In law, standing or locus standi is the term for 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. Standing exists from one of three causes:
(1) The party is directly subject to an adverse effect by the statute or action in question, and the harm suffered will continue unless the court grants relief in the form of damages or a finding that the law either does not apply to the party or that the law is void or can be nullified. This is called the “something to lose” doctrine, in which the party has standing because they directly will be harmed by the conditions for which they are asking the court for relief.
(2) The party is not directly harmed by the conditions by which they are petitioning the court for relief but asks for it because the harm involved has some reasonable relation to their situation, and the continued existence of the harm may affect others who might not be able to ask a court for relief. In the United States, this is the grounds for asking for a law to be struck down as violating the First Amendment, because while the plaintiff might not be directly affected, the law might so adversely affect others that one might never know what was not done or created by those who fear they would become subject to the law the so-called “chilling effects” doctrine.
(3) The party is granted automatic standing by act of law. Under some environmental laws in the United States, a party may sue someone causing pollution to certain waterways without a federal permit, even if the party suing is not harmed by the pollution being generated. The law allows them to receive a portion of any fines collected by the government from their violation of law. In some U.S. states, a person who believes a book, film or other work of art is obscene may sue in their own name to have the work banned directly without having to ask a District Attorney to do so.
I understand standing, and I think the courts have illegally ruled against it. Illegal because they violated the civil rights of the persons bringing the suits to have their cases heard.
