G.R. No. L-43882 and G.R. No. L-45321. April 30, 1979.
Angelica Viajar and Celso Viajar, plaintiffs-petitioners/appellants, vs. Hon. Numeriano G. Estenzo, Presiding Judge, Court of First Instance of Iloilo, Branch III, Ricardo Ladrido and Rosendo Te, defendants-respondents/appellees.

FACTS

The petitioners, Angelica and Celso Viajar, filed a complaint for recovery of possession against respondent Ricardo Ladrido. They alleged they are the registered owners of Lot No. 7340. They claimed that due to a natural change in the course of the Suage River, the northeastern portion of their lot was occupied by the new riverbed. Consequently, they asserted ownership over the abandoned riverbed under Article 461 of the Civil Code. They further alleged that Ladrido was in possession of the remaining southwestern portion of their lot (Parcel 2) and the old riverbed.
In his Answer, Ladrido claimed ownership of the adjacent Lot No. 7511, bounded by the Suage River. He asserted that the land in dispute (Parcel 2 and the old riverbed) was not part of the petitioners’ lot but was accretion to his own property, formed by gradual soil deposits from the river since the 1920s, which he possessed, invoking Article 457 on accretion. The petitioners filed a Reply, insisting the change was sudden, falling under Article 461, and that the old riverbed still separated the two lots, negating accretion.

ISSUE

Whether the trial court correctly rendered a summary judgment in favor of the respondent, dismissing the petitioners’ complaint.

RULING

No. The Supreme Court set aside the summary judgment and remanded the case for trial. The core legal principle is that a summary judgment is only proper when, based on the pleadings, affidavits, and documents, there is no genuine issue as to any material fact. Here, a genuine and substantial factual issue existed. The central dispute—whether the land possessed by Ladrido is an accretion to his lot (Article 457) or whether the petitioners own it due to a sudden change in the river’s course entitling them to the abandoned bed (Article 461)—is a quintessential question of fact requiring a full trial.
The parties presented diametrically opposed factual theories supported by their pleadings. The petitioners’ allegation of a sudden change, which would grant them rights to the old bed, was directly contested by Ladrido’s claim of gradual accretion, which would vest ownership in him. The trial court’s reliance on a purported “admission” from the petitioners’ complaint was erroneous, as the complaint did not clearly admit a gradual process but described a natural change. Summary judgment cannot be based on dubious constructions of pleadings. The Court emphasized that where facts are disputed, a summary judgment cannot replace a trial. The movant for summary judgment bears the burden of proving the absence of any genuine issue, and any doubt must be resolved against the movant. The trial court failed to observe the required vigilance, issuing the judgment without the supporting affidavits or a proper hearing on the motion, thereby depriving the petitioners of their right to a plenary trial on the merits.
