Maceda vs. Macaraig, Jr.

The National Power Corporation (NPC) is exempt from indirect taxes (specific and ad valorem taxes) on petroleum products used in its operations under Section 13 of Presidential Decree No. 938, which grants exemption from "all forms of taxes," and the rule of strictissimi juris (strict construction of tax exemptions against the claimant) does not apply to tax exemptions granted to government-owned or controlled corporations.

The National Power Corporation (NPC) is a non-profit public corporation created to develop hydroelectric and other power sources for nationwide electrification. Since its creation under Commonwealth Act No. 120, it enjoyed broad tax exemptions to facilitate payment of its obligations and keep electricity rates low. The case arose from conflicting interpretations of whether NPC's tax exemption covered indirect taxes (taxes paid by oil companies/manufacturers but shifted to NPC through the purchase price of petroleum products). Billions of pesos in claims for tax refunds and credit certificates were at stake, which the petitioner alleged constituted illegal expenditure of public funds and tax evasion by oil companies (Caltex, Shell, Petrophil).

• The National Power Corporation (NPC) was created by Commonwealth Act No. 120 on November 3, 1936, and granted tax exemptions under Republic Act No. 358 (June 4, 1949) to facilitate payment of its indebtedness.
• Republic Act No. 6395 (September 10, 1971) revised the NPC charter, declaring it a non-profit corporation and exempting it from all taxes, duties, fees, imposts, and charges on all petroleum products used in its operations.
• Presidential Decree No. 380 (January 22, 1974) amended Section 13 of R.A. No. 6395 to specifically exempt NPC from taxes imposed "directly or indirectly" on petroleum products used in its operations.
• Presidential Decree No. 938 (May 27, 1976) further amended Section 13, integrating the exemption into general terms covering "all forms of taxes, duties, fees, imposts," but deleted the specific phrases "directly or indirectly" and "on all petroleum products used by the Corporation."
• Presidential Decree No. 1931 (June 11, 1984) withdrew all tax exemption privileges of government-owned or controlled corporations but empowered the President and/or Minister of Finance, upon recommendation of the Fiscal Incentives Review Board (FIRB), to restore such exemptions.
• FIRB Resolution No. 10-85 (February 7, 1985) restored NPC's tax and duty exemption privileges retroactively from June 11, 1984, to June 30, 1985; FIRB Resolution No. 1-86 (January 7, 1986) restored them indefinitely effective July 1, 1985.
• Executive Order No. 93 (December 17, 1986) withdrew all tax and duty incentives but authorized the FIRB to restore exemptions with the approval of the President.
• FIRB Resolution No. 17-87 (June 24, 1987) restored NPC's tax exemption privileges including those pertaining to domestic purchases of petroleum products, effective March 10, 1987, which was confirmed by the Executive Secretary on October 5, 1987.
• Oil companies (Caltex, Shell, Petrophil) paid specific and ad valorem taxes to the Bureau of Internal Revenue (BIR) and customs duties to the Bureau of Customs (BOC) on petroleum products sold to NPC, billing NPC "net of tax," with NPC later applying for tax credits or refunds which were assigned to the oil companies.
• The BIR issued conflicting rulings on whether NPC's exemption covered indirect taxes, initially ruling it did not (BIR Ruling No. 186-85), then later ruling it did.
• Petitioner, as a taxpayer and Senator, filed suit to stop the release of approximately P1.58 billion in tax refunds, alleging the exemptions were illegal and constituted tax evasion by the oil companies.

• As a taxpayer and Senator, petitioner has standing to file the suit to prevent illegal expenditure of public money involving tax refunds totaling billions of pesos.
• Presidential Decree No. 938 repealed the exemption from indirect taxes previously granted under P.D. No. 380 by deleting the phrases "directly or indirectly" and "on all petroleum products used by the Corporation," leaving only an exemption from direct taxes.
• Under the doctrine in Philippine Acetylene Co. v. Commissioner of Internal Revenue, tax exemptions cover only taxes for which the taxpayer is directly liable, not taxes merely shifted to it; thus, NPC cannot claim exemption from taxes paid by oil manufacturers.
• The rule of strictissimi juris applies: tax exemptions must be strictly construed against the taxpayer and liberally in favor of the taxing authority.
• Executive Order No. 93 constitutes an undue delegation of legislative power to the FIRB to restore tax exemptions, which is unconstitutional.
• The tax refunds to NPC, which are assigned to oil companies, effectively allow the oil companies to evade taxes and constitute a drain on public revenue.

• Petitioner lacks standing because he has not shown direct injury, only a general interest common to all citizens; the proper remedy is an appeal to the Court of Tax Appeals under R.A. No. 125, not certiorari.
• Mandamus does not lie to compel the Commissioner of Internal Revenue to impose a tax assessment, as it would usurp executive functions.
• The phrase "all forms of taxes" in P.D. No. 938 is expansive and includes both direct and indirect taxes; the deletion of specific references was for simplification and integration, not repeal.
• The rule of strict construction does not apply to exemptions granted to government instrumentalities like NPC; such exemptions may be construed liberally.
• Legislative intent, as shown by the preamble of P.D. No. 938, was to strengthen NPC's preferential tax treatment, not restrict it.
• FIRB Resolutions No. 10-85 and 1-86 were validly approved by the Minister of Finance (who was also FIRB Chairman) under P.D. No. 1931; FIRB Resolution No. 17-87 was validly approved by the President through the Executive Secretary.
• The delegation of power to the FIRB under E.O. No. 93 is constitutional because sufficient standards are provided (public interest, price levels, revenue generation, etc.).
• The tax exemption benefits the consuming public by keeping electricity rates low, not the oil companies, as NPC does not pass on the tax component to consumers.

• Procedural Issues: Whether petitioner has standing to sue as a taxpayer; Whether certiorari, prohibition, and mandamus are proper remedies to challenge tax refund orders.
• Substantive Issues: Whether P.D. No. 938 repealed NPC's exemption from indirect taxes; Whether NPC is entitled to exemption from indirect taxes on petroleum products; Whether the rule of strictissimi juris applies to government-owned corporations; Whether FIRB Resolutions No. 10-85, 1-86, and 17-87 are valid; Whether E.O. No. 93 constitutes an undue delegation of legislative power.

• Procedural: The Court held that petitioner has standing as a taxpayer under the Lozada doctrine because the petition involves illegal expenditure of public money in the form of tax refunds to NPC; Certiorari and prohibition are proper remedies to prevent an unlawful exercise of jurisdiction or oppressive exercise of legal authority; Mandamus may lie to control the discretion of revenue officials when exercised arbitrarily or with grave abuse beyond statutory authority.
• Substantive: The Court held that P.D. No. 938's grant of exemption from "all forms of taxes" includes indirect taxes on petroleum products; Repeal by implication is not favored, and the legislative intent was to expand, not restrict, NPC's tax exemption; The rule of strictissimi juris does not apply to tax exemptions granted to government instrumentalities or political subdivisions; FIRB Resolution No. 17-87 is valid as it was duly approved by the President; FIRB Resolutions No. 10-85 and 1-86 are valid as they were approved by the Minister of Finance acting under the authority of P.D. No. 1931, which superseded the earlier requirement of Presidential approval only; The delegation of power to the FIRB under E.O. No. 93 is constitutional because sufficient standards are provided in Section 3 thereof (effect on price levels, revenue generation, national interest).

• Taxpayer's Suit — A taxpayer has standing to sue to prevent the illegal disbursement of public funds or to compel restitution of public money illegally expended, even without showing direct personal injury, provided the case involves public funds and illegal expenditure. This doctrine was applied to allow petitioner to challenge the tax refunds to NPC.
• Strictissimi Juris (Exception for Government Instrumentalities) — While tax exemptions are generally construed strictly against the claimant, this rule does not apply to exemptions granted to government political subdivisions or instrumentalities; such exemptions may be construed liberally because the practical effect is merely to reduce the amount of money the government handles in its operations.
• Indirect Tax Exemption — A tax exemption granted to a government corporation covering "all forms of taxes" includes indirect taxes (taxes for which the corporation is not directly liable but which are shifted to it by suppliers), where the legislative intent is to provide comprehensive tax relief to enable the corporation to fulfill its public purpose.
• Delegation of Legislative Power — Delegation of legislative power to an administrative body is valid if the law provides sufficient standards, which may be express or implied from the policy and purpose of the act; the standard of "public interest," "national interest," or similar broad terms may be sufficient.
• Repeal by Implication — Repeal by implication is not favored unless the intent to repeal is manifest and the repugnancy between the new law and the old law is clear and convincing; courts must attempt to reconcile or adjust provisions to give sensible effect to both.

• "The Court however agrees with the petitioner that as a taxpayer he may file the instant petition following the ruling in Lozada when it involves illegal expenditure of public money."
• "The use of the phrase 'all forms' of taxes demonstrate the intention of the law to give NPC all the tax exemptions it has been enjoying before."
• "It is a recognized principle that the rule on strict interpretation does not apply in the case of exemptions in favor of a government political subdivision or instrumentality."
• "The greater interest of the people must be paramount."
• "This is because P.D. No. 938 which is the latest amendment to the NPC charter granting the NPC exemption from all forms of taxes certainly covers real estate taxes which are direct taxes."

• Lozada v. Commission on Elections (120 SCRA 337) — Cited as controlling precedent for taxpayer standing in cases involving illegal expenditure of public money.
• Philippine Acetylene Co., Inc. v. Commissioner of Internal Revenue (20 SCRA 1056) — Distinguished and held inapplicable; this case held that tax exemption covers only taxes for which the taxpayer is directly liable, but the Court ruled that subsequent amendments to the NPC charter (R.A. No. 6395, P.D. No. 380, P.D. No. 938) expanded the exemption to cover indirect taxes, effectively superseding the Acetylene ruling as applied to NPC.
• National Power Corporation v. Province of Albay (G.R. No. 87479, June 4, 1990) — Modified or superseded to the extent it held that FIRB Resolutions No. 10-85 and 1-86 were invalid for lack of Presidential approval; the Court held that approval by the Minister of Finance was sufficient under P.D. No. 1931.
• Meralco Securities Corporation v. Savellano (117 SCRA 804) — Cited for the principle that mandamus may control the discretion of revenue officials when exercised arbitrarily or with grave abuse.
• Edu v. Ericta and De la Llana v. Alba — Cited for the doctrine that the standard for valid delegation of legislative power may be express or implied.

• Section 13 of Republic Act No. 6395 (as amended by P.D. No. 380 and P.D. No. 938) — The primary provision granting NPC exemption from taxes; P.D. No. 380 specified exemption from taxes "directly or indirectly" imposed, while P.D. No. 938 exempted NPC from "all forms of taxes."
• Presidential Decree No. 1931 (Sections 1 and 2) — Withdrew tax exemptions of government-owned or controlled corporations but authorized the President and/or Minister of Finance, upon FIRB recommendation, to restore them.
• Executive Order No. 93 (Sections 1, 2, and 3) — Withdrew tax incentives but authorized the FIRB to restore them with Presidential approval; Section 3 sets the standards (price levels, revenue generation, national interest) for the FIRB's actions.
• Section 7 of Republic Act No. 125 (Court of Tax Appeals Act) — Cited by respondents regarding appeals from decisions of the Commissioner of Internal Revenue; the Court held this inapplicable as petitioner was not a taxpayer adversely affected by a Commissioner's decision.
• Section 28(4), Article VI of the 1987 Constitution — Requires the concurrence of a majority of all members of Congress to pass a law granting tax exemptions; cited by dissent regarding the stringent requirements for tax exemption legislation.
• Section 3, Article XVIII (Transitory Provisions) of the 1987 Constitution — Provides that existing laws, decrees, and executive orders not inconsistent with the Constitution remain operative until amended, repealed, or revoked.

• N/A (Justices Narvasa, Melencio-Herrera, Feliciano, Bidin, Medialdea, and Regalado concurred with the majority opinion without writing separate opinions).

• Justice Isagani A. Cruz — Argued that Presidential Decree No. 938 deleted the reference to "indirectly" imposed taxes, signifying legislative intent to repeal the indirect tax exemption; contended that P.D. Nos. 1931 and 1955 were invalid as they were presumably promulgated under Amendment No. 6 without justification, and that Executive Order No. 93 involved an invalid sub-delegation of legislative power; maintained that strict construction should apply because the ultimate beneficiaries of the tax refunds were the oil companies, not NPC.
• Justice Abraham F. Sarmiento — Argued that the deletion of the words "directly or indirectly" in P.D. No. 938 was significant and indicated an intent to exclude indirect taxes from the exemption; contended that FIRB Resolutions No. 10-85 and 1-86 were merely recommendatory and required separate approval by the President (not just the Minister of Finance) to be valid; warned that the decision would open the floodgates for NPC's suppliers, contractors, and other service providers to claim similar exemptions, resulting in massive revenue loss.
• Justice Pedro A. Paras — Dissented on the ground that while NPC should be refunded, the refund should come from the oil companies, not the consuming public, because the oil companies ultimately received the benefit of the tax exemption through the tax credit assignments.
