Case Summary (G.R. No. 210191)

Key Dates and Procedural Posture

Relevant agreements: Energy Conversion Agreement (ECA) dated May 20, 1994; Memorandum of Agreement (MOA) dated December 3, 1994. Plant commencement: Mirant began operations in 1998. NPC paid real property taxes through first quarter 2003; a Notice of Assessment was issued September 10, 2003. Administrative proceedings: LBAA decisions (April 15, 2004 and July 18, 2007); CBAA consolidated decision and dismissal (April 12, 2012; reconsideration denied July 31, 2012); CTA En Banc decision affirmed LBAA/CBAA (November 11, 2013). Final judicial review: Petition for review under Rule 45 to the Supreme Court; petition denied (G.R. No. 210191).

Applicable Law and Constitutional Basis

Governing statute: Local Government Code (R.A. No. 7160) — relevant provisions invoked include Section 206 (proof of exemption), Section 216 (special classes of real property), Section 217 (basis of assessment), Section 225 (depreciation allowance for machinery), and Section 234 (exemptions from real property tax, subsections (c) and (e)). Procedural rule: Petition for Review on Certiorari under Rule 45, Rules of Court. Constitutional framework: decision rendered under the 1987 Philippine Constitution (decision date post-1990), with emphasis on the State policy recognizing local government autonomy and the fiscal prerogative of local government units to collect taxes.

Factual Background — Contractual Arrangement and Tax Undertaking

NPC entered into an ECA with CEPA/Mirant on a BOT (Build-Operate-Transfer) basis: Mirant would build, operate, and maintain the Sual coal-fired plant and supply electricity exclusively to NPC, with ownership of the power station, fixtures, machinery, and equipment vested in Mirant until the agreed Transfer Date, after which Mirant would transfer the plant to NPC without compensation. The MOA among NPC, Mirant/PEC, the Province of Pangasinan, Municipality of Sual and Barangay Pangascasan acknowledged certain responsibilities, including NPC’s agreement to conform with Local Government Code regulations and to pay realty tax upon project site acquisition.

Facts Concerning Tax Payments and Claim

NPC paid real property taxes on land, buildings, machinery and equipment from 1998 through Q1 2003. On Q2 2003 NPC stopped payment, invoking exemptions under R.A. No. 7160. The Municipal Treasurer issued a Notice of Assessment (September 10, 2003). NPC filed petitions before the LBAA claiming exemption under Section 234(c) (machinery and equipment used by government-owned corporations engaged in power generation/transmission), alternatively for classification as a special class under Section 216 for a lower assessment level, and claiming depreciation allowance under Section 225; NPC also asserted entitlement under Section 234(e) (machinery and equipment used for pollution control).

LBAA and CBAA Rulings

The LBAA dismissed NPC’s petitions, holding that NPC failed to timely file the required exemption claim under Section 206 and that NPC’s prior payment of taxes estopped it from asserting the exemption. Crucially, the LBAA and later the CBAA found Mirant to be the actual, direct, exclusive, and beneficial owner and user of the plant and its machineries and equipment during the taxable period; therefore NPC lacked the factual predicate to claim exemptions or reduced assessment. The CBAA consolidated the appeals and dismissed them for lack of merit, reiterating that Mirant — not NPC — was the owner-user entitled, if at all, to claim exemptions or privileges.

CTA En Banc Ruling and Reasoning

The Court of Tax Appeals (En Banc) affirmed the administrative boards. The CTA examined the ECA and concluded ownership and actual use of the machinery and equipment were vested in Mirant until transfer. Because the statutory exemptions and privileges under R.A. No. 7160 apply to property actually, directly, and exclusively used by local water districts or government-owned/controlled corporations engaged in specified services, NPC could not claim those benefits when it was neither the owner nor the actual user during the taxable period. The CTA rejected NPC’s estoppel argument against the respondents, noting the MOA did not acknowledge NPC as owner-user and that an undertaking by NPC to pay taxes does not transform the property’s legal character or extend NPC’s tax privileges to Mirant.

Central Legal Issue Presented

All contested questions — exemption under Sections 234(c) and 234(e), classification under Section 216 for lower assessment, and entitlement to depreciation allowance under Section 225 — reduce to whether NPC possessed the requisite legal personality and legal interest in the subject machineries and equipment to contest assessment and claim statutory tax privileges. The Court framed the pivotal inquiry as whether NPC was the actual, direct, exclusive, and beneficial user/owner during the assessed period.

Legal Analysis — BOT Characterization and Ownership Consequences

The Court applied the BOT concept as reflected in the ECA and prior precedents: under a BOT arrangement, the private proponent constructs, finances, operates and manages the facility and retains ownership and beneficial use during the concession period in order to recover investment and earn returns; ownership transfers to the government entity upon the agreed transfer date. The ECA provisions (notably Articles 2.10 and 2.11) unambiguously vested ownership of the power station and its machinery with Mirant until transfer and assigned operation/maintenance responsibilities to Mirant prior to transfer. The Court therefore held that the arrangement was not a mere service contract but a classic BOT, placing ownership and actual use with Mirant and rendering NPC’s claim of ownership and exclusive use untenable during the taxable period.

Application of Statutory Exemptions and Privileges

The Court reiterated statutory prerequisites: exemptions under Section 234(c) and classification under Section 216 require the claimant to be the entity actually, directly, and exclusively using the property for the enumerated public service (e.g., generation and transmission of electric power). Because Mirant was the owner-user, NPC failed to meet those elements. The Court emphasized that exemptions attach to the property as used by the qualifying entity; the fact that NPC receives and transmits electricity does not convert the machineries and equipment into NPC’s exempt property. Similarly, entitlement to depreciation allowance under Section 225 and exemption under Section 234(e) (pollution-control machinery) require legal and factual foundations tied to ownership or actual, direct and exclusive use, which NPC did not establish.
