Res Judicata

rez joo-di-KAH-tah Latin: 'a matter already judged'

Definition

The legal principle that a matter once finally decided by a competent court cannot be re-litigated between the same parties.

Detailed Explanation

Res judicata (also known as claim preclusion) is a fundamental doctrine that prevents the same parties from re-litigating issues that have been finally decided. The principle serves the dual purpose of ensuring finality of judicial decisions and preventing harassment of defendants through repeated lawsuits.

In Indian law, the doctrine is codified under Section 11 of the Code of Civil Procedure, 1908. The section provides that no court shall try any suit or issue in which the matter directly and substantially in issue has been directly and substantially in issue in a former suit between the same parties, or parties under whom they or any of them claim, litigating under the same title.
