GR 165355; (September, 2012) (Digest)
G.R. No. 165355 ; September 26, 2012
Tomas T. Teodoro, Francisco J. Teodoro (substituted upon his death by Tomas T. Teodoro), Salvador Ilano and Teodoro Exploration and Mineral Development Corporation, Petitioners, vs. Continental Cement Corporation, Respondent.
FACTS
The dispute involves conflicting claims over mineral-rich land in Norzagaray, Bulacan. Respondent Continental Cement Corporation (CCC) derived its rights from mining claims registered in 1959 and subsequent Mining Lease Contracts (MLCs). Petitioners, the Teodoros, are registered landowners who later applied for quarry permits on their titled property. The Department of Environment and Natural Resources (DENR) denied the Teodoros’ applications due to conflict with CCC’s claims. A separate, protracted administrative case ensued regarding the validity and renewal of CCC’s mining rights, culminating in a 1998 Court of Appeals decision which declared CCC’s MLCs as subsisting and upheld its right to extract minerals within the claim area, a decision which became final.
Subsequently, in 1992, CCC filed a complaint for injunction with the Regional Trial Court (RTC) after the petitioners, through their caretaker, prevented CCC’s employees from entering the area to conduct a survey. The petitioners argued ownership of the land and their status as legitimate quarry permit applicants. The RTC ruled in favor of CCC, issuing a permanent injunction and awarding damages. The Court of Appeals affirmed this decision.
ISSUE
The core issue is whether the petitioners are legally justified in preventing CCC’s entry and access to the mining claim area, thereby warranting the grant of the injunction in favor of CCC.
RULING
The Supreme Court denied the petition and affirmed the lower courts’ decisions. The legal logic rests on the principle of res judicata and the conclusive determination of CCC’s superior mining rights. The final and executory 1998 Court of Appeals decision in the related administrative case (CA-G.R. SP No. 45396) conclusively established that CCC’s mining lease contracts were valid and subsisting and that it had the right to extract limestone within its mining claim area, which includes the petitioners’ land. This prior judgment constitutes res judicata on the matter of CCC’s legal right to access and utilize the area for mining purposes.
Consequently, the petitioners’ claim of ownership, while recognized, cannot override the specifically established mining rights granted to CCC under the MLCs. Mineral resources are owned by the State, and the grant of a mining lease confers upon the holder the right to explore and extract minerals, which prevails over the surface owner’s rights. The injunction was properly issued to protect CCC’s legally adjudicated right from being violated by the petitioners’ acts of obstruction. The petitioners’ defense that the mining claims were outside their property was correctly rejected by the RTC, as it constituted a waiver for failure to plead it in their answer and was contrary to their prior positions in administrative proceedings.
