Prior Public Use and the Power of Expropriation: The NGCP Case

The power of eminent domain allows the State to take private property for public use upon payment of just compensation. But what happens when the property sought to be expropriated is already devoted to a public purpose? In PNOC Alternative Fuels Corporation v. National Grid Corporation of the Philippines (G.R. No. 224936, September 4, 2019), the Supreme Court settled this question, ruling that property already devoted to public use may still be expropriated for another public purpose—provided the expropriating entity has the authority to do so.

The Case

The National Grid Corporation of the Philippines (NGCP) sought to expropriate a portion of the Petrochemical Industrial Park in Bataan to construct the Mariveles-Limay 230 kV Transmission Line Project. The property was owned by PNOC Alternative Fuels Corporation (PAFC), a subsidiary of the Philippine National Oil Company (PNOC).

NGCP invoked its right of eminent domain under Section 4 of Republic Act No. 9511, its legislative franchise. This provision authorizes NGCP to exercise eminent domain "insofar as it may be reasonably necessary for the construction, expansion, and efficient maintenance and operation of the transmission system and grid."

PAFC opposed the expropriation, arguing that the property was already devoted to public use—specifically, the development of the petrochemical industry, which PAFC claimed was essential to national interest. PAFC insisted that only Congress could expropriate property already devoted to a public purpose.

The Issue

The central question was whether NGCP, a private corporation holding a legislative franchise, could expropriate property that PAFC argued was already devoted to public use.

The Ruling

The Supreme Court ruled in favor of NGCP, affirming the trial court's order of expropriation. The Court held that property already devoted to public use is not immune from expropriation, provided the taking is done directly by Congress or under a specific grant of authority.

Delegated Power is Limited

The Court emphasized that while the power of eminent domain is inherent in the State, private corporations like NGCP do not possess this power inherently. Their authority to expropriate is a mere delegation from Congress and must be exercised strictly within the limits of the delegating law.

Section 4 of R.A. No. 9511 explicitly states that NGCP "may acquire such private property as is actually necessary" for its franchise purposes. The Court applied the plain-meaning rule, holding that this provision is clear and unambiguous—NGCP can only expropriate private property.

The Property Was Private, Not Public

The key issue then became whether the subject property was private or public in nature. PAFC argued that because the property was part of an industrial zone devoted to petrochemical development, it was land of public dominion.

The Court disagreed. Under Article 420 of the Civil Code, property of public dominion includes those intended for public use, public service, or the development of national wealth. A defining characteristic of such property is inalienability—it cannot be sold, leased, or otherwise disposed of.

However, the Court found that the Petrochemical Industrial Park was expressly declared alienable and disposable by law. Presidential Decree No. 949, as amended by R.A. No. 10516, explicitly allowed PNOC to "lease, sell and/or convey" portions of the industrial zone to private entities. This declaration of alienability converted the property from public dominion to patrimonial property—property owned by the State in its private or proprietary capacity.

The Court noted that the management and operation of the industrial estate was commercial in nature, serving the economic ends of the State rather than sovereign functions. As patrimonial property, the land assumed the nature of private property and could therefore be expropriated by NGCP.

Necessity of the Taking

The Court also found that the expropriation was reasonably necessary. PAFC did not dispute the necessity of the transmission line project, and the parties had even entered into a Tripartite Agreement acknowledging the increased demand for electricity in Bataan and Zambales.

Practical Takeaways

• Property devoted to public use is not automatically immune from expropriation. It can still be taken for another public purpose, provided the expropriating authority has the legal power to do so.

• The distinction between public dominion and patrimonial property matters. Land declared alienable and disposable by the State ceases to be public dominion and becomes patrimonial property, which is treated as private property for purposes of expropriation.

• Delegated eminent domain is strictly construed. Private corporations and agencies exercising delegated expropriation powers must act within the precise limits of their authorizing law. If a franchise limits expropriation to "private property," that limitation is binding.

• The necessity of the taking is subject to judicial review. When expropriation is done by a delegate rather than directly by Congress, courts may examine whether the taking is reasonably necessary for the public purpose.

• Material allegations not specifically denied are deemed admitted. In expropriation cases, failing to deny allegations about the necessity of the taking can weaken a property owner's defense.
