   ON REMAND FROM THE SUPREME COURT OF THE UNITED STATES

PER CURIAM:

This court affirmed the judgment of conviction and sentence of Arturo San Martin. United States v. San Martin, 117 Fed. Appx. 985 (5th Cir. Dec.17, 2004) (unpublished). The Supreme Court vacated and remanded for further consideration in light of United States v. Booker, — U.S. -, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005). We requested and received supplemental letter briefs addressing the impact of Booker.

San Martin contends that the district court illegally sentenced him pursuant to a mandatory Sentencing Guidelines regime, in violation of Booker. He concedes that such argument was raised for the first time on direct appeal and therefore is reviewable for plain error. See United States v. Mares, 402 F.3d 511, 520-21 (5th Cir.2005), cert. denied, — U.S.-, 126 S.Ct. 43, — L.Ed.2d - (2005). This court finds plain error when: (1) there was an error; (2) the error was clear and obvious; and (3) the error affected the defendant’s substantial rights. Id. at 520. Here, the first two prongs of the plain-error test are readily satisfied because it is clear after Booker that application of the Sentencing Guidelines in their mandatory form constitutes error that is plain. Id. at 521.

To satisfy the third prong of the plain-error test, San Martin must show that his “substantial rights” were affected. See United States v. Valenzuela-Quevedo, 407 F.3d 728, 733 (5th Cir.2005), cert. denied, — U.S. -, 126 S.Ct. 267, — L.Ed.2d - (2005). “[T]he pertinent question is whether [the appellant] demonstrated that the sentencing judge — sentencing under an advisory scheme rather than a mandatory one — would have reached a significantly different result.” Mares, 402 F.3d at 521. This question requires us to assess whether “there is [an] indication in the record from the sentencing judge’s remarks or otherwise that gives us any clue as to whether [ ]he would have reached a different conclusion” if sentencing under an advisory scheme. Id. at 522. San Martin has conceded that he cannot make such a showing under the Mares standard. To the extent that San Martin argues that the Booker error is a “structural” one that is not susceptible to a plain-error analysis, or that he alternatively contends that plain-error prejudice should be presumed, this court recently rejected such arguments. United States v. Martinez-Lugo, 411 F.3d 597, 601 (5th Cir.2005), cert. denied, — U.S. -, 126 S.Ct. 464, — L.Ed.2d-(2005).

Because nothing in the Supreme Court’s Booker decision requires us to change our prior affirmance of this case, we reinstate our judgment affirming San Martin’s conviction and sentence.

AFFIRMED. 
      
       Pursuant to 5th Cir. R. 47.5, the court has determined that this opinion should not be published and is not precedent except under the limited circumstances set forth in 5th Cir. R. 47.5.4.
