Whether the cause-and-prejudice rule applies when a state prisoner defaults a particular constitutional claim on direct appeal, rather than at trial.
Holding
Yes. A state procedural default on appeal is generally subject to the same cause-and-prejudice framework as a default at trial.
Reasoning
The Court had already indicated in Reed v. Ross that cause and prejudice applies to claims defaulted on appeal. Reed's recognition that a novel claim may supply cause for an appellate default would have been unnecessary if appellate defaults were outside the doctrine altogether.
Appellate procedural rules serve substantial state interests. They require defendants to present claims while the case is fresh, permit prompt review and possible retrial, promote efficient and accurate adjudication, and protect the finality of criminal judgments.
Those interests are impaired whether counsel omitted a claim intentionally or by mistake. An appellate omission deprives the state appellate court of the chance to correct the asserted trial error and undermines the State's ability to enforce its procedural rules. The Court therefore rejected a separate, more forgiving cause standard for appellate defaults.
