Court overturns appeals court ruling that granted new trial on a claim the defendant never raised
Impact2/10
What it does
The ruling reverses the Fourth Circuit's decision granting Jeremiah Sweeney a new trial, because the appeals court based its ruling on a legal claim Sweeney never raised. The Supreme Court sends the case back to the Fourth Circuit with instructions to rule only on the one claim Sweeney actually argued: that his trial lawyer was ineffective for not questioning the full jury after a juror made an unauthorized visit to the crime scene. On remand, the Fourth Circuit must apply the highly deferential standard required by federal law when reviewing state court criminal convictions.
Who benefits
State governments defending criminal convictions in federal habeas corpus proceedings (where a convicted person asks a federal court to review whether their imprisonment is lawful), who now cannot be ordered to retry a defendant on grounds the defendant never raised.
Who is affected
People convicted of crimes in state court who seek federal habeas corpus review, whose claims must be decided as they actually presented them — courts cannot independently devise new grounds for relief on their behalf.
Practical impact
The Fourth Circuit must now reconsider Sweeney's case and rule only on his ineffective-assistance-of-counsel claim, applying a very high bar for granting relief. More broadly, federal appeals courts are reminded that they may not grant habeas relief — or any relief — on legal theories that the parties themselves did not raise, even if the court believes those theories are meritorious.
Majority reasoning
The Court held that in the American adversarial legal system, it is the parties — not the judges — who define what issues are before the court; judges act as neutral referees of the disputes the parties bring to them. The Fourth Circuit broke this rule by granting Sweeney a new trial based on a sweeping "combination of extraordinary failures" theory that Sweeney himself never argued, and that the State therefore never had a chance to respond to. The Court found this "radical transformation" of Sweeney's single, narrow ineffective-assistance claim to be such a dramatic departure from the party-presentation principle that it constituted an abuse of discretion. On remand, the Fourth Circuit must evaluate the actual claim Sweeney raised — whether his lawyer was ineffective — under the doubly deferential standard that applies when a federal court reviews a state court's already-decided Strickland ruling, meaning relief is only available if every reasonable judge would agree that every reasonable lawyer would have acted differently.
Constitutional question
Did the Fourth Circuit Court of Appeals violate the principle of party presentation — the rule that courts decide only the claims parties actually raise — when it granted a convicted defendant a new trial based on a legal theory he never argued?
Precedent changed
Extended and applied United States v. Sineneng-Smith, 590 U.S. 371 (2020), which established that courts abuse their discretion when they "radically transform" a case by deciding issues the parties never raised.
