Concepcion v. United States

Background

Carlos Concepcion, a man convicted in 2007 of distributing crack cocaine, was sentenced in 2009 to 228 months in prison after his sentence was raised because he was treated as a career offender. Congress later changed the rules for crack-cocaine penalties in 2010 and then passed the First Step Act in 2018 allowing judges to reduce old crack sentences as if the 2010 changes had been in effect. Concepcion asked a judge in 2019 for a shorter sentence, arguing the new law and later legal developments would lower his guidelines and that he had rehabilitated in prison. The District Court refused to consider those later changes or his rehabilitation, and the Court of Appeals affirmed in a split decision.

Reasoning

The Supreme Court held that courts historically have wide discretion to consider any relevant information about a person when setting or modifying a sentence. Nothing in the First Step Act limits judges from weighing intervening changes in law or fact. The Act requires judges to calculate the sentence as if the 2010 law applied at the time of the offense, but it does not forbid looking at prison conduct, later guideline changes, or vacated prior convictions when deciding whether and by how much to reduce a sentence. Judges must explain they considered the parties' nonfrivolous arguments, but they are not required to grant relief.

Real world impact

Lower courts may now review a wider set of materials, such as post-sentencing rehabilitation records or later legal rulings, when deciding First Step Act motions. The decision does not guarantee reductions; judges retain discretion and appellate review is deferential. The ruling resolves a disagreement among federal appeals courts about what judges may consider.

Dissents or concurrances

A dissent argued the First Step Act authorizes reductions only based on the 2010 changes and warned that allowing broader consideration creates uneven outcomes across cases.
