Jose Maria Buitron-Garcia appeals his guilty plea conviction for possession with intent to distribute 100 kilograms or more, but not less than 1,000 kilograms, of marihuana. He argues that the sentencing provision of 21 U.S.C. § 841(b)(1)(B) is unconstitutional in light of Apprendi v. New Jersey, 530 U.S. 466, 490, 120 S.Ct. 2348, 147 L.Ed.2d 435 (2000). BuitronGarcia concedes that his argument is foreclosed by our opinion in United States v. Slaughter, 238 F.3d 580, 581-82 (5th Cir. 2000). He raises the issue only to preserve it for Supreme Court review.

A panel of this court cannot overrule a prior 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, Buitron-Gareia’s argument is foreclosed, and the judgment of the district court is AFFIRMED.

The Government has moved for a summary affirmance in lieu of filing an appellee’s brief. In its motion, the Government asks that an appellee’s brief not be required. The motion is GRANTED.

AFFIRMED; MOTION GRANTED.
