G.R. No. L-1575. May 30, 1961.
RAMONA REYES, plaintiff-appellee, vs. MARIA VILLAFLOR, ET AL., defendants-appellants.

FACTS

This is an action for illegal detainer concerning a parcel of foreshore land. Plaintiff Ramona Reyes had been in possession since 1936 under a revocable permit (RPA Permit No. 5260) from the Bureau of Lands. After liberation, defendant Maria Villaflor entered into a verbal month-to-month lease agreement with Reyes to occupy the land at a monthly rental of P50.00, which she paid until a few months before a fire in April 1957 destroyed her building on the premises.
After the fire, Reyes demanded that Villaflor vacate the land as she intended to construct her own building. Villaflor refused and instead constructed a temporary shed. Reyes then sent a formal demand to vacate on June 24, 1957, which Villaflor ignored. Villaflor defended her refusal by asserting that Reyes’s permit had been cancelled by the Bureau of Lands in 1944 and that she (Villaflor) had filed her own application for the land in 1957. The case was elevated from the justice of the peace court to the Court of First Instance, where it was submitted based on a stipulation of facts.

ISSUE

The core issue is whether the defendants can validly refuse to vacate the leased premises by denying the plaintiff’s title or right to lease the foreshore land at the commencement of their landlord-tenant relationship.

RULING

The Supreme Court affirmed the judgment for the plaintiff, ordering the defendants to vacate. The Court held that in an illegal detainer case, the only issue is the physical or de facto possession of the property, not the de jure title. The elements for such an action are present: a contract of lease, its expiration, and the lessee’s refusal to vacate upon demand. Here, the month-to-month lease had expired, and the defendants refused to leave after a valid demand.
Crucially, the Court applied the conclusive presumption under the Rules of Court that a tenant is prohibited from denying the title of their landlord at the commencement of the landlord-tenant relation. The defendants, having entered into a lease agreement with the plaintiff in 1957, are estopped from later asserting that the plaintiff had no right to lease the land due to the alleged 1944 cancellation of her permit. This legal principle renders the defendants’ claims about the permit’s cancellation and their own pending application with the Bureau of Lands immaterial to the possessory action of illegal detainer. Consequently, the Court found it unnecessary to address the ancillary argument that the dispute should be resolved by the Bureau of Lands.
