Jose Antonio Doyharzabal appeals pro se the district court’s denial of his motion for reconsideration of its order denying his petition for a writ of audita querela. 1 He contends that a writ of audita querela is the only remaining avenue by which he can challenge the constitutionality of his sentence and seek retroactive application of United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005).

We “review de novo the question of whether a prisoner may challenge his sentence by filing a motion for a writ of audita querela.” United States v. Holt, 417 F.3d 1172, 1174 (11th Cir. 2005) (per curiam).

Audita querela is “an ancient writ used to attack the enforcement of a judgment after it was rendered.” Id. Although we have noted that “federal courts may properly fill the interstices of the federal post-conviction remedial framework through remedies available at common law,” id. at 1175 (quotation omitted), a writ of audita querela may not be granted where the “relief [sought] is cognizable under [28 U.S.C.] § 2255.” Id. Here the relief that Doyharzabal seeks — vacating his sentence as unconstitutional — falls within the scope of § 2255. 2 Therefore, he cannot seek relief from his sentence under a writ of audita querela. The district court properly denied his motion.

AFFIRMED.
