G.R. Nos. 120865-71 December 7, 1995
Laguna Lake Development Authority, petitioner, vs. Court of Appeals; Hon. Judge Herculano Tech, Presiding Judge, Branch 70, Regional Trial Court of Binangonan Rizal; Fleet Development, Inc. and Carlito Arroyo; The Municipality of Binangonan and/or Mayor Isidro B. Pacis, respondents. (Consolidated with six other petitions involving similar parties and issues.)

FACTS

The Laguna Lake Development Authority (LLDA), a government agency created under Republic Act No. 4850 and strengthened by Presidential Decree No. 813, is tasked with the comprehensive development and environmental management of the Laguna Lake region. The LLDA initiated actions to dismantle illegal fishpens and fish enclosures operated by various private corporations in Laguna de Bay, asserting its exclusive jurisdiction to issue permits for such activities under its charter. The affected corporations, however, had secured permits or were operating with the consent of the respective municipal governments where the structures were located.
The private corporations and the involved municipalities filed petitions for prohibition and/or declaratory relief with various Regional Trial Courts (RTCs) to restrain the LLDA’s actions. These RTCs issued writs of preliminary injunction against the LLDA, upholding the authority of the local government units under the Local Government Code of 1991 ( Republic Act No. 7160 ) to issue fishing permits within their municipal waters. The Court of Appeals subsequently affirmed these RTC decisions, prompting the LLDA to elevate the case to the Supreme Court.

ISSUE

The core issue is whether the LLDA, under its charter, has the exclusive authority to issue permits for fishpen operations and other activities in Laguna de Bay, to the exclusion of the powers granted to municipalities over municipal waters under the Local Government Code.

RULING

The Supreme Court ruled in favor of the LLDA, reversing the decisions of the Court of Appeals and the RTCs. The Court held that the LLDA possesses exclusive jurisdiction to issue permits for activities in Laguna de Bay. The legal logic rests on the principle of statutory construction that a special law prevails over a general law. The LLDA’s charter, particularly P.D. No. 813, is a special law that specifically grants the Authority exclusive jurisdiction over the lake for purposes of environmental regulation and sustainable development.
The Local Government Code, while granting municipalities control over municipal waters, is a general law. The Court emphasized that Laguna de Bay is not a municipal body of water but a national resource spanning multiple provinces, requiring centralized management to address complex ecological concerns like pollution and flood control. To allow individual municipalities to issue permits without regard to the lake’s overall carrying capacity would frustrate the LLDA’s mandate for integrated resource management. Consequently, the fishpens and structures erected without an LLDA permit were declared illegal and subject to demolition. The Court clarified, however, that municipalities are not precluded from imposing local fees for revenue purposes on operations already permitted by the LLDA, harmonizing the special and general laws.
