What the Court decided
Holding
1. This Court has jurisdiction to review the OCCA’s judgment. The independent and adequate state ground doctrine precludes the Court from considering a federal question if the state court’s decision rests on an independent and adequate state law ground. OCCA’s application of the PCPA was not such a ground, because the OCCA’s decision to apply the PCPA depended on its antecedent rejection of the attorney Cite as: 604 U. S. ____ (2025) 3 Syllabus general’s confession of a Napue error, which was based solely on federal law. The OCCA held that the confession could not overcome the PCPA’s limitations because it lacked a basis in law or fact, specifically finding no Napue error. 529 P. 3d 218, reversed and remanded.
