Melvin DeWayne Smith, federal prisoner # 66584-079, appeals the district court’s dismissal of his 28 U.S.C. § 2241 petition challenging his guilty-plea conviction and sentence for engaging in a continuing criminal enterprise to possess with intent to distribute controlled substances. Smith’s motion for supplementation of brief is granted.

Smith argues that his sentence violated his Sixth Amendment rights as set forth in United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005), because it was enhanced based upon facts not alleged in the indictment, mentioned in the plea agreement, admitted by him, or proven to a jury. The decision in Booker does not apply retroactively to cases on collateral review, and a Booker claim does not satisfy the test for filing a § 2241 petition under the savings clause of 28 U.S.C. § 2255. Padilla v. United States, 416 F.3d 424, 427 (5th Cir. 2005).

For the first time on appeal, Smith argues that his conviction was improper under Richardson v. United States, 526 U.S. 813, 119 S.Ct. 1707, 143 L.Ed.2d 985 (1999), and that this claim may be brought in a § 2241 petition under the savings clause of § 2255. This newly raised legal claim is not reviewable for the first time on appeal. See Leverette v. Louisville Ladder Co., 183 F.3d 339, 342 (5th Cir. 1999). Smith raised his Richardson claim in this court in his appeal from the denial of his previous § 2241 petition. We warn Smith that filing future repetitive appeals will subject him to sanctions.

AFFIRMED; MOTION FOR SUPPLEMENTATION OF BRIEF GRANTED; SANCTION WARNING ISSUED.
