May a federal habeas court grant relief based solely on its conclusion that the Brecht test is satisfied, or must the court also find that the state court's Chapman application was unreasonable under § 2254(d)(1)

QUESTION PRESENTED In Brecht v. Abrahamson, 507 U.S. 619 (1993), the Court held that the test for determining whether a constitutional error was harmless on habeas review is whether the defendant suffered “actual prejudice.” Congress later enacted 28 U.S.C. § 2254(d)(1), which prohibits habeas relief on a claim that was adjudicated on the merits by a state court unless the adjudication “resulted in a decision that was contrary to, or involved an unreasonable application of, clearly established Federal law.” Although the Court has held that the Brecht test “subsumes” § 2254(d)(1)’s requirements, the Court declared in Davis v. Ayala, 576 U.S. 257, 267 (2015), that those requirements are still a “precondition” for relief and that a state-court harmlessness determination under Chapman v. California, 386 U.S. 18 (1967), still retains “significance” under the Brecht test. The question presented is: May a federal habeas court grant relief based solely on its conclusion that the Brecht test is satisfied, as the Sixth Circuit held, or must the court also find that the state court’s Chapman application was unreasonable under § 2254(d)(1), as the Second, Third, Seventh, Ninth, and Tenth Circuits have held?
