Res Judicata Bars Second Nullity Suit on Different Ground

In a significant ruling on the doctrine of res judicata, the Supreme Court held that a party cannot file a second petition to declare a marriage void on a different ground after the first petition has been finally denied. The case of Mallion v. Alcantara (G.R. No. 141528, October 31, 2006) clarifies that a marriage's validity is a single cause of action, and litigants must present all available grounds in one proceeding.

The Facts of the Case

Oscar Mallion filed a petition in 1995 seeking to nullify his marriage to Editha Alcantara on the ground of psychological incapacity under Article 36 of the Family Code. The Regional Trial Court of San Pablo City denied the petition in 1997 for failure to adduce preponderant evidence. The Court of Appeals later dismissed his appeal for non-payment of docket fees, and the decision became final.

Two years later, Mallion filed a second petition for declaration of nullity of the same marriage, this time alleging that the marriage was void because it was celebrated without a valid marriage license. The respondent moved to dismiss on the grounds of res judicata and forum shopping, and the trial court granted the dismissal.

The Issue Presented

The question before the Supreme Court was one of first impression: Does a previous final judgment denying a petition for declaration of nullity on the ground of psychological incapacity bar a subsequent petition for declaration of nullity on the ground of lack of marriage license?

The Ruling: One Cause of Action, Many Grounds

The Supreme Court denied Mallion's petition and upheld the dismissal. The Court ruled that although the two petitions cited different statutory grounds, they involved the same cause of action: the declaration of nullity of the same marriage.

Under Rule 2, Section 2 of the Rules of Court, a cause of action is the act or omission by which a party violates the right of another. In both petitions, the cause was identical—the nullification of the marriage. The grounds cited were merely different legal theories supporting the same claim.

The Court applied the test for identity of causes of action: whether the same evidence would sustain both actions. While the evidence for psychological incapacity differs from that for lack of a marriage license, the Court emphasized that a party cannot divide grounds for recovery. A plaintiff must set forth every ground for relief existing when the suit began, and cannot litigate a case piecemeal.

The Doctrine of Res Judicata Applied

The Court cited Section 47(b) of Rule 39 of the Rules of Court, which provides that a final judgment is conclusive between the parties not only as to matters directly adjudged but also as to any other matter that could have been raised in relation thereto.

Significantly, the Court noted that in the first case, Mallion impliedly conceded that the marriage had been solemnized in accordance with law. By failing to raise the absence of a marriage license in the first proceeding, he was deemed to have waived any defect in the marriage celebration.

The Court further quoted Perez v. Court of Appeals: "A party cannot preserve the right to bring a second action after the loss of the first merely by having circumscribed and limited theories of recovery opened by the pleadings in the first."

Practical Takeaways

• One shot at nullity: A petition for declaration of nullity of marriage must raise all available grounds at once. A final adverse judgment bars a second attempt on a different ground.
• Res judicata is broad: Under Rule 39, Section 47(b), a final judgment bars not only what was decided but also matters that could have been raised in the first case.
• Forum shopping consequences: Filing successive suits on the same marriage can result in dismissal for forum shopping and multiplicity of suits.
• Admissions bind parties: Conceding the validity of a marriage celebration in one case prevents later claiming defects in that celebration.
• Plan the case strategy carefully: Before filing a nullity petition, a thorough factual investigation should identify all possible grounds, as they cannot be raised later.
