What it's about
The Court refused to hear his case (denied review), so it did not decide those questions.
The dispute concerned whether a later change in law can excuse a person for not raising a claim earlier when challenging a federal conviction.
Question presented
1. Whether this Court’s decision in Ruan v. United States, 597 U.S. 450 (2022) constitutes a sufficiently “novel” intervening change in law to constitute “cause” excusing a procedural default under 28 U.S.C. § 2255. 2. Whether this Court’s holding in Reed v. Ross, 468 U.S. 1 (1984)—that a decision overturning a unanimous or nearly unanimous circuit interpretation of a federal criminal statute, where that interpretation was based on, if not compelled by, this Court’s own precedent, constitutes “cause” excusing procedural default—survived this Court’s later decision in Bousley v. United States, 523 U.S. 614 (1998).
