Dеfendant Hipólito Calderon-Avila appeals the district court’s 1 imposition of a sentence enhancement fоr obstruction of justice under U.S.S.G. § 3C1.1 and denial of a sentence reduction for acceptance of responsibility under U.S.S.G. § 3E1.1. We affirm.
I.
Defendant was arrested and charged with three counts of possession with intent to distribute methamphetaminе. He alleged he was a juvenile at the time of the offense and moved to dismiss the indictment. At the motion hearing, he prеsented the testimony of his sister who stated Defendant was born on November 5, 1984, making him seventeen at the time of the offense. The government presented the expert testimony of a radiologist who opined to a reasonable degree of medical certainty that Defendant’s skeletal x-rays indicated his age to be between twenty-four and twenty-sevеn. The government also relied upon stipulated evidence that Defendant had repeatedly given law enforсement officials August 19, 1975 as his birth date. The district court rejected the sister’s testimony and denied the motion. Defendant then entered a plea agreement and conditionally pled guilty to one count *507 of possession with intent to distribute 500 or morе grams of a mixture or substance containing methamphetamine.
At the sentencing hearing, the district court found that Defendаnt had suborned the perjurious testimony of his sister in support of his motion:
Well, I find that the government’s met its burden of proof on the obstruetion-of-justice issue because I find that the defendant knew his actual age and procured testimony that falsely indiсated he was under the age of 18. And to me that’s circumstantial procurement of known perjurious testimony that would fall within the guideline 3C1.1, and so I think probation properly scored obstruction of justice in this case.
Sentencing Transcript at 20. Aсcordingly, the district court enhanced Defendant’s sentence for obstruction of justice and denied a reduction fоr acceptance of responsibility. At sentencing, Defendant did not object to the fact that his presentenсe report listed his age at the time of the offense as twenty-six. Before this court he appeals only his sentence enhancement and denial of reduction for acceptance of responsibility. He does not aрpeal the denial of his motion to dismiss and no longer argues he was a juvenile at the time of the offense.
II.
We review construction of the Guidelines de novo.
United States v. Esparza,
U.S.S.G. § 3C1.1 provides that a court should increase a defendant’s offense level by two levels if “the defendant willfully obstructed or impeded, or attеmpted to obstruct or impede, the administration of justice during the ... prosecution ... of the instant offense of conviсtion.” Id. This enhancement applies to the acts of “committing, suborning, or attempting to suborn perjury.” Commentary to U.S.S.G. § 3C1.1 at Application Note 4(b). We find no clear error in the district court’s factual determination that Defendant suborned perjury.
Dеfendant argues enhancement is improper because, by alleging that he was a juvenile at the time of the offense, he merely forced the government to prove a jurisdictional prerequisite to his prosecution, namely, thаt he was over eighteen. While it is true an obstruction enhancement cannot apply to a defendant’s eleсtion to mount a defense and exercise a constitutional right, Commentary to U.S.S.G. § 3C1.1 at Application Note 2, Defendаnt does not have a constitutional right to commit or promote perjury.
United States v. Dunnigan,
*508
Defendant argues further that because he pled guilty and, after his motion to dismiss was denied, ceased obstructive conduct, it was error to deny an acceptance of responsibility reduction. We disagree. Application Note 4 to U.S.S.G. § 3E1.1 states that conduct which supports an obstruction of justice enhancement “ordinarily indicates that the defendant has not accepted responsibility” as required for a two level reduction under § 3E1.1 but that “[t]here may be ... extraordinary cases in which adjustments under both §§ 3C1.1 and 3E1.1 may apply.” In
United States v. Honken,
we held “the mere fact of the guilty plea to the underlying offense, followed by an absence of post-plea obstructive conduct is not by itself sufficient to establish an extraordinary case as a matter of law... ”.
The district court’s application of an obstruction of justice enhancement and refusal to apply an acceptance of responsibility reduction are affirmed.
