G.R. No. L-17738 - Dinoso vs. Court of Appeals

Appellant Lupo L. Dinoso and respondent Antonio D. Fontillas are central to the dispute.
Modesta Feria, the vendor, sold four parcels of land; three located in San Narciso, Zambales, and one in sitio Cawayan Kiling, Cabangan, Zambales (the lot in question).
The vendor was granted a right to repurchase the properties on or before December 1, 1946.

On December 18, 1944, respondent Fontillas bought the four parcels, thereby initiating the sequence of title consolidations.
Fontillas consolidated his ownership by registering the deed of sale with the right to repurchase in accordance with Act 3344 on January 10, 1946.
However, Fontillas did not take possession of the disputed property because Dinoso refused to surrender his hold on it.

On April 6, 1940, Modesta Feria executed a pacto de retro sale in favor of appellant Dinoso, as evidenced by Exhibit 1.
This document was later registered on May 25, 1948.
After the execution of the pacto de retro sale, Dinoso took possession of the property in question and remained in possession when the present action commenced on September 4, 1952.

A comparison between the boundaries of the parcel sold under the pacto de retro sale to Dinoso and that sold to Fontillas revealed distinct differences, establishing that they were different properties.
While appellant did not contest the non-identity finding of the parcels, his primary arguments were directed towards his claim of title by adverse possession.

In his answer, Dinoso specifically denied Fontillas’ claim of ownership, asserting instead that he had acquired title in fee simple through the consolidation of the title under the pacto de retro sale.
Dinoso relied on the fact that the vendor’s right to repurchase was not exercised, making him the absolute owner.
He did not plead that, regardless of the transaction, he had held the property adversely for the requisite period (more than ten years under Act 190, sec. 41).

The Court of Appeals noted that Dinoso’s failure to specifically plead adverse possession—as required under the new Rules of Court (Rule 9, sections 6, 7, and 8)—resulted in a shift in defense theory that was unfair to the respondent.
The appellate court emphasized the need for specific denials to prevent any form of surprise, ensuring that all the true facts underpinning the defense are properly disclosed.

Whether the land sold by Modesta Feria to Fontillas is the same parcel as the one sold to Dinoso.
The conclusive evidence comparing the boundaries supports their difference.

Whether, assuming the properties were indeed different, Dinoso acquired title by prescription (adverse possession) to the land conveyed to Fontillas.
Whether Dinoso's possession met the legal requirements of being hostile, open, and continuous after the expiration of the vendor's right of redemption.

Whether Dinoso's failure to specifically plead adverse possession—as opposed to maintaining the defense based solely on a sale with a right of repurchase—precluded the application of the adverse possession doctrine.
Whether the change in defense theory to include adverse possession, not properly interposed in his initial pleadings, should render his claim impermissible.
