G.R. No. L-31057 and L-31137. May 29, 1981.
INSULAR LUMBER COMPANY, petitioner, vs. COURT OF TAX APPEALS and COMMISSIONER OF INTERNAL REVENUE, respondents. COMMISSIONER OF INTERNAL REVENUE, petitioner, vs. COURT OF TAX APPEALS and INSULAR LUMBER COMPANY, respondents.

FACTS

Insular Lumber Company, a forest concessionaire, purchased manufactured oils and motor fuels in 1963 for use in its logging operations, sawmill, and other facilities, on which specific tax was paid. On December 22, 1964, the company filed a claim for a refund of P19,921.37, representing 25% of the specific tax paid, pursuant to Section 5 of Republic Act No. 1435. The Commissioner of Internal Revenue denied the claim, arguing that the five-year refund privilege for forest concessionaires under the law had lapsed on June 14, 1961. The company appealed to the Court of Tax Appeals.
The Court of Tax Appeals partially granted the claim but limited the refund. It ruled that the refund privilege applied only to oils used directly in logging operations, not in sawmill operations, reducing the claimable amount. It further held that the portion of the claim covering payments made from January 1 to April 29, 1963, had prescribed, as the claim was filed beyond the two-year period from payment. Thus, it ordered a refund of only P10,560.20. Both parties appealed to the Supreme Court.

ISSUE

The primary issues were: (1) whether Section 5 of R.A. 1435, granting a partial tax refund to forest concessionaires, is unconstitutional for allegedly embracing more than one subject not expressed in the title; (2) whether the refund privilege was limited to a period of five years from the law’s effectivity; (3) whether the refund applies to oils used in sawmill operations; and (4) whether part of the claim had prescribed.

RULING

The Supreme Court affirmed the decision of the Court of Tax Appeals. On constitutionality, the Court held that R.A. 1435 deals with a single subject—increasing the Highway Special Fund through specific taxes on oils. The proviso for a partial refund to miners and loggers is a legitimate exemption integral to this scheme and is not a separate subject. The title sufficiently apprised legislators of the law’s contents, and the records show it was fully debated in Congress. Every presumption favors the statute’s validity.
On the period of the refund, the Court ruled that the proviso granting the 25% refund contains no temporal limitation. The five-year period cited by the Commissioner refers to a different, unrelated proviso in the same section concerning the allocation of road funds. The refund privilege for forest concessionaires therefore remains effective as long as the specific tax is imposed. However, the claim is subject to the two-year prescriptive period for filing refund claims under the Tax Code. The Court upheld the Tax Court’s finding that claims for payments made from January to April 1963 were filed beyond this period, hence barred. Finally, the Court agreed that the sawmill operation is distinct from the logging concession, and the refund applies only to fuels used in the actual forest concession operations, not subsequent processing.
