Concepcion v. United States

Summary

The Court held that the First Step Act permits district courts deciding sentence-reduction motions to consider intervening changes in law or fact, including nonretroactive Guidelines amendments, post sentencing rehabilitation, and prison disciplinary records. Although courts must consider the parties' nonfrivolous arguments and explain their decisions, they retain discretion whether and how much to reduce a sentence. The Court reversed and remanded because the district court incorrectly believed it lacked authority to consider Concepcion's intervening circumstances.
