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 first listed appellant. The nature of this litigant falls into the category "federal government (including DC)", specifically "other, not listed, not able to classify". Your task is to determine which specific federal government agency best describes this litigant.

Before GRONER, Chief Justice, and WILBUR K. MILLER and PRETTY-MAN, Associate Justices.
PER CURIAM.
The' Price Administrator, who was appellant’s predecessor as a party to this case, brought a civil action in the District Court praying for an injunction and for damages. Trial was had. On December 11, 1945, a memorandum opinion was filed by the District Court in which the Court stated, inter alia: “Damages denied. Petition for injunction granted.” Thereafter on January 3, 1946, a final decree was entered which, after reciting that the parties had agreed that the memorandum opinion should serve as findings of fact and conclusions'of law, enjoined appellee from selling garments above ceiling prices, but the decree contained no provision with respect to the claim for damages. On March 25, 1946, the Price Administrator appealed “from that portion of the judgment of this Court which denied the Administrator relief under Section 205(e) [i. e., damages] of. the Emergency Price Control Act of 1942 as amended, 50 U.S.C.A.Appendix, § 925(e), entered on the. 3rd day of January 1946, in favor of Jo Van Der Loo against Paul A. Porter’s predecessor as Administrator of the Office of Price Administration, Chester Bowles.” ’■
There has been no judgment entered upon the claim for damages. Cf. Rule •54, Federal Rules of Civil Procedure, 28 U.S.C.A. following section 723c. This appeal consequently is premature and must be dismissed. The case will be remanded to the District Court for the entry of judgment on the claim for damages. St. Louis Amusement Company v. Paramount Film Distributing Corporation, 8 Cir., 156 F.2d 400; In re D’Arcy, 3 Cir., 142 F.2d 313.
