Separate industrial undertaking, crystallised pension liability and cess deductibility under section 43B shaped the tax outcome.

A clinker-producing vertical shaft kiln was treated as a separate industrial undertaking because it used distinct machinery and a separate dry process, and it produced marketable clinker even though the output was captively consumed; deduction under section 80-I, and consequentially section 80HH, was allowed. Actuarially valued pension liability was deductible once the amended scheme crystallised the employer's obligation, including the amount relating to prior years brought into account on amendment. Commuted pension retained its character as pension for section 40A(5) and was subject to the ceiling for payments to former employees, with disallowance limited accordingly. Cess on royalty was held outside the pre-amendment scope of section 43B for the relevant year, so deduction was allowed.

Issues: (i) Whether the clinker-producing vertical shaft kiln plant constituted a separate industrial undertaking eligible for deduction under section 80-I and, consequentially, under section 80HH; (ii) whether the actuarially valued pension liability, including amounts relating to prior years, was allowable as a deduction; (iii) whether commuted pension payments to retired employees were to be included in the disallowance under section 40A(5); (iv) whether cess on royalty was deductible under section 43B.

Issue (i): Whether the clinker-producing vertical shaft kiln plant constituted a separate industrial undertaking eligible for deduction under section 80-I and, consequentially, under section 80HH.

Analysis: The plant employed a distinct dry process, separate machinery, silos and conveyor system, and produced clinker as a marketable commodity. The fact that clinker was later used captively in cement manufacture did not destroy its character as an identifiable product or as the output of a physically separate and viable unit. The investment test was not decisive once the unit was found to be separate and distinct in substance.

Conclusion: The claim under section 80-I was allowed, and the claim under section 80HH followed on the same reasoning, in favour of the assessee.

Issue (ii): Whether the actuarially valued pension liability, including amounts relating to prior years, was allowable as a deduction.

Analysis: The amended pension scheme withdrew the earlier absolute discretion to alter or withdraw accrued benefits retrospectively. By the end of the accounting year, the employees' rights had crystallised and the liability had become ascertained. The accounting provision was not merely contingent, and the later amendment justified deduction of both the current year's actuarial liability and the accumulated earlier liability brought into account in the year of amendment.

Conclusion: The deduction was admissible, in favour of the assessee.

Issue (iii): Whether commuted pension payments to retired employees were to be included in the disallowance under section 40A(5).

Analysis: Commuted pension retained the character of pension notwithstanding its lump-sum form. For the purpose of section 40A(5), it had to be treated as a payment to former employees, attracting the separate monetary ceiling applicable to such payments. Only the balance beyond the permissible limit could be considered for disallowance.

Conclusion: The departmental objection succeeded only partly, and the matter was decided partly in favour of the Revenue and partly in favour of the assessee.

Issue (iv): Whether cess on royalty was deductible under section 43B.

Analysis: Although the levy had been treated as valid and constitutionally supportable for the period in question, the expression "tax" in section 43B was used in a narrower statutory sense and did not, at the relevant time, include cess. The later amendment inserting cess and fee was prospective and could not govern the assessment year involved.

Conclusion: The cess was not hit by section 43B for the assessment year concerned, in favour of the assessee.

Final Conclusion: The appeals were disposed of by sustaining the assessee's principal claims on industrial undertaking deduction, pension liability and cess deduction, while granting only partial relief to the Revenue on the commuted pension issue.

Ratio Decidendi: A unit is a separate industrial undertaking if it is physically distinct, viable on its own and produces a marketable intermediate product; a liability becomes deductible when the scheme crystallises the obligation; commuted pension remains pension for section 40A(5) but must be examined under the ceiling for former employees; and cess was outside the narrower pre-amendment scope of section 43B.
