Task: songer_initiate

What follows is an opinion from a United States Court of Appeals. Your task is to identify what party initiated the appeal. For cases with cross appeals or multiple docket numbers, if the opinion does not explicitly indicate which appeal was filed first, assumes that the first litigant listed as the "appellant" or "petitioner" was the first to file the appeal. In federal habeas corpus petitions, consider the prisoner to be the plaintiff.

PER CURIAM.
This case was dismissed by the District Court apparently on the ground of res judicata, the court taking judicial notice of the previous case between the parties, the details of which are spelled out in Gullo v. Veterans Cooperative Housing Association, 1957, 101 U.S.App. D.C. 167, 247 F.2d 573.
In all its essential particulars, the present action is the same as that of the previous case, and the District Court correctly applied the doctrine of res judi-cata.
While the defense of laches was interposed, it is not necessary that we pass on that issue.
