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.
Frivolous acts can include filing the lawsuit itself, a baseless motion for a legal ruling, an answer of a defendant to a complaint which does not deny, contest, prove, or controvert anything, or an appeal which contains not a single arguable basis (by any stretch of the imagination) for the appeal.
