Facts: 

On October 17, 2000, the petitioner filed before RTC of Masbate, a petition for the declaration of the absolute nullity of the marriage contracted on December 26, 1949 between his late brother Cresenciano Ablaza and Leonila Honato. Petitioner alleged that the marriage between Cresenciano and Leonila had been celebrated without a marriage license, due to such license being issued only on January 9, 1950, thereby rendering the marriage void ab initio for having been solemnized without a marriage license. He insisted that his being the surviving brother of Cresenciano who had died without any issue entitled him to one-half of the real properties acquired by Cresenciano before his death, thereby making him a real party in interest; and that any person, himself included, could impugn the validity of the marriage between Cresenciano and Leonila at any time, even after the death of Cresenciano, due to the marriage being void ab initio.


Issue: 

May a person bring an action for the declaration of the absolute nullity of the marriage of his deceased brother solemnized under the regime of the old Civil Code?


Held:

A valid marriage is essential in order to create the relation of husband and wife and to give rise to the mutual rights, duties, and liabilities arising out of such relation. The law prescribes the requisites of a valid marriage. Hence, the validity of a marriage is tested according to the law in force at the time the marriage is contracted. As a general rule, the nature of the marriage already celebrated cannot be changed by a subsequent amendment of the governing law.

Considering that the marriage between Cresenciano and Leonila was contracted on December 26, 1949, the applicable law was the old Civil Code, the law in effect at the time of the celebration of the marriage. Hence, the rule on the exclusivity of the parties to the marriage as having the right to initiate the action for declaration of nullity of the marriage under A.M. No. 02-11-10-SC had absolutely no application to the petitioner.

The old and new Civil Codes contain no provision on who can file a petition to declare the nullity of a marriage, and when. However, that the absence of a provision in the old and new Civil Codes cannot be construed as giving a license to just any person to bring an action to declare the absolute nullity of a marriage. The plaintiff must still be the party who stands to be benefited by the suit, or the party entitled to the avails of the suit, for it is basic in procedural law that every action must be prosecuted and defended in the name of the real party in interest. Thus, only the party who can demonstrate a proper interest can file the action. Interest within the meaning of the rule means material interest, or an interest in issue to be affected by the decree or judgment of the case, as distinguished from mere curiosity about the question involved or a mere incidental interest. One having no material interest to protect cannot invoke the jurisdiction of the court as plaintiff in an action. When the plaintiff is not the real party in interest, the case is dismissible on the ground of lack of cause of action.

Here, the petitioner alleged himself to be the late Cresencianos brother and surviving heir. Assuming that the petitioner was as he claimed himself to be, then he has a material interest in the estate of Cresenciano that will be adversely affected by any judgment in the suit. Indeed, a brother like the petitioner, albeit not a compulsory heir under the laws of succession, has the right to succeed to the estate of a deceased brother under the conditions stated in Article 1001 and Article 1003 of the Civil Code.

Pursuant to these provisions, the presence of descendants, ascendants, or illegitimate children of the deceased excludes collateral relatives like the petitioner from succeeding to the deceased's estate. Necessarily, therefore, the right of the petitioner to bring the action hinges upon a prior determination of whether Cresenciano had any descendants, ascendants, or children (legitimate or illegitimate), and of whether the petitioner was the late Cresenciano's surviving heir. 

The petition is returned to the RTC for further proceedings of the case. (Ablaza vs Republic, G.R. No. 158298, August 11, 2010)
