Lawrence Holman appeals the denial of his 18 U.S.C. § 3582(c)(2) motion for a sentence reduction. That motion was based on Amendment 706 to the Sentencing Guidelines, which reduced base offense levels applicable to crack cocaine. Holman contends that the district court erred by applying as mandatory an application note prohibiting a reduction where the defendant was sentenced pursuant to the revocation of his supervised release.

“We review de novo a district court’s conclusions about the scope of its legal authority under 18 U.S.C. § 3582(c)(2).” United States v. James, 548 F.3d 983, 984 (11th Cir. 2008). A district court may modify a term of imprisonment in the case of a defendant who was sentenced to a term of imprisonment based on a sentencing range that has subsequently been lowered by the Sentencing Commission. 18 U.S.C. § 3582(c)(2). Any reduction, however, must be “consistent with the applicable policy statements issued by the Sentencing Commission.” Id.

The commentary to the applicable policy statements, found in U.S.S.G. § 1B1.10, instructs as follows: “Only a term of imprisonment imposed as part of the original sentence is authorized to be reduced under this section. This section does not authorize a reduction in the term of imprisonment imposed upon revocation of supervised release.” U.S.S.G. § 1B1.10, cmt. 4(A) (Nov. 2008). This commentary is binding, so long as it does not violate the Constitution or a federal statute, and is not plainly erroneous or inconsistent with the guidelines. Cook v. Wiley, 208 F.3d 1314, 1322 n. 12 (11th Cir. 2000). It is none of those things.

We recently held that United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005), does not apply to § 3582(c)(2) proceedings, and the district court is bound by the limitations imposed by U.S.S.G. § 1B1.10. See United States v. Melvin, 556 F.3d 1190, 1192 (11th Cir. 2009) (holding that Booker does not “prohibit the limitations on a judge’s discretion in reducing a sentence imposed by § 3582(c)(2) and the applicable policy-statement by the Sentencing Commission”). Accordingly, the district court *847 does not have the authority to reduce a sentence imposed upon revocation of supervised release.

AFFIRMED.
