Defendant-Appellant Christopher Noah Mollner pleaded guilty to armed bank robbery, in violation of 18 U.S.C. § 2113. Pri- or to sentencing, the district court granted the government’s motion to compel Mr. Mollner to testify at the trial of his co-defendant, Ira Burdell Wakefield, and to grant Mr. Mollner immunity for his testimony. However, Mr. Mollner refused to testify. At Mr. Mollner’s sentencing hearing, the district court adjusted his offense level upward by two levels for obstruction of justice under U.S. Sentencing Guidelines Manual (“U.S.S.G.”) § 3C1.1 based upon Mr. Mollner’s refusal to testify, and sentenced Mr. Mollner to 100 months’ imprisonment. 1
On appeal, Mr. Mollner challenges the district court’s application of the obstruction-of-justice enhancement. Exercising jurisdiction under 28 U.S.C. § 1291, we conclude that the district court did not err by increasing Mr. Mollner’s offense level for obstruction of justice. Accordingly, we AFFIRM his sentence.
DISCUSSION
“[W]e review sentences for reasonableness under a deferential abuse-of-discretion standard.”
United States v. Alapizco-Valenzuela,
The district court concluded that Mr. Mollner’s “refusal to testify at his co-defendant’s trial after the immunity order was issued constituted a willful obstruc *715 tion of justice under Section 3C1.1,” and applied the two-level enhancement. R., Supp. Vol. 2, at 16 (Sentencing Hr’g Tr., dated July 8, 2009). On appeal, Mr. Mollner argues that because his “refusal to testify at his co-defendant’s trial did not obstruct the investigation, prosecution, or sentencing of Ms own offense, the adjustment was clearly inapplicable.” Aplt. Opening Br. at 13 (emphasis added).
1. Bernaugh and Amendment 581 to U.S.S.G. § 3C1.1
Prior to November 1, 1998, it was clear in this circuit that U.S.S.G. § 3C1.1 applied to a defendant who obstructed justice in a case closely related to his own. During that period, U.S.S.G. § 3G1.1 provided that “[i]f the defendant willfully obstructed or impeded, or attempted to obstruct or impede, the administration of justice during the investigation, prosecution, or sentencing of the instant offense, increase the offense level by 2 levels.” U.S.S.G. § 3C1.1 (1990). We interpreted this version of U.S.S.G. § 3C1.1 in
United States v. Bernaugh,
and held that “the section 3C1.1 enhancement applies where a defendant attempts to obstruct justice in a case closely related to his own, such as that of a codefendant.”
However, in 1998, subsequent to our decision in Bernaugh, the Sentencing Commission amended U.S.S.G. § 3C1.1. In Amendment 581, the Commission set forth the substance of the amendment and explained the reasons for it. See U.S.S.G. app. C, amend. 581 (2001). As a result of this amendment, effective November 1, 1998, the text of U.S.S.G. § 3C1.1 read:
If (A) the defendant willfully obstructed or impeded, or attempted to obstruct or impede, the administration of justice during the course of the investigation, prosecution, or sentencing of the instant offense of conviction, and (B) the obstructive conduct related to (i) the defendant’s offense of conviction and any relevant conduct; or (ii) a closely related offense, increase the offense level by 2 levels.
U.S.S.G. § 3C1.1 (1998). 2
Amendment 581 also added a new application note 1 to the commentary of U.S.S.G. § 3C1.1:
This adjustment applies if the defendant’s obstructive conduct (A) occurred during the course of the investigation, prosecution, or sentencing of the defendant’s instant offense of conviction, and (B) related to (i) the defendant’s offense of conviction and any relevant conduct; or (ii) an otherwise closely related case, such as that of a co-defendant.
U.S.S.G. § 3C1.1 cmt. n. 1 (1998). 3
Mr. Mollner contends that, in light of Amendment 581’s changes to U.S.S.G. § 3C1.1 and its application notes, Bernaugh is no longer controlling precedent. See Aplt. Opening Br. at 9. Mr. Mollner reasons that:
While the literal language of the guideline in § 3C1.1 seems to apply broadly to the “instant offense of conviction,” the application notes restrict the scope of this adjustment. Indeed, while the pertinent application note closely tracks the language of the guideline, there is one critical distinction, namely that the application note requires that the obstruc *716 tive conduct occur with respect to “the defendant’s instant offense of conviction.” While this deviation is slight, it nonetheless clearly indicates the Commission’s intent to restrict application of the adjustment to obstructive conduct relating solely to the defendant’s instant offense of conviction.
Id. at 10-11 (citation omitted).
Accordingly, Mr. Mollner asserts that because his “refusal to testify at his co-defendant’s trial did not obstruct the investigation, prosecution, or sentencing of his own offense, the adjustment [for obstruction of justice] was clearly inapplicable.” Id. at 13 (emphasis added).
We have not yet determined whether Bemaugh’s holding survived Amendment 581 such that U.S.S.G. § 3Cl.l’s enhancement continues to apply to a defendant’s obstruction of justice in a closely related case, such as that of a co-defendant.
II. U.S.S.G. § 3C1.1, as Amended by Amendment 581
The Sentencing Commission and some of our sister circuits have explained that the amended version of U.S.S.G. § 3C1.1 applies not only to the defendant’s obstructive conduct involving his offense of conviction, but also to any of his obstructive conduct involving cases that are closely related to the defendant’s case. We agree.
The Sentencing Commission explained that its purpose in issuing Amendment 581 was
to clarify what the term “instant offense” means in the obstruction of justice guideline, § 3C1.1. This amendment resolves a circuit conflict on the issue of whether the adjustment applies to obstructions that occur in cases closely related to the defendant’s case or only those specifically related to the offense of which the defendant [was] convicted. The amendment, which adopts the majority view, instructs that the obstruction must relate either to the defendant’s offense of conviction (including any relevant conduct) or to a closely related case.
U.S.S.G. app. C, amend. 581 (emphasis added) (citations omitted).
In noting that it was coming down on the side of the majority view, the Commission expressly acknowledged our decision in Bemaugh as reflecting that view. See id. In other words, the Commission indicated that the effect of the amendment was to embrace the holding of Bemaugh, not to reject it.
Several of our sister circuits have interpreted U.S.S.G. § 3C1.1, as revised by Amendment 581, in conformity with the Commission’s explanation. Specifically, they have held that a defendant’s perjurious testimony in a co-defendant’s proceeding supports the application of the obstruction-of-justice enhancement.
4
In
United States v. Savoca,
the defendant claimed that his perjurious testimony at his co-defendant’s trial “did not constitute the prosecution of his own ‘instant offense of conviction,’ and thus, cannot qualify for an obstruction of justice enhancement.”
Similarly, in
United States v. Killingsworth,
defendant Williams argued that his perjurious testimony at co-defendant Killingsworth’s pre-sentencing evidentiary hearing could not “give rise to an obstruction-of-justice adjustment since the perjury occurred in a proceeding that involved another defendant.”
In
United States v. Messino,
the defendant argued that “his offending statements were immaterial to
his own
sentence and conviction because they were made during his testimony at the trial of [his] co-defendants.”
The Fourth and Ninth Circuits have also rejected the argument that Amendment 581 narrowed the scope of § 3C1.1 to exclude obstructive conduct that does not have a direct nexus to the defendant’s offense of conviction.
See United States v. Jones,
The Third and Sixth Circuits have indicated that they likely would rule similarly.
See United States v. Burke,
Mr. Mollner’s contrary analysis — which attributes great significance to the placement of the word “defendant’s” before the language “instant offense of conviction” in application note 1 of § 3Cl.l’s commentary — is unavailing. Mr. Mollner cites to no authority that even suggests that the Sentencing Commission intended the lone word “defendant’s” to engage in such herculean work — viz., to dramatically restrict the scope of the language of § 3Cl.l’s text, which Mr. Mollner acknowledges “applies] broadly to the ‘instant offense of conviction,’ ” Aplt. Opening Br. at 10, such that *718 the obstruetion-of-justice enhancement only applies to a defendant’s obstructive conduct committed with respect to his offense of conviction. Nor are we aware of any such authority.
Given the controlling effect ordinarily accorded to Guidelines commentary,
see Stinson v. United States,
In this regard, in discerning the effect of Amendment 581, instead of trying to engage in an act of linguistic alchemy with respect to the lone term “defendant’s” in application note 1, we consider it much more useful to focus on what the Sentencing Commission, in pellucid language, said that it was doing: “The amendment ... instructs that the obstruction must relate either to the defendant’s offense of conviction (including any relevant conduct)
or
to a closely related case.” U.S.S.G. app. C, amend. 581 (emphasis added). Our sister circuits also have looked to the Sentencing Commission’s explanation for Amendment 581 in assessing its import.
See Killingsworth,
To bolster his argument, Mr. Mollner relies on the Supreme Court’s decision in
Stinson.
There, the Court remarked: “[W]e can presume that the interpretations of the guidelines contained in the commentary represent the most accurate indications of how the Commission deems that the guidelines should be applied to be consistent with the Guidelines Manual as a whole as well as the authorizing statute.”
Stinson,
In sum, in light of the Sentencing Commission’s clear explanation that Amendment 581 was adopted to clarify that the term “instant offense” includes obstructions of justice in cases closely related to the defendant’s case — a position that the Commission explicitly noted was endorsed by Bemaugh — and also given the decisions of our sister circuits interpreting the amended version of U.S.S.G. § 3C1.1 in a *719 manner consonant with the Commission’s explanation, we conclude that our holding in Bemaugh is still good law. That is, the obstruction-of-justice enhancement applies where a defendant attempts to obstruct justice in a case closely related to his own, such as that of a co-defendant, even after the Commission’s adoption of Amendment 581. Accordingly, we hold that the district court appropriately applied this enhancement to Mr. Mollner, who refused to testify in his co-defendant’s case after being ordered to testify and being granted immunity for his testimony.
CONCLUSION
For the reasons set forth above, we AFFIRM Mr. Mollner’s sentence.
