Standing (law)
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:
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.
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.
