The delicate phrasing of the Clause and the ambiguity of the terms therein has inspired frequent academic debate. Though the Supreme Court has given much attention to the legal issues arising from this provision of the Constitution, many problematic issues remain unresolved. Critics argue that the standing requirements imposed by this Clause enable judges to avoid difficult issues, decide the merits of a case before the parties have had a fair opportunity to litigate, and avoid the necessity of applying law the judge finds distasteful.
