How it applies
Common Examples
6
Generalized Interest Insufficient
Charlotte Chung files a citizen suit under a federal environmental statute alleging that the government has failed to enforce reporting requirements against all regulated facilities nationwide. She identifies no particular harm to herself or her property. The court dismisses the action because her asserted interest amounts to a generalized grievance shared equally by all citizens.
Notice Requirement Bars Suit
Catherine Carter sends a citizen suit notice to a chemical plant operator alleging ongoing violations of hazardous-chemical inventory rules. She files the complaint only thirty days later. The court dismisses the action because the statute requires sixty days' notice before suit may proceed.

Taxpayer Standing Rejected
Craig Caldwell brings a citizen suit challenging the government's failure to publish certain agency expenditures as required by statute. He alleges only his status as a taxpayer with an interest in lawful government accounting. The court holds that this undifferentiated interest does not confer standing.

Ongoing Violation Supports Relief
Caleb Chang, a member of an environmental group, files a citizen suit against a manufacturing facility for repeated permit violations that continue to affect a nearby river. The court finds standing because the violations are ongoing and the requested injunctive relief would redress the group's members' injuries.

State Standing Recognized

Common questions
Frequently Asked
4
Must a plaintiff in a citizen suit demonstrate a concrete and particularized injury?+
Yes. Even when a statute authorizes citizen suits, Article III requires the plaintiff to show an injury in fact that is concrete and particularized rather than a generalized grievance shared by all citizens.
Can Congress create standing for citizen suits by statute alone?+
No. Congress may authorize citizen suits, but it cannot confer Article III standing when the plaintiff lacks a concrete and particularized injury.
Does a citizen suit require prior notice to the alleged violator?+
Many environmental statutes impose a sixty-day notice requirement before a citizen suit may be filed. Failure to provide the required notice results in dismissal.
When does a citizen suit for past violations become moot?+
A citizen suit seeking injunctive relief for wholly past violations is moot once the violations cease and there is no reasonable likelihood of recurrence.
