Commissioner of Internal Revenue vs. Lingayen Gulf Electric Power Co., Inc.

The Court held that a legislative franchise containing a specific retroactivity clause prevails over the general franchise tax rate in the National Internal Revenue Code. Because R.A. No. 3843 expressly provided that its 2% tax rate, in lieu of all other taxes, was effective from the date the original franchise was granted, it extinguished any liability for the higher 5% tax for periods after that date. The Court also ruled that the law's differential tax rate did not violate the constitutional uniformity rule, as the legislature has the power to classify subjects of taxation and grant exemptions.

Lingayen Gulf Electric Power Co., Inc. operated an electric power plant under municipal franchises granted in 1946 by the municipalities of Lingayen and Binmaley, Pangasinan. These franchises, approved by the President in 1948, stipulated a franchise tax of 1-2% of gross earnings. The Bureau of Internal Revenue later assessed deficiency franchise taxes against the company for the years 1946-1954 and 1959-1961, applying the 5% rate prescribed by Section 259 of the National Internal Revenue Code. In 1963, while the tax cases were pending, Congress enacted R.A. No. 3843, granting the company a new legislative franchise that imposed a 2% franchise tax on gross receipts, expressly in lieu of all other taxes and made retroactive to the date of the original franchise.

Lingayen Gulf Electric Power Co., Inc. operated under municipal franchises granted in 1946 and approved by the President on February 24, 1948. The franchises provided for a tax of 1-2% of gross earnings. The BIR assessed deficiency taxes for 1946-1954 and 1959-1961, applying the 5% rate from Sec. 259 of the Tax Code. The company protested, arguing overpayment. During the pendency of the appeals, R.A. No. 3843 was enacted on June 22, 1963, granting a new legislative franchise. Its Section 4 imposed a 2% tax on gross receipts, "in lieu of any and all taxes," and stated this was "effective further upon the date the original franchise was granted." The CTA dismissed the assessments based on this law. The Commissioner appealed, challenging the law's constitutionality and retroactivity.

• Petitioner Commissioner of Internal Revenue argued that the 5% franchise tax under Sec. 259 of the Tax Code applied to the respondent's gross receipts, as it governed existing and future franchises.
• Petitioner contended that Sec. 4 of R.A. No. 3843 was unconstitutional for violating the uniformity and equality of taxation clause, as it imposed a 2% rate on the respondent while other similarly situated taxpayers paid 5%.
• Petitioner asserted that even if valid, R.A. No. 3843 should not be applied retroactively to defeat tax liabilities that accrued and were assessed prior to its enactment.
• Petitioner claimed the respondent was liable for fixed and deficiency percentage taxes for the period January 1, 1946 to February 29, 1948, before the original franchise was approved.

• Respondent Lingayen Gulf Electric Power Co., Inc. argued that its liability was governed by the terms of its franchise, which had been superseded by R.A. No. 3843.
• Respondent maintained that R.A. No. 3843's specific tax exemption and retroactivity clause controlled, limiting its tax liability to 2% of gross receipts from the date of the original franchise.
• Respondent contended that the legislative classification for taxation purposes was valid and did not violate the uniformity rule.
• Respondent asserted that it had already paid taxes in excess of what was rightfully due over the entire period in question.

• Procedural Issues: N/A
• Substantive Issues:
  • Whether the 5% franchise tax under Sec. 259 of the National Internal Revenue Code was collectible for receipts realized before the effectivity of R.A. No. 3843.
  • Whether Sec. 4 of R.A. No. 3843 is unconstitutional for violating the uniformity and equality of taxation clause.
  • If valid, whether R.A. No. 3843 could be given retroactive effect to render uncollectible taxes assessed before its enactment.
  • Whether the respondent was liable for fixed and deficiency percentage taxes for the period prior to the approval of its original municipal franchise (Jan. 1, 1946 to Feb. 29, 1948).

• Procedural: N/A
• Substantive:
  • The Court ruled that the 5% tax was not collectible. R.A. No. 3843, a subsequent legislative franchise, expressly provided for a 2% tax "in lieu of any and all taxes" and made this effective from the date the original franchise was granted. This specific law superseded the general tax code provision.
  • The Court upheld the constitutionality of R.A. No. 3843. It found no violation of the uniformity rule, stating that the legislature has the power to select subjects of taxation and grant exemptions. The law merely transferred the respondent's power plant to a different class of franchise holders (those under Act No. 3636, as amended) entitled to a 2% rate.
  • The Court held that R.A. No. 3843 applied retroactively. The law's text explicitly stated it was "effective ... upon the date the original franchise was granted," demonstrating clear legislative intent for retroactive application.
  • The Court found the respondent not liable for the pre-franchise period deficiency tax. While the exemption in R.A. No. 3843 did not cover the period before February 24, 1948, the CTA's finding that the respondent had paid more than the total amount due over the entire period (1946-1961) was sustained. Thus, no further payment was warranted.

• Legislative Power to Grant Tax Exemptions and Classify — The Legislature has the inherent power not only to select the subjects of taxation but to grant exemptions. Tax exemptions, when granted through a valid legislative classification, do not violate the constitutional guarantee of equal protection or uniformity in taxation. The Court applied this by ruling that R.A. No. 3843 created a valid class for taxation purposes.
• Supremacy of a Special Legislative Charter over General Law — A special charter or franchise enacted by the Legislature is in the nature of a private contract and prevails over general statutory provisions. The Court relied on this to hold that the specific tax provisions of R.A. No. 3843 controlled over the general 5% rate in the Tax Code.
• Retroactive Application of Statutes Based on Legislative Intent — Whether a statute operates retrospectively depends on the legislative intent. A clear expression in the law itself, such as an effective date prior to its enactment, demonstrates intent for retroactive application. The Court applied this to validate the retroactive effect of R.A. No. 3843.

• "A tax is uniform when it operates with the same force and effect in every place where the subject of it is found. Uniformity means that all property belonging to the same class shall be taxed alike. The Legislature has the inherent power not only to select the subjects of taxation but to grant exemptions. Tax exemptions have never been deemed violative of the equal protection clause." — This passage states the core constitutional principle applied to reject the uniformity challenge.
• "Charters or special laws granted and enacted by the Legislature are in the nature of private contracts. They do not constitute a part of the machinery of the general government. They are usually adopted after careful consideration of the private rights in relation with resultant benefits to the State..." — This quote justifies the primacy of the special legislative franchise (R.A. No. 3843) over the general tax code.

• Philippine Railway Co. v. Collector of Internal Revenue, 91 Phil. 35 — Cited for the proposition that the 5% franchise tax rate in the Tax Code was not intended to have universal application, as the law itself allows for lower rates when a franchise charter precludes a higher tax.
• Visayan Electric Co. v. David, 92 Phil. 969 — Cited alongside the Philippine Railway Co. case for the same principle regarding the non-universal application of the 5% rate.
• Manila Railroad Co. v. David, 40 Phil. 224 — Cited for the principle that special legislative charters are adopted after careful consideration of specific circumstances and are akin to private contracts.
• Gomez v. Palomar, 25 SCRA 827 — Cited for the definition of uniformity in taxation and the legislature's power to grant exemptions.

• Section 259 of the National Internal Revenue Code (C.A. 466, as amended by R.A. 39) — Imposed a 5% franchise tax on grantees of franchises. The Court ruled it was superseded by the specific rate in R.A. No. 3843.
• Section 4 of Republic Act No. 3843 — The legislative franchise provision imposing a 2% franchise tax on gross receipts "in lieu of any and all taxes," made effective from the date the original franchise was granted. This was the central provision applied by the Court.
• "Uniformity and equality of taxation" clause of the 1935 Constitution — The constitutional provision invoked by the petitioner to challenge R.A. No. 3843. The Court found no violation.
