Commissioner of Internal Revenue v. Republic Cement Corporation
REITERATIONFacts
The Antecedents: The Supreme Court previously ruled on August 10, 1983, that cement is a manufactured product, not a mineral product, and thus its sale is subject to sales tax under Section 186 of the Tax Code. The Court ordered private respondents to pay the 7% sales tax. Procedural History: Three separate Motions for Reconsideration were filed by the private respondents (Republic Cement et al., APO Cement et al., and CEPOC Industries, Inc.) challenging the August 10, 1983 decision. The Petition: The private respondents sought reconsideration of the decision, arguing that cement is a mineral product exempt from sales tax, that the new interpretation of the law should not be applied retroactively, and that the government's right to assess tax had prescribed.
Issue(s)
Whether cement is a mineral product exempt from sales tax. Whether the Supreme Court's interpretation of the taxability of cement can be applied retroactively. Whether the government's right to assess sales tax against CEPOC Industries, Inc. had prescribed.
Ruling
The Supreme Court denied all Motions for Reconsideration. The decision of August 10, 1983, was affirmed, and the private respondents were ordered to pay the 7% sales tax on the gross sales of cement. The tax liability of CEPOC Industries, Inc. was affirmed and clarified.
Ratio Decidendi
On the nature of cement: The Court reiterated its well-settled ruling that cement is a manufactured product, not a mineral product. This classification is crucial for determining its taxability. The Court noted that this issue had been consistently addressed in previous cases concerning the basis for computing the ad valorem mining tax. The legislative history of Republic Act No. 1299, which defined "mineral" and "mineral products," was considered, reinforcing the view that cement falls outside the exemption for mineral products. The Court explicitly overruled the case of Cebu Portland Cement Co. v. Collector of Internal Revenue (L-20563) insofar as it conflicted with the established doctrine that cement is a manufactured product subject to sales tax. On non-retroactivity: The Court clarified that its interpretation of the law, particularly that cement is not a mineral product under Section 246 of the Tax Code as amended by Republic Act No. 1299, constitutes part of the law as of the date of its amendment. This interpretation, established in prior cases, is not a new doctrine but a reiteration of the prevailing view. Therefore, the principle of non-retroactivity of new interpretations, as cited in Senarillos v. Hermosisima, et al., does not apply to shield the respondents from liability for sales tax on cement sold from the date of the amendment onwards. The Court distinguished this situation from cases where a doctrine is overruled and a new one adopted, emphasizing that the August 10, 1983 decision merely corrected an inconsistency with prior rulings and did not introduce a novel interpretation. On prescription: The Court clarified that for the five-year prescriptive period under Section 331 of the Tax Code to apply, the taxpayer must have filed the required sales tax return. The filing of returns for the ad valorem mining tax does not constitute substantial compliance for sales tax purposes. The Court agreed with the Commissioner of Internal Revenue that CEPOC Industries, Inc. had not filed the required sales tax returns for the period in question. Consequently, the statute of limitations did not begin to run. The assessment made in 1968 was therefore not barred by the five-year period. Even if the ten-year period for discovery of omission were considered, the assessment made in 1968 would still be within the prescriptive period, whether discovery was deemed to have occurred in 1960 (after filing ad valorem returns) or in 1967 (when the Commissioner changed his opinion following the first CEPOC case).
Main Doctrine
Cement is a manufactured product, not a mineral product, and is therefore subject to sales tax. The filing of ad valorem mining tax returns does not constitute substantial compliance for the purpose of starting the prescriptive period for sales tax assessments.
