What is the test for standing in a personal injury action?

The court then turned to the threshold and, in its opinion, decisive issue, i.e., 'whether plaintiffs have standing to bring this suit.' Standing was then tested by 'the two-pronged test' namely, have the plaintiffs suffered or will they suffer an 'injury in fact' and are they 'within the zone of interests protected by the relevant statute.' The court was also mindful of the necessity that 'litigants maintain a personal stake in the outcome of the controversies they present.' DeFunis v. Odegaard, 416 U.S. 324, 94 S.Ct. 1704, 40 L.Ed.2d 164 (1974).
