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 "cabinet level department". Your task is to determine which specific federal government agency best describes this litigant.

Opinion:
James P. MITCHELL, Secretary of Labor, United States Department of Labor, Appellant, v. WELCOME WAGON, Inc., Appellee.
No. 12525.
United States Court of Appeals Sixth Circuit.
April 19, 1956.
Stuart Rothman, Bessie Margolin, and Sylvia S. Ellison, Washington, D. C., Jeter S. Ray, Nashville, Tenn., for appellant.
Robert H. Stickley, Lucius E. Burch, Jr., Memphis, Tenn., for appellee.
Before ALLEN, McALLISTER, and STEWART, Circuit Judges.
PER CURIAM.
The above cause coming on to be heard on the record, the briefs of the parties, and the argument of counsel in open court, and the court being duly advised.
Now, therefore, it is ordered, adjudged, and decreed that the judgment be and is hereby affirmed for the reasons set forth in the findings of fact and conclusions of law of the district court, 139 F.Supp. 674.
. Because of factual differences between the instant case and Mitchell v. Joyce Agency, 7 Cir., 211 F.2d 241, the citation by the district court, in its conclusions of law, of the latter case, reversed in 348 U.S. 945, 75 S.Ct. 436, 99 L.Ed. 740, in no way affects the determination of the case.
