Greenhills Mining Company vs. Office of the President

The Court held that mining claims located and registered within a government forest reservation without the requisite prospecting permit from the Bureau of Forest Development are void. Where prior mining claims have been abandoned, the land reverts to the public domain, and any subsequent relocation is subject to existing reservations and permitting requirements under Commonwealth Act No. 137 (the Mining Act).

The Southern Zambales Forest Reserve was established by Proclamation No. 245 in 1956. Mining claims within this area had been originally located and registered in 1933 and 1934 under the Philippine Bill of 1902 but were abandoned due to failure to perform annual assessment work. In 1970-1971, petitioner Greenhills Mining Company relocated these abandoned claims and filed Lode Lease Applications. In 1979, private respondent Green Valley Company applied for and obtained a prospecting permit and subsequent exploration permits from the relevant bureaus for areas within the same reserve, which conflicted with Greenhills' claims. Administrative protests and appeals ensued, culminating in the Office of the President declaring Greenhills' claims invalid and granting Green Valley preferential rights.

Mining claims within the Southern Zambales Forest Reserve were originally located and registered in 1933 and 1934 under the Philippine Bill of 1902. These claims were abandoned due to the original locators' failure to perform annual assessment work. The forest reserve itself was established in 1956. In 1970 and 1971, Greenhills Mining Company relocated these abandoned claims, executed Declarations of Location, registered them, and filed Lode Lease Applications. In 1975, Greenhills applied for and was granted a prospecting permit by the Bureau of Forest Development (BFD), which expired in 1978. In 1979, Green Valley Company applied for and obtained a prospecting permit from the BFD and subsequently exploration permits from the Bureau of Mines and Geo-Sciences (BMGS) for overlapping areas. Upon verification, the BMGS found conflicts with Greenhills' claims. Greenhills protested, leading to administrative orders amending Green Valley's permits. On appeal, the Office of the President ultimately declared Greenhills' claims null and void for lack of a valid prospecting permit and upheld Green Valley's preferential right.

• Petitioner argued that mining claims located under the 1902 Philippine Bill, even if later abandoned, could be validly relocated by another person.
• Petitioner contended that the 1956 forest reservation could not include areas previously covered by valid, pre-existing mining locations, citing McDaniel v. Apacible.
• Petitioner asserted that the BMGS correctly ordered the exclusion of its claims from Green Valley's exploration permit based on prior registered locations.
• Petitioner claimed its relocation of the 1933-1934 claims was valid and that questions on their validity were barred by statute.
• Petitioner also alleged that an "Exploration Agreement" between Green Valley and a foreign entity violated the 1973 Constitution.

• Respondent Green Valley countered that Greenhills' protest was moot because its own prospecting permit had expired and the area was open when Green Valley applied.
• Respondent maintained that the validity of mining claims should be determined by the Bureau of Mines, not the Bureau of Forest Development.
• The Office of the President's position, as adopted by the Court, was that Greenhills' claims were invalid because they were located within a forest reservation without the required prospecting permit from the BFD, as mandated by Section 28(a) of C.A. No. 137.
• Respondent argued that the original 1933-1934 claims were abandoned, returning the land to the public domain, and thus Greenhills could not claim privity with those prior, forfeited locations.

• Procedural Issues: N/A
• Substantive Issues:
  • Whether Greenhills' mining claims, relocated within a forest reserve without a prospecting permit from the BFD, were valid.
  • Whether the prior abandonment of 1933-1934 mining claims affected the status of the land when the forest reserve was established in 1956.
  • Whether Green Valley, having complied with prospecting and exploration permit requirements, had a superior right to the area.

• Procedural: N/A
• Substantive: The Court affirmed the Office of the President. It held that Greenhills' mining claims were null and void because they were located within the Southern Zambales Forest Reserve without the mandatory prospecting permit from the Bureau of Forest Development, as required by Section 28(a) of C.A. No. 137 (now Section 13(a) of P.D. No. 463). The Court found that the original 1933-1934 claims had been abandoned, causing the land to revert to the public domain prior to the reserve's creation. Therefore, Greenhills' relocation was subject to the reservation's restrictions. Green Valley, having fully complied with the permitting process, was correctly granted preferential rights.

• Segregation of Mineral Lands from Public Domain — The Court distinguished prior rulings (e.g., McDaniel v. Apacible) that a valid mining location segregates land from the public domain. It held this doctrine did not apply because the original claims had been abandoned, and the subsequent relocation by Greenhills was itself invalid for non-compliance with permitting laws applicable to forest reserves.
• Deference to Administrative Agencies — The Court reiterated the established doctrine that decisions of administrative agencies (like the Office of the President) are entitled to great weight and respect and will not be disturbed absent fraud, collusion, arbitrariness, or total lack of substantial evidence.

• "The established doctrine that where there is no showing of fraud, collusion, arbitrariness, illegality, imposition or mistake on the part of the Office of the President or a department head... such administrative decisions are entitled to great weight and respect and will not be interfered with by the courts."
• "The petitioner cannot, moreover, claim privity of title with the owners of the prior locations. Such prior locations had been abandoned, or at most, forfeited, and the petitioner's own location cannot be considered a continuation thereof."

• McDaniel v. Apacible (42 Phil. 749) — Cited by petitioner for the principle that a reservation cannot include prior perfected mining locations. The Court distinguished it, finding no valid, existing prior claim at the time the reserve was established due to abandonment.
• Gold Creek Mining Corporation v. Rodriguez (66 Phil. 259) and Salacot Mining Company v. Abadilla (67 Phil. 110) — Also cited by petitioner and similarly distinguished by the Court on the same grounds as McDaniel.
• Lacuesta v. Herrera (G.R. No. 33646, 62 SCRA 115) — Cited to support the principle of judicial deference to administrative decisions.

• Section 28(a), Commonwealth Act No. 137 (now Section 13(a), Presidential Decree No. 463) — The controlling provision requiring a prospecting permit from the BFD for exploration in mineral reservations. The Court relied on this to invalidate Greenhills' claims.
• Section 36, Philippine Bill of 1902 — Cited for the requirement to perform annual assessment work, the failure of which led to the abandonment of the original 1933-1934 claims.
• Proclamation No. 245 (1956) — The executive order establishing the Southern Zambales Forest Reserve, which formed the backdrop for the dispute.
