Res judicata has three general elements: re-litigation, same cause of action, and same or closely related parties. Res judicata prevents a party from bringing a claim once that particular claim has been subjected to a final judgment in some previous lawsuit. Re-litigation applies to a new lawsuit brought in any court, not just the one responsible for earlier judgment. This piece of res judicata is considered the most straightforward of the doctrine.
Similarly, res judicata prevents a party from bringing the same claim or cause of action against the defendant once a final judgment has been made. The term ‘claim’ is the legal demand for compensation, while ’cause of action’ is the set of elements that allow for legal remedy.
