- What it's about
The Supreme Court held that Joe Fernandez could not use the federal compassionate-release law to challenge the validity of his conviction or seek a shorter sentence based on claimed innocence. Such challenges must be brought under the federal habeas statute, 28 U.S.C. §2255, and alleged invalidity of a conviction is not an "extraordinary and compelling" reason for compassionate release; the United States prevailed.
Question presented
Can a federal prisoner use the compassionate release law to get their sentence reduced based on claims that they might be innocent or that their sentence is unfair, even though these same claims would normally have to be raised through habeas corpus?

Decision
What the Court decided
Federal prisoners must use Section 2255, not compassionate release, to argue that their convictions are invalid.
Impact
Federal prisoners challenging a conviction’s validity must use §2255, the habeas corpus statute (law for post-sentencing challenges). They cannot use compassionate release for doubts about conviction validity. For example, Fernandez’s innocence-related arguments could not support compassionate release. The ruling preserves §2255’s one-year deadline and general one-attempt rule for these challenges. Compassionate release remains focused on personal circumstances, including terminal illness, advanced age, and rehabilitation.

Briefing
What it's about
The Supreme Court ruled that federal prisoners cannot use compassionate release to challenge whether their convictions are legally valid. Those challenges must go through Section 2255, a federal procedure for prisoners challenging convictions or sentences after trial.
Vote
Justice Barrett wrote the 8–1 opinion, joined by Chief Justice Roberts and Justices Thomas, Alito, Kagan, Gorsuch, and Kavanaugh; Justice Sotomayor concurred; Justice Jackson dissented.
Justice Amy Coney Barrett wrote the Court's 8-1 opinion affirming the Second Circuit. Justice Sonia Sotomayor concurred, and Justice Ketanji Brown Jackson dissented.
““The supposed invalidity of a conviction is not among the ‘extraordinary and compelling reasons’ that justify compassionate release.””
Impact
Federal prisoners seeking a shorter sentence cannot use compassionate release as a substitute for a Section 2255 challenge. For example, a prisoner claiming a conviction was invalid must use the Section 2255 process instead.
What's next
Lower federal courts will apply this rule when prisoners seek compassionate release based on attacks on their convictions. Prisoners pursuing those claims must instead use the Section 2255 process.
What did the Supreme Court rule in Fernandez v. United States?
The Court said compassionate release cannot be used to challenge a conviction's validity. Such claims must proceed under Section 2255.
Who is affected by the Fernandez decision?
Federal prisoners seeking sentence reductions based on claims their convictions are invalid are affected. They must use Section 2255 rather than compassionate release.
What happens next after Fernandez v. United States?
Lower courts must follow the decision in compassionate-release cases. Prisoners challenging convictions must pursue the separate Section 2255 process.
