Luis Pimentel-Hillan appeals his guilty-plea conviction and sentence for illegal reentry, in violation of 8 U.S.C. § 1326. Pimentel asserts his sentence is illegal under United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005), because it was imposed pursuant to a mandatory application of the federal Sentencing Guidelines.
The erroneous application of the Guidelines as mandatory is technically a Fanfan error. United States v. Martinez-Lugo, *460411 F.3d 597, 600 (5th Cir.), cert. denied, — U.S. -, 126 S.Ct. 464, 163 L.Ed.2d 352 (2005); see Booker, 125 S.Ct. at 750, 768-69. Such error is not structural. Martinez-Lugo, 411 F.3d at 601.
The Government concedes Pimentel preserved his Fanfan claim for appeal. The Government fails to meet its burden of proving the sentence was harmless beyond a reasonable doubt because it fails to cite to any record evidence showing the district court would have imposed the same sentence under an advisory guidelines scheme. See United States v. Garza, 429 F.3d 165, 171 (5th Cir.2005), petition for cert. filed,{No. 05-8843) (23 Jan. 2006); United States v. Walters, 418 F.3d 461, 464 (5th Cir.2005). We therefore vacate Pimentel’s sentence and remand the case for resentencing in accordance with Booker.
Pimentel also maintains the enhancement provisions in § 1326(b) are unconstitutional. As he concedes, this contention is foreclosed by Almendarez-Torres v. United States, 523 U.S. 224, 118 S.Ct. 1219, 140 L.Ed.2d 350 (1998), which this court must follow “unless and until the Supreme Court itself determines to overrule it”. United States v. Izaguirre-Flores, 405 F.3d 270, 277-78 (5th Cir.) (quotation marks omitted), cert. denied, — U.S. -, 126 S.Ct. 253, 163 L.Ed.2d 231 (2005). He raises the issue to preserve it for further review.
CONVICTION AFFIRMED; SENTENCE VACATED; REMANDED FOR RESENTENCING
