Case Digest (G.R. No. 141801)

Facts:

  • Establishment and Operation of the San Mateo Landfill
    • On November 17, 1988, DENR, DPWH, and MMC entered into a MOA authorizing the use of 18 hectares in Barangay Pintong Bocaue, San Mateo for a sanitary landfill.
    • The dumpsite began operations on February 19, 1990, accepting solid waste from Quezon City, Marikina, San Juan, Mandaluyong, Pateros, Pasig, Taguig, and other areas.
  • Early Objections and Environmental Reports
    • February 1989: The Sangguniang Bayan of San Mateo passed a resolution banning dumpsites, sending letters of objection to MMC, DPWH, DENR, and Malacañang.
    • 1989–1990 DENR/CENRO reports documented:
      • Illegal dumping inside the Marikina Watershed Reservation in violation of PD 705.
      • Adverse impacts on 1,192 families, water sources, soil erosion, slumping, and ecological imbalance.
    • March 9, 1990: LLDA objected to in-watershed dumping due to pollution risks to Laguna Lake and its water supply.
  • Regulatory Actions and Proclamation No. 635
    • February 19, 1990: DENR’s Environmental Management Bureau issued an Environmental Compliance Certificate (ECC) for a 2.5-ha dumpsite; suspended the ECC on July 31, 1990, citing slumping and erosion.
    • November 16, 1993: DENR Secretary Alcala recommended dismantling landfill facilities and relocating operations outside the watershed.
    • August 28, 1995: President Ramos issued Proclamation No. 635, excluding approximately 1,060,529 sqm of watershed land for sanitary landfill under MMDA administration.
    • September 6, 1995: DENR Protected Areas and Wildlife Bureau reiterated that a dumpsite is incompatible with a watershed reservation.
  • Judicial and Administrative Proceedings
    • July 22, 1996: Petitioners filed a petition for certiorari, prohibition, and mandamus in the Court of Appeals, seeking to invalidate Proclamation 635 and related actions; CA denied relief on June 13, 1997.
    • 1998–2001: Continued motions for injunctive relief, local protests, MOAs, and a presidential memorandum (July 19, 1999) set landfill closure by December 31, 2000.
    • January 11, 2001: President Estrada directed reopening due to garbage crisis; Supreme Court issued a TRO on January 24, 2001.
    • January 26, 2001: Republic Act No. 9003 (Ecological Solid Waste Management Act) was signed into law, mandating closure of dumpsites in watershed areas.

Issues:

  • Whether Proclamation No. 635 was invalid because based on a forged DENR recommendation.
  • Whether the landfill’s operation was unlawful due to a spurious ECC.
  • Whether the withdrawal or modification of a protected watershed area may be done only by an Act of Congress (RA 7586).
  • Whether the Court of Appeals erred in disregarding unanimous adverse findings and recommendations of government agencies.
  • Whether Proclamation 635’s “buffer zone” argument erroneously placed the dumpsite outside the watershed boundaries.
  • Whether the CA usurped Congress’s function by justifying continued landfill operations on policy grounds.
