Premo v. Moore, 562 U.S. ___ (2011), is a United States Supreme Court case involving the right of individuals to federal habeas corpus relief on state-law claims. In a unanimous ruling, the court held that habeas relief may not be granted with respect to any claim a state-court has found on the merits unless the state-court decision denying relief involves an "unreasonable application" of "clearly established federal law, as determined by" the Court.
