Abstract: The application of the doctrine of standing has become less and less predictable since the Supreme Court’s adoption of a tripartite test for standing in the 1970s. Professor Fallon analyzes the Court’s decisions in standing cases in order to discern patterns in the Court’s application of this test. Fallon concludes that the Supreme Court and legal scholars should embrace the fragmentation of the doctrine of standing and look to discernable patterns in the cases to find general rules of application for different contexts.
