Standing
A plaintiff's right to bring suit, requiring injury-in-fact, causation, and redressability.
Standing is part of the Article III case-or-controversy requirement. The three constitutional elements are injury-in-fact, a causal connection between the injury and the defendant’s conduct, and a likelihood that a favorable decision will redress the injury. Prudential standing rules add further limits (e.g., no third-party standing absent special circumstances).
