What is the constitutional minimum of standing in a personal injury action?

Over the years, our cases have established that the irreducible constitutional minimum of standing contains three elements: First, the plaintiff must have suffered an "injury in fact"--an invasion of a legally-protected interest which is (a) concrete and particularized; and (b) "actual or imminent, not 'conjectural' or 'hypothetical,' " Whitmore [v. Arkansas, 495 U.S. 149, 155, 110 S.Ct. 1717, 1722, 109 L.Ed.2d 135 (1990) ] (quoting Los Angeles v. Lyons, 461 U.S. 95, 102, 103 S.Ct. 1660, 1665, 75 L.Ed.2d 675 (1983)). Second, there must be a causal connection between the injury and the conduct complained of--the injury has to be "fairly ... trace[able] to the challenged action of the defendant, and not ... th[e] result [of] the independent action of some third party not before the court." Simon v. Eastern Kentucky Welfare Rights Org., 426 U.S. 26, 41-42, 96 S.Ct. 1917, 1926, 48 L.Ed.2d 450 (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, 96 S.Ct. at 1924, 1926.
