James H. Matlock, a federal prisoner (# 90897-012), appeals the district court’s dismissal of his 28 U.S.C. § 2241 petition, which was purportedly filed pursuant to the “savings clause” of 28 U.S.C. § 2255. He attacked his 1991 sentence for distribution of cocaine base, arguing pursuant to Blakely v. Washington, 542 U.S. 296, 124 S.Ct. 2531, 159 L.Ed.2d 403 (2004), that the facts underlying his “career offender” enhancement, U.S.S.G. § 4B1.1, were neither submitted to a jury nor admitted, in violation of the Sixth Amendment.

Now relying on United States v. Booker, — U.S. -, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005), Matlock contends that his Booker claim falls within the savings clause in 28 U.S.C. § 2255. To proceed under the savings clause, the applicant must make the following three-part showing: (1) that his claim is based on a retroactively applicable Supreme Court decision; (2) the Supreme Court case “establishes that he was ‘actually innocent’ of the charges against him because the decision decriminalized the conduct for which he was convicted”; and (3) precedent foreclosed this claim at the time of the petitioner’s trial, appeal, or first § 2255 motion. Christopher v. Miles, 342 F.3d 378, 382 (5th Cir.) (citing Reyes-Requena v. United States, 243 F.3d 893, 904 (5th Cir. 2001)), cert. denied, 540 U.S. 1085, 124 S.Ct. 950, 157 L.Ed.2d 763 (2003).

Even assuming arguendo that the savings clause applies, Matlock has not stated a cognizable Booker claim. Determinations supporting a career-offender enhancement are questions of law, not fact, and do not implicate the Sixth Amendment. See United States v. Guevara, 408 F.3d 252, 261 (5th Cir. 2005). “Career offender status is not a ‘sentencing judge’s determination of a fact other than a prior conviction.’ ” Id. (citing Booker, 125 S.Ct. at 747 n. 1).

The judgment of the district court is AFFIRMED.
