G.R. No. L-16391. April 30, 1964.
HECTOR MORENO, petitioner, vs. MACARIO TANGONAN, ET AL., respondents.

FACTS

Petitioner Hector Moreno is the landowner, and respondents Macario Tangonan and Eugenio Tagatac are his share tenants on a hacienda in Nueva Ecija. They operated under written tenancy contracts for the 1956-1957 agricultural year, stipulating a 55-45 sharing ratio in favor of the tenants, with expenses for final harrowing and transplanting borne equally. The contracts were for a period from June 1, 1956, to May 31, 1957, and were renewable yearly unless notice was given before expiration. The harvest for 1956-1957 was divided accordingly.
At the start of the next agricultural year, 1957-1958, the respondents refused to renew their contracts. They proceeded with cultivation, performing final harrowing and transplanting without asking for the landowner’s share of the expenses, despite the overseer’s virtual offer to contribute. In September 1957, after these operations were completed, the respondents formally demanded a change in the sharing ratio to 70-30 in their favor, arguing they had borne all cultivation costs. The petitioner refused this demand.

ISSUE

Whether the respondents’ actions constituted a substantial violation of their tenancy contracts, justifying their ejectment under Section 50(b) of Republic Act No. 1199.

RULING

The Supreme Court affirmed the decision of the Court of Agrarian Relations (CAR), dismissing the petition for ejectment and ordering the maintenance of the respondents as tenants. The Court held that the respondents’ actions did not amount to a substantial violation warranting dispossession.
The legal logic centers on the interpretation of the tenants’ conduct and the requirements for ejectment under agrarian law. The Court recognized the respondents’ right to seek a modification of the sharing ratio upon the expiration of the initial contract period on May 31, 1957. While the CAR found that their formal demand in September 1957 was belated and thus ineffective to change the ratio for that year, it concurrently found they had acted in good faith. The Supreme Court agreed, emphasizing that the respondents’ conduct at the season’s start—specifically, their refusal to renew contracts and their undertaking of cultivation expenses alone—constituted sufficient notice to the landowner of their intent to modify the terms. This overt action served as a clear, albeit informal, manifestation of their desire for a new arrangement.
Consequently, the delay in making a formal demand was a procedural mistake but not a substantive breach of contractual obligations severe enough to constitute grounds for ejectment under Section 50(b) of RA 1199. Ejectment requires a serious violation, and the respondents’ good-faith attempt to exercise their rights, coupled with the timely constructive notice through their actions, negated the presence of such a violation. The paramount policy of maintaining tenants in peaceful possession, absent a clear legal cause for displacement, governed the decision.
