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)". Your task is to determine which category of federal government agencies and activities best describes this litigant.

Opinion:
UNITED STATES v. AKERMAN, Judge.
No. 6769.
Circuit Court of Appeals, Fifth Circuit.
Oct. 31, 1932.
W. P. Hughes, U. S. Atty., of Jacksonville, Fla.
Before BRYAN, FOSTER, and SIBLEY, Circuit Judges.
SIBLEY, Circuit Judge.
Paul Antinori was on June 10, 1929, sentenced to four years’ imprisonment, but his sentence was suspended, and he w;as placed on probation under the Probation Act (18. USCA §§ 724-727). On June 18„ 1931, his probation was revoked after a hearing, and he was resenteneed to a reduced term of imprisonment of twelve months. The United States appealed from the judgment in so far as it reduced the original sentence, but the jurisdiction of the District Court on revoking probation to impose a new and lesser sentence was upheld upon the words of 18 USCA § 725: “Thereupon the court may revoke the probation or the suspension of sentence, and may impose any sentence which might originally have been imposed.” United States v. Antinori (C. C. A.) 59 F.(2d) 171. The District Court duly entered the mandate of affirmance on July 18, 1932, and directed the marshal to imprison Antinori for the unexpired portion of his twelve months sentence. On the same day, however, after a showing touching Antinori’s ill health, the District Court undertook to amend the sentence of June 18, 1931, to read imprisonment for one hour only. A mandamus is sought from this court to require execution of the judgment which it had affirmed. The answer of the District Judge discloses that he is of opinion that the appeal from the judgment of June 18, 1931, kept the term of the District Court' open as respects this ease until the mandate was entered on July 18,1932, and that thereupon he had the same jurisdiction to amend the judgment as he would have had immediately after and within the term at which it was rendered, in accordance with the case of United States v. Benz, 282 U. S. 304, 51 S. Ct. 113, 75 L. Ed. 354. This view is, we. think, ’ erroneous. When probation was revoked and “such sentence imposed as might, originally have been imposed,” the provisions of the Probation Act were exhausted. The sentence then imposed was final in the) same way that all criminal sentences were before that law was passed. While within the breast of the court during the term, that term of the District Court expired long before July 18, 1932. The appeal did not extend it. On affirmance the judgment stood unalterable by the District Court. Realty Acceptance Corp. v. Montgomery, 284 U. S. 547, 52 S. Ct. 215, 76 L. Ed. 476; United States v. Mayer, 235 U. S. 55, 35 S. Ct. 16, 59 L. Ed. 129. Commutation, if any, must come through the pardoning power.
It is ordered that a, copy of this opinion bo certified to the District Judge.
