The District Court accepted the Government's position that Imenec's failure to appear at his preliminary hearing in Pennsylvania state court in 1991 was a willful failure to appear at a judicial proceeding, justifying the upward departure pursuant to Application Note Three of § 3C1.1. Imenec concedes that he failed to appear at a state judicial proceeding, but he argues that, because it was a state, rather than a federal, court, his failure to appear was outside the ambit of § 3C1.1. The only "effect" his action had upon federal proceedings, he argues, was to avoid or delay his arrest, an action that Application Note Four of § 3C1.1 clearly excludes. The District Court was unpersuaded by Imenec's proposed construction of § 3C1.1. We exercise plenary review over the District Court's interpretation of the Sentencing Guidelines. See United States v. Powell, 113 F.3d 464, 467 (3d Cir. 1997).

The answer to whether a § 3C1.1 obstruction of Justice enhancement is appropriate in this case depends on whether "instant offense" is understood to refer to the criminal conduct underlying the specific offense of conviction, as the government contends, or is read to be limited to the specific offense of conviction itself, as Imenec insists. Based on the text and purpose of § 3C1.1, we conclude that the Sentencing Commission's intent was to impose an enhancement for any conduct that obstructs an investigation, prosecution or sentencing proceeding that is based on the criminal conduct underlying the specific statutory offense for which the defendant is being sentenced.

Section 3C1.1 imposes a sanction for conduct that obstructs an official criminal investigation, even though the investigation has not yet matured into a prosecution and, indeed, even though no thought has yet been given to what the appropriate criminal charge might be. As a result, we believe it unlikely that the Sentencing Commission intended to require a nexus between the specific statutory offense and the obstructed investigation beyond a showing that the conduct being investigated gave rise to the criminal charge ultimately decided upon.

Moreover, we believe the intent reflected in the text of § 3C1.1 is the one most consistent with its purpose. As the Court of Appeals put it in United States v. Emery, 991 F.2d 907 (1st Cir. 1993):

[T]he obstruction-of-Justice enhancement rests on the rationale that "a defendant who commits a crime and then... [makes] an unlawful attempt to avoid responsibility is more threatening to society and less deserving of leniency than a defendant who does not so defy" the criminal Justice process.

Id. at 912 (quoting United States v. Dunnigan, 507 U.S. 87, 97 (1993)). As the Emery court went on to point out, the threat that the defendant poses and his or her culpability with respect to the offense of conviction are not lessened by the happenstance that the obstructive conduct occurred at a time when state, rather than federal, authorities were conducting the investigation of the conduct underlying the offense of conviction.

Because we interpret "the instant offense" in the manner suggested by the government, we conclude that a§ 3C1.1 enhancement is appropriate where the defendant has obstructed an investigation of the criminal conduct underlying the offense of conviction, even where the investigation was being conducted by state authorities at the time. Given that interpretation, we further conclude and hold that a § 3C1.1 enhancement is appropriate where the defendant has obstructed a prosecution based on the same criminal conduct underlying the offense of conviction even though that prosecution is going forward in a state court.

Our holding is consistent with and supported by our existing circuit jurisprudence. In United States v. Powell, 113 F.3d 464 (3d Cir. 1997), we construed § 3C1.1 as applying, not only to conduct obstructing the proceedings against the defendant himself, but also to conduct obstructing a separate trial of a co-defendant on a charge based on the same criminal conduct underlying the defendant's offense of conviction. In Powell, the defendant had been convicted of conspiracy to distribute cocaine with his brother. The defendant pled guilty to the conspiracy, but then, in an effort to impede his brother's prosecution, he testified falsely at his brother's trial. The District Court applied § 3C1.1 and imposed a two level enhancement on Powell. On appeal, Powell argued that § 3C1.1 was inapposite, because his conduct did not obstruct the "instant offense." We rejected that argument and held that § 3C1.1 "applies where a defendant attempts to obstruct Justice in a case closely related to his own...." Id.

While Powell involved two federal prosecutions, its holding is inconsistent with an understanding that "prosecution" in § 3C1.1 is limited to the prosecution that produced the conviction for which the defendant is being sentenced. It is consistent with the notion that § 3C1.1 applies to conduct obstructing any investigation, prosecution or sentencing proceeding based on the same criminal conduct that underlies the offense for which the defendant is being sentenced. Indeed, it seems to us that this case follows a fortiori from Powell, since Imenec, in obstructing the state prosecution, was attempting, unlike Powell, to avoid accountability for his own criminal conduct.

Cases from other Courts of Appeals also provide support for our holding. See United States v. Smart, 41 F.3d 263, 265-66 (6th Cir. 1994) (per curiam) (argument that failure to appear at state court proceeding was unrelated to the "instant" case "is simply not tenable"); United States v. Adediran, 26 F.3d 61, 65 (8th Cir. 1994) ("this circuit does not prohibit obstruction enhancement in federal prosecutions merely because state entities were involved"). In addition, other Circuit Courts of Appeals have expansively interpreted § 3C1.1 to require enhancement for conduct obstructing state investigations, even when the obstructive conduct occurred before federal charges were filed or a federal investigation was even initiated. See United States v. Self, 132 F.3d 1039, 1042 (4th Cir. 1997) ("[s]section 3C1.1 draws no distinction between a federal investigation and a state investigation"); United States v. Emery, 991 F.2d 907, 911-12 (1st Cir. 1993) ("so long as some official investigation is underway at the time of the obstructive conduct, the absence of a federal investigation is not an absolute bar to the imposition of a section 3C1.1 enhancement"); United States v. Lato, 934 F.2d 1080, 1083 (9th Cir. 1991) (obstruction of a state investigation properly considered for purposes of a 3C1.1 enhancement).

In Conclusion, we hold that § 3C1.1 requires a two level enhancement when a defendant fails to appear at a judicial proceeding, state or federal, relating to the conduct underlying the federal criminal charge. Accordingly, the judgment of the District Court will be affirmed.
