Whether appellate courts may require extraordinary circumstances or proportional justifications for a sentence that substantially varies from the advisory Guidelines range.
Holding
No. Courts of appeals must review every sentence—inside, just outside, or substantially outside the Guidelines range—under the same deferential abuse-of-discretion standard.
Reasoning
Booker made the Sentencing Guidelines advisory and replaced de novo review of departures with review for reasonableness. That reasonableness review incorporates the familiar abuse-of-discretion standard; it does not authorize a heightened appellate standard simply because the district court selected a non-Guidelines sentence.
The Guidelines remain the required starting point and initial benchmark because they promote national consistency and reflect the Sentencing Commission's accumulated sentencing experience. A sentencing judge must correctly calculate the range, hear the parties' arguments, consider every relevant factor in 18 U.S.C. § 3553(a), make an individualized assessment, and adequately explain the chosen sentence.
A major variance ordinarily calls for a more significant justification than a minor variance. But requiring “extraordinary” circumstances, or using a rigid formula that measures a variance by percentage, comes too close to an impermissible presumption that outside-Guidelines sentences are unreasonable.
Percentage-based review is especially misleading when the applicable range is low: probation is always described as a 100 percent reduction from a prison term, regardless of whether the Guidelines minimum is one month or many years. It also ignores the real restraints on liberty imposed by probation, including reporting, travel and employment restrictions, home visits, and drug testing.
An appellate court must first identify significant procedural error, such as a miscalculated Guidelines range, treating the Guidelines as mandatory, failure to consider § 3553(a), reliance on clearly erroneous facts, or an inadequate explanation. If the procedure was sound, the court then reviews substantive reasonableness under abuse of discretion, considering the totality of the circumstances and giving due deference to the district judge's assessment that the § 3553(a) factors justify the variance.
District judges have an institutional advantage in sentencing because they see and hear the evidence, evaluate credibility, and have fuller familiarity with the individual defendant and case. An appellate court may not reverse merely because it would have selected a different sentence.
