What it's about

This case involved two Arizona death row prisoners who argued in federal habeas proceedings that their trial lawyers were ineffective, even though those claims had not been properly developed in state court. The Supreme Court considered whether a federal court may look at new evidence outside the state-court record when the procedural default is excused because the prisoner’s state postconviction lawyer was ineffective.

Question presented

Does application of the equitable rule this Court announced in Martinez v. Ryan render 28 U.S.C. § 2254(e)(2) inapplicable to a federal court's merits review of a claim for habeas relief?
