USCA4 Appeal: 25-1223 Doc: 21 Filed: 04/30/2026 Pg: 3 of 3

PER CURIAM: Mark Marvin, a nonparty to the underlying litigation, seeks to appeal the district court’s order returning—without docketing—his pro se “Notice of Branzburg v. Hayes Motion,” which the court construed as an unauthorized amicus brief. The court advised Marvin that he had not sought leave to file an amicus brief nor had he moved to intervene.

This court may exercise jurisdiction only over final orders, 28 U.S.C. § 1291, and certain interlocutory and collateral orders, 28 U.S.C. § 1292; Fed. R. Civ. P. 54(b); Cohen v. Beneficial Indus. Loan Corp., 337 U.S. 541, 545-46 (1949). The order Marvin seeks to appeal is neither a final order nor an appealable interlocutory or collateral order.

Accordingly, we dismiss the appeal for lack of jurisdiction. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before this court and argument would not aid the decisional process.

DISMISSED
