G.R. No. L-11621; May 31, 1962
FELICISIMO RONQUILLO, deceased, substituted by ANTONIA DE GUZMAN VDA. DE RONQUILLO, ET AL., plaintiffs-appellants, vs. FRANCISCO MARASIGAN, defendant-appellant.

FACTS

The case originated from a verbal ten-year lease of nipa-land from December 1, 1941, between Felicisimo Ronquillo and Francisco Marasigan. Marasigan dispossessed Ronquillo in September 1942, leading to Civil Case No. 80. The final judgment, as modified by the Court of Appeals, ordered Marasigan to deliver the land to Ronquillo and execute a deed of lease for ten years from December 1, 1941, but excluding the five-year period from September 1, 1942, to August 31, 1947, which Ronquillo did not enjoy. For execution, Ronquillo deposited the full ten-year rental. Marasigan withdrew this entire amount after Ronquillo was placed in possession. However, a dispute arose over the lease term in the deed. The trial court, in an order dated January 18, 1950, interpreted the judgment to mean Ronquillo was entitled to a lease term starting from his repossession in 1950, lasting only for the unexpired balance of the original term after deducting the lost five years and the initial nine months. Ronquillo did not appeal this 1950 order.

ISSUE

The core issue is whether a subsequent action (Civil Case No. 997) filed by Ronquillo to enforce a full ten-year lease from the date of repossession, based on Marasigan’s acceptance of the full ten-year rental, is barred by res judicata due to the finality of the 1950 execution order.

RULING

The Supreme Court reversed the dismissal of Civil Case No. 997, holding that res judicata does not bar the new action. The legal logic is twofold. First, Marasigan’s act of withdrawing the full ten-year rental deposit constituted an acquiescence to a new ten-year term from the date of repossession, creating new rights separate from the original judgment. This act gave rise to an estoppel, preventing Marasigan from claiming a shorter term, as one cannot unjustly enrich oneself by accepting payment for a period not granted. Second, the Court emphasized that technical rules like res judicata must not be applied to sacrifice substantial justice. The Court has the inherent power to suspend its own rules to prevent a denial of justice. The finality of the 1950 order does not preclude modification when its execution becomes unjust, as here, where Marasigan retained full payment for a lease term he was contesting. The new suit was essentially a continuation to implement the original judgment’s core mandate in light of these new equitable circumstances.
