Case Summary (G.R. No. 180909)

Factual Background and Administrative/Judicial Steps

Exxon purchased Jet A-1 fuel and other petroleum products from Caltex Philippines, Inc. (Caltex) and Petron Corporation (Petron). Caltex and Petron paid and remitted the excise taxes on the petroleum products, and those taxes were passed on to Exxon, which ultimately shouldered the excise taxes as part of the purchase price. From November 2001 to June 2002, Exxon sold a total of 28,635,841 liters of Jet A-1 fuel to international carriers, allegedly free of excise taxes amounting to Php105,093,536.47.

On various dates, Exxon filed administrative claims for refund with the Bureau of Internal Revenue (BIR) totaling Php105,093,536.47. On October 30, 2003, Exxon filed a petition for review with the CTA, docketed as CTA Case No. 6809, claiming a refund or tax credit of Php105,093,536.47, representing excise taxes paid on the Jet A-1 fuel and other petroleum products sold to international carriers from November 2001 to June 2002.

The parties later filed a Joint Stipulation of Facts and Issues on June 24, 2004, presenting fourteen (14) issues. During Exxon’s evidence preparation, the CIR filed a motion dated January 28, 2005 asking that the CTA resolve first whether Exxon was the proper party to seek a refund. Exxon opposed on March 15, 2005.

Proceedings Before the CTA First Division and CTA-En Banc

On July 27, 2005, the CTA First Division granted the CIR’s motion to resolve the preliminary issue on the proper party and dismissed Exxon’s claim for refund. Exxon moved for reconsideration, but it was denied on July 27, 2006.

Exxon then elevated the matter to the CTA-En Banc, assailing the July 27, 2005 resolution dismissing its petition for review and the July 27, 2006 resolution denying reconsideration. On September 7, 2007, the CTA-En Banc dismissed the petition for review and affirmed the CTA First Division rulings. Exxon’s motion for reconsideration was denied on November 27, 2007.

The CTA-En Banc anchored its ruling on Sections 130(A)(2) and 204(C) in relation to Section 135(a) of the NIRC. It held that, consistent with jurisprudence, only the taxpayer—identified as the manufacturer or producer of the petroleum products—has the legal personality to claim a refund of excise taxes paid on petroleum products sold to international carriers. The CTA reasoned that Section 130(A)(2) makes the manufacturer or producer directly liable for excise taxes, and therefore the manufacturer or producer is the taxpayer for purposes of refunds.

The CTA characterized the excise tax imposed on petroleum products upon removal by oil companies as an indirect tax. It explained that although the tax burden may be shifted to the purchaser, the statutory liability to pay remains with the manufacturer. It further emphasized that the manufacturer has the option whether to shift the burden, and when shifted, the amount becomes part of the price. Thus, it concluded that refunds for erroneously paid or illegally received indirect taxes can be claimed only by the taxpayer under Section 204(C), since refunds are in the nature of tax exemptions and are construed strictissimi juris against the claimant.

To support that view, the CTA cited Philippine Acetylene Co., Inc. v. Commissioner of Internal Revenue, Contex Corporation v. Commissioner of Internal Revenue, and Commissioner of Internal Revenue v. Philippine Long Distance Telephone Company for the proposition that indirect taxes are legally imposed upon the manufacturer and that the buyer, even if economically burdened, is not the taxpayer entitled to a refund. It also invoked Cebu Portland Cement Company v. Collector of Internal Revenue and Contex for the rule that in indirect taxes, the manufacturer is the party entitled to claim refunds.

Finally, the CTA rejected Exxon’s contention that the ruling effectively amended bilateral agreements in violation of pacta sunt servanda. The CTA reasoned that factual findings showed Exxon sold Jet A-1 fuel to international carriers free of tax, and that the exemption right of international carriers under Section 135(a) was not restricted at the point of sale; it added that the presumption stands that the lawmaking body enacted later legislation with knowledge of related laws.

Issues Raised on Appeal to the Supreme Court

Exxon raised two issues. First, it argued that the CTA decisions erroneously prohibited Exxon, as distributor and vendor to international carriers registered in foreign countries with bilateral agreements with the Philippines, from claiming a refund of excise taxes paid. Second, it asserted that the CTA erred in affirming the dismissal because the CIR’s motion to resolve first whether Exxon was the proper party was allegedly in substance a motion to dismiss filed out of time and should have been denied outright.

Supreme Court Review: Validity of the “Motion to Resolve First” and the Proper-Party Issue

The Court first addressed Exxon’s procedural argument. It held that the CTA did not commit reversible error in resolving the preliminary issue on whether Exxon was the proper party to seek a refund. The Court observed that the CIR prayed that the CTA resolve ahead of the other stipulated issues the question of Exxon’s standing, and that granting the motion would end the case if Exxon lacked standing.

The Court rejected the characterisation of the CIR’s motion as an untimely motion to dismiss. It relied on the controlling procedural provision in Rule 16, Section 6 of the 1997 Rules of Civil Procedure, which allows grounds for dismissal to be pleaded as affirmative defenses in the answer if no motion to dismiss was filed, with the court’s discretion to hold a preliminary hearing as if a motion to dismiss had been filed.

In the Court’s view, because the CIR did not file a motion to dismiss, it properly pleaded the dismissal grounds as affirmative defenses in the Answer. The issue on whether Exxon was the proper party was described as the “keystone” of the case; without standing, any further trial would be senseless. The Court also cited California and Hawaiian Sugar Company v. Pioneer Insurance and Surety Corporation to support the idea that where a preliminary hearing might settle the entire case, the trial court should not needlessly deny it and unnecessarily prolong proceedings.

Substantive Ruling: Whether Exxon Was the Proper Party to Claim a Refund

Having sustained the procedural resolution, the Court proceeded to the substantive question of whether Exxon, as the distributor and vendor who bore the economic burden after excise taxes were passed on, was entitled to a refund of excise taxes paid by Caltex and Petron.

The Court framed the controversy around the statutory scheme distinguishing between the party statutorily liable for the excise tax and the party who economically bears the burden. Exxon argued that it was the real party in interest because it paid the excise taxes as part of the purchase price, and that the exemption in Section 135 attaches to the petroleum products sold to international carriers for use outside the Philippines. It contended that Section 135 did not require that the exemption depend on whether the products were sold by the manufacturer or the distributor, and it insisted that legislative intent made Section 135 independent from Sections 129 and 130.

The CIR countered that Exxon was not the proper party because excise taxes on petroleum products are indirect taxes. The CIR maintained that Caltex and Petron, as sellers/manufacturers, were the persons statutorily liable to pay, even if Exxon bore the burden after the tax was passed as part of the purchase price. Thus, Exxon was not the taxpayer exempted or the taxpayer statutorily liable, and therefore it was not entitled to a refund.

The Court agreed with the CIR. It explained that excise taxes under the NIRC are imposed on specific goods manufactured or produced in the Philippines for domestic sales or consumption or other dispositions, and on imports, with exemptions such as those in Section 135 for petroleum products sold to international carriers and exempt entities or agencies. It quoted Section 135 and highlighted that petroleum products sold to international carriers are exempt from excise tax if stored in bonded storage tanks and disposed of only in accordance with rules and regulations upon recommendation of the Commissioner.

The Court then addressed the “confusion” resulting from the indirect character of excise taxes. It restated the doctrinal definition of indirect taxes from Commissioner of Internal Revenue v. Philippine Long Distance Telephone Company: these are taxes demanded in the first instance from one person but whose burden can be shifted to another, usually when the tax is imposed on goods before reaching the consumer. The Court emphasized the key doctrinal point: while the manufacturer or seller is the one statutorily liable for the tax, the buyer shoulders the economic burden as part of the price; nevertheless, the buyer does not thereby become the “taxpayer” for refund purposes.

Applying that doctrine, the Court cited the long-standing rule that the proper party to seek a refund of an indirect tax is the statutory taxpayer, meaning the person on whom the tax is imposed by law and who paid it. It traced this rule through cases such as Philippine Acetylene Co., Inc. v. Commissioner of Internal Revenue, Cebu Portland Cement Company v. Collector of Internal Revenue, and the reasoning in the Silkair decisions involving the purchase of jet fuel from Petron. In the Court’s account, Silkair (Singapore) Pte, Ltd. v. Commissioner of Internal Revenue held that Petron, not the airline, was the statutory taxpayer entitled to claim a refund under Section 135 and a relevant air transport agreement, ev
