A statutory mechanism allowing private individuals to enforce compliance with federal laws by suing alleged violators or agencies in federal court. The mechanism requires plaintiffs to satisfy Article III standing by alleging a concrete and particularized injury fairly traceable to the defendant's conduct and redressable by a favorable decision. Congress may authorize such suits but cannot eliminate the constitutional injury requirement.

Residents from several states led by Maria Lopez sued the National Climate Agency alleging its emissions policy would gradually worsen landscapes and weather everywhere. They asserted standing solely as citizens and nature enthusiasts without identifying any specific parcel or recreational site they used that would be imminently affected. The court dismissed the action because the asserted harm was shared equally by the public at large.
Citizens for a Better Environment sued Steel Co. under the Emergency Planning and Community Right-to-Know Act for failure to file past reports. The group sought only civil penalties payable to the government and had no ongoing violation to redress. The court held that the requested relief would not redress any injury to the plaintiffs themselves.
Taxpayer William Richardson sued to compel disclosure of CIA expenditures under the Statement and Account Clause. He alleged only that the public had a right to know how funds were spent and claimed no personal financial or other concrete harm. The court dismissed the suit as presenting a generalized grievance shared by all citizens.
Friends of the Earth sued Laidlaw Environmental Services alleging ongoing permit violations that impaired the use and enjoyment of a river by its members. Members submitted affidavits showing they lived near the river and would resume recreational activities once discharges ceased. The court found the affidavits sufficient to establish redressable injury supporting standing.
Massachusetts sued the EPA to compel regulation of motor vehicle emissions contributing to climate change. The state alleged that rising sea levels would imminently inundate its coastal property and that EPA's refusal to regulate caused that injury. The court held that the state's quasi-sovereign interest and particularized coastal harm satisfied standing requirements.
Pennsylvania sued Union Gas under CERCLA to recover costs of cleaning up a hazardous waste site. The state alleged it had incurred concrete response costs traceable to the company's prior ownership. The court addressed whether the Eleventh Amendment barred the suit but confirmed that the state's direct financial injury satisfied standing for the citizen-suit provision.
No. Article III requires a concrete and particularized injury in fact even when a statute authorizes citizen suits. A bare interest in having the government follow the law is a generalized grievance that does not satisfy the injury requirement.

A generalized grievance is an injury shared in substantially equal measure by all citizens, such as concern that the government is not following the law. A particularized injury affects the plaintiff in a personal and individual way, such as imminent harm to property or recreational use the plaintiff actually enjoys.
…those limitations if, at the behest of Congress and in the absence of any showing of concrete injury, we were to entertain citizen suits to vindicate the public's nonconcrete interest in the proper administration of the laws.

Yes, when the harm is concrete and particularized. A plaintiff who regularly uses a specific river and shows imminent degradation of that river from the defendant's conduct can establish injury in fact. Allegations of general worsening of landscapes or weather for everyone do not suffice.

No. Noneconomic harms such as aesthetic or recreational injury qualify when they are concrete and particularized. The key defect in many citizen suits is lack of particularization rather than absence of monetary harm.

No. A bare procedural violation without any real risk of harm to the plaintiff does not satisfy the injury-in-fact requirement. The plaintiff must still demonstrate a concrete and particularized injury traceable to the violation.
