Opinion of the Court
Rights Organization, 426 U. S. 26, 41-42 (1976). Third, it must be "likely," as opposed to merely "speculative," that the injury will be "redressed by a favorable decision." Id., at 38, 43.
The party invoking federal jurisdiction bears the burden of establishing these elements. See FW/PBS, Inc. v. Dallas, 493 U. S. 215, 231 (1990); Warth, supra, at 508. Since they are not mere pleading requirements but rather an indispensable part of the plaintiff's case, each element must be supported in the same way as any other matter on which the plaintiff bears the burden of proof, i. e., with the manner and degree of evidence required at the successive stages of the litigation.

And at the final stage, those facts (if controverted) must be "supported adequately by the evidence adduced at trial." Gladstone, supra, at 115, n. 31.
When the suit is one challenging the legality of government action or inaction, the nature and extent of facts that must be averred (at the summary judgment stage) or proved (at the trial stage) in order to establish standing depends considerably upon whether the plaintiff is himself an object of the action (or forgone action) at issue.
