George R. Shelton seeks to appeal the magistrate judge’s report and recommendation. This court may exercise jurisdic*580tion only over final orders, 28 U.S.C. § 1291 (2000), and certain interlocutory and collateral orders, 28 U.S.C. § 1292 (2000); Fed.R.Civ.P. 54(b); Cohen v. Beneficial Indus. Loan Corp., 337 U.S. 541, 69 S.Ct. 1221, 93 L.Ed. 1528 (1949). The order Shelton seeks to appeal is neither a final order nor an appealable interlocutory or collateral order. Accordingly, we deny a certificate of appealability and 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 the court and argument would not aid the decisional process.
DISMISSED.
