Craig Lamario Mosley, federal prisoner #21362-009, was convicted of conspiracy to possess a controlled substance with intent to distribute and received the statutory minimum sentence of 240 months. He now appeals the district court’s denial of his motion for a sentence reduction pursuant to 18 U.S.C. § 3582(c)(2) based on amendments to the Sentencing Guidelines governing crack cocaine. The Government has moved for summary affirmance or, in the alternative, for an extension of time to file a brief.

Because Mosley was sentenced to a mandatory statutory minimum, the district court lacked authority to grant a reduction under § 3582(c)(2). See United States v. Carter, 595 F.3d 575, 579-81 (5th Cir.2010); U.S.S.G. § 1B1.10, comment (n. 1(A)). Mosley’s reliance on the principles set forth in United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005), is without merit; Booker is inapplicable to a § 3582(c)(2) proceeding. See Dillon v. United States, — U.S. -, 130 S.Ct. 2683, 2691-94, 177 L.Ed.2d 271 (2010).

The motion for summary affirmance is GRANTED, the judgment of the district court is AFFIRMED, and the Government’s alternative motion for an extension of time is DENIED as unnecessary.
