No. 25-52Nov 24, 2025LawReversed and remanded

The question

Whether the Fourth Circuit violated the party-presentation principle by granting a habeas petitioner a new trial on a constitutional claim he never raised.

Clark v. Sweeney

What the Court decided

The Court reversed the Fourth Circuit and remanded. Sweeney sought federal habeas relief on a single claim, that his trial counsel was ineffective under Strickland for not seeking to voir dire the entire jury after one juror made an unauthorized crime-scene visit. The Fourth Circuit instead ordered a new trial on Confrontation Clause and impartial-jury grounds that Sweeney never asserted and the State never had a chance to address. The Court held that granting relief on an unraised claim departed so far from the principle of party presentation as to be an abuse of discretion, and directed the Fourth Circuit on remand to address the ineffective-assistance claim Sweeney actually raised.

Delivered by the Court

The Court held that the Fourth Circuit departed from the principle of party presentation by granting Sweeney a new trial on Confrontation Clause and impartial-jury grounds he never raised, rather than deciding the ineffective-assistance claim he actually asserted. Under the adversarial system the parties frame the issues and the court acts as a neutral arbiter of matters the parties present. Transforming Sweeney's ineffective-assistance claim into constitutional theories the State never had a chance to address was an abuse of discretion. On remand the Fourth Circuit must analyze the ineffective-assistance claim Sweeney raised.
