G.R. No. 148622 - Republic vs. City of Davao

Case Summary (G.R. No. 148622)

Applicable law and constitutional framework

Governing constitutional framework: 1987 Philippine Constitution (applicable as the decision post-dates 1990). Primary statutes and instruments invoked: Presidential Decree No. 1586 (Environmental Impact Statement System, “PD 1586”); Presidential Decree No. 1151 (provisions on Environmental Impact Statements, “PD 1151”); Republic Act No. 7160, Section 15 and 16 (Local Government Code, defining LGUs and their duty to promote a balanced ecology); Proclamation No. 2146 (declaring environmentally critical projects and areas); Administrative Code and Civil Code provisions establishing juridical-person status of the State and its political subdivisions.

Factual background leading to the dispute

On August 11, 2000, the City of Davao applied to EMB Region XI for a Certificate of Non-Coverage (CNC) for the Artica Sports Dome, submitting location map, project description, and certification from the City Planning and Development Office that the site was not in an environmentally critical area. EMB Region XI denied the CNC, concluding the project was within an environmentally critical area and thus subject to the EIA/ECC requirement under PD 1586 (as informed by PD 1151). The City filed a petition for writ of mandamus and preliminary injunction in the Regional Trial Court (Civil Case No. 28,133-2000) to compel issuance of the CNC.

Trial court ruling and rationale

The Regional Trial Court granted the City’s petition, issuing mandamus and permanent injunction and ordering DENR/EMB to issue the CNC. The RTC reasoned that PD 1586, PD 1151, and related implementing directives applied to national government agencies, instrumentalities, and private entities but did not expressly require local government units (LGUs) to comply; hence, under expressio unius est exclusio alterius an LGU was excluded. The RTC also accepted factual evidence (including DENR-CENRO-West and PHIVOLCS data) that the project was not within an environmentally critical area and was not an environmentally critical project.

DENR’s motion for reconsideration and Supreme Court invocation

DENR sought reconsideration in the trial court, which was denied. DENR then petitioned the Supreme Court by way of petition for review on certiorari. After a change in the national administration, the City manifested its agreement that an ECC should be secured for the project, rendering the petition arguably moot; nevertheless the Supreme Court proceeded to resolve the legal issues for guidance.

Supreme Court’s threshold determination on LGUs and PD 1586 coverage

The Supreme Court rejected the RTC’s categorical exclusion of LGUs from PD 1586. Relying on RA 7160’s definition of LGUs as bodies politic and corporate that exercise governmental functions, the Court emphasized that when LGUs exercise governmental powers they operate as agencies of the national government. Given Section 16 of RA 7160 which charges LGUs with ensuring a balanced ecology, and considering the policy goals and “Whereas” clauses of PD 1586 promoting comprehensive and integrated environmental protection, the Court held that LGUs fall within the ambit of PD 1586’s coverage. The Court invoked rules of statutory construction — every part of a statute must be read in context and kept subservient to the enactment’s general intent — to conclude that express exclusion was not warranted.

Statutory language and juridical-person analysis

The Court examined Section 2 of PD 1586 (establishing the EIS system for “all agencies and instrumentalities of the national government, including government-owned or controlled corporations, as well as private corporations, firms and entities”) and Section 4 of PD 1151 (requiring Environmental Impact Statements for “all agencies and instrumentalities of the national government … and private corporations, firms and entities”). It noted that under the Civil Code and Administrative Code, the State and its political subdivisions (LGUs) are juridical persons; therefore the term “person” in Section 4 of PD 1586/PD 1151 encompasses LGUs. The Court concluded LGUs are not excluded from the EIS system and have duties consistent with PD 1586’s objectives.

Court’s treatment of the mootness claim and institutional function

Although the City later manifested that it would secure an ECC — a development that could render the controversy moot and academic — the Supreme Court exercised its “symbolic function to educate the bench and bar” and proceeded to decide the legal issues to guide EIS implementation.

Evidence submitted by the City on non-critical status

The City presented specific evidence to establish that the Artica Sports Dome was not an environmentally critical project and was not located in an environmentally critical area: (1) certification from the City Planning and Development Office that the site was not within an environmentally critical area; (2) DENR-CENRO-West certification indicating the project area was on an 18–30% slope, outside NIPAS coverage and not within a declared watershed; (3) PHIVOLCS certification locating the site well outside identified fault zones and buffer requirements. The RTC found these facts persuasive.

Standard of review: deference to trial court factual findings

The Supreme Court reiterated the principle that factual findings of the trial court, when supported by the record, are binding and will not be disturbed on appeal because the Court is not a trier of facts. The Court listed established exceptions when appellate courts may disregard trial court findings (e.g., findings based on speculation, manifestly mistaken inferences, grave abuse of discretion, misapprehension of facts, conflicts with the record), and concluded none of those exceptions applied here. Therefore the trial court’s factual conclusion that the project and site were not environmentally critical was accepted.

Proclamations and implementation of the EIS system

The Court reviewed the mechanism by which projects/areas are declared environmentally critical: under PD 1586 and its im

Case Syllabus (G.R. No. 148622)

Procedural Posture

Petition for review on certiorari filed with the Supreme Court assailing the May 28, 2001 decision of the Regional Trial Court (RTC) of Davao City, Branch 33, which granted the writ of mandamus and injunction in favor of respondent City of Davao and directed the DENR to issue a Certificate of Non-Coverage (CNC).
Case docketed in the RTC as Civil Case No. 28,133-2000; petition record references (Rollo pp. 9-30; RTC decision pp. 31-43).
Petitioner (Republic of the Philippines, represented by DENR and DENR-Region XI/EMB officials) filed motion for reconsideration in the RTC, which was denied; thereafter petition for certiorari to the Supreme Court ensued.
A supervening change of administration prompted respondent City of Davao to file a manifestation expressing agreement with petitioner that an Environmental Compliance Certificate (ECC) is needed, rendering the petition arguably moot and academic; nonetheless, the Supreme Court addressed the issue for guidance of implementors of the EIS law and to educate the bench and bar.

Antecedent Facts (Application and DENR Action)

On August 11, 2000, respondent City of Davao filed an application for a Certificate of Non-Coverage (CNC) with the Environmental Management Bureau (EMB), Region XI, for its proposed project, the Davao City Artica Sports Dome.
Attached to the CNC application were the required documents: (a) detailed location map of the project site; (b) brief project description; and (c) a certification from the City Planning and Development Office that the project is not located in an environmentally critical area (ECA).
EMB Region XI denied the CNC application on the ground that the proposed project was within an environmentally critical area and ruled that, pursuant to Section 2 of Presidential Decree No. 1586 (Environmental Impact Statement System) in relation to Section 4 of Presidential Decree No. 1151 (Philippine Environment Policy), City of Davao must undergo the Environmental Impact Assessment (EIA) process and secure an Environmental Compliance Certificate (ECC) before construction.

City of Davao’s Claim and Relief Sought in RTC

City of Davao alleged its proposed project was neither an environmentally critical project nor within an environmentally critical area, thus outside the scope of the EIS system.
City of Davao contended that issuance of a CNC was a ministerial duty of DENR/EMB upon submission of required documents; hence it filed a petition for mandamus and injunction before the RTC to compel issuance of the CNC.
The RTC granted relief, issuing the writ of mandamus and making a preliminary injunction (issued December 12, 2000) permanent; the RTC directed DENR to issue the CNC and ordered costs de oficio.

Trial Court Reasoning and Findings

The RTC concluded PD 1586, in relation to PD 1151 and LOI No. 1179 (guidelines for compliance with EIA system), did not require local government units (LGUs) to comply with the EIS law; the mandate applied to agencies and instrumentalities of the national government, including government-owned or controlled corporations, and private corporations, firms and entities.
The RTC applied expressio unius est exclusio alterius to hold that an LGU, not being an agency or instrumentality of the National Government, was excluded from coverage.
On facts, the RTC relied on certifications and data (from DENR-CENRO-West and PHIVOLCS) and found the project site was not within an environmentally critical area and that the project was not environmentally critical.
Consequently, the RTC held DENR had a ministerial duty to approve the CNC once requirements were satisfied and could be compelled by writ of mandamus if it refused.

Respondent’s Post-Petition Manifestation and Mootness

Following a change in administration, respondent City of Davao filed a manifestation agreeing with petitioner that an ECC is required for the proposed project, effectively rendering the petition moot and academic.
Despite the manifestation and mootness, the Supreme Court proceeded to address the legal issue for guidance and its symbolic function to educate the bench and bar.
