Failure to challenge a decree for restitution of conjugal rights operates as res judicata against a divorce appeal.

The Appellant (husband) and Respondent (wife) married in 2015. After the birth of a child in 2016, the wife left the matrimonial home.

The husband initially sought restitution of conjugal rights but withdrew it to file for divorce (HMOP No. 81 of 2023) on grounds of cruelty and desertion.

The wife filed a separate petition for restitution of conjugal rights (HMOP No. 28 of 2023).

Both petitions were tried together by the Subordinate Court, Ambattur. Via a common judgment dated 31.08.2023, the trial court dismissed the husband's divorce petition and allowed the wife’s petition for restitution.

The husband appealed only the dismissal of the divorce petition before the District Court and subsequently the High Court, leaving the decree for restitution of conjugal rights unchallenged.

1. Whether the CMSA is maintainable in the absence of a challenge to the decree passed for restitution of conjugal rights when an appeal is filed only against the dismissal of the divorce petition?

2. Whether the Respondent's police complaints regarding child kidnapping and other allegations constitute mental cruelty?

3. Whether living separately since 2016 constitutes desertion?

4. Whether the Respondent’s insistence on a separate matrimonial home away from the husband's parents amounts to cruelty?

The court applied the doctrine of res judicata as embodied in Section 11 of the Code of Civil Procedure (CPC), 1908, which prevents the re-litigation of issues that have reached finality between the same parties.

The Court relied on the precedent set by the Madras High Court Division Bench in Jeyanthi v. Saravanan (CMA No. 2853 of 2018), which established that where two proceedings between the same parties are tried together and a common order is passed, the failure to challenge one of the resulting decrees is fatal to the appeal of the other.

The Court focused primarily on the additional substantial question regarding maintainability. It observed that the trial court’s common judgment simultaneously dismissed the divorce petition and granted restitution of conjugal rights.

By failing to file an independent appeal against the restitution decree, the husband allowed that decree to attain finality.

The Court rejected the Appellant's argument that a finding of perversity in the divorce dismissal would automatically nullify the restitution decree.

The Court reasoned that since the restitution decree (which mandates cohabitation) and a divorce decree (which dissolves the marriage) are mutually exclusive, the unchallenged restitution decree operates as res judicata, legally barring the husband from pursuing the dissolution of marriage.

Consequently, the Court declined to adjudicate on the merits of cruelty or desertion as they became "of no consequence". The Civil Miscellaneous Second Appeal was dismissed as not maintainable.
