United States Court of Appeals Fifth Circuit F I L E D IN THE UNITED STATES COURT OF APPEALS FOR THE FIFTH CIRCUIT June 24, 2005 Charles R. Fulbruge III Clerk No. 03-41297 Summary Calendar UNITED STATES OF AMERICA, Plaintiff-Appellee, versus JOSE MANUEL GUERRERO, Defendant-Appellant. -------------------- Appeal from the United States District Court for the Southern District of Texas USDC No. 1:03-CR-172-3 -------------------- Before GARZA, DeMOSS and CLEMENT, Circuit Judges. PER CURIAM:* Jose Manuel Guerrero appeals the sentence imposed following his guilty-plea conviction for possession with intent to distribute more than 100 kilograms of marijuana. He argues that the district court erred in imposing his sentence based on the mandatory United States Sentencing Guidelines scheme held unconstitutional in United States v. Booker, 125 S. Ct. 738 (2005). Because the Government explicitly does not rely on the appeal waiver, we do not enforce it. United States v. Rhodes, * 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 R. 47.5, the court has determined that this opinion should not be published and is not precedent except under the limited circumstances set forth in 5TH CIR.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. No. 03-41297 -2- 253 F.3d 800, 804 (5th Cir. 2001). Because Guerrero did not raise this issue in the district court, review is limited to plain error. See United States v. Mares, 402 F.3d 511, 520 (5th Cir. 2005), petition for cert. filed, No. 04-9517 (U.S. Mar. 31, 2005). The district court’s application of the mandatory Guidelines sentencing scheme is error that is plain. Id. However, Guerrero has not met his burden to establish that the error affected his substantial rights as he has not shown that the sentencing judge would have reached a significantly different result under an advisory sentencing scheme rather than a mandatory one. Id. at 521. Therefore, Guerrero has not shown that the district court’s imposition of his sentence constituted reversible plain error. Accordingly, Guerrero’s sentence is AFFIRMED.
