G.R. No. 239983 - Republic vs. Spouses Johnny and Chona Yu

The Republic of the Philippines, represented by Major General Dionisio R. Santiago, Commanding General of Armed Forces of the Philippines Visayas Command (Petitioner), filed a Complaint against Spouses Johnny and Chona Yu (Respondents).
Petitioner sought to enjoin Spouses Yu from constructing a residential house on a 252-square meter portion of Lot No. 933 in Lahug, Cebu City.
Petitioner also sought cancellation of Transfer Certificate of Title (TCT) No. 150040 issued in the name of Spouses Yu and issuance of a new title in the Republic’s name.

Petitioner claimed ownership over Lot 933, consisting of 37,126 square meters, originally registered under Francisco Racaza, Pantaleon Cabrera, and Josefina R. Martinez.
Said lot allegedly formed part of Camp Lapu-Lapu military reservation and had a value exceeding PHP 100 million.
In 1938, the Commonwealth of the Philippines initiated expropriation proceedings for various parcels of land including Lot 933 (Civil Case No. 781 before Court of First Instance - CFI).
On May 14, 1940, the CFI rendered a decision condemning the parcels in favor of the Commonwealth, which became final and executory with entry of judgment on April 5, 1948.

Post-decision, original registered owners sold Lot 933, leading to issuance of new certificates, including TCT 150040 in Spouses Yu’s name for a 252-sqm portion.
Petitioner asserted TCT 150040 is null and void since ownership vested in government via expropriation.
Spouses Yu claimed valid purchase and peaceful possession, paying property taxes, and securing clearances prior to construction.
They alleged threats and confiscation of construction tools by AFP personnel after construction commenced.

RTC decided in favor of Petitioner, declaring Spouses Yu had no right over Lot 933, and ordering cancellation of their title and reissuance in Republic’s name.
The RTC held the expropriation decision was binding, prepayment of just compensation was made, and Spouses Yu were not purchasers in good faith.
Spouses Yu’s motion for reconsideration was denied.
The Court of Appeals (CA) reversed the RTC decision, holding no proof of full just compensation payment was presented by Petitioner, rendering expropriation incomplete.
The CA ruled that Spouses Yu’s ownership was valid due to failure of full compensation and recognized them as innocent purchasers.
Petitioner’s motion for reconsideration was denied by the CA.

Petitioner argued that the payment of PHP 9,500 deposit in 1938 complied with just compensation.
Petitioner maintained the CFI decision was final and binding on all, including Spouses Yu.
Spouses Yu argued prior Supreme Court rulings and RA No. 9443 confirmed validity of their title and the Banilad Friar Lands Estate titles.

Whether the Court of Appeals erred in reversing the RTC decision and dismissing the Republic's complaint seeking injunction and cancellation of Spouses Yu's title over the subject portion of Lot 933.

Whether the government complied with the constitutional and legal requirement of full payment of just compensation to the original owners of Lot 933 to complete the expropriation.

Whether the Spouses Yu, as holders of TCT 150040, are protected as owners given the circumstances and legal principles on expropriation and registration.
