Gabriel Dewayne Antoine appeals the 60-month prison sentence imposed for his guilty plea conviction for possession with intent to distribute 17.48 grams of crack cocaine in violation of 21 U.S.C. § 841(a)(1).

Although § 841(b)(1)(B) no longer prescribes a five-year minimum sentence for offenses involving at least five but fewer than 28 grams of crack cocaine, see Fair Sentencing Act of 2010, Pub.L. No. 111— 220, 124 Stat. 2372, Antoine did not benefit from the amendment of the statute because he committed his offense, pleaded guilty, and was sentenced before the act’s August 3, 2010 effective date. See United States v. Doggins, 633 F.3d 379, 384 (5th Cir. 2011). Accordingly, former § 841(b)(1)(B)’s five-year minimum sentence for offenses involving at least five grams of crack cocaine applied in his case.

Antoine argues that the district court should have granted his motions for downward departure or variance below that mandatory minimum. We ordinarily lack authority to review a district court’s refusal to depart below a statutory minimum, but we may review de novo a district court’s decision that it lacked the authority to do so. United States v. James, 468 F.3d 245, 246-47 (5th Cir. 2006). The Government did not move for a downward departure based on substantial assistance under 18 U.S.C. § 3553(e), and Antoine was ineligible for a safety valve reduction under § 3553(f) because he had more than *431 one criminal history point. See § 3553(f)(1). Accordingly, the district court correctly determined that it lacked the authority to grant Antoine’s request for a downward departure. United States v. Krumnow, 476 F.3d 294, 297 (5th Cir. 2007). The district court also lacked the authority to grant Antoine’s motion for a nonguidelines sentence below the mandatory minimum. See United States v. Farias, 469 F.3d 393, 401 (5th Cir. 2006) (“[W]hatever result the Guidelines yield, the sentence cannot be less than the mandatory minimum.”); see also Kimbrough v. United States, 552 U.S. 85, 108, 128 S.Ct. 558, 169 L.Ed.2d 481 (2007) (stating that district courts remain constrained by statutory minimum penalties).

AFFIRMED.
