G.R. No. 129820 ; November 30, 2006
PNOC-ENERGY DEVELOPMENT CORPORATION (PNOC-EDC), Petitioner, vs. EMILIANO G. VENERACION, JR., Respondent.

FACTS

This case involves conflicting mining claims over Block 159 of the Malangas Coal Reservation. Respondent Emiliano Veneracion applied for a Declaration of Location (DOL) over Block 159 on January 31, 1989, but was informed it could not be registered as the area was part of a coal reservation. He subsequently petitioned for its withdrawal from the reservation and conversion into a mineral reservation. Meanwhile, petitioner PNOC-EDC applied for and was granted a mineral prospecting permit over Block 159 by the Office of Energy Affairs (OEA) on September 4, 1989. PNOC-EDC later submitted an application for a Mineral Production Sharing Agreement (MPSA) covering Block 159, despite being advised to exclude it due to Veneracion’s prior application. On April 13, 1992, Presidential Proclamation No. 890 excluded Block 159 from the coal reservation, opening it for mining applications. Veneracion immediately filed a protest against PNOC-EDC’s MPSA application before the Regional Executive Director (RED).
The RED ruled in favor of Veneracion on April 12, 1993, ordering PNOC-EDC to exclude Block 159 from its MPSA. PNOC-EDC’s motion for reconsideration was denied. PNOC-EDC then appealed to the DENR Secretary but filed its appeal beyond the five-day reglementary period prescribed by Presidential Decree No. 463. The DENR Secretary initially gave due course to PNOC-EDC’s MPSA but, upon reconsideration, reinstated the RED’s orders, declaring them final and executory due to PNOC-EDC’s tardy appeal. The Mines Adjudication Board (MAB) affirmed this, ruling Veneracion had preferential rights.

ISSUE

Whether the MAB correctly ruled that respondent Veneracion has a preferential right over Block 159 and that the orders of the RED had become final due to petitioner’s failure to timely appeal.

RULING

Yes, the Supreme Court affirmed the MAB’s decision. The legal logic rests on two pillars: procedural finality and substantive preferential right. Procedurally, the governing law at the time, P.D. No. 463, mandated a strict five-day period to appeal from the RED’s order. Petitioner received the RED’s order on May 7, 1993, but filed its motion for reconsideration only on May 18, 1993, and its appeal to the Secretary on July 30, 1993, both filed beyond the reglementary period. Consequently, the RED’s order became final and executory, depriving the DENR Secretary of jurisdiction to reverse it. The MAB correctly upheld this procedural lapse.
Substantively, the MAB correctly recognized Veneracion’s preferential right. The established procedure for acquiring mining rights within a reservation required sequential steps: a prospecting permit, an exploration permit, an application for exclusion, a presidential proclamation of exclusion, and finally, a lease application with priority given to the exploration permit holder. The record shows PNOC-EDC failed to secure a crucial exploration permit from the Bureau of Mines for Block 159. In contrast, Veneracion, having initiated the process for exclusion as early as 1989 and having completed all requirements for an MPSA immediately after the land was declared open, validly possessed a prior and preferential claim. Therefore, the MAB’s ruling was in accordance with both procedural rules and substantive mining law.
