An indictment charges Lawrence Bloom— between 1979 and 1995 the Alderman for Chicago’s Fifth Ward — with corruption in office. The question presented by the prosecutor’s interlocutory appeal under 18 U.S.C. § 3731 is whether a portion of Count I, which accuses Bloom of mail fraud, charges a pub-lie-capacity or only a private-capacity offense. The district court dismissed Count I to the extent it alleges that Bloom schemed to deprive Chicago of the intangible right to his honest services, holding that the charge properly claims only that Bloom schemed to deprive the City of tax revenues.
Aldermanic positions in Chicago are part-time jobs. In his private life, Bloom is a lawyer. Count I charges that Bloom counseled one of his clients to use a proxy bidder at a tax scavenger sale. (We recount the allegations, whose truth remains to be determined.) Komed Health Center, the client, *651owned real property on which it owed more than $283,000 in real estate taxes. Property taxes, although levied by Cook County, flow through to the City’s coffers. Counties in Illinois sell properties with tax delinquencies at auction; the high bidder receives a certificate, which becomes a tax deed if the owner does not redeem the property by paying all back taxes plus interest. 35 ILCS 200/21-260. Another section of the statute requires each bidder to certify that “the person has not bid upon or applied to purchase any property at the sale for a person who is the party or agent of the party who owns the property or is responsible for the payment of the delinquent taxes”. 35 ILCS 200/21-265(a)(1). Illinois permits the winning bidder at a tax scavenger sale to sell his rights to the original owner, even though that-wipes out the owner’s incentive to redeem by paying delinquent taxes to the county. The state apparently believes, however, that these transactions would occur too frequently if bidders were agents-or nominees of the owners. Bloom advised Komed that it could avoid paying taxes, yet retain control of the property, by sending to the auction a person who had agreed to sell the certificate or tax deed to Komed. Bloom told Komed that thé maneuver was illegal but added that people did it all the time. Komed’s agent later made the winning bid and, after the redemption period expired, conveyed the property back to Komed, which thus avoided most of its taxes. (The County recovered only the amount bid at the auction; Komed paid this, plus a premium to its agent, and saved the balance of the tax bill.) •
The prosecutor has identified two theories under which the scheme was mail fraud (use of the mails being integral to tax scavenger sales) in violation of 18 U.S.C. § 1341: first, the arrangement finagled the City and County out of revenues they might have received had they known the truth about the proxy’s allegiance and disqualified him from participating in the auction; second, the arrangement deprived the City of Bloom’s honest services. According to the prosecutor, Bloom was a fiduciary who owed the City a duty of loyalty and therefore was required, when practicing law, to refrain from participating in or giving advice.about any transaction that could reduce the City’s revenues. In re Vrdolyak, 137 Ill.2d 407, 148 Ill.Dec. 243, 560 N.E.2d 840 (1990), holds that another lawyer-alderman violated his ethical duties when he represented persons who had legal claims against the City, because any increase in his clients’ recoveries necessarily would reduce the City’s assets. Although vigorous representation of the same clients by a lawyer without ties to the City could have produced the same or greater outlays, the Supreme Court of Illinois thought that it conveys the .wrong appearance for a fiduciary of the City to be the advocate of the City’s adversary, especially in light of the, possibility that the lawyer representing the City will find it prudent to accommodate an alderman who sits on the opposite side of the table. Similar reasoning, according to the prosecutor, shows that lawyer-alderman Bloom violated his duty to give Chicago his undivided loyalty. Of course Vrdolyak was about ethics rather than fraud, and few violations of ethical duties are .federal crimes. What the prosecutor needs is a way to equate unethical conduct with a “scheme or artifice to defraud”, the key language of § 1341. Although McNally v. United States, 483 U.S. 350, 107 S.Ct. 2875, 97 L.Ed.2d 292 (1987), scotched the “intangible rights” doctrine that treats some violations of fiduciary duty as fraud, Congress enacted in 1988 a statute providing: “For the purposes of this chapter, the term ‘scheme or artifice to defraud’ includes a scheme or artifice to deprive another of the intangible right of honest services.” 18 U.S.C. § 1346. The Komed scavenger sale occurred in 1991, so Bloom’s acts are covered by § 1346. But the district judge dismissed Count I, to the extent it rests on the intangible rights doctrine; because he thought that the Vrdolyak ruling deemed unethical only participation in litigation against the City and did not condemn all activities (such as tax-planning advice) that might indirectly affect the City’s revenues.
I
Our first question is whether the prosecutor is entitled to interlocutory review of this order. Section 3731, the Criminal Appeals Act, authorizes appeal from an order *652“dismissing an indictment or information ... as to any one or more counts, except that no appeal shall lie where the double jeopardy clause of the United States Constitution prohibits further prosecution.” The district court did not dismiss Count I; it just excised the intangible rights theory. Relying on the text of § 3731, Bloom argues that we lack jurisdiction. If the text of the statute were the last word, we would be inclined to agree. See United States v. Spilotro, 884 F.2d 1003, 1005 (7th Cir.1989); United States v. Horak, 833 F.2d 1235 (7th Cir.1987). But it is not. In United States v. Wilson, 420 U.S. 332, 337, 95 S.Ct. 1013, 43 L.Ed.2d 232 (1975), and United States v. Martin Linen Supply Co., 430 U.S. 564, 568, 97 S.Ct. 1349, 51 L.Ed.2d 642 (1977), the Court wrote that § 3731 is “intended to remove all statutory barriers” to appeals from orders terminating prosecutions. Neither of these cases involved an appeal from an order paring down a single count, but Sanabria v. United States, 437 U.S. 54, 98 S.Ct. 2170, 57 L.Ed.2d 43 (1978), did, and stated:
We agree with the Court of Appeals ... that there is no statutory barrier tq an appeal from an order dismissing only a portion of a count. One express purpose of 18 U.S.C. § 3731 (1976 ed.) is to permit appeals from orders dismissing indictments “as to any one or more counts.” A “count” is the usual organizational subunit of an indictment,, and it would therefore appear that Congress intended to authorize appeals from any order dismissing an indictment in whole or in part. Congress could hardly have meant appealability to depend on the initial decision of a prosecutor to charge in one count what could also have been charged in two, a decision frequently fortuitous for purposes of the interests served by § 3731. To so rule would import an empty formalism into a statute expressly designed to eliminate “[technical] distinctions in pleadings as limitations on appeals by the United States.” H.R. Conf. Rep. No. 91-1768, p. 21 (1970); accord, S.Rep. No. 91-1296, p. 5 (1970). We note that the only Court of Appéals other than the court below that has considered this question reached a similar result. United States v. Alberti, 568 F.2d 617 (C.A.2 1977).
437 U.S. at 69 n. 23, 98 S.Ct. 2170. Bloom asks us to dismiss this passage as dictum and to hold that only an order dismissing an entire count may be appealed. United States v. Louisiana Pacific Corp., 106 F.3d 345 (10th Cir.1997), supports Bloom’s position, but we are unpersuaded. Other courts of appeals likewise believe that the footnote in Sanabria is authoritative. United States v. Levasseur, 846 F.2d 786, 790 (1st Cir.1988); United States v. Tom, 787 F.2d 65, 70, 71 (2d Cir.1986); United States v. Hill, 55 F.3d 1197, 1199 (6th Cir.1995); United States v. Martin, 733 F.2d 1309 (8th Cir.1984); United States v. Marubeni America Corp., 611 F.2d 763, 764-65 (9th Cir.1980); United States v. Oakar, 111 F.3d 146, 149-50 (D.C.Cir.1997).
Louisiana Pacific starts from the premise that “there is a presumption against the availability to the government of an interlocutory appeal in a criminal case.” 106 F.3d at 348. That was so before the Criminal Appeals Act was amended in 1970, but not since.. Paragraph 5 of § 3731 tells courts to construe the rest of § 3731 liberally. Wilson and Martin Linen say that ¶ 5 reverses the old presumption and that today the prosecutor may appeal from terminating orders (and some other orders that jeopardize prosecutions, such as orders suppressing evidence) whenever the double jeopardy clause permits. Limitations now depend on § 3731, not on an outdated judicial hostility to prose-cutorial appeals.
Is a theory of criminal liability a “count” for purposes of § 3731? Sanabria answers “yes”. Justice Stevens filed separate opinions in Martin Linen and Sanabria, contending that § 3731 should be read with an eye to curtailing interlocutory appeals, which meant to him that “count” should be understood to mean “all of a count” rather than “a theory of criminal liability in a count.” In Louisiana Pacific the tenth circuit wrote that “Justice Stevens points out the flaw in the Court’s dicta regarding” appeals under § 3731. 106 F.3d at 349. But no matter what we may think about the strength of the competing arguments, in both Martin Linen and Sanabria Justice Stevens was a minority *653of one. An inferior court is not entitled to say that because the one is more persuasive than the eight, it will follow the one. Even if the passage could be called dictum, it is a not an aside unrelated to the subject of the case. The question had been briefed by the parties, so the statement was informed rather than casual; it is a considered expression by the Court supported by earlier cases (such as Wilson) that supply more extensive analysis and is not incompatible with any decision before or since. Contrast Zenith Radio Corp. v. United States, 437 U.S. 443, 460-62, 98 S.Ct. 2441, 67 L.Ed.2d 337 (1978). It would ill serve the interests of litigants and the judicial system as a whole to row against the tide of such statements. See Reich v. Continental Casualty Co., 33 F.3d 754, 757 (7th Cir.1994); United States v. Underwood, 717 F.2d 482, 484-86 (9th Cir.1983) (en banc). The Supreme Court often articulates positions through language that an unsympathetic audience might dismiss as dictum— consider the catalog of rules in Miranda v. Arizona, 384 U.S. 436, 86 S.Ct. 1602, 16 L.Ed.2d 694 (1966) — and it expects these formulations to be followed. See Baxter v. Palmigiano, 425 U.S. 308, 96 S.Ct. 1551, 47 L.Ed.2d 810 (1976) (disapproving, with some asperity, a court’s decision to alter one of the guidelines announced, arguably in dictum, in Wolff v. McDonnell, 418 U.S. 539, 94 S.Ct. 2963, 41 L.Ed.2d 935 (1974)). The Court can hear only a small portion of all litigated disputes; it uses considered dicta to influence others for which there is no room on the docket. Appellate courts that dismiss these expressions and strike off on their own increase the disparity among tribunals (for other judges are likely to follow the Supreme Court’s marching orders) and frustrate the evenhanded administration of justice by giving the litigants an outcome other than the one the Supreme Court would be likely to reach were the case heard there.
As it happens, however, Sanabria’s treatment of § 3731 was not dictum. It was no stray remark or aside. It explains the Court’s rationale and thus is part of the holding. See United States v. Crawley, 837 F.2d 291 (7th Cir.1988). The district court dismissed one theory of liability in an indictment; the prosecutor appealed; both the court of appeals and the Supreme Court concluded that § 3731 authorizes such an appeal if further prosecution would not be barred by the double jeopardy clause. Disagreeing with the court of appeals, the Supreme Court held that the double jeopardy clause did bar retrial. It was this additional conclusion that led the tenth circuit to call its treatment of § 3731 dictum. But the Court reached the double jeopardy question only because its reading of § 3731 made it disposi-tive. Had the majority agreed with Justice Stevens about the meaning of § 3731, it would have done as he urged: it would have ordered the appeal dismissed without turning to the Constitution. Longstanding practice calls for federal judges to explore all non-constitutional grounds of decision before addressing constitutional ones — and especially to decide first whether any statute confers jurisdiction. See Wilson, 420 U.S. at 336, 95 S.Ct. 1013. See also Steel Co. v. Citizens for a Better Environment, — U.S. -, -- -, 118 S.Ct. 1003, 1012-16, 140 L.Ed.2d 210 (1998). That is what the Court did in Sanabria. It would make little sense to treat this wise effort to avoid constitutional issues as an affront to. Article III of the Constitution — that is, as producing only advisory opinions on the statutory issues — the way the tenth circuit did in Louisiana Pacific.
Bloom has a fallback argument on jurisdiction. Several appellate decisions that entertained appeals from orders dismissing parts of counts did so only after concluding that the dismissed portion “provides a discrete basis for the imposition of criminal liability.” Oakar, 111 F.3d at 149-50 (citing other cases). Although the Sanabria footnote concludes that “Congress intended to authorize appeals from any order dismissing an indictment in whole or in part.” 437 U.S. at 69 n. 23, 98 S.Ct. 2170 (emphasis added), these courts believe that the “discrete basis” approach is a useful way to limit attention to important disputes.' We need not decide whether to embrace the “discrete basis” approach because it is satisfied when (as in Sanabria itself) the judge removes a theory of liability — as opposed to, say, a single overt *654act from a conspiracy charge, or a particular predicate act in a RICO ease.
Unless the district judge perceived that the portion of Count I he dismissed “provides a discrete basis for the imposition of criminal liability”, he either would have dismissed the entire count or would not have dismissed any of it. It is only because the language to which Bloom objects “provides a discrete basis for the imposition of criminal liability” that it made sense to dismiss part of Count I. It would be unwise to allow Bloom — who persuaded the district judge that one part of the charge is legally distinct enough from another — to argue now that the part dismissed and the part retained are so similar that the appeal should be dismissed. That would make a virtue of inconsistency. To the extent United States v. Margiotta, 662 F.2d 131, 139-41 (2d Cir.1981), let a defendant succeed with such a Janus-faced argument, we do not follow it..
II
The district judge concluded that Vrdolyak does not deem unethical every instance in which a lawyer-alderman gives a client advice that could harm the City’s financial interests. Reading Vrdolyak the way the prosecutor does would foreclose even legitimate legal advice, the judge thought, such as informing a client that it is possible to protest through administrative channels the County’s increase in assessed property-tax valuation. All Vrdolyak requires, the court concluded, is that the lawyer-alderman avoid representing a client in litigation against the City. The United States seeks to persuade us that Vrdolyak establishes the much broader rule that aldermen and other public employees may not do anything in their private lives that acts against the City’s interests — but if its rule were that broad, then every city employee would be required to shop exclusively in Chicago in order to maximize its receipts from sales taxes, and would be guilty of a federal felony if he bought a pair of boots through the mail from L.L. Bean. Even if the employee paid the countervailing use tax that applies when a local sales tax has not been collected (compare 35 ILCS 105/4 with 35 ILCS 105/3-55(d)), the crime would have been committed, for Illinois collects only its own tax, not the supplemental sales tax that the City imposes on local purchases. Doubtless there is a limiting principle and some conflicts of interest are tolerable; a member of General Motors’ board of directors is (legally) entitled to drive a Ford; but it is frightening to contemplate the prospect that the federal mail fraud statute makes it a crime punishable by five years’ imprisonment to misunderstand how a state court in future years will delineate the extent of impermissible conflicts. Then we would have a federal common-law crime, a beastie that many decisions say cannot exist. E.g., United States v. Bass, 404 U.S. 336, 348, 92 S.Ct. 515, 30 L.Ed.2d 488 (1971); United States v. Hudson, 11 U.S. (7 Cranch) 32, 3 L.Ed. 259 (1812); United States v. Reynolds, 919 F.2d 435, 438 (7th Cir.1990). See also McNally, 483 U.S. at 360, 107 S.Ct. 2875. Courts have applied this no-common-law-crimes principle to mail fraud prosecutions by holding that violations of state-law fiduciary duties do not turn into mail fraud just because the mails are used in the process. “Not every breach of every fiduciary duty works a criminal fraud.” United States v. George, 477 F.2d 508, 512 (7th Cir.1973). See also United States v. Walters, 997 F.2d 1219 (7th Cir.1993), which rejects the idea that all deceits are criminal fraud. But if “not every breach” is criminal fraud, where is the line drawn? Its location cannot be found by parsing § 1341 or § 1346, a profound difficulty in a criminal prosecution.
One way to cope with this problem would be to limit prosecutions to cases in which a defendant’s acts not only violated a fiduciary duty but also transgressed some other rule of law. Over and over the prosecutor’s brief emphasizes that Bloom advised Komed to violate 35 ILCS 200/21 — 265(a)(1). As a limiting principle, this has two shortcomings. First, Bloom did not violate 35 ILCS 200/21-265(a)(1); only Komed and the straw purchaser did so. Second, and more important, this line of argument has nothing to do with Bloom’s status as an alderman. If advising a client to violate a state law in order to avoid paying taxes is a scheme to defraud the governmental body that should have received those taxes (and we express no opinion on *655the subject), then every member of the bar would be as culpable as Bloom. What the intangible rights theory adds is the possibility that a public employee commits a crime even when state law allows the client to do what the lawyer recommends. Then the fiduciary status makes a difference, for in an intangible rights case what the employer loses is the employee’s loyalty, not (necessarily) money or other property. Again consider Vrdolyak. No one thought that Alderman Vrdolyak had violated (or counseled the violation of) any state law by representing persons who had filed workers’ compensation claims against the City. It was the conflict of interest, and not any other impropriety, that the Supreme Court of Illinois thought objectionable. On the prosecution’s approach, any lawyer-alderman who pursues a workers’ compensation ease against the City tomorrow commits a felony, even if the City wins and never pays a penny in compensation (or pays no more than what it would have paid had some other lawyer represented the claimant).
An intangible rights indictment based as this one is on Vrdolyak necessarily asserts that every conflict of interest is a federal crime. Suppose, for example, that Bloom had described the tax scavenger sale system to Komed, told it not to send a straw bidder, and added that after the auction Komed lawfully could approach the winning buyer with a proposal to repurchase the property. Or suppose Bloom had told Komed that taxes are lower in the suburbs and advised it to relocate. Under the prosecutor’s theory, this advice is a federal felony — for, if acted on, the advice could reduce the City’s tax income, and by giving the advice the lawyer-alderman therefore deprived the City of its right to his complete loyalty, a deprivation that occurs even if the advice is not taken. Approving that position would extend the intangible rights definition of “fraud” beyond sensible bounds, creating a common-law crime in the process.
In McNally the Supreme Court described the intangible rights theory this way: “a public official owes a fiduciary duty to the public, and misuse of his office for private gain is a fraud.” 483 U.S. at 355, 107 S.Ct. 2875. This is the theory that McNally disapproved as unsupported by § 1341, and that by enacting § 1346 Congress reinstated. We do not think that § 1346, with its unelaborat-ed reference to “a scheme or artifice to deprive another of the intangible right of honest services”, creates criminal liability for events that would not have been crimes before McNally. But if McNally’s description of the intangible rights doctrine is accurate, then it is clear that Count I does not charge Bloom with an intangible rights fraud. For it does not charge that he misused his office for private gain. It does not charge that he used his office in any way, let alone that he misused it.
Misuse of office (more broadly, misuse of position) for private gain is the line that separates run of the mill violations of state-law fiduciary duty — such as Alderman Vrdol-yak’s representation of a client against the City — from federal crime. It is how we can give substance to the statement in George that “[n]ot every breach of every fiduciary duty works a criminal fraud.” In almost all of the intangible rights cases this circuit has decided (before McNally or since § 1346), the defendant used his office for private gain, as by accepting a bribe in exchange for official action. E.g., United States v. Holzer, 816 F.2d 304 (7th Cir.), vacated in fight of McNally, 484 U.S. 807, 108 S.Ct. 53, 98 L.Ed.2d 18 (1987); United States v. Isaacs, 493 F.2d 1124, 1149-51 (7th Cir.1974). The prosecutor relies principally on United States v. Keane, 522 F.2d 534 (7th Cir.1975), which sustained the conviction of an alderman who plotted to divert to favored buyers property offered at tax scavenger sales, and United States v. Bush, 522 F.2d 641 (7th Cir.1975), which affirmed the conviction of a public employee (the Mayor’s press secretary) who was a silent partner in a firm that obtained a public contract. In neither of these cases, the prosecutor asserts, did the defendant take any action in his public capacity. But the indictments in both Bush and Keane alleged that the defendants converted to private use information that they possessed by virtue of their public positions.
Secret conversion of information received in a fiduciary capacity is a form of fraud against the owner of that information. *656See United States v. O’Hagan, — U.S. -, 117 S.Ct. 2199, 138 L.Ed.2d 724 (1997). The Court held in O’Hagan that a lawyer who by virtue of his position in the law firm knew about a client’s impending tender offer defrauded the client by using the confidential information to buy stock for his own account. Bush and Keane were doing much the same thing with confidential information they obtained in their public positions, though they used it in tax sales rather than stock transactions. The Court did not say or imply in O’Hagan that it would have been a criminal fraud had the lawyer given a second client legal advice that might have undermined the first client’s business interests. Giving such advice might violate principles of legal ethics, but it would not defraud anyone. Yet this hypothetical is pretty much what the indictment charges Bloom with doing. Nothing in Count I of the indictment alleges that Bloom held any confidential information in his capacity as the City’s fiduciary, or that he used to Komed’s benefit any information that he received because he was an alderman. It does not allege that Bloom learned about the possibility of straw bidders because of his status as an alderman or that his public position facilitated his advice to Komed in any way. Only by abandoning the principle of George that there is a difference between fraud and a simple breach of fiduciary duties could we conclude that Count I states an intangible rights fraud.
No case we can find in the long history of intangible rights prosecutions holds that a breach of fiduciary duty, without misuse of one’s position for private gain, is an intangible rights fraud. The prosecutor argues, however, that United States v. Bronston, 658 F.2d 920 (2d Cir.1981), fills the bill. Bron-ston, a partner of a law firm (and, like Bloom, a politician in his spare time, as a member of the New York State Senate), occasionally represented Convenience and Safety Corporation, an aspirant to a large project that New York City planned to fund. Bronston proposed that the firm represent C&S in this endeavor, but the firm had earlier agreed to represent BusTop Shelters, a rival to C&S. The partner in charge of resolving conflicts told Bronston that the firm (and thus Bronston) could represent only BusTop. Bronston nonetheless did legal and lobbying work on behalf of C&S, attempting to influence New York’s decision with correspondence on his Senate letterhead, and was convicted of defrauding the law firm (and BusTop) of his honest services. Bronston misused both of his positions: he sent a letter on Senate stationery, and he converted to the benefit of C&S information received at the law firm, a step that meets 0’Hagan’s definition of fraud. See 658 F.2d at 924. Thus Bronston’s holding does not support the prosecutor’s position. Still, some of its language does so. The second circuit wrote that Bronston’s failure to tell BusTop and the law firm what he was doing to advance C&S’s cause was fraudulent, because he had a fiduciary duty to reveal that information. Id. at 927. A similar argument could be made here: perhaps Bloom had a duty to tell the City that he was urging Komed to subvert Chicago’s interests. Yet if failure to reveal one’s breach of fiduciary duty were the sort of fraud that permits a criminal conviction under § 1341, then every breach of fiduciary duty would be a crime (provided that the mails or telephone were used) — a position that the second circuit disavowed. Id. at 926. It is best, we think, to divorce the holding of Bronston from some of the broader language deployed to justify it. Bronston misused both his public position and information derived from his private position in a way that Bloom is not alleged to have done; Bronston does not validate the intangible rights aspect of Count I.
No one can be sure how far the intangible rights theory of criminal responsibility really extends, because it is a judicial gloss on § 1341. Congress told the courts in § 1346 to go right on glossing the mail fraud and wire fraud statutes along these lines. Given the tradition (which verges on constitutional status) against common-law federal crimes, and the rule of lenity that requires doubts to be resolved against criminalizing conduct, it is best to limit the intangible rights approach to the scope it held when the Court decided (and Congress undid) McNally. An employee deprives his employer of his honest services only if he misuses his position (or the information he obtained in it) *657for personal gain. Count I does not allege that Bloom did this and therefore does not state an offense under the intangible rights theory.
III
One other issue has so far gone unmentioned. Two months before dismissing the intangible rights aspects of Count I, the district judge severed Count I from the remaining counts of the indictment. The judge thought that Count I charges private misbehavior, while the remaining counts charge abuse of official powers (for example, accepting bribes). This implies that the counts were not properly joined under Fed. R.Crim.P. 8(a). Although the Criminal Appeals Act does not cover severance orders&emdash; and at all events the United States did not take a timely appeal from the order setting Count I for trial by itself&emdash;-the prosecutor asks us to review this decision anyway as an exercise of pendent appellate jurisdiction.
Abney v. United States, 431 U.S. 651, 662-63, 97 S.Ct. 2034, 52 L.Ed.2d 651 (1977), suggests that there is no such doctrine in criminal cases (at least when the main appeal is from an interlocutory rather than a final decision), and Swint v. Chambers County Commission, 514 U.S. 35, 43-51, 115 S.Ct. 1203, 131 L.Ed.2d 60 (1995), questions whether it exists even in civil eases. Since Smnt this court has not exercised pendent appellate jurisdiction in any case, civil or criminal. See United States v. Indianapolis Board of School Commissioners, 128 F.3d 507 (7th Cir.1997); Cleveland Hair Clinic, Inc. v. Puig, 104 F.3d 123 (7th Cir.1997); IDS Life Insurance Co. v. SunAmerica, Inc., 103 F.3d 524 (7th Cir.1996); In re Rimsat, Ltd., 98 F.3d 956, 964 (7th Cir.1996).
Several statutes, of which § 3731 is a good example, identify a limited group of orders that may be reviewed on interlocutory appeal. A discretionary appellate power to entertain additional issues would go a long way toward treating a list as an open-ended invitation. Although United States v. Zafiro, 945 F.2d 881, 885 (7th Cir.1991), affirmed, 506 U.S. 534, 113 S.Ct. 933, 122 L.Ed.2d 317 (1993), mentions the possibility of reviewing a severance order pendent to an appeal under § 3731, that statement was dictum under the definition we gave to that term in Part I above. Zafiro was an appeal by the defendant from a final decision. What we said about interlocutory prosecutorial appeals did not concern any issue in the case and was not informed by an adversarial presentation. Zafiro did not mention Abney and predates Swint; it therefore lacks authority on this subject. United States v. Van Engel, 15 F.3d 623, 629 (7th Cir.1993), which likewise states that pendent appellate jurisdiction in criminal cases is at least a possibility, is of little use to the prosecutor because it dismissed an effort by a defendant to present issues pendent to a prosecutor’s appeal under § 3731. What is more, Van Engel suggests that only extraordinary circumstances would justify pendent appellate jurisdiction in a criminal case.
Like the Supreme Court in Swint, 514 U.S. at 51, 115 S.Ct. 1203, we postpone final resolution. Any exercise of pendent (ancillary, supplemental) jurisdiction is discretionary with the tribunal. Given our conclusion that the district court correctly dismissed the portion of Count I that carries the intangible rights banner, it is unnecessary to take up an additional issue in order to afford the prosecutor complete relief, for the prosecutor is' not entitled to any relief at all. The appeal is dismissed to the extent it challenges the severance order, and the decision is otherwise affirmed.
