What follows is an opinion from a United States Court of Appeals.
Intervenors who participated as parties at the courts of appeals should be counted as either appellants or respondents when it can be determined whose position they supported. For example, if there were two plaintiffs who lost in district court, appealed, and were joined by four intervenors who also asked the court of appeals to reverse the district court, the number of appellants should be coded as six.
When coding the detailed nature of participants, use your personal knowledge about the participants, if you are completely confident of the accuracy of your knowledge, even if the specific information is not in the opinion. For example, if "IBM" is listed as the appellant it could be classified as "clearly national or international in scope" even if the opinion did not indicate the scope of the business. 

Your task concerns the second listed appellant. The nature of this litigant falls into the category "private organization or association", specifically "business, trade, professional, or union (BTPU)". Your task is to determine what subcategory of private association best describes this litigant.

This is an appeal from the district court’s dismissal of the Government’s cause of action on the ground that it had no standing to bring an injunctive suit to prevent violation of section 504 of the Labor-Management Reporting and Disclosure Act, 29 U.S.C. § 504(a). The defendant, Clarence Jalas, is and has been business manager of the Chicago Moving Picture Machine Operators’ Union Local No. 110 for thirty years. On January 5, 1968, Jalas pleaded guilty to a violation of 29 U.S.C. § 186(b) (l), namely, that he knowingly accepted valuable common stock from an employer while serving as business manager of the local, which stock was delivered to him with the intent to influence his actions, decisions, and duties. Jalas was fined $500 for this misdemeanor offense. Subsequent to the conviction, Jalas’ name was placed in nomination for reelection as the local’s business manager and on February 1, 1968 he was reelected in an uncontested election. The action which is the subject of this appeal was brought on February 29 after Jalas’ conviction on January 5 and the February 1 election. The Government sought by its complaint to enjoin Jalas from running for and serving in the office of business manager on the basis of its averment that Jalas’ prior section 186(b) (1) conviction was a crime cognizable under section 504 (a)’s disqualification provisions. Since we are of the view that the Government has no standing to bring this action, it is unnecessary to decide whether the district court erred in concluding that Jalas’ violation of section 186(b) (1) constituted a conviction for bribery within the meaning of 29 U.S.C. § 504(a) and that consequently Jalas’ service as business manager is in violation of the latter section.
The Government urges that if it is denied the power to bring injunctive suits to prevent violations of the Land-rum-Griffin Act, the important national policy of keeping unions free from dishonest officials will be thwarted. Relying on the delay which invariably occurs before criminal prosecution under section 504 can be completed, the Government asserts that because its remedy at law is ineffective, equitable injunctive relief is essential to assure ethical standards are followed by union officials. Although we agree that enforcement delays and difficulties may exist under the present statutory scheme, this is a question which Congress with its special competence can best resolve. Assuming arguendo that Jalas’ taking office is a crime under section 504(a), nevertheless, none of the jurisdictional theories advanced by the Government allows us to grant the relief sought. Underlying our examination of the injunctive-relief issue is the doctrine that courts have no power to enjoin the commission of a crime. See 5 J. Moore, Federal Practice |J 38.24 [3], at 192 (2d ed. 1968). Historically this doctrine has been subject to exception in only three general situations: national emergencies, widespread public nuisances, and where a specific statutory grant of power exists. All the cases cited by the Government fall into one or another of these categories. For example In re Debs, 158 U.S. 564, 15 S.Ct. 900, 39 L.Ed. 1092 (1895), United States v. United Mine Workers of America, 330 U.S. 258, 67 S.Ct. 677, 91 L.Ed. 884 (1947), and United States v. Brotherhood of R. R. Trainmen, 96 F.Supp. 428 (N.D.Ill.1951), dealt with court-issued injunctions where acute national emergency situations which were unique necessitated such relief. The case of Hecht Co. v. Bowles, 321 U.S. 321, 64 S.Ct. 587, 88 L.Ed. 754 (1944), which the Government relies upon, concerned the use of an injunction which was expressly granted by statute. The Government does not cite any cases falling under the public nuisance rubric, but examples are set forth by the Supreme Court in the Debs case. It is our view that the facts of the instant case do not fall into any of the categories of exceptions to the general rule prohibiting issuance of an injunction against the commission of a crime.
It is revealing that the Government fails to rely on any specific jurisdictional provision of the federal labor laws other than section 504(a) which is patently a criminal statute contemplating proceeding by indictment or information. In fact throughout the Landrum-Griffin Act the only authority which is vested in the United States Attorney is enforcement of the criminal provisions of the Act. The statutory scheme bolsters our conclusion that the sole remedy for the complained-of-wrong is criminal prosecution.
The final argument advanced by the Government in support of its position on the standing question is that two other federal courts have found that they have jurisdiction to entertain actions for injunctive and declaratory relief under section 504. The Government relies specifically on Serio v. Liss, 189 F.Supp. 358 (D.N.J.1960), aff’d, 300 F.2d 386 (3d Cir. 1961), and Berman v. Local 107, 237 F.Supp. 767 (E.D.Pa.1964). In Berman a union official sought injunctive relief to force the union to place his name on the ballot for a forthcoming union election. By way of defense, the defendant union claimed that the plaintiff, Berman, had violated section 504(a). The Berman case is of no help to the Government. It does not hold that the Government may institute an injunctive action. Further, it did not involve, as here, a situation where, absent injunctive relief, the defendant allegedly would have committed a crime. Serio was a case involving a suit by a union officer seeking to enjoin the union president from removing the plaintiff from office. Although it is true that the Government was allowed to intervene on behalf of the defendant, in that case also the Government was not seeking to enjoin a union official from committing a crime.
Because the case law and statutory language do not compel a contrary conclusion, we hold that the Government has no standing to bring this injunctive action. There is no national emergency which warrants departing from the general rule prohibiting injunctions against the commission of criminal acts. If we were to hold otherwise and enjoin Jalas from holding office, we would necessarily be deciding in the context of a civil action an important criminal law question under section 504(a).
The judgment of the district court is affirmed.
