Provisional assessment cannot finally decide disputed rebate eligibility; mixed questions of fact and law must await regular assessment

A provisional assessment under section 141 must be made on the basis of the return and accompanying material, and the Income-tax Officer cannot finally decide a disputed mixed question of fact and law at that stage. The note states that the officer may apply settled law to admitted facts, but cannot conduct a conclusive factual inquiry without regular assessment proceedings. It also records that, on the material then available, a company refining crude oil could prima facie fall within the expression "manufacture or production of mineral oil" for rebate purposes, so the contrary view could not be treated as established provisionally. The provisional assessment and demand were therefore set aside.

Issues: (i) Whether a company engaged in refining crude oil could, on the material then available, be treated as engaged in the manufacture or production of mineral oil for purposes of rebate under the Finance Act, 1965; (ii) Whether the Income-tax Officer could, in a provisional assessment under section 141 of the Income-tax Act, 1961, decide that disputed question against the assessee instead of proceeding on the basis of the return in a summary manner.

Issue (i): Whether a company engaged in refining crude oil could, on the material then available, be treated as engaged in the manufacture or production of mineral oil for purposes of rebate under the Finance Act, 1965.

Analysis: The rebate structure under the Finance Act, 1965 depended on whether the company's income was attributable to the business of manufacture or production of mineral oil. The expression "mineral oil" was held to be wide enough, on the dictionary and contextual material referred to, to include crude petroleum and products obtained by refining. The nature of the assessee's business, the meaning of the expression, and the exact nature of the products resulting from the refining process involved a contested factual and legal inquiry.

Conclusion: The assessee prima facie appeared to fall within the description of a company engaged in the manufacture or production of mineral oil, and the contrary position could not be said to be conclusively established at the provisional stage.

Issue (ii): Whether the Income-tax Officer could, in a provisional assessment under section 141 of the Income-tax Act, 1961, decide that disputed question against the assessee instead of proceeding on the basis of the return in a summary manner.

Analysis: Section 141 required a provisional assessment to be made on the basis of the return and accompanying material, in a summary manner, and without prejudging issues reserved for regular assessment. A disputed mixed question of fact and law, requiring inquiry and evidence, could not properly be finally decided ex parte at the provisional stage. The officer could apply the law to admitted facts, but could not embark upon a full factual determination where the assessee had no opportunity to lead evidence and the issue remained controversial.

Conclusion: The Income-tax Officer acted in excess of jurisdiction in denying the higher rebate at the provisional assessment stage by deciding the disputed issue against the assessee.

Final Conclusion: The provisional assessment and demand were set aside because the disputed rebate issue had to be left open for determination in regular assessment proceedings.

Ratio Decidendi: In a provisional assessment under section 141 of the Income-tax Act, 1961, the Income-tax Officer must proceed on the basis of the return and cannot conclusively decide a disputed mixed question of fact and law requiring inquiry, which is reserved for regular assessment.
