Briefing
What it's about
Waidla asks whether an appellate court can replace a panel member after publishing a decision, rehear the appeal, and change the result solely because that member withdrew. The case comes from a Ninth Circuit capital habeas appeal involving a claim that trial counsel was constitutionally ineffective at the penalty phase.
Argument
The Court has not scheduled oral argument, and no Supreme Court decision is available. The certiorari petition (a request for Supreme Court review) was submitted to Justice Kagan.
Impact
The answer could affect people whose appeals have already been decided, including prisoners challenging criminal convictions or sentences. For example, a litigant could face a changed appellate result after a judge leaves the original panel.
What is at stake in Waidla v. Pierce?
The case concerns whether a published appellate decision can be reconsidered and reversed after one original panel member withdraws.
Who could be affected by the Supreme Court's action?
People with appeals already decided could be affected, including prisoners challenging convictions or sentences. Appellate courts could also face limits on replacing panel members.
What happens next in Waidla v. Pierce?
The Court may schedule oral argument or take another action on Waidla's petition for review. No decision timing has been announced.
