What follows is an opinion from a United States Court of Appeals. Your task is to identify the type of district court decision or judgment appealed from (i.e., the nature of the decision below in the district court).

Opinion:
BOMAR v. KEYES et al.
No. 20, Docket 21010.
United States Court of Appeals Second Circuit.
Oct. 8, 1948.
Willie M. Bomar, pro se.
John P. McGrath, Corp. Counsel, and Arthur H. Kahn, both of New York City,, for appellee.
Before L. HAND, Chief Judge, and SWAN and CHASE, Circuit Judges.
PER CURIAM.
In Bomar v. Keyes we decided that the complaint should be dismissed against the City, and the plaintiff thereafter applied for certiorari which was denied on November 18, 1947. On December 17, 1947, Judge Rifkind entered an order dismissing the complaint against the City in conformity with our opinion, although meanwhile, the plaintiff had petitioned for rehearing, and that petition was not denied until December 22, 1947. This is an appeal from Judge Rifkind’s order of December 17, 1947, entered upon our m'andate.
The order, even if it were wrong (which we do not even remotely suggest) is not appealable. Hohorst v. Hamburg Co.; National Bank of Rondout v. Smith; Bush v. Leach; Shultz v. Manufacturers & Traders Trust Co. The appeal must be dismissed.
Appeal dismissed.
2 Cir., 162 F.2d 136.
