Oil wells treated as plant and machinery, with treaty-based technical services and drilling costs allowed on the facts.

Oil wells used in mineral oil extraction were treated as plant and machinery for depreciation purposes, so the higher 60% rate applied to oil field equipment as well. Additional depreciation under section 32(1)(iia), foreign exchange gain treatment under section 43A, deduction under section 80IB(9), and depreciation on participating interest were remanded for verification or fresh adjudication. Technical service charges paid to the head office were held allowable because the services did not satisfy the make available condition under the India-US treaty. Preliminary drilling expenditure was treated as revenue expenditure, and disallowance for short deduction of tax under section 40(a)(ia) was held unsustainable.

Issues: (i) whether deduction under section 42 could be allowed; (ii) whether oil wells and oil field equipment were eligible for depreciation at 60% as plant and machinery and whether additional depreciation under section 32(1)(iia) was admissible; (iii) whether the foreign exchange gain adjustment under section 43A required fresh verification; (iv) whether deduction under section 80IB(9) in respect of the oil fields could be finally adjudicated; (v) whether technical service charges paid to the head office were allowable; (vi) whether preliminary drilling expenditure was revenue expenditure; (vii) whether disallowance under section 40(a)(ia) for short deduction of tax was sustainable; and (viii) whether depreciation on the amount paid for acquiring participating interest in a joint venture was to be restored for verification.

Issue (i): whether deduction under section 42 could be allowed.

Analysis: The claim under section 42 had already been negatived in earlier proceedings on the footing that the relevant product sharing contracts did not contain the contractual stipulation required for allowance under the provision. In view of that settled position, the same claim for the year in question could not succeed.

Conclusion: The issue was decided against the assessee.

Issue (ii): whether oil wells and oil field equipment were eligible for depreciation at 60% as plant and machinery and whether additional depreciation under section 32(1)(iia) was admissible.

Analysis: The Tribunal followed the jurisdictional High Court and its own earlier orders holding that oil wells form part of plant and machinery and not building. On that basis, oil field equipment used in field operations was also treated as eligible for the higher rate. For additional depreciation, the Tribunal accepted that extraction of mineral oil amounts to production of articles or things, but remitted the matter to the Assessing Officer to verify the statutory conditions before allowing the claim.

Conclusion: Depreciation at 60% on oil wells and oil field equipment was allowed in principle in favour of the assessee, while the claim for additional depreciation was restored for verification and was allowed for statistical purposes.

Issue (iii): whether the foreign exchange gain adjustment under section 43A required fresh verification.

Analysis: The Tribunal found that the record did not conclusively establish whether the gain was realised or unrealised. The character of the foreign exchange gain had to be verified before deciding whether any reduction from the block of assets was justified.

Conclusion: The issue was restored to the Assessing Officer for verification and was allowed for statistical purposes.

Issue (iv): whether deduction under section 80IB(9) in respect of the oil fields could be finally adjudicated.

Analysis: The Tribunal noted that the controversy on the retrospective effect of the relevant explanation and the status of each well as a separate undertaking was pending before the Supreme Court. In that situation, the Tribunal refrained from deciding the merits and remitted the matter for fresh adjudication in accordance with the eventual Supreme Court outcome.

Conclusion: The issue was not finally decided and was restored to the Assessing Officer for fresh adjudication.

Issue (v): whether technical service charges paid to the head office were allowable.

Analysis: The Tribunal held that the services did not satisfy the make available requirement under the India-US tax treaty and therefore did not constitute fee for included services. It further held that the expenditure was not hit by the head office expenditure restriction relied on by the revenue.

Conclusion: The issue was decided in favour of the assessee.

Issue (vi): whether preliminary drilling expenditure was revenue expenditure.

Analysis: The Tribunal accepted that the expenditure was incurred for feasibility and allied business operations, and that no capital asset of enduring nature had come into existence. The expenditure was therefore treated as revenue in nature.

Conclusion: The issue was decided in favour of the assessee.

Issue (vii): whether disallowance under section 40(a)(ia) for short deduction of tax was sustainable.

Analysis: The Tribunal followed the principle that where the grievance is only short deduction, the proper course is action under the default provisions governing tax deduction at source, not disallowance under section 40(a)(ia).

Conclusion: The issue was decided in favour of the assessee.

Issue (viii): whether depreciation on the amount paid for acquiring participating interest in a joint venture was to be restored for verification.

Analysis: The Tribunal found that the nature of the asset and the exact category under which depreciation was claimed had not been properly examined. It therefore directed the Assessing Officer to verify the supporting material and determine the admissibility in accordance with law.

Conclusion: The issue was restored to the Assessing Officer and was allowed for statistical purposes.

Final Conclusion: The appeals were disposed of with a mixed result: some claims were allowed on merits, some were remanded for verification or fresh adjudication, and the remaining claims were rejected.

Ratio Decidendi: Oil wells used in mineral oil extraction are to be treated as plant and machinery for depreciation purposes, and where treaty-based technical services do not satisfy the make available condition, the related expenditure is not disallowed on that footing.
