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 appeal was submitted to the Court after oral argument at the November term. Petitioner, then in the custody of the State of Kansas, sought relief by way of Writ of Error Coram Nobis from a judgment of conviction for a federal offense and the sentence imposed pursuant to such judgment upon claim that the federal sentence, although fully served, formed the basis for his retention by the State of Kansas. We are now informed that petitioner has since been released from state custody pursuant to a Writ of Habeas Corpus issued by the Kansas state court. The issues of this appeal are thus moot and the appeal is dismissed.
