Discrimination Lawsuit. A lawsuit is a civil action brought before a court of law in which a plaintiff, a party who claims to have received damages from a defendant's actions, seeks a legal or equitable remedy. The defendant is required to respond to the plaintiff's complaint.
In the United States, a citizen suit is a lawsuit by a private citizen to enforce a statute. Citizen suits are particularly common in the field of environmental law. Citizen suits come in three forms. First, a private citizen can bring a lawsuit against a citizen, corporation, or government body for engaging in conduct prohibited by the statute. For example, a citizen can sue a corporation under the Clean Water Act (CWA) for illegally polluting a waterway. Second, a private citizen can bring a lawsuit against a government body for failing to perform a non-discretionary duty.
