Navarro vs. Ermita
Case
G.R. No. 180050
Decision Date
May 12, 2010
Dinagat Islands' creation via RA 9355 ruled unconstitutional for failing population and land area requirements; IRR exemption invalidated.

Case Summary (G.R. No. 180050)

Population Requirement Analysis

Section 461(a)(ii) of the Local Government Code requires a minimum of 250,000 inhabitants as certified by the NSO. At the time of creation, Dinagat Islands had only 106,951 inhabitants (2000 census) and 120,813 in 2007. The 2003 special census (371,576) was invalid for lack of NSO certification and failure to show that Surigao del Norte retained its minimum population.

Land Area Requirement Analysis

Section 461(a)(i) mandates a contiguous territory of at least 2,000 square kilometers as certified by the Lands Management Bureau. Dinagat Islands has only 802.12 km². Respondents’ reliance on IRR Article 9(2) exemption for island provinces was struck down as exceeding the statute, since Section 461 does not exempt island provinces from the minimum land area.

Distinct Contiguity and Size Requirements

Both Section 7(c) and Section 461(a)(i) establish two separate land area requisites: contiguity and sufficiency (2,000 km²). Section 461(b) dispenses only with contiguity when a province comprises two or more islands or is separated by non-contributing chartered cities; it does not dispense with the minimum size requirement.

Legislative Power and Constitutional Mandate

Article X, Section 10 of the Constitution vests in Congress the power to create provinces “in accordance with the criteria established in the local government code.” Any derogation from those criteria, including exemptions, must appear in the Code itself. No amendment to Section 461 has added an island-province land-area exemption.

Presumption of Validity and Judicial Review

Although every statute is presumed constitutional, courts must invalidate laws that clearly contravene constitutional or statutory mandates. Petitioners overcame the presumption by demonstrating non-compliance with Section 461’s explicit requisites.

Rejection of Operative Fact Doctrine

The Court refused to sustain R.A. 9355 under the operative fact doctrine. Despite the existence of a “fait accompli” (plebiscite results, elections, and formation of provincial government), the judiciary’s duty to nullify unconstitutional acts prevails over considerations of expediency.

Dissent on Exemption Interpretation and Legislative Intent

Justice Perez (dissenting) argued that income is the primary viability criterion and that Section 461(b)’s exemption for island provinces logically extends to both contiguity and minimum area. He relied on legislative debates prioritizing economic viability and on IRR Article 9’s explicit island-province land-area exemption as a valid executive construction under Section 533 of the Local Go
