Metropolitan Manila Development Authority et al. v. Concerned Residents of Manila Bay, G.R. Nos. 171947-48, December 18, 2008, the Supreme Court En Banc, Velasco Jr., J., writing for the Court.

On January 29, 1999, Concerned Residents of Manila Bay filed a complaint in the Regional Trial Court (RTC), Branch 20, Imus, Cavite (Civil Case No. 1851-99), naming several national government agencies — including MMDA, DENR, DepEd, DOH, DA, DPWH, DBM, PPA, MWSS, LWUA, the Philippine Coast Guard, and the PNP Maritime Group — as defendants and seeking an order to clean up, rehabilitate, and restore Manila Bay to Class B (SB) water quality standards under PD 1152 and related laws. The complaint alleged massive, ongoing pollution (including fecal coliform levels greatly exceeding prescribed limits) that impaired public health, fisheries, and recreational uses, and invoked constitutional and statutory rights and duties (PD 1152, PD 979, PD 1067, RA 9003, RA 9275, RA 8550, RA 6969, among others).

The MWSS, LWUA, and PPA appealed to the Court of Appeals (CA) (consolidated as CA-G.R. CV No. 76528). Several other petitioners filed a petition for review under Rule 45 directly with the Supreme Court; the Court, by Resolution dated December 9, 2002, transmitted that petition to the CA for consolidation with the CA appeals (docketed as CA-G.R. SP No. 74944). By Decision dated September 28, 2005, the CA denied the appeals and affirmed the RTC in toto, holding that the trial court had not required agencies to act beyond their statutory functions.
