Whether a federal habeas court contravenes this Court's precedent when it evaluates the merits of a petitioner's claim without regard for the state court's rules for evaluating habeas petitions

QUESTION PRESENTED In Brumfield v. Cain, 135 S. Ct. 2269, 2276, 2282 (2015), this Court made clear that 28 U.S.C § 2254(d)(2) is satisfied when a state court denies an evidentiary hearing where the petitioner’s allegations and evidence on his constitutional claim are sufficient to obtain a hearing under state law. Does a federal habeas court contravene this Court’s precedent when it evaluates the merits of a petitioner’s claim without regard for the state court’s rules for evaluating habeas petitions? i
