What is another word for res judicata?
Pronunciation: [ɹˈɛz d͡ʒˌuːdɪkˈɑːtə] (IPA) 
Res judicata is a Latin term used in law that refers to a legal matter that has been decided by a court and cannot be retried. Synonyms for this term include "claim preclusion," "issue preclusion," and "collateral estoppel." Claim preclusion refers to the principle that a final judgment on the merits of a claim precludes re-litigation of the same claim. Issue preclusion prevents a party from re-litigating the same issue in a different case. Collateral estoppel is similar to issue preclusion, but it refers specifically to the effect of a prior judgment on a different cause of action involving the same parties. While these terms have slightly different nuances, they are all commonly used to refer to the idea that a legal matter has been decided and cannot be tried again.
