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.
Indicted for, and convicted of, a violation of Section 2421, Title 18 U.S.C., transporting a woman in interstate commerce for the purpose of practicing prostitution, defendant has appealed. Here, putting forward four specifications of error, appellant insists that they are well taken, and, because they are, the judgment must be reversed.
We cannot agree. Indeed, we think it plain that, varying in degree from the inexcusably frivolous claim of point A of the first specification, that the proof fails to show that the so-called victim was a woman, to the little less frivolous one, that the woman could not, because of the claimed marriage to defendant, testify against him in the case, all of the claims of error are wanting in substance and the judgment must be affirmed.
Affirmed.
