Andre Mills appeals his guilty plea conviction for aiding and abetting the possession of more than five grams of cocaine base with intent to distribute. Mills argues that 21 U.S.C. §§ 841(a) and (b) were rendered facially unconstitutional by Apprendi v. New Jersey, 530 U.S. 466, 490, 120 S.Ct. 2348, 147 L.Ed.2d 435 (2000). Mills concedes that his argument is foreclosed by our opinion in United States v. Slaughter, 238 F.3d 580, 581-82 (5th Cir. 2000) (revised opinion), cert. denied, 532 U.S. 1045, 121 S.Ct. 2015, 149 L.Ed.2d 1015 (2001), which rejected a broad Apprendi-based attack on the constitutionality of that statute. He raises the issue only to preserve it for Supreme Court review. A panel of this court cannot overrule a *400prior panel’s decision in the absence of an intervening contrary or superseding decision by this court sitting en banc or by the United States Supreme Court. Burge v. Parish of St. Tammany, 187 F.3d 452, 466 (5th Cir. 1999). No such decision overruling Slaughter exists. Accordingly, Mills’s argument is foreclosed.

AFFIRMED.
