Model answer
Introduction. Res judicata rests on two maxims: nemo debet bis vexari pro una et eadem causa (no one should be vexed twice for the same cause) and interest reipublicae ut sit finis litium (it is in the public interest that litigation ends). Section 11 CPC codifies it.
Essentials. (1) The matter directly and substantially in issue in the later suit was directly and substantially in issue in the former suit; (2) the former suit was between the same parties or those claiming under them; (3) they litigated under the same title; (4) the former court was competent to try the later suit; and (5) the matter was heard and finally decided.
Constructive res judicata. Explanation IV to Section 11 provides that any matter which might and ought to have been made a ground of attack or defence in the former suit is deemed to have been directly and substantially in issue. It prevents a party from splitting its pleas across suits. Example: A sues B for possession on the basis of a sale deed and loses. A cannot file a fresh suit on the basis of adverse possession that existed when the first suit was filed.
Case law. Satyadhyan Ghosal v. Deorajin Debi (1960) applied the principle between different stages of the same proceeding. Forward Construction Co. v. Prabhat Mandal (1986) explained “might and ought”. The doctrine also applies to writ petitions (Daryao v. State of U.P., 1961), though not to habeas corpus.
Conclusion. Res judicata, including its constructive form, secures finality and prevents abuse of process, while exceptions such as fraud, lack of jurisdiction and pure questions of law on jurisdiction keep it fair.
