Does a state court's determination that a claim lacks merit preclude federal habeas relief?

A state court's determination that a claim lacks merit precludes federal habeas relief so long as fairminded jurists could disagree on the correctness of the state court's decision. Harrington v. Richter, 562 U.S. -, 131 S.Ct. 770, 786 (2011). Even a strong case for relief does not render the state court's conclusions unreasonable. Id. To obtain federal habeas relief, a state prisoner must show that the state court's ruling on a claim was "so lacking in justification that there was an error well understood and comprehended in existing law beyond any possibility for fairminded disagreement." Id. at 786-87.
