Whether the Sixth Circuit erred in granting habeas relief based on an alleged misapplication of its own circuit precedent

QUESTIONS PRESENTED 1. AEDPA generally prohibits courts from awarding habeas relief to state prisoners. It 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.” 28 U.S.C. §2254(d)(1). Did the Sixth Circuit err by granting habeas relief based on an alleged misapplication of its own circuit precedent? 2. If 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, must a court hold the hearing regardless?
