Commissioner of Internal Revenue vs. Philippine Power and Development Co., Inc.

The Court held that pending tax appeals are rendered moot and academic when the parties fully settle the underlying deficiency assessment and extinguish the liability through the application of valid tax credits. Because the subject matter of the controversy was completely satisfied outside the appellate process, the Court dismissed the cases without costs.

The Court of Tax Appeals rendered a decision on October 31, 1965, in CTA Case No. 1152, modifying a deficiency franchise tax assessment against Philippine Power and Development Co., Inc. (PPDC) for the period covering October 1, 1955 to June 30, 1960. The CTA ordered PPDC to pay ₱138,175.52 within thirty days from finality, subject to a twenty-five percent delinquency surcharge under Section 259 of the Revenue Code for failure to pay within the prescribed period. Both the Commissioner of Internal Revenue (CIR) and PPDC filed separate appeals to the Supreme Court to contest the modified assessment and the tax liability computation.

• The CIR assessed PPDC for deficiency franchise tax covering October 1, 1955 to June 30, 1960.
• The CTA modified the assessment and ordered PPDC to pay ₱138,175.52, subject to a 25% delinquency surcharge under Section 259 of the Revenue Code if unpaid within thirty days of finality.
• Both the CIR and PPDC appealed the CTA decision to the Supreme Court, raising separate challenges to the liability computation and assessment validity.
• During the pendency of the appeals, PPDC availed of the tax settlement privileges under Letter of Instructions No. 308.
• The CIR accepted PPDC’s offer to settle 30% of the adjudicated deficiency amount of ₱133,175.52, resulting in a final settlement figure of ₱33,952.66.
• PPDC applied an existing tax credit of ₱79,229.06 against the ₱33,952.66 liability, fully covering the assessed amount.
• The CIR issued a Tax Debit Memo dated January 17, 1977, acknowledging the application of the tax credit and the extinguishment of the deficiency liability.
• The parties jointly moved to dismiss the pending appeals, asserting that the settlement and credit application rendered the cases moot and academic.

• Petitioner CIR maintained that the pending appeal should be dismissed because PPDC’s voluntary settlement under LOI No. 308 and the application of its tax credits fully satisfied the deficiency franchise tax liability.
• Petitioner CIR and PPDC jointly argued that the extinction of the tax obligation through administrative settlement and credit application removed any live controversy, thereby rendering the appeals moot and academic.
• Petitioner PPDC concurred with the joint manifestation, emphasizing that the Tax Debit Memo confirmed the complete settlement of the assessed deficiency, leaving no basis for continued appellate review.

• N/A (The designated respondent, the Court of Tax Appeals, was a nominal party to the administrative appeal, and the substantive respondent, the CIR, joined the petitioner in the joint motion. Both active parties concurred in the prayer for dismissal.)

• Procedural Issues: Whether the pending appeals before the Supreme Court should be dismissed as moot and academic following the parties’ administrative settlement and extinguishment of the tax liability.
• Substantive Issues: N/A

• Procedural: The Court granted the joint motion and dismissed G.R. Nos. L-25501 and L-25507 without costs. Because the taxpayer fully settled the deficiency franchise tax liability pursuant to LOI No. 308 and applied a sufficient tax credit to cover the adjudicated amount, the subject matter of the controversy was completely extinguished. Consequently, the appeals became moot and academic, warranting immediate dismissal.
• Substantive: N/A

• Mootness Doctrine — An appeal ceases to present a justiciable controversy when the underlying dispute has been resolved or the subject matter has been fully satisfied, rendering further judicial determination unnecessary. The Court applied this doctrine after finding that the taxpayer’s administrative settlement and tax credit application completely extinguished the deficiency franchise tax liability, thereby eliminating any live controversy for appellate resolution.

• "as the herein appeals have become moot and as prayed for by the parties, the cases at bar are dismissed without costs." — The Court’s dispositive ruling directly reflects the application of the mootness doctrine, confirming that voluntary settlement and full satisfaction of the tax obligation terminate the necessity for appellate adjudication.

• Section 259 of the Revenue Code — Cited by the CTA as the statutory basis for imposing a twenty-five percent delinquency surcharge on unpaid deficiency taxes within the prescribed thirty-day period.
• Letter of Instructions No. 308 — Cited as the executive directive authorizing the taxpayer to avail of tax settlement privileges, which formed the administrative basis for the 30% compromise payment that extinguished the deficiency liability.
