G.R. No. L-22480 October 4, 1971
Carlos Moran Sison and Priscila F. Sison, petitioners, vs. Commissioner of Internal Revenue, respondent.

FACTS

Petitioners Carlos and Priscila Sison sought reconsideration of the Supreme Court’s June 30, 1971 decision, which affirmed a Court of Tax Appeals (CTA) resolution. The CTA had denied the Sisons’ petition for a decision “on the merits” in their tax case and instead granted the Commissioner’s motion to execute a final Supreme Court judgment from a prior appeal (G.R. L-13739). The Sisons claimed the Supreme Court’s decision was based on a “misapprehension of facts,” specifically objecting to statements that they refrained from presenting evidence on the deficiency tax’s invalidity and that they argued the CTA was bound to set the case for a new hearing upon remand.
The Supreme Court acknowledged minor inaccuracies in its phrasing. The record showed the Sisons did present some evidence via Atty. Teodoro Dominguez and documents during a 1957 hearing. However, during that hearing, counsel indicated a preference to withhold further evidence pending a resolution on the preliminary issue of prescription. The Court clarified that the petitioners’ true contention was that upon remand, the CTA was obligated to decide the case on its merits, as the earlier CTA decision reversed by the Supreme Court had ruled solely on prescription without addressing the assessment’s validity.

ISSUE

Whether the alleged factual misapprehensions in the Supreme Court’s June 30, 1971 decision constitute reversible error justifying reconsideration and a remand for a decision on the merits of the tax assessment.

RULING

No. The motion for reconsideration is denied. The Court held that the noted inaccuracies were not reversible errors and did not affect the core legal logic of its decision. The ruling was fundamentally anchored on the interpretation of Section 14 of Republic Act No. 1125 , which governs the effect of decisions on prescription. The statute provides that if a court finds a tax claim barred by limitations, it is deemed a decision of no deficiency. Conversely, a finding that the claim is not barred must be understood as a decision that a deficiency exists.
In the prior case (G.R. L-13739), the Supreme Court reversed the CTA’s finding of prescription, thereby ruling the Commissioner’s claim for a P5,535.02 deficiency tax was not time-barred. The Court’s statement in that decision sustaining “the Collector’s actuation” constituted approval not only of the investigation process but also of its final result—the finding of tax liability. Consequently, the Supreme Court’s decision in G.R. L-13739 was a final adjudication on the merits regarding the existence of the deficiency. The CTA correctly understood this finality and properly ordered execution. A further trial on the merits was therefore superfluous. The probative value of the evidence cited by the Sisons was deemed irrelevant to this conclusive legal determination.
