Supreme Court of the United States

Klein v. Martin

January 26, 2026

Summary

The Court granted the State’s petition for a writ of certiorari, reversed the Fourth Circuit, and held that the Maryland appellate court correctly applied the Brady materiality standard, that the undisclosed forensic report was not material, and that under AEDPA the federal courts must deny habeas relief because the state court’s decision was not contrary to or an unreasonable application of clearly established federal law.
