G.R. Nos. L-41376-77, June 29, 1988
NORTHERN LINES INC., petitioner, vs. THE HON. COURT OF TAX APPEALS, COMMISSIONER OF CUSTOMS and COMMISSIONER OF INTERNAL REVENUE, respondents.

FACTS

Petitioner Northern Lines, Inc., a domestic shipping company, procured two vessels, the “Don Salvador” and “Don Amando,” from the Reparations Commission under contracts of Conditional Purchase and Sale in 1960. The Commissioner of Customs assessed compensating taxes on these vessels, which the Commissioner of Internal Revenue sustained. Petitioner challenged these assessments before the Court of Tax Appeals (CTA), but the CTA, in a 1971 joint decision, upheld the tax liability. This decision became final and executory after the Supreme Court denied petitioner’s appeal in 1972. Subsequently, the Commissioner of Internal Revenue demanded payment, leading the CTA to issue a writ of execution in 1974.
While execution was pending, petitioner and the Reparations Commission entered into a Memorandum of Agreement in February 1975 to restructure petitioner’s delinquent accounts, pursuant to Presidential Decree No. 332, which amended the Reparations Law. Relying on this agreement, petitioner filed a motion to quash the writ of execution, arguing it now qualified for a tax exemption under the amended Reparations Law. The CTA denied this motion, prompting the instant petition for review.

ISSUE

Whether the Memorandum of Agreement between petitioner and the Reparations Commission novated the final and executory judgment of the CTA, thereby entitling petitioner to an exemption from compensating tax and rendering the execution unjust.

RULING

The Supreme Court denied the petition and affirmed the CTA resolution. The legal logic is twofold. First, the theory of novation of judgment is inapplicable. For a compromise agreement to novate a final judgment, it must be executed by the actual party litigants. Here, the Memorandum of Agreement was between petitioner and the Reparations Commission, which was not a party to the tax case against the Commissioner of Customs and the Commissioner of Internal Revenue. The Reparations Commission is a distinct entity from the tax authorities who were the respondents seeking to collect the tax. Therefore, an agreement with a non-party cannot extinguish the obligations under a final judgment rendered against different parties.
Second, petitioner failed to prove a factual change in its situation that would warrant exemption and render execution inequitable. To claim the compensating tax exemption under the Reparations Law, as amended, petitioner needed a duly renovated utilization contract. The Reparations Commission had previously denied petitioner’s request for renovation. The subsequent Memorandum of Agreement was merely for restructuring delinquent accounts, not a renovation of the original procurement contract that would confer exempt status. Tax exemptions are construed strictly against the claimant, and the burden of proof rests on the party claiming it. Petitioner did not meet this burden, as it could not demonstrate a clear statutory right to exemption. Consequently, there was no legal barrier to the execution of the CTA’s final judgment ordering payment of the compensating tax. The State’s right to collect taxes, essential as the government’s lifeblood, must prevail absent a clear showing of exemption.
