What follows is an opinion from a United States Court of Appeals. Your task is to identify the federal agency (if any) whose decision was reviewed by the court of appeals. If there was no prior agency action, choose "not applicable".

PER CURIAM:
In its consideration of this state prisoner’s habeas petition, the district court neither held an evidentiary hearing nor had before it the record of petitioner’s trial, or at least the state record was not introduced into evidence. That court has thus failed to conduct its required independent inquiry into the petitioner’s constitutional claims. See Townsend v. Sain, 1963, 372 U.S. 293, 83 S.Ct. 745, 9 L.Ed.2d 770. Its judgment is therefore vacated and the case is remanded for further consideration.
. The matter was handled by a magistrate whose findings, conclusions and recommendation were adopted by the district court. The clerk of the district court has advised this court that all state court materials filed as exhibits in district court were transmitted to this court. The state trial record is not among these exhibits.
