Abie State Bank v. Bryan

In Abie State Bank v. Bryan, 282 U. S. 765 (1931), the Supreme Court of Nebraska had rejected a federal constitutional claim, relying in part on the state law doctrine of laches. Writing for the Court in response to the Nebraska Governor's argument that the Court should not accept jurisdiction because laches provided an independent ground for decision, Chief Justice Hughes concluded that this Court must ascertain for itself whether the asserted nonfederal ground independently and adequately supported the judgment "in order that constitutional guaranties may appropriately be enforced." Id., at 773.
