Concepcion v. United States

Background

Carlos Concepcion pleaded guilty in 2007 to distributing crack cocaine and was sentenced in 2009 to 228 months. At his original sentencing he qualified as a career offender, which raised his Guidelines range. Congress later passed the Fair Sentencing Act in 2010 (raising the crack threshold from 5 to 28 grams) and in 2018 enacted the First Step Act to let some prisoners seek reduced sentences “as if” the Fair Sentencing Act had applied earlier.

Reasoning

The Court addressed whether district judges deciding First Step Act motions may consider intervening changes of law (for example, Guideline changes) or intervening facts (for example, prison behavior or rehabilitation). The majority explained that federal sentencing tradition gives judges broad discretion to consider the whole person and all relevant information unless Congress or the Constitution expressly limits that inquiry. The First Step Act’s text did not bar consideration of intervening changes, so judges may weigh such evidence when exercising their discretion to reduce a sentence.

Real world impact

Lower courts must consider nonfrivolous arguments about post-sentencing rehabilitation and later legal developments when ruling on First Step Act motions. The decision does not force reductions; judges still have discretion and must explain they considered the parties’ arguments. Many defendants sentenced under the old crack rules may now seek relief with broader evidence.

Dissents or concurrances

A dissent argued the statute authorizes reductions only by applying the Fair Sentencing Act’s changes and warned that allowing other intervening changes could create unequal results across defendants and courts.
