G.R. No. 143188 . February 14, 2007.
FLORENTINO PINEDA, Petitioner, vs. HEIRS OF ELISEO GUEVARA, represented by ERNESTO E. GUEVARA and ISAGANI S. GUEVARA, namely: ELISEO GUEVARA, JR., ZENAIDA G. SAPALICIO, DANTE G. GUEVARA, DANILO C. GUEVARA, and ISAGANI S. GUEVARA, Respondents.

FACTS

The respondents, heirs of Eliseo Guevara, filed an action for the nullification of certificates of title over a parcel of land in Marikina, claiming co-ownership derived from Original Certificate of Title (OCT) No. 386 issued in 1910. They alleged that the defendants, including petitioner Florentino Pineda, derived their titles from a fake OCT No. 629 issued later in 1912. The defendants, in their respective answers, raised affirmative defenses including lack of cause of action, prescription, laches, and estoppel, with Pineda asserting he was a buyer in good faith in possession since 1970.
The Regional Trial Court (RTC), after treating the case as if a motion to dismiss had been filed and conducting a hearing on the pleadings and memoranda, dismissed the complaint solely on the ground of laches. The Guevara heirs appealed to the Court of Appeals, arguing a denial of due process. The appellate court reversed the RTC, ruling that laches is not a ground for a motion to dismiss under Rule 16 of the Rules of Court and that the other affirmative defenses did not warrant dismissal at that stage.

ISSUE

The core issues were: (1) whether the appeal to the Court of Appeals was proper despite raising questions of law; and (2) whether the RTC correctly dismissed the action on the ground of laches.

RULING

The Supreme Court denied the petition and affirmed the Court of Appeals. On the first issue, the appeal was properly taken to the Court of Appeals as it involved a review of the RTC’s factual determination in applying laches, which is a question of fact or at least a mixed question of law and fact, falling within the appellate court’s jurisdiction.
On the substantive issue, the Court upheld that laches is not one of the grounds for a motion to dismiss enumerated under Rule 16, Section 1. While it can be invoked as an affirmative defense in an answer, it must be proven during a full trial on the merits. The RTC’s dismissal based solely on the pleadings and memoranda, without a trial, was premature. Laches is evidentiary in nature, requiring an examination of the circumstances of delay and any resulting prejudice, which cannot be conclusively determined from the pleadings alone. The RTC’s order was therefore a dismissal under Rule 16, not a summary judgment under Rule 35, as there was no proper motion for summary judgment supported by affidavits, depositions, or admissions. Consequently, the case was correctly remanded to the RTC for trial.
