UNITED STATES of America, Plaintiff-Appellee, v. Oscar SERRANO-DOMINGUEZ, Defendant-Appellant, 406 F.3d 1221

McCONNELL, Circuit Judge. The defendant, Oscar Serrano-Dominguez, appeals his sentence of 33 months imprisonment for illegally reentering the United States in violation of .8 U.S.C. § 1326. Mr. Serrano-Dominguez argues that the use of the Federal Sentencing Guidelines (“Guidelines”) to sentence him is unconstitutional in light of Blakely v. Washington, — U.S. —, 124 S.Ct. 2531, 159 L.Ed.2d 403 (2004). We evaluate this claim now that the Supreme Court has issued its decision in United States v. Booker, — U.S. —, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005), and AFFIRM Mr. Serrano-Dominguez’s sentence. I. Mr.

Serrano-Dominguez was found in the United States on or about March 8, 2004. The indictment alleged that he illegally reentered the country after he was convicted of an aggravated felony and deported. Mr. Serrano-Dominguez entered into a plea agreement, in which he admitted the conduct alleged in the indictment, and the government agreed to recommend a three-level decrease in his offense level for his acceptance of responsibility. The plea agreement stipulated that Mr. Serrano-Dominguez would be sentenced through the application of the Guidelines.

The probation officer assigned a base offense level of 8, see U.S.S.G. § 2L1.2(a) (2003), and applied an 8-level enhancement because Mr. Serrano-Dominguez had a prior conviction for an aggravated felony. See U.S.S.G. § 2L1.2(b)(1)(C). Mr. Serrano-Dominguez received a three-level reduction for acceptance of responsibility, U.S.S.G. § 3E1.1. Based on his total offense level of 13 and a criminal history category of VI, the presentence report determined that the permissible range for the sentence was 33 to 41 months. See U.S.S.G. ch. 5 pt. A. Prior to sentencing Mr.

Serrano-Dominguez filed a motion seeking to declare the Guidelines as a whole unconstitutional pursuant to Blakely. The district court denied the motion. However, before sentencing, the district court directed Mr. Serrano-Dominguez and his counsel to discuss his plea in light of Blakely. After this discussion, he signed a statement reaffirming the plea agreement with the knowledge that he had a Sixth Amendment right to have a jury find any sentence enhancing facts by a reasonable doubt. Mr. Serrano-Dominguez testified under oath that he accepted the provisions in the written statement.

However, the signed statement reserved the right “to challenge the constitutionality of the U.S. Sentencing Guidelines.” R. Vol. I Doc. 33 ¶ 10. After establishing this waiver, the district court sentenced Mr. Serrano-Dominguez, under the Guidelines, to 33 months imprisonment. In addition, the district court imposed an alternative sentence of 33 months imprisonment in the event the Supreme Court changed the status of the Guidelines pursuant to Blakely. II. Mr. Serrano-Dominguez appeals the district court’s denial of his motion to declare the Sentencing Guidelines unconstitutional. In United States v.

Labastida-Segura, we concluded that a similar appeal was sufficient to preserve a potential Sixth Amendment error pursuant to Labastida-Segura, 396 F.3d 1140, 1142-43 (10th Cir.2005). Where a defendant preserves a potential Booker error, we will remand if the error was not harmless, i.e., the error did not affect the defendant’s substantial rights. See id.; Fed.R.Crim.P. 52(a). There are two types of error under Booker: constitutional error and non-constitutional error. See United States v. Gonzalez-Huerta, 403 F.3d 727, 731 (10th Cir.2005) (en banc).

Constitutional Booker error occurs when a judge-found fact (other than a prior conviction) increases a defendant’s sentence beyond the maximum authorized by a jury’s verdict or a plea of guilty through the application of mandatory guidelines. Booker, 125 S.Ct. at 756. Non-constitutional error is a product of the remedial opinion in Booker, which severed the statutory provision requiring mandatory application of the Sentencing Guidelines in most cases. Id. at 764 (severing 18 U.S.C. § 3553(b)(1)).

Severing this provision effectively rendered the Guidelines advisory, although sentencing courts must consult both the Guidelines and the factors listed in 18 U.S.C. 3553(a), and appellate courts will reverse any sentences that are unreasonable. Id. at 767. Any sentence imposed through mandatory application of the Sentencing Guidelines, even where there is no Sixth Amendment violation, is erroneous. Gonzalez-Huerta, 403 F.3d at 731. This case involves only non-constitutional error. In his guilty plea, Mr.

Serrano-Dominguez admitted all the facts necessary to authorize his sentence, so his sentence does not implicate the Sixth Amendment. However, the district court applied a sentence at the bottom of the then-mandatory range provided by the Sentencing Guidelines. Accordingly, there was an error in Mr. Serrano-Dominguez’s sentence, and we must determine whether ■ or not this error was harmless. In Labastida-Segura, the defendant, like Mr. Serrano-Dominguez, admitted all the facts required to support his sentence and received a sentence at the bottom of the Guidelines range. 396 F.3d at 1142.

We framed the harmless error analysis by asking whether the non-constitutional Booker error affected the sentence the defendant would receive under the post-Booker framework of consulting advisory Guidelines, the § 3553(

a) factors, and review for unreasonableness. Id. Because this inquiry would have “place[d] us in the zone of speculation and conjecture” we could not conclude that the error in Mr. Labastida-Segura’s sentence was harmless. Id. at. 1143. Accordingly, we remanded the case for resentencing. Mr. Serrano-Dominguez urges us to reach the same result. He contends that if we remand his ease, it is possible that the district court, untethered from the mandatory Guidelines, will impose a shorter sentence than the one he initially received.

He argues that the Court would have to engage in prohibitéd speculation and conjecture to conclude that he would receive the same sentence on remand. The analysis of whether Booker errors affect substantial rights—either under the rubric of harmless error or plain error—has produced much hand wringing by appellate courts. Fortunately, we do not need to read any tea leaves to determine what the district court would do on remand. With commendable prescience, the district court announced an alternative sentence, which applied the methodology suggested by Booker. Before doing so, the district court asked Mr.

Serrano-Dominguez “is it your desire to have an alternative sentence imposed here?” Through counsel, Mr. Serrano-Dominguez answered: “Sure, your honor. Yes.” The district court determined the alternative sentence by applying the § 3553(

a) factors relevant to the defendant: In considering [the § 3553(a) ] factors, I note that the defendant has a substantial criminal record. He has an apparent substance abuse problem. He has worked here in the United States but apparently has no valid Social Security number and has paid no taxes. He has apparently acquired assets, but it’s unclear how these assets came to be acquired and what the disposition of these assets is.

Under these circumstances outside the guidelines and considering the statutory factors, I would intend to impose precisely the same sentence as the guidelines require, 33 months of incarceration .... R. Vol. II at 19. The alternative sentence was exactly the same as the sentence determined using the mandatory Guidelines: 33 months. The district court’s statement eliminates any need to speculate about what it would do on remand. Cf. United States v.

Urbanek, 930 F.2d 1512, 1515-16 (10th Cir.1991) (finding that error was not harmless when the district court did not “specifically state” that a defendant’s sentence would be the same under the correct offense level). The district court applied the sentencing methodology suggested in Booker and concluded that even if the Guidelines were not mandatory Mr. Serrano-Dominguez would receive the same sentence. Consequently, the error in his sentence is harmless. A remand would needlessly burden the district court and counsel with another sentencing proceeding, which we know would produce the same result. Mr.

Serrano-Dominguez’s sentence is AFFIRMED. . 18 U.S.C. § 3553(

a) requires the sentencing court to consider factors such as the history and characteristics of the defendant, 18 U.S.C. § 3553(a)(1), the sentencing range suggested by the Guidelines, id. § 3553(a)(4), and the need for sentencing uniformity for defendants with similar criminal histories and found guilty of similar conduct, id. § 3553(a)(6). . At the beginning of the sentencing hearing, the district court asked the parties if they wished to supplement the record, and both before and after explaining the basis for the alternative sentence, the court invited the parties to make "further argument." Counsel declined both invitations.
