Standard: AEDPA deferential standard under 28 U. S. C. Section 2254(d)(1)
Vote: The Court granted certiorari and reversed the Fourth Circuit's judgment.

Klein v. Martin

January 26, 2026 ·25-51 ·Panel Decision ·Per Curiam · By James Taylor

The Supreme Court reversed the Fourth Circuit, holding that the state court's denial of habeas relief did not contravene clearly established federal law. The Court found the undisclosed forensic report was not material under Brady v. Maryland given the strength of the other evidence.

Background

Respondent Charles Brandon Martin was convicted in Maryland for the attempted murder of his girlfriend. He sought post-conviction relief and federal habeas corpus, arguing the State failed to disclose a forensic report showing his laptop had not been used to research silencers. The District Court granted habeas relief, and the Fourth Circuit affirmed, but the Supreme Court reversed.

The court’s reasoning

The Court held that the state appellate court’s decision was neither contrary to nor an unreasonable application of clearly established federal law. The Fourth Circuit contravened AEDPA by second-guessing the state court’s application of the Brady materiality test and by concluding that no fair-minded jurist could find the evidence immaterial despite strong support for the state court’s conclusion.

What it means going forward

Federal courts must strictly adhere to the highly deferential AEDPA standard and cannot impose their own opinion-writing standards or re-evaluate state court factual determinations unless the decision is objectively unreasonable.
