Jerry J. Anderson, a federal prisoner, appeals the district court’s order accepting the recommendation of the magistrate judge and denying relief on his petition filed under 28 U.S.C. § 2241 (2000). As the district court recognized, the fact that Anderson’s petition could not proceed under 28 U.S.C. § 2255 (2000) does not necessarily render that section inadequate so as to permit Anderson to proceed under § 2241. See In re Vial, 115 F.3d 1192, 1194 n. 5 (4th Cir. 1997). Moreover, the decision in Apprendi v. New Jersey, 530 U.S. 466, 120 S.Ct. 2348, 147 L.Ed.2d 435 (2000), upon which Anderson’s claim is based, is not retroactively applicable in § 2241 petitions. See San-Miquel v. Dove, 291 F.3d 257, 260-61 & n. 2 (4th Cir.), cert. denied, 537 U.S. 938, 123 S.Ct. 46, 154 L.Ed.2d 242 (2002). Accordingly, we affirm the district court’s decision. 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.

AFFIRMED
