*Section 11 of Civil Procedure Code, 1908*

Res Judicata means a thing decided.

Res Judicata is the Latin term for “a matter judged“,

It can apply in a case where has be there has been a final judgment and it is no longer subject to appeal;

It can also be used to bar (stop, block) continued litigation of a case on same issues between the same parties.


The doctrine includes two related concepts – Claim preclusion and Issue preclusion.

Claim Preclusion

Claim preclusion focuses on baring a suit from being brought again on a legal cause of action that has already been finally decided between the parties.

Issue Preclusion

Issue preclusion bars the re-litigation of factual issues that have already been necessarily determined by a judge as a part of an earlier claim.


Doctrine of res judicata is based on three maxims-

1. Nemo debet bis vexari pro una et eadem causa – It means no man shall be punished twice for the same offence.

2. Interest Reipublicae Ut Sit Finis Litium – It means it is in the interest of the state that there should be an end to litigation. or Litigation must come to an end.

3. Res Judicata Pro Veritate Accipitur – It means that a judicial decision must be accepted as correct.


Nemo bis punitur pro eodem delicto also means almost the same as Nemo debet bis vexari pro una et eadem causa.
