This is an interlocutory appeal by the government of the district court’s pretrial order excluding evidence from a mail fraud prosecution. It presents a matter of first impression in this circuit — -whether a federal honest services mail fraud prosecution under 18 U.S.C. §§ 1341 and 1346 requires proof that the conduct at issue also violated an applicable state law. Preliminarily, we must also address the government’s repeated failures to certify this appeal properly according to the jurisdictional requirements of 18 U.S.C. § 3731. We accept the government’s fourth attempt to certify, and thus have jurisdiction under § 3731. On the merits, we disagree with the district court that a state law violation is required, and thus reverse the court’s order excluding certain evidence from trial.
I. BACKGROUND
Defendant Bruce Weyhrauch, a lawyer,was a member of the Alaska House of Representatives in 2006 while Alaska’s legislature was considering legislation that would alter how the state taxed oil production. According to the criminal indictment against him, VECO Corp., an oil field services company, took an active interest in the legislature’s reconsideration of the oil tax, and two of its executives had a series of contacts with Weyhrauch regarding the pending legislation. 1 The indictment alleges that Weyhrauch solicited, by mail, telephone and personal contact, future legal work from VECO in exchange for voting on the oil tax legislation as VECO instructed and taking other actions favorable to VECO in Weyhrauch’s capacity as state legislator, such as maneuvering the legislation and reporting .information about proposed changes to the legislation to the VECO executives. The indictment does not allege that Weyhrauch received any compensation or benefits from VECO or its executives during this period, but alleges facts suggesting that Weyhrauch took the actions favorable to VECO on the understanding that VECO would hire him in the future to provide legal services to the company.
Count VII of the indictment charges Weyhrauch with devising “a scheme and artifice to defraud and deprive the State of Alaska of its intangible right to [his] honest services ... performed free from deceit, self-dealing, bias, and concealment” and attempting to execute the scheme by mailing his resume to VECO (“the honest services charge”). Before trial, the parties filed cross-motions regarding the admission or exclusion of evidence related to the honest services charge. Specifically, the government proposed to introduce: (1) legislative ethics publications containing excerpts of various Alaska state statutes addressing conflicts of interest and disclosure requirements; (2) evidence that members of the Alaska State Legislature customarily acknowledge the existence of conflicts of interests on the floor of the Legislature, and that Weyhrauch never disclosed he was negotiating for employment with VECO; (3) a description of the ethics training Weyhrauch had received; *1240 and (4) evidence that Weyhrauch served on the Legislature’s Select Committee on Ethics.
The district court found that the proffered evidence related only to duties to disclose a conflict of interest that might be imposed by
state
law, and that state law did not require Weyhrauch to disclose the conflict of interest he faced in discharging his duties while negotiating for future employment with a company affected by pending legislation.
2
The government argued that the evidence should nonetheless be admitted because proof that a legislator knowingly concealed a conflict of interest may be used to support an honest services fraud conviction even if state law does not require disclosure of the conflict of interest. Recognizing an absence of Ninth Circuit precedent and a split among the other circuits on this issue, the district court adopted the approach outlined by the Fifth Circuit in
United States v. Brumley,
II. STANDARD OF REVIEW
We review a district court’s ruling excluding evidence for abuse of discretion.
See United States v. Alvarez,
III. CERTIFICATION OF THIS APPEAL UNDER § 3731
Under 18 U.S.C. § 3731, the government may bring an interlocutory appeal “if the United States attorney certifies to the district court that the appeal is not taken for purpose of delay and that the evidence is a substantial proof of a fact material in the proceeding.”
See United States v. W.R. Grace,
Nicholas Marsh, lead trial counsel from the Department of Justice, Criminal Division, Public Integrity Section (PIS), orally advised the district court at a September 5 pre-trial conference that the government intended immediately to appeal the ruling, that the excluded evidence was substantial proof of a material fact and that the appeal was not being taken for the purpose of delay. Based on this oral certification, the district court stayed the trial pending the interlocutory appeal. However, because the purported certification to the district court was not made by the United States Attorney as required by § 3731, before oral argument we issued an order to show cause (OSC) why the appeal should not be dismissed as improperly certified.
In its response, the government argued that Marsh’s certification was sufficient under § 3731 because it was made in consultation with and at the direction of William M. Welch II, Chief of PIS, who was overseeing the prosecution, and submitted a document signed by Chief Welch, dated July 25, 2008, certifying the appeal pursu *1241 ant to § 3731. The government failed to explain how Chief Welch, who is not a United States Attorney, could properly certify an appeal under § 3731, so after oral argument we issued a second OSC to address this issue.
In response, the government submitted a formal recusal notice, dated November 7, 2005, from the Executive Office for United States Attorneys stating that the United States Attorney’s Office for the District of Alaska was recused from the investigation that led to the prosecution of Weyhrauch and that PIS had agreed to handle the matter in its entirety. The government also continued to argue that trial attorney Marsh’s September' 5, 2007 certification was sufficient, but on a new theory that he was himself authorized to certify the appeal because he had been specially appointed under 28 C.F.R. § 0.13(a) by the Deputy Assistant Attorney General and therefore was authorized to conduct “any legal proceeding, civil or criminal, including grand jury proceedings and proceedings before committing magistrates, which United States attorneys are authorized by law to conduct.” 28 C.F.R. § 0.13(a). In a published OSC, we held that the recusal notice failed to explain Chief Welch’s authority to certify the appeal and rejected the government’s argument that any attorney specially appointed under § 0.13(a) can certify an interlocutory appeal under 18 U.S.C. § 3731.
Weyhrauch,
On September 22, 2008, the government submitted two documents signed by Attorney General Michael Mukasey.
3
In the first, the Attorney General averred that the appeal was not taken for the purposes of delay and that the evidence at issue is substantial proof of facts material to the proceeding; in the second, he ratified Chief Welch’s written certification of July 25, 2008 and confirmed that Chief Welch had been delegated authority to make that certification. We accept that the Attorney General can himself certify an appeal. Plainly, Congress’ designation of the United States Attorney as the one authorized 'to make the requisite § 3731 certification was not intended to preclude certification by an equivalent or higher authority should there be no United States Attorney or acting United States Attorney overseeing a prosecution.
4
Because the ultimate authority to appoint an acting
*1242
United States Attorney rests with the Attorney General under 28 U.S.C. § 515(a),
see Weyhrauch,
Although the Attorney General’s certification is a proper substitute for that of the United States Attorney for Alaska, we must still decide whether to exercise our discretion to accept the certification at this late date.
See W.R. Grace,
Second, Weyhrauch suggests that the government’s conduct demonstrates that it did not take the § 3731 certification requirement seriously.
See W.R. Grace,
Moreover, because this case presents a factual scenario (recusal of the entire United States Attorney’s office) not addressed in any of our prior opinions (or by any other circuit) and the Attorney General has now given this issue his personal attention, we will excuse the government’s confusion and allow it to supplement the record with the Attorney General’s certification. In doing so, however, we point out that we have previously invited the government to submit documentation of prop
*1243
erly delegated authority when the certification is made by someone other than the United States Attorney,
see United States v. Wallace,
IV. HONEST SERVICES MAIL FRAUD
Accepting our jurisdiction under 18 U.S.C. § 3731, we address whether the district court properly excluded the government’s proffered evidence. Weyhrauch was indicted under 18 U.S.C. § 1341, which criminalizes the use of the postal services in carrying out a “scheme or artifice to defraud, or for obtaining money or property by means of false or fraudulent pretenses, representations, or promises.” Before 1987, we and other courts interpreted § 1341 as covering schemes to defraud another not just of money and property, but also of “intangible rights,” including the right of citizens to have public officials perform their duties honestly.
See United States v. Williams,
Rather than construe [§ 1341] in a manner that leaves its outer boundaries ambiguous and involves the Federal Government in setting standards of disclosure and good government for local and state officials, we read § 1341 as limited in scope to the protection of property rights. If Congress desires to go further it must speak more clearly than it has.
McNally v. United States,
Shortly thereafter, Congress in 1988 chose to “speak more clearly” by enacting 18 U.S.C. § 1346, specifying that for the purposes of the mail, wire and bank fraud statutes, “the term ‘scheme or artifice to defraud’ includes a scheme or artifice to deprive another of the intangible right of honest services.”
See Williams,
The district court accurately observed that we have not considered what § 1346 requires of public officials and that our sister circuits have expressed divergent views on the proper meaning of “honest services” for public officials. The Fifth Circuit has adopted the so-called “state
*1244
law limiting principle,” which requires the government to prove that a public official violated an independent state law to support an honest services mail fraud conviction.
See Brumley,
The majority of circuits, however, have held that the meaning of “honest services” is governed by a uniform federal standard inherent in § 1346, although they have not uniformly defined the contours of that standard.
See Sorich,
One concern is that a literal reading of § 1346 might give federal prosecutors
unwarranted influence
over state and local public ethics standards.
See Brumley,
The Fifth Circuit’s state law limiting principle, which the district court adopted, addresses all of these concerns. It limits *1245 how much control federal prosecutors have over state public affairs by restricting federal criminal liability to conduct prohibited by the states themselves and sets a clear outer limit to the reach of the federal statute by tying liability to violations of specific state statutes, thereby allaying concerns over fair notice. Moreover, to the extent the honest services doctrine is intended to ensure public officials act ethically, elected state officials are accountable' to their constituencies, who can punish dishonest or unethical conduct directly at the ballot box, and nonelected state officials may be subject to state ethics laws, which can be strengthened through the democratic process. Thus, because the federal criminal statutes are not the only remedy for dishonest conduct not proscribed by state law, there is some degree of logic in reserving to the states exclusive control over the ethical standards for their own public officials.
Nonetheless, we decline to adopt the state law limiting principle.
5
As an initial matter, our
pre-McNally
decisions do not support the conclusion that the federal fraud statutes derive their content solely from state law. In
United States v. Bohonus,
We also cannot find any basis in the text or legislative history of § 1346 revealing
*1246
that Congress intended to condition the meaning of “honest services” on state law. Because laws governing official conduct differ from state to state, conditioning mail fraud convictions on state law means that conduct in one state might violate the mail fraud statute, whereas identical conduct in a neighboring state would not. Congress has given no indication it intended the criminality of official conduct under federal law to depend on geography. Moreover, although the Supreme Court has warned against interpreting the mail fraud statute to allow federal prosecutors to intrude into areas traditionally governed by state law absent a clear showing that Congress intended to do so,
see Cleveland,
Finally, federal action based on a valid constitutional grant of authority is not improper simply because it intrudes on state interests.
See
U.S. Const, art. VI, cl. 2 (“[T]he Laws of the United States ... shall be the supreme Law of the land.”). Congress has a legitimate constitutional basis for preventing public officials from using the mails to perpetrate fraud,
see Badders v. United States,
*1247
Having rejected the state law limiting principle, we next consider the appropriate contours of honest services fraud. Our
pre-McNally
cases recognized two core categories of conduct by public officials that other courts have found sufficient to support an honest services conviction: (1) taking a bribe or otherwise being paid for a decision while purporting to be exercising independent discretion and (2) nondisclosure of material information.
See Bohonus,
Here, Weyhrauch allegedly voted and took other official actions on legislation at the direction of VECO while engaged in undisclosed negotiations for future legal work from VECO. These allegations describe an undisclosed conflict of interest and could also support an inference of a quid pro quo arrangement to vote for the oil tax legislation in exchange for future remuneration in the form of legal work. Because Weyhrauch’s alleged conduct falls comfortably within the two categories long recognized as the core of honest services fraud, we need not define the outer limits of public honest services fraud in this case. Accordingly, the government may proceed on its theory that Weyhrauch committed honest services fraud by failing to disclose a conflict of interest or by taking official actions with the expectation that he would receive future legal work for doing so. 8
*1248 V. CONCLUSION
We hold that 18 U.S.C. § 1346 establishes a uniform standard for “honest services” that governs every public official and that the government does not need to prove an independent violation of state law to sustain an honest services fraud conviction. Because the district court excluded the evidence based, in part, on its conclusion that the government had to prove that state law imposed an affirmative duty on Weyhrauch to disclose a conflict of interest, we reverse. The government did not appeal the district court’s ruling that the proffered evidence relates only to state law, and we express no opinion whether the proffered evidence is relevant to proving the government’s case under the standard we have announced and leave that determination to the district court’s sound judgment.
REVERSED and REMANDED.
Notes
. The government prosecuted Weyhrauch and Peter Kott, another state legislator, together. On September 5, 2007, after the government informed the parties and district court that it intended to appeal the district court’s decision excluding evidence as to Weyhrauch only, the district court granted Weyhrauch's severance motion. Kott was then tried on four of the counts in the indictment and convicted of three. Kott has appealed his conviction and sentence. See United States v. Kott, No. 07-30496. This appeal does not concern Kott’s conviction.
. The government has not appealed these aspects of the district court's ruling.
. Remarkably, the government also continued to argue that the recusal notice was sufficient to demonstrate that Chief Welch possessed authority to certify the appeal. Setting aside for the moment that the government’s filing was made in response to an order in which we squarely held that the recusal notice was insufficient, the government's continued insistence that the recusal notice is sufficient ignores the rationale for our holding: when an investigation or prosecution is being overseen by someone outside of a United States Attorney’s office, that person can certify an appeal only if properly appointed pursuant to 28 U.S.C. § 515(a) as the acting United States Attorney for the purposes of that investigation or prosecution. Although a document demonstrating that an entire United States Attorney’s office was recused from a case does suggest that someone else is running that case, it does not demonstrate that the Attorney General appropriately appointed that person as acting United States Attorney or to certify an appeal under 18 U.S.C. § 3731.
. As the government noted in its most recent filing, some investigations originate and are conducted within the Department of Justice, without any involvement of the local United States Attorney’s office. The Department would do well to adopt procedures to ensure that someone has been expressly delegated authority to certify interlocutory appeals under § 3731 in such cases.
See Weyhrauch,
. Although we reject the state law limiting principle in the context of honest services prosecutions of public officials, we express no opinion on the role of state law in honest services fraud prosecutions in the
private
context.
See Sorich,
. We recently affirmed the conviction of a private individual for honest services fraud because he breached his fiduciary duty of loyally.
See Williams,
. This prosecution illustrates how national policies are implicated by alleged fraud against the people of a state. Alaska’s oil tax legislation could influence how companies across the nation develop and exploit petroleum resources (particularly which geographic area would be a priority for investment), with consequences for the national economy and national energy policy. Under the state *1247 law limiting principle, however, the federal government would be deprived of its ability to protect these federal interests against allegedly corrupt influences simply because a state law did not expressly forbid the conduct.
. The honest services doctrine exists within the broader context of the mail and wire fraud statutes, however, so the government must still prove fraudulent intent,
