilitation. Meaningful substantive review necessarily examines whether the factors can bear the weight assigned to them, though it does not authorize reversal simply because an appellate court would have imposed a different sentence.
