Standing

Overview
In the common law, and under many statutes, standing )or locus standi) is the ability of a party to demonstrate to the court sufficient connection to and harm from the law or action challenged to support that party's participation in the case. In the United States, for example, a person cannot bring a suit challenging the constitutionality of a law unless the plaintiff can demonstrate that the plaintiff is (or will imminently be) harmed by the law. Otherwise, the court will rule that the plaintiff "lacks standing" to bring the suit, and will dismiss the case without considering the merits of the claim.

U.S. law
In United States law, the U.S. Supreme Court has stated, "[i]n essence the question of standing is whether the litigant is entitled to have the court decide the merits of the dispute or of particular issues".

There are a number of requirements that a plaintiff must establish in order to have standing before a federal court. Some are based on the case or controversy requirement of the judicial power of Article Three of the U.S. Constitution, § 2, cl.1: "The Judicial Power shall extend to all Cases . . .[and] to Controversies. . . ."

The requirement that a plaintiff have standing to sue is a limit on the role of the judiciary and the law of Article III standing is built on the idea of separation of powers. Federal courts may exercise power only "in the last resort, and as a necessity".

Constitutional requirements
There are three constitutional standing requirements:


 * 1) Injury: The plaintiff must have suffered or imminently will suffer injury &mdash; an invasion of a legally protected interest which is concrete and particularized. The injury must be actual or imminent, distinct and palpable, not abstract. This injury could be economic as well as non-economic.


 * 1) Causation: There must be a causal connection between the injury and the conduct complained of, so that the injury is fairly traceable to the challenged action of the defendant and not the result of the independent action of some third party who is not before the court.


 * 1) Redressability: It must be likely, as opposed to merely speculative, that a favorable court decision will redress the injury.

Prudential limitations
Additionally, there are three major prudential (judicially-created) standing principles. Congress can override these principles via statute, but U.S. Supreme CourtCongress|Congress]] cannot change the three constitutional standing requirements.


 * 1) Prohibition of Third Party Standing: A party may only assert his or her own rights and cannot raise the claims of a third party who is not before the court. Exceptions exist where the third party has interchangeable economic interests with the injured party, or a person unprotected by a particular law sues to challenge the oversweeping of the law into the rights of others, for example, a party suing that a law prohibiting certain types of visual material may sue because the First Amendment]] rights of others engaged in similar displays might also be damaged as well as those suing. Additionally, third parties who don't have standing may be able to sue under the next-friend doctrine if the third party is an infant, mentally handicapped, or not a party to a contract.


 * 1) Prohibition of Generalized Grievances: A plaintiff cannot sue if the injury is widely shared in an undifferentiated way with many people. For example, the general rule is that there is no federal taxpayer standing, as complaints about the spending of federal funds are too remote from the process of acquiring them. Such grievances are ordinarily more appropriately addressed in the representative branches.


 * 1) Zone of Interest Test: There are in fact two tests used by the U.S. Supreme Court for the Zone of Interest &mdash;


 * 1) Zone of Injury &mdash; The injury is the kind of injury that Congress expected might be addressed under the statute.


 * 1) Zone of Interests &mdash; The party is within the zone of interest protected by the statute or constitutional provision.

Recent development of the doctrine
In 1984, the Supreme Court reviewed and further outlined the standing requirements in Allen v. Wright, a major ruling concerning the meaning of the three constitutional standing requirements of injury, causation, and redressability.

In the suit, parents of black public school children alleged that the Internal Revenue Service was not enforcing standards and procedures that would deny tax-exempt status to racially discriminatory private schools. The Court found that the plaintiffs did not have the standing necessary to bring suit. Although the Court established a significant injury for one of the claims, it found the causation of the injury (the nexus between the defendant’s actions and the plaintiff’s injuries) to be too attenuated. "The injury alleged was not fairly traceable to the Government conduct respondents challenge as unlawful".

In another major standing case, Lujan v. Defenders of Wildlife, the Supreme Court elaborated on the redressability requirement for standing. The case involved a challenge to a rule promulgated by the Secretary of the Interior interpreting §7 of the Endangered Species Act of 1973 (ESA). The rule rendered §7 of the ESA applicable only to actions within the United States or on the high seas. The Court found that the plaintiffs did not have the standing necessary to bring suit, because no injury had been established. The injury claimed by the plaintiffs was that damage would be caused to certain species of animals and that this in turn injures the plaintiffs by the reduced likelihood that the plaintiffs would see the species in the future. The court insisted though that the plaintiffs had to show how damage to the species would produce imminent injury to the plaintiffs. The Court found that the plaintiffs did not sustain this burden of proof. "The 'injury in fact' test requires more than an injury to a cognizable interest. It requires that the party seeking review be himself among the injured".

Beyond failing to show injury, the Court found that the plaintiffs failed to demonstrate the standing requirement of redressability. The Court pointed out that the respondents chose to challenge a more generalized level of Government action, "the invalidation of which would affect all overseas projects". This programmatic approach has "obvious difficulties insofar as proof of causation or redressability is concerned".
