Federal Sentencing: Guidelines, the Presentence Report, and 18 U.S.C. § 3553(a)

Federal sentencing is a two-part calculation. The U.S. Sentencing Commission promulgates guidelines under 28 U.S.C. § 994 for use by the sentencing court; the court then imposes a sentence under the factors of 18 U.S.C. § 3553(a). The guidelines are advisory, but the court must calculate them correctly, and the resulting range frames the sentence.

The guidelines and the Commission

28 U.S.C. § 994 directs the Sentencing Commission to promulgate and distribute guidelines “for use of a sentencing court in determining the sentence to be imposed in a criminal case.” The guidelines score the offense conduct, the defendant's role, and criminal history into an advisory range.

The § 3553(a) factors

18 U.S.C. § 3553(a) requires the court to impose a sentence sufficient, but not greater than necessary, to comply with the purposes of sentencing. The court must consider the nature and circumstances of the offense and the history and characteristics of the defendant, plus the need for the sentence to reflect the seriousness of the offense, afford adequate deterrence, protect the public, and provide needed training, medical care, or correctional treatment.

The presentence report

Before sentencing, a probation officer prepares a presentence report calculating the guideline range. Objections to the report are resolved before the hearing, and the final range — along with any departures or variances under § 3553(a) — determines the sentence the court imposes.
