Case Summary (G.R. No. 168732)

NAPOCOR’s Plea and Counterarguments

NAPOCOR denied material allegations, argued respondents never possessed the sub-terrain portions and thus could not seek damages for deprivation, contested respondents’ proof of ownership, and characterized the tunnels as government works serving public use that either created an easement or otherwise subjected private lands to necessary burdens for a public project. NAPOCOR also raised procedural defenses in the course of appeal and post-judgment motions.

RTC Judgment (August 7, 1996): Findings and Awards

The Regional Trial Court found for respondents and ordered NAPOCOR to pay just compensation for 48,005 sq. m. at P1,000 per sq. m. (total P48,005,000.00) with 6% interest per annum from filing, reasonable monthly rentals computed at P0.68 per sq. m., P200,000.00 as moral damages, and P200,000.00 as attorney’s fees and costs. The RTC expressly denied respondents’ prayer to dismantle the underground tunnels.

Post-Judgment Proceedings and Modified Judgment (September 8, 1997)

Following execution pending appeal and disputes over appeal filings, certain respondents filed for relief from judgment asserting mistake and excusable negligence regarding the nature of the decree (they believed initially the judgment awarded only rentals and fees, not just compensation). The RTC granted relief, reduced the monetary awards by specified amounts, ordered certain rentals as deductible, and left a balance subject to later execution, while maintaining awards for moral damages and attorney’s fees as modified.

Appeals and Court of Appeals Disposition (June 8, 2005)

Both sides appealed to the Court of Appeals. The CA set aside the RTC’s modified judgment, reinstated the original August 7, 1996 decision, and further modified it by deleting the award of moral damages and reducing rentals and attorney’s fees (reduced attorney’s fees to P50,000.00 and rentals to a revised figure). The CA also directed reassessment of additional filing fees.

Issues Raised in the Supreme Court Petition

NAPOCOR’s petition for review on certiorari presented two principal contentions: (a) respondents were not deprived of beneficial use of their properties and therefore were not entitled to just compensation; and (b) even if entitled, the award was improperly computed because the valuation should be as of 1978 (time of alleged taking) and petitioner challenged the P1,000 per sq. m. figure and the propriety of awarding back rentals.

Standard of Review and Scope of Supreme Court Review

The Supreme Court reiterated the well-settled limitation on Rule 45 review: it does not generally revisit factual findings of the lower courts absent grave abuse of discretion. Jurisprudence limits the Court’s review of factual determinations made by trial and appellate courts; petitioner failed to demonstrate any grave abuse of discretion by the RTC or CA. Thus, the CA’s and RTC’s factual findings on ownership, possession, and the existence and effect of the tunnels were treated as conclusive.

Ownership of Sub-Terrain and Legal Foundation

The Court affirmed the principle in Civil Code Art. 437 that ownership of land extends to the surface and everything under it. Citing prior decisions, the Court rejected any doctrine that divides surface and subsoil ownership into distinct, separable rights that would permit a conflicting practical regime. Accordingly, the lower courts’ findings that respondents owned the surface and that petitioner occupied the substrata since 1978 were sustained; respondents therefore had ownership rights over the sub-terrain.

Taking, Eminent Domain, and Due Process Considerations

The Court analyzed whether NAPOCOR’s subterranean works amounted to a taking that required due process and payment of just compensation. It held that even if the occupation could be characterized as an easement, NAPOCOR violated respondents’ due process rights because the easement was imposed without notice, indemnity, or formal expropriation proceedings. The power of eminent domain — when properly invoked — covers both complete takings and impositions of burdens (easements) and requires that takings for public use be accompanied by payment of just compensation and compliance with due process. Because NAPOCOR did not follow such procedure, it risked liability and could be required to pay full compensation where the imposed burden practically deprived owners of normal beneficial use.

Practical Effect of the Tunnels on Use and Value

The trial court found and the CA sustained that the underground tunnels materially interfered with respondents’ use of the land: refusal of a deep-well permit, denial of bank loan collateral acceptance, and evident danger due to geologic instability were concrete examples. That interference amounted to deprivation of ordinary use and significant diminution in value, supporting the conclusion that respondents were entitled to just compensation comparable to full land value rather than a mere easement fee.

Date of Taking and Valuation Rule

The Court reiterated the governing rule on valuation in expropriation: the general rule fixes just compensation as of the date of filing of the complaint (Rule 67, Sec. 4), but recognized exceptions where valuation as of the date of actual taking is appropriate if justified. The Court applied the principles from precedents (including Mangondato) to determine the date relevant for valuation. It found that NAPOCOR’s initial entrance
