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.

In case No. 7180, appeal dismissed February 5, 1963, without written opinion, since the record conclusively shows that appellant is not now serving the sentence he attacks and relief under section 2255 is not available to him.
