¶1Solicitor General Perlman argued the cause for the United States. With him on the brief were Assistant Attorney General Quinn, Philip Elman, Robert S. Erdahl and Irving S. Shapiro.
¶2*78Bernard Margolius argued the cause for appellee. With him on the brief was Joseph B. Danzansky.
¶4delivered the opinion of the Court.
¶5On Feb. 27, 1946, the Price Administrator filed a petition, in the District Court for the District of Columbia, to institute criminal contempt proceedings against appel-lee. The petition charged appellee with having made numerous sales of used cars at over-ceiling prices in violation of an injunction previously issued by the District Court. A rule to show cause was issued, but was dismissed on motion of the appellee, on the ground that he was entitled to immunity under § 202 (g) of the Emergency Price Control Act from prosecution for the transactions upon which the petition was founded. 68 F. Supp. 53.
¶6The Government brought this appeal, under the provisions of the Criminal Appeals Act,1 to review the decision of the District Court. The main issue is the same as that presented in the companion case, Shapiro v. United States, ante, p. 1, but two additional minor questions are raised:
¶71. Appellee urges that the appeal was not properly taken by the United States because the Government was not a party to the proceedings in the District Court. The record shows, however, that the litigation was instituted in that court by a petition of the OPA District Enforcement Attorney on behalf of the Price Administrator. When the rule to show cause was issued, the court appointed the United States Attorney and the OPA District Enforcement Attorney as “attorneys to prosecute *79the criminal charges contained in the petition filed herein on behalf of the Court and of the United States.” See Rule 42 (b) of the Rules of Criminal Procedure, 327 U. S. 865-66. Thus the United States was, in any relevant sense, a party to the proceedings, and the appeal was properly brought under the Criminal Appeals Act. See United, States v. Goldman, 277 U. S. 229, 235 (1928); Ex parte Grossman, 267 U. S. 87, 115 et seq. (1925).
¶82. The Government mentions a further consideration, not involved in the Shapiro case. The record does not state that the appellee was sworn and produced the records under oath, a condition precedent to the attainment of immunity under a 1906 Amendment, 49 U. S. C. § 48, to the Compulsory Testimony Act of 1893. It is unnecessary to consider this contention both because it does not appear to have been duly raised in the court below, and because the grounds considered and the views set forth in our opinion in the Shapiro case suffice to dispose of this appeal.
¶9The decision of the District Court is reversed and the case remanded for further proceedings.
¶10Reversed.
