Mootness Doctrine When Courts Decline TO Rule After Case Resolution

The Supreme Court’s decision in Spouses Rebamonte v. Spouses Lucero (G.R. No. 237812, October 2, 2019) clarifies a critical point in Philippine civil procedure: a party who actively participates in a case for decades cannot suddenly question the court’s jurisdiction after an adverse ruling. The case underscores the doctrine of estoppel by laches, which prevents litigants from raising jurisdictional issues belatedly when they had every opportunity to do so earlier.

The Facts of the Case

The dispute involved two one-hectare portions of Lot No. 1305-A in Sultan Kudarat, originally owned by Marcos Lucero and Tomasa Rebamonte. In 1980, Marcos and Tomasa sold the entire lot to their son, respondent Guillermo Lucero. However, prior to that sale, three unregistered sales allegedly took place in favor of petitioner Lino Rebamonte, Tomasa’s cousin.

Two of these sales were executed by Guillermo’s sisters, Josefina and Agripina, who claimed to have received the portions as advance inheritance. The respondents filed a complaint for recovery of real property, possession, quieting of title, damages, and attorney’s fees before the Regional Trial Court (RTC) in 1990.

The RTC ruled in 2012 that the two deeds of absolute sale executed by the sisters were null and void, as they had no ownership rights or authority to sell. The Court of Appeals affirmed this decision. The petitioners then appealed to the Supreme Court, raising for the first time three new arguments: lack of RTC jurisdiction, defective service of summons, and failure to substitute a deceased party.

The Issue on Jurisdiction

The petitioners argued that the RTC lacked jurisdiction because the assessed value of the property was only P11,120.00, below the P20,000.00 threshold for RTC jurisdiction under Batas Pambansa Blg. 129, as amended by Republic Act No. 7691. Under Section 33(3), the Municipal Trial Court (MTC) has exclusive original jurisdiction over actions involving title to or possession of real property where the assessed value does not exceed P20,000.00.

The Supreme Court agreed that, on the merits, the RTC indeed lacked jurisdiction. However, the Court refused to vacate the RTC’s decision, applying the doctrine of estoppel by laches.

The Doctrine of Estoppel by Laches

While jurisdiction over the subject matter is conferred by law and cannot be waived, the Court has recognized exceptions. In the seminal case of Tijam v. Sibonghanoy (131 Phil. 556 [1968]), the Court barred a party from raising lack of jurisdiction after 15 years of active participation in the proceedings.

The Court in Rebamonte identified four exceptional circumstances from Tijam: (1) a statutory right existed in favor of the claimant; (2) the statutory right was not invoked; (3) an unreasonable length of time lapsed before raising the issue; and (4) the claimant actively participated in the case and sought affirmative relief.

In Rebamonte, the petitioners filed their Answer and Amended Answer, sought affirmative relief through a counterclaim, participated in pre-trial and trial, presented witnesses, cross-examined respondents’ witnesses, and filed motions for reconsideration before both the RTC and the Court of Appeals. They raised the jurisdictional issue only 28 years after the complaint was filed—longer than the delays in Tijam (15 years) and Amoguis v. Ballado (22 years).

The Other Belated Issues

The Court also rejected the petitioners’ arguments on defective service of summons and failure to substitute a deceased party.

On service of summons, the Court cited Rule 14, Section 20 of the Rules of Court: a defendant’s voluntary appearance is equivalent to service of summons. The petitioners’ extensive participation in the proceedings constituted voluntary appearance, barring any claim of defective service.

On substitution, the Court noted that mere failure to substitute a deceased party is not sufficient to nullify a decision. The party alleging nullity must prove an undeniable violation of due process. Since the respondents fully participated and presented evidence throughout the trial, no due process violation existed.

Practical Takeaways

• Raise jurisdictional issues early. A party cannot wait for an adverse decision before questioning a court’s jurisdiction. The longer the delay, the stronger the case for estoppel by laches.
• Active participation waives procedural objections. Filing pleadings, seeking affirmative relief, and participating in trial all constitute voluntary appearance and may bar later objections to service of summons.
• Laches applies to jurisdiction. While jurisdiction is generally conferred by law and cannot be waived, the doctrine of estoppel by laches can bar a party from raising it after an unreasonable delay.
• Failure to substitute a deceased party is not automatically fatal. The key question is whether due process was violated, not mere technical noncompliance with the rules.
• New arguments cannot be raised on appeal. Issues not raised before the trial court are barred by estoppel and cannot be considered for the first time on appeal.
