G.R. No. 210191 - National Power Corp. vs. Province of Pangasi

Case Summary (G.R. No. 210191)

Factual Background

NPC is a government-owned and controlled corporation created under R.A. No. 6395 with the mandate to generate and transmit electric power. On May 20, 1994, NPC entered into an Energy Conversion Agreement (ECA) with CEPA Pangasinan Electric Limited, later Mirant Sual Corporation (Mirant), for the construction, operation, and maintenance of the Sual Coal-Fired Thermal Power Plant on a Build-Operate-Transfer (BOT) basis. Under the ECA NPC agreed to buy electricity generated by the plant from Mirant, who was to own, operate, and maintain the facility until the agreed transfer date.

Agreements and Tax Undertakings

The ECA expressly placed ownership of the power station, its fixtures, machinery, and equipment in Mirant from the date of the agreement until the transfer date, and provided for transfer to NPC on the transfer date without compensation. Paragraph 11.1 of Article 11 of the ECA additionally recorded NPC's undertaking to assume payment of all real property taxes in respect of the site, buildings, infrastructure, and power station. A Memorandum of Agreement dated December 3, 1994 among NPC, Mirant's predecessor, the Province of Pangasinan, the Municipality of Sual, and the Barangay of Pangascasan reiterated certain local obligations, including payment of realty tax upon project site acquisition by NPC.

Administrative Assessment and NPC's Claim

Mirant commenced operation of the plant circa 1998. NPC paid real property taxes for the land, buildings, machinery, and equipment from 1998 until the first quarter of 2003. NPC ceased payments in the second quarter of 2003 and subsequently invoked exemptions under R.A. No. 7160. Following the cessation, the Municipal Treasurer of Sual issued an Updated Notice of Assessment and Tax Bill. NPC filed petitions with the Local Board of Assessment Appeals (LBAA), docketed as LBAA Case Nos. P-03-001 and P-06-001, seeking recall of the assessment and asserting that the machinery and equipment were exempt under Section 234(c) or (e) of R.A. No. 7160, or alternatively that the properties should be classified as a special class under Section 216 for a lower assessment level.

LBAA Proceedings and Ruling

The LBAA dismissed NPC’s petitions. In its April 15, 2004 Resolution and later Order dated July 18, 2007, the LBAA found that NPC and Mirant failed to file any claim for exemption within thirty days from the declaration of the property as required by Section 206 of R.A. No. 7160, and that NPC’s prior payment of taxes estopped it from claiming exemption. The LBAA also found that Mirant, not NPC, was the actual, direct, exclusive, and beneficial owner and user of the power plant and its machinery and equipment; consequently the LBAA held that the properties were not exempt under Section 234(c) nor entitled to the special classification under Section 216 and should be assessed at eighty percent.

CBAA Proceedings and Ruling

NPC appealed to the Central Board of Assessment Appeals (CBAA). The CBAA consolidated NPC’s appeals and, by Decision dated April 12, 2012, dismissed them for lack of merit. The CBAA ruled that Mirant retained ownership and actual use of the facilities until transfer and that NPC thus lacked the legal personality to claim exemptions or privileges under Sections 234(c), 234(e), and 225 of R.A. No. 7160. The CBAA denied NPC’s motion for reconsideration on July 31, 2012.

Court of Tax Appeals Ruling

The Court of Tax Appeals reviewed the ECA and concluded that Mirant owned and actually used the machinery and equipment until transfer. The CTA sustained the LBAA and CBAA findings that NPC lacked the requisite legal interest to challenge the assessment or to claim the statutory exemptions and privileges under R.A. No. 7160. The CTA rejected NPC’s estoppel argument, noting that the MOA did not acknowledge NPC as owner or user of the plant and that an undertaking by NPC to pay taxes could not confer exemption. The CTA relied on prior precedents, including National Power Corporation v. Province of Quezon, and dismissed NPC’s appeal.

Issues Presented to the Supreme Court

NPC presented whether the subject machinery and equipment are exempt from real property tax under Sections 234(c) or 234(e) of R.A. No. 7160; whether the properties qualify as a special class under Section 216 for a lower assessment; and whether NPC is entitled to the depreciation allowance under Section 225. The Court distilled these inquiries to the pivotal legal question whether NPC possessed the legal personality and interest to claim the exemptions and privileges at issue.

Parties' Contentions

NPC contended that it had legal interest in the properties as project owner and that legal interest for taxation is not limited to ownership because assessment is based on actual use pursuant to Section 217 of R.A. No. 7160. NPC argued that beneficial use may impose tax liability and thus confer standing to contest assessments and claim exemptions. The Province and the Provincial Assessor maintained that Mirant was the owner, operator, and actual user of the facilities during the taxable period and that only the entity which is actually, directly, and exclusively using the machinery and equipment may claim the exemptions or reduced assessment levels under R.A. No. 7160.

The Court’s Disposition

The Court denied the petition and affirmed the CTA En Banc Decision dated November 11, 2013 in CTA EB Case No. 937. The Court held that NPC lacked the legal personality to invoke the claimed exemptions, special classification, or depreciation allowance under R.A. No. 7160 with respect to the subject machinery and equipment.

Legal Basis and Reasoning

The Court anchored its ruling on the plain terms of the ECA and on the doctrinal meaning of a BOT arrangement. The ECA provisions unambiguously vested ownership of the power station, fittings, machinery, and equipment in Mirant until the transfer date and entrusted Mirant with operation, management, and maintenance until transfer. The Court reiterated the BOT concept that the private proponent constructs, finances, owns, operates, and recovers its investment during the contract term and transfers the facility to the government at the end of the term. Applying this doctrine, the Court found Mirant to be the actual, direct, exclusive, and beneficial owner and user of the facilities during the taxable period, and NPC’s owner

Case Syllabus (G.R. No. 210191)

Parties and Procedural Posture

National Power Corporation filed a Petition for Review on Certiorari under Rule 45, Rules of Court, challenging the Court of Tax Appeals En Banc Decision dated November 11, 2013 in CTA EB Case No. 937.
The Province of Pangasinan and the Provincial Assessor of Pangasinan appeared as respondents in the administrative and judicial proceedings.
The petition sought review of consolidated administrative rulings of the Local Board of Assessment Appeals (LBAA) in LBAA Case Nos. P-03-001 and P-06-001 and the Central Board of Assessment Appeals (CBAA) in CBAA Case Nos. L-52 and L-81.
The CTA En Banc affirmed the LBAA and CBAA rulings and dismissed NPC's claims for exemption and related reliefs, prompting the present appeal.

Key Factual Allegations

NPC entered into an Energy Conversion Agreement (ECA) dated May 20, 1994 with CEPA Pangasinan Electric Limited, later known as Mirant Sual Corporation (hereafter Mirant), for a Build-Operate-Transfer power plant in Sual, Pangasinan.
Paragraph 11.1, Article 11 of the ECA provided that NPC would be responsible for the payment of certain real property taxes and assessments.
A Memorandum of Agreement (MOA) dated December 3, 1994 between NPC, PEC (Mirant’s predecessor), the Province, the Municipality of Sual, and the Barangay of Pangascasan contained a provision that NPC would pay realty tax upon project site acquisition.
Mirant constructed, operated, and maintained the power plant and held ownership of the power station and its machinery and equipment until the transfer date under the ECA.
NPC paid real property taxes for the plant from 1998 until the first quarter of 2003 and ceased payment beginning the second quarter of 2003, invoking exemptions under R.A. No. 7160.
The Municipal Treasurer of Sual issued a Notice of Assessment dated September 10, 2003 for unpaid real property taxes on the subject properties.

Claims and Legal Contentions

NPC claimed exemption of the subject machinery and equipment from real property tax under Section 234(c) and Section 234(e) of R.A. No. 7160, classification as a special class under Section 216 for a lower assessment level, and entitlement to the depreciation allowance under Section 225.
NPC contended that legal interest to assert tax exemptions is not limited to ownership and that beneficial use or project ownership sufficed to confer standing to challenge assessments under Section 217 of R.A. No. 7160.
Respondents maintained that Mirant, not NPC, was the actual, direct, exclusive, and beneficial owner and user of the machinery and equipment during the relevant period and that NPC therefore lacked legal personality to claim exemptions.
