Definition
Res Judicata, Latin for “a matter adjudged,” is a judicial principle that aims to prevent legal disputes from being relitigated once they have been resolved by a competent court with a final judgment. This doctrine maintains the integrity and finality of court decisions by ensuring that parties cannot bring the same issue before court more than once if it involves the same cause of action and the same parties.
Examples
- Federal District Court Example:
- Two parties litigate a contractual dispute in one federal district court, which results in a final judgment favoring Party A. Under the principle of res judicata, Party B cannot bring a lawsuit on the same contractual dispute in another federal district court.
- State Court Example:
- Party X sues Party Y in state court for personal injury damages and receives a final judgment. Party Y cannot subsequently file a new lawsuit on the same incident with similar claims in another state court.
- Multiple Jurisdictions Example:
- An employee sues an employer for wrongful termination in state court and loses. The employee cannot then file a related federal lawsuit on the basis of the same termination seeking similar remedies.
