Plain-English summary
Court to decide if federal judges must follow Sentencing Commission rules on ‘extraordinary and compelling’ sentence-re
The Supreme Court will decide whether district judges must apply the U.S. Sentencing Commission’s definitions when reducing federal prison sentences for “extraordinary and compelling reasons,” or whether judges may identify their own reasons. The case (Carter v. United States) was granted and argued in November 2025 and remains pending.
Why this matters
The Court’s answer will affect when and how federal prisoners can get shorter sentences. If judges are bound by the Sentencing Commission’s rules, relief could be limited to the circumstances the Commission listed. If judges have broader authority, more prisoners might obtain sentence reductions based on reasons outside the Commission’s guidance. The ruling will also shape the balance of authority between Congress, the Sentencing Commission, and federal judges.
Who may feel it

Key questions
- Does Congress’s delegation to the U.S. Sentencing Commission mean district courts must limit sentence reductions to circumstances the Commission defines as “extraordinary and compelling”?
