G.R. No. 149927 - Republic vs. Rosemoor Mining and Development Corporation

In 1947, the late Eusebio Pigao, together with his family, settled on a 240-square-meter lot located at 92 (now 102) K-5th Street, Kamuning, Quezon City.
The subject lot was originally government property owned by the People’s Homesite and Housing Corporation (PHHC) under Transfer Certificate of Title (TCT) No. 27287.
Eusebio applied for the purchase of the lot and executed a contract to sell with PHHC for a consideration of P1,022.19.

In 1959, while the title was still in the name of PHHC, Eusebio executed a deed of assignment transferring his right over one-half (the front half portion) of the property to respondent Samuel Rabanillo for P1,000.
Respondent occupied the front half portion, established a residential building thereon, and paid the amortizations for that portion.
Subsequently, in 1970, Eusebio executed a deed of mortgage over the same portion in favor of respondent.

After full payment of the amortizations in 1973, PHHC issued a final deed of sale over the entire lot in favor of Eusebio, and TCT No. 197941 was subsequently issued.
In 1978, respondent executed an affidavit of adverse claim over the front half portion, and this annotation was made on TCT No. 197941.
Eusebio died on June 17, 1979, leaving his children as his heirs (the petitioners).

In 1988, after the Office of the Register of Deeds of Quezon City suffered a fire which destroyed the original title, petitioner Estrella Pigao applied for reconstitution.
In 1990, TCT No. RT-11374 was issued in the name of Eusebio, but this reconstituted title did not carry the adverse claim annotation of respondent.
In 1992, the petitioners executed an extrajudicial settlement of Eusebio’s estate, leading to the issuance of TCT No. 56210 in their names for the entire lot.

On January 29, 1996, petitioners filed Civil Case No. Q-96-26270 in the RTC of Quezon City seeking to quiet title over the entire lot and recover possession of the front half portion.
The RTC ruled in favor of the petitioners, declaring the deed of assignment null and void, and providing remedies against respondent including either requiring respondent to purchase the lot or be reimbursed for the value of his improvements.
The Court of Appeals, in a decision dated October 29, 2001 (CA-G.R. CV No. 60069), reversed the RTC decision in favor of respondent.
Petitioners subsequently elevated the matter to the Supreme Court through a petition for review challenging the CA decision.

Petitioners attempted to introduce a conditional contract to sell (from a transaction involving Armando Bernabe and PHHC) as evidence to prove that there was a prohibition on the sale or assignment of rights without PHHC’s written consent.
The document was not part of the record during trial or appeal, and respondent objected to its admission.
The Court criticized the attempt to take judicial notice of evidence that was neither part of the trial record nor within the ambit of matters mandatorily noteable by law.

Whether the deed of assignment executed by Eusebio in 1959, which transferred his right over the front half portion of the lot to respondent, is valid.
Whether the transaction was affected by the supposed prohibition under Section 118 of Commonwealth Act No. 141 (CA 141) regarding the alienation of rights during the restricted period applicable to public lands.

Whether the transactions and subsequent developments—specifically respondent’s payment of amortizations, occupation, and establishment on the lot—created an implied trust relationship between Eusebio (or his heirs) as trustee and respondent as beneficiary.
Whether Article 1448 of the Civil Code, which is often invoked to recognize a purchase money resulting trust, is applicable in the present circumstances given the policy considerations involved.

Whether the petitioners could properly invoke judicial notice of a conditional contract to sell (pertaining to another lot) to sustain the prohibition claim without having submitted it during trial.
The implications of formal evidence submission on the court’s ability to consider such documents in light of due process.
