Ivan Rathinam v. Milan Joseph
Background
The respondent was born to a woman during her subsisting marriage to one Mr. Raju Kurian, whose name was recorded as the father in the birth register. After the woman divorced Mr. Kurian, she sought to have the appellant's name substituted as the child's father, alleging an extramarital relationship, and the respondent filed a civil suit seeking a declaration of paternity as well as a maintenance petition under Section 125 CrPC against the appellant. Over roughly two decades, the matter went through multiple rounds of litigation, and a civil appellate court had already conclusively held in 2011 (a decision never further appealed) that the presumption of legitimacy in favour of Mr. Kurian's fatherhood stood unrebutted. Despite this, the Family Court later revived the maintenance petition against the appellant, and the Kerala High Court upheld that revival, prompting this appeal to the Supreme Court.
Decision Breakdown
The Supreme Court held that legitimacy under Section 112 of the Indian Evidence Act continues to determine paternity unless the presumption is affirmatively rebutted by proving "non-access" between spouses, and that the civil courts (Munsiff Court and Sub-Judge) had jurisdiction to decide the legitimacy question raised in the original suit. Because the 2011 judgment on legitimacy had never been challenged and had attained finality between the same parties, the Court held that the principle of res judicata barred the Family Court from reopening the same issue years later under the guise of a maintenance proceeding. The Court found the Family Court's revival of the maintenance petition, and the High Court's endorsement of it, to be a direct contravention of res judicata and an impermissible attempt to relitigate a settled matter. The appeal was allowed, the maintenance proceedings were quashed, and the respondent was held to be the legitimate son of Mr. Raju Kurian.
Lesson Learnt
Once a court has finally decided a question of legitimacy or paternity between two parties and that decision is not appealed, the same issue cannot be reopened later in a different proceeding (such as a maintenance case): the principle of res judicata prevents parties from relitigating settled questions indefinitely.
