G.R. No. 188497 - Commissioner of Internal Revenue vs. Pilipinas Shell Petroleum Corp.

Case Summary (G.R. No. 188497)

Procedural History

The CTA En Banc rendered a decision dated March 25, 2009 and a related resolution dated June 24, 2009 in favor of Pilipinas Shell. The Supreme Court, in a decision promulgated April 25, 2012, granted the petition for review filed by the Commissioner of Internal Revenue and reversed the CTA, denying Pilipinas Shell’s refund claims. Pilipinas Shell filed reconsideration motions (May and December 2012). The Solicitor General filed a comment; Pilipinas Shell replied. On reconsideration, the Court (resolution in the record) granted Pilipinas Shell’s motions and ordered refund or tax credit issuance for excise taxes paid on petroleum products sold to international carriers for the period October 2001 to June 2002.

Issues Presented

Whether Section 135(a) of the National Internal Revenue Code (NIRC) exempts the petroleum products themselves from excise tax when sold to international carriers (and thus whether a local manufacturer who prepaid excise tax is entitled to refund).
Whether the exemption under Section 135(a) is conferred on the purchaser (international carrier) only, thereby precluding the manufacturer from claiming refund or credit of excise taxes already paid.
The proper interplay of domestic excise-tax rules with international obligations (Chicago Convention and bilateral air service agreements) and the economic effects of the Court’s construction.

Applicable Law and International Instruments

Primary statutory provisions considered: NIRC of 1997 — Sections 129, 130(A)(2), 135(a), 148(g), and Section 204(c) on refunds/credits. International law considerations: Article 24 of the 1944 Chicago Convention on International Civil Aviation and relevant ICAO policy statements and resolutions interpreting Article 24 to extend exemptions to duties and taxes on fuel for international carriage. Legislative action: Republic Act No. 10378 (granting reciprocal tax incentives to international carriers) and relevant Bureau of Internal Revenue (BIR) regulations cited in the record. The decision treats the NIRC within the constitutional framework applicable to decisions rendered after 1987.

Respondent’s Principal Contentions

Pilipinas Shell argued that Section 135(a) plainly exempts petroleum products sold to international carriers from excise tax, meaning no excise tax was ever due on those products and any excise tax paid prior to sale was erroneously paid and refundable. It emphasized that excise tax is an indirect tax and that, unlike VAT, exemption must be interpreted as attaching to the product at the point of production/removal. Shell further contended that preventing manufacturers from recovering prepaid excise taxes or prohibiting passing the tax to purchasers would inflict significant economic harm on domestic petroleum producers, place them at a competitive disadvantage relative to foreign producers, encourage tankering, and undermine participation of Filipino capital and labor in the industry. Shell also relied on international obligations under the Chicago Convention and bilateral agreements, asserting that domestic imposition of excise taxes on fuel sold to international carriers violated those commitments.

Petitioner’s (CIR) and Solicitor General’s Position

The Solicitor General argued that Section 135(a) does not attach the exemption to the goods such that the manufacturer is relieved of its statutory liability to pay excise tax upon removal. The Solicitor General relied on the established principle that when an excise tax imposed on the statutory taxpayer (manufacturer) is passed on to the purchaser it becomes part of the purchase price (citing Exxonmobil and related jurisprudence), and that prior jurisprudence (Philippine Acetylene; Maceda v. Macaraig, Jr.) confirms that Section 135(a) was intended to prevent manufacturers from shifting an excise tax component to international carriers rather than to relieve manufacturers of liability or to authorize refunds absent explicit statutory grant.

Nature of Excise Tax and Accrual Rules as Discussed by the Court

The Court reiterated the statutory character of excise taxes under the NIRC: they are taxes “applicable to certain specified goods or articles manufactured or produced in the Philippines” (Section 129), with two categories (specific and ad valorem). Aviation fuel is a specific excise tax under Section 148(g) that is treated as attaching to the product “as soon as they are in existence as such.” The Code requires that excise returns be filed and excise tax paid by the manufacturer or producer before removal of domestic products from place of production (Section 130(A)(2)). Thus the manufacturer bears the legal liability to pay excise tax at accrual, even though the tax is indirect in economic effect and may be passed on to buyers as part of the selling price.

Tension in Precedent and Statutory Interpretation

The Court identified a tension between longstanding jurisprudence holding that the statutory taxpayer (manufacturer) is the proper party to seek refund of erroneously paid indirect taxes and a different practical consideration: international law obligations (Chicago Convention and ICAO policy) require broad protection against taxation of aviation fuel used in international transport. Cases such as Silkair and Exxonmobil were examined, which underscore that the manufacturer remains the taxpayer and that the economic incidence of tax shifting does not alter legal liability. Conversely, international instruments and policy concerns weigh in favor of treating fuel sold for consumption in international carriage as effectively exempt and, where manufacturers have prepaid excise, eligible for refund or credit.

International Law, Policy Considerations, and Economic Impact

The Court placed significant emphasis on the international legal framework and policy considerations: Article 24 of the Chicago Convention, ICAO resolutions and policy documents, and bilateral air service agreements create strong reciprocal expectations that aviation fuel for international carriage not be subject to national or local duties, taxes, or similar charges. The Court noted the practical consequences of imposing or enforcing excise taxes on such fuel — including the encouragement of tankering (filling in low-tax jurisdictions), potential reduction in supply to international carriers, production retrenchment, adverse effects on tourism and trade, and risk of reciprocal or retaliatory measures — and treated these international policy and economic implications as relevant to statutory construction of Section 135(a).

Reconsideration Reasoning and Holding

Balancing statutory text, prior jurisprudence, and international obligations and consequences, the Court found merit in Pilipinas Shell’s reconsideration motions. The resolution re-examined the effect of denying manufacturers a refund of excise taxes already paid when the products were sold to carriers entitled to exemption. The Court concluded that when petroleum products subject to excise tax are sold to international carriers for use or consumption outside the Philippines and stored/handled as prescribed by law, the tax-exempt character of those products comes into full force upon sale to such carriers. Because Pilipinas Shell, as the statutory taxpayer, had paid excise taxes upon removal but the products were thereafter sold to exempt international carriers, the Court held Pilipinas Shell’s payments were erroneous with respect to those transactions and that it was therefore entitled to refund or tax credit under Section 204(c) and applicable jurisprudence. The Court directed the Commissioner of Internal Revenue to refund or issue a tax credit certif

Case Syllabus (G.R. No. 188497)

Procedural History

Case originally decided by this Court in a Decision promulgated April 25, 2012, which granted the petition for review on certiorari filed by the Commissioner of Internal Revenue (CIR) and reversed and set aside the Court of Tax Appeals (CTA) En Banc Decision dated March 25, 2009 and Resolution dated June 24, 2009 in CTA EB No. 415, thereby denying Pilipinas Shell Petroleum Corporation’s claims for tax refund or credit for lack of basis.
Pilipinas Shell filed a Motion for Reconsideration dated May 22, 2012 and a Supplemental Motion for Reconsideration dated December 12, 2012 following the April 25, 2012 Decision.
The Solicitor General, on behalf of the CIR, filed a Comment; respondent filed a Reply.
On reconsideration, the Court reexamined the issues and, by Resolution, granted Pilipinas Shell’s original and supplemental motions for reconsideration, affirmed the CTA En Banc Decision dated March 25, 2009 and the CTA Resolution dated June 24, 2009, and directed the CIR to refund or issue a tax credit certificate to Pilipinas Shell in the amount of P95,014,283.00 representing excise taxes paid on petroleum products sold to international carriers from October 2001 to June 2002.

Relevant Statutory Provisions

Section 135(a), National Internal Revenue Code (NIRC) — provides that petroleum products sold to international carriers of Philippine or foreign registry on their use or consumption outside the Philippines are exempt from excise tax, with storage in bonded tanks and disposition subject to rules and regulations.
Section 148(g), NIRC — imposes a specific excise tax on aviation jet fuel, described as attaching to the product “as soon as they are in existence as such.”
Section 129, NIRC — defines excise taxes as applied to goods manufactured or produced in the Philippines for domestic sale or consumption or for any other disposition and to things imported.
Section 130(A)(2), NIRC — provides that excise tax return shall be filed and excise tax paid by the manufacturer or producer before removal of domestic products from the place of production.
Section 130(4)(D), NIRC — provides for credit or refund of excise tax on goods actually exported, upon proof of actual exportation and receipt of corresponding foreign exchange payment.
Section 204(c), NIRC — authorizes the Commissioner to credit or refund taxes erroneously or illegally received upon written claim within two years after payment.
Section 22(N), NIRC — defines “taxpayer” as “any person subject to tax.”

Factual Background

Pilipinas Shell, a domestic petroleum manufacturer, paid excise taxes on petroleum products under Title VI of the NIRC, prior to removal from place of production, consistent with statutory requirement that manufacturer pays excise tax before removal.
Respondent sold petroleum products, including aviation fuel (jet A-1) and aviation gas, to various international carriers for use or consumption outside the Philippines.
Respondent claimed refund or credit of excise taxes it had paid on those sales on the basis that Section 135(a) exempts petroleum products sold to international carriers from excise tax.
Period of claimed refund: October 2001 to June 2002; amount claimed and ultimately ordered refunded/credited: P95,014,283.00.

Issues Presented

Whether the excise tax exemption under Section 135(a) of the NIRC attaches to the petroleum products themselves (so that the manufacturer is not liable for excise tax when such products are sold to international carriers) or whether the exemption is conferred on the international carriers (thus only prohibiting manufacturer from passing on the excise tax to those carriers).
Whether a domestic manufacturer who paid excise tax on petroleum products sold to international carriers may claim refund or credit of excise taxes paid.
Whether prior jurisprudence, Bureau of Internal Revenue (BIR) and CTA rulings interpreting Section 135 support the view that the exemption attaches to the article (product) or to the purchaser (international carrier).
Whether permitting refund to the manufacturer would be consistent with international obligations under the Chicago Convention and bilateral air service agreements, and whether denying refund would have adverse economic impact on the domestic oil industry and international air transport.

Arguments of Respondent (Pilipinas Shell)

Section 135 of the NIRC should be read plainly to mean petroleum products sold to international carriers are exempt from excise tax; hence no excise tax is due in the first place on such products.
Because excise tax is an indirect tax, Section 135 in relation to Section 148 should be interpreted as an exemption from the point of production and removal, since excise tax is imposed at that point; unlike VAT which is imposed at every turnover point, excise exemption must therefore attach to the product at production so the manufacturer need not pay the tax.
Exemption could only refer to the imposition of the tax on the statutory seller (the manufacturer), because when a tax paid by the statutory seller is passed on to the buyer it becomes an added cost to the price and is no longer “in the nature of a tax.”
The Court’s earlier ruling (that Section 135 only prohibits shifting the burden to international carriers) has adverse economic impact, curtails domestic oil industry competitiveness, forces absorption of tax by local manufacturers (contrary to State policy to protect dealers/distributors), and places domestic manufacturers at competitive disadvantage versus foreign oil producers whose governments exempt them under bilateral agreements.
Denial of refund could lead to cessation of supply to international carriers, retrenchment, or shutdown of production of jet fuel and aviation gas, diminishing Filipino participation in the domestic oil industry.
Imposition of excise tax on petroleum products sold to international carriers would violate the Chicago Convention and bilateral air transport agreements to which the Philippines is a signatory.

Arguments of Petitioner (CIR / Solicitor General)

The exemption under Section 135(a) does not attach to the petroleum products; it is conferred on international carriers as the buyers, and Section 135 should be construed as prohibiting manufacturers from shifting the excise tax burden to international carriers.
Cited Exxonmobil Petroleum & Chemical Holdings, Inc. — holding that excise tax when passed on to purchaser becomes part of purchase price — to refute respondent’s theory that the exemption attaches to the product (it would be erroneous for the seller to pay the excise tax and inequitable to pass it on if the exemption attached to the product).
Pointed out that Silkair and Exxonmobil rulings did not pronounce that manufacturers selling petroleum products to international carriers are exempt from paying excise taxes; Exxonmobil cited Philippine Acetylene Co. to the effect that manufacturers are not exempt.
Relied on Maceda v. Macaraig, Jr. confirming that Section 135 does not intend to exempt manufacturers or producers from payment of excise tax.
Emphasized statutory scheme: excise tax accrues and is payable by manufacturer on removal; no provision authorizes refund or credit to manufacturer for taxes it paid merely because purchaser is exempt.

Court’s Initial Decision (April 25, 2012) — Summary

Held that the CTA erred in granting respondent’s claim for tax refund because Pilipinas Shell failed to establish a tax exemption in its favor under Section 135(a) of the NIRC.
Concluded that the exemption under Section 135(a) is conferred on international carriers who purchased petroleum products for use or consumption outside the Philippines, not on the
