A case in which the Court decided that the district court's denial of petitioner's request for "reasonably necessary" investigative and related services under 18 U.S.C. § 3599(f) to prove that he was entitled to federal habeas relief was a judicial decision subject to appellate review under the standard jurisdictional provisions; and that the U.S. Court of Appeals for the 5th Circuit applied the wrong legal standard in affirming the district court's denial of petitioner's § 3599(f) request.
