Shoop v. Cunningham

Issue: (1) Whether the U.S. Court of Appeals for the 6th Circuit erred by granting habeas relief based on an alleged misapplication of its own circuit precedent under the Antiterrorism and Effective Death Penalty Act, which generally prohibits courts from awarding habeas relief to state prisoners but lifts that prohibition with respect to prisoners in custody because of a state-court ruling that was "contrary to, or involved an unreasonable application of, clearly established Federal law, as determined by the Supreme Court of the United States"; and (2) whether, when the requirements for a federal evidentiary hearing are otherwise satisfied but Federal Rule of Evidence 606(b)(1) forbids considering the only evidence supporting an evidentiary hearing, a court must hold the hearing regardless.
