The Court held that the incumbent President retained legislative power until the first Congress under the 1987 Constitution was convened, and that EO 273, issued on July 25, 1987, was a valid exercise of that authority. The governing principle is that a tax law satisfies the constitutional requirements of uniformity and equity if it operates equally on all persons similarly situated and its classifications are based on substantial distinctions germane to the purpose of the law.

Prior to EO 273, the Philippine sales tax system was a single-stage value-added tax imposed only on the original sale of goods by manufacturers, producers, or importers. Subsequent sales were generally untaxed, although Presidential Decrees in 1985 had introduced a reduced tax on second and subsequent sales. EO 273, issued on July 25, 1987, and effective January 1, 1988, amended the National Internal Revenue Code to expand and standardize the VAT at a rate of 10% on all sales of goods and services, unless zero-rated or exempt, thereby replacing the prior multi-tiered sales tax structure.

Executive Order No. 273 was signed by the President on July 25, 1987. The first Congress elected under the 1987 Constitution convened on July 27, 1987. The VAT under EO 273 imposed a 10% tax on the sale of goods and services by persons with aggregate gross annual sales exceeding P200,000.00, with specified exemptions and zero-rated transactions. Petitioners, including government employees' associations, labor centers, and a customs brokers' association, filed separate petitions alleging the VAT was oppressive, regressive, and unconstitutional, primarily contesting the President's authority to legislate at that time and the tax's alleged violation of uniformity and equity.

• Petitioners maintained that the President had no authority to issue EO 273 because the first Congress had already been "convened" when its members took their oaths of office on June 30, 1987, thus terminating the President's legislative power.
• They argued that the VAT is oppressive, discriminatory, unjust, and regressive, violating the constitutional mandate for a uniform, equitable, and progressive system of taxation.
• The Integrated Customs Brokers Association contended that the exception of customs brokers from the professional services exemption in Section 103(r) of the NIRC constituted undue discrimination.

• The Solicitor General argued that the petitions should be dismissed for lack of a justiciable controversy and for petitioners' lack of legal standing, as they were merely seeking an advisory opinion.
• He contended that the President validly exercised legislative power until Congress was formally convened on July 27, 1987.
• He asserted that EO 273 was the product of extensive study and a valid legislative process, not grave abuse of discretion, and that the VAT met constitutional standards of uniformity and equity.

• Procedural Issues: Whether the petitions presented a justiciable controversy and whether the petitioners had the requisite legal standing to sue.
• Substantive Issues:
  1. Whether the President had the constitutional authority to issue EO 273 on July 25, 1987.
  2. Whether EO 273 and the VAT it imposed violate the constitutional requirements that the rule of taxation be uniform and equitable (Article VI, Section 28[1]).

• Procedural: The Court acknowledged the procedural defects but invoked its duty to determine whether the other branches of government acted within constitutional limits. It brushed aside technicalities due to the public importance of the issues and took cognizance of the petitions.
• Substantive:
  1. On Legislative Authority: The Court ruled that under both the Provisional Constitution (Article II, Section 1) and the 1987 Constitution (Article XVIII, Section 6), the incumbent President was vested with legislative powers until the first Congress was "convened." It held that "convene" means the formal assembly of Congress as a body, not the individual members' assumption of office or oath-taking. Since Congress convened on July 27, 1987, EO 273 issued on July 25 was a valid exercise of legislative power.
  2. On Uniformity and Equity: The Court found the VAT to be uniform because it applies equally to all similarly situated sellers of goods and services at a constant rate. It is equitable because it exempts small businesses (with sales ≤ P200,000) and essential farm and marine products, thereby mitigating the burden on the public. The distinction of customs brokers from other professionals was based on a material difference—their activities partake more of a business than a profession—and thus did not constitute undue discrimination.

• Doctrine of Separation of Powers — The Court reiterated that it cannot substitute its judgment for that of the political branches on the wisdom, advisability, or justice of a law. Its role is limited to ensuring the law's enactment and content conform to constitutional limits.
• Standard for "Grave Abuse of Discretion" — The Court defined this as a capricious, whimsical, or arbitrary exercise of judgment so patent and gross as to amount to an evasion of positive duty. It found no such abuse in the issuance of EO 273.
• Requisites for a Valid Tax Classification (Uniformity and Equity) — A tax is uniform if it operates with the same force and effect on all persons similarly situated. The legislature may make reasonable classifications for taxation. A tax is equitable if its burdens are distributed fairly, considering the ability to pay and public benefit.

• "The Court has not power to re-write the Constitution and give it a meaning different from that intended." — Emphasizing the strict interpretation of the constitutional provision on the President's legislative power.
• "To justify the nullification of a law, there must be a clear and unequivocal breach of the Constitution, not a doubtful and argumentative implication." — Stating the high threshold for declaring a law unconstitutional.
• "The Court, following the time-honored doctrine of separation of powers, cannot substitute its judgment for that of the President as to the wisdom, justice and advisability of the adoption of the VAT." — Articulating the judiciary's deference to political branches on policy matters.

• City of Baguio v. De Leon — Cited for the definition of a uniform tax as one that applies equally to all persons, firms, and corporations in a similar situation.
• Philippine Trust Company v. Yatco — Referenced for the principle that a tax is uniform when it operates with the same force and effect wherever the subject may be found.
• Peralta v. Comelec — Invoked for the rule that a clear and unequivocal constitutional breach, not a doubtful implication, is required to nullify a statute.

• Article II, Section 1 of the Provisional Constitution (1986) — Vested sole legislative authority in the President until a legislature was elected and convened under a new Constitution.
• Article XVIII, Section 6 of the 1987 Constitution — Provided that the incumbent President shall continue to exercise legislative powers until the first Congress is convened.
• Article VI, Section 28(1) of the 1987 Constitution — Mandates that the rule of taxation shall be uniform and equitable, and that Congress shall evolve a progressive system of taxation.
• Sections 102 and 103(r) of the National Internal Revenue Code (as amended by EO 273) — Imposed VAT on the sale of services and exempted certain professional services, except those of customs brokers.
