Motor engine replacement cost deemed revenue expenditure under Income-tax Act, 1961

The court held that the expenditure of Rs. 15,851 incurred by the assessee for replacing the motor engine is allowable as revenue expenditure under Section 31 of the Income-tax Act, 1961. The court determined that the replacement of the diesel engine constituted "current repairs," making the expenditure revenue in nature. The decision in R.B. Shreeram & Co. (P.) Ltd. v. CIT [1968] 67 ITR 428 was deemed incorrect, while the view in Hanuman Motor Service v. CIT [1967] 66 ITR 88 was upheld.

Issues Involved:
1. Conflict of judicial opinions on whether expenditure for replacing a motor engine is revenue or capital expenditure.
2. Whether the expenditure of Rs. 15,851 incurred by the assessee in replacing a motor engine is allowable as revenue expenditure under the Income-tax Act, 1961.

Detailed Analysis:

1. Conflict of Judicial Opinions:
The judgment notes a direct conflict between the view expressed by the Andhra Pradesh High Court in R.B. Shreeram & Co. (P.) Ltd. v. CIT [1968] 67 ITR 428 and the Mysore High Court in Hanuman Motor Service v. CIT [1967] 66 ITR 88. Other High Courts, such as Punjab and Haryana in CIT v. Khalsa Nirbhai Transport Co. (P.) Ltd. [1971] 82 ITR 741 and Gujarat in Addl. CIT v. Desai Bros. [1977] 108 ITR 14, have followed the Mysore High Court's view. The Madras High Court in CIT v. Sri Rama Sugar Mills Ltd. [1952] 21 ITR 191 also aligns with the Mysore High Court's perspective.

2. Allowability of Expenditure as Revenue Expenditure:
The core issue was whether the expenditure of Rs. 15,851 for replacing an old diesel engine with a new one in the assessee's motor van used for business purposes is allowable as revenue expenditure under the Income-tax Act, 1961.

Material Facts:
- The assessee, a firm in the beedi manufacturing and sale business, incurred Rs. 15,851 for replacing a diesel engine in its motor van.
- The Income Tax Officer (ITO) treated this expenditure as capital expenditure, disallowing it but permitting depreciation.
- The Appellate Assistant Commissioner (AAC) and the Income-tax Appellate Tribunal upheld the ITO's decision, prompting the reference to the High Court.

Legal Provisions Involved:
- Section 31: Allows deduction for repairs to machinery.
- Section 37(1): Allows deduction for any expenditure laid out wholly and exclusively for business purposes, provided it is not capital expenditure.

Arguments:
- Assessee's Argument: The expenditure should be considered under "repairs to machinery" (Section 31) or, alternatively, as revenue expenditure (Section 37(1)).
- Department's Argument: The expenditure is capital in nature and does not qualify under Section 31 or Section 37(1).

Court's Analysis:
- The court examined whether the engine of a motor vehicle qualifies as "machinery" under Section 31. Citing CIT v. Mir Mohammad Ali [1964] 53 ITR 165 (SC), it affirmed that a diesel engine is indeed "machinery".
- The court then considered whether replacing the engine constitutes "repair". Referring to Lurcott v. Wakely & Wheeler [1911] 1 KB 905, it distinguished "repair" from "renewal", noting that repair involves replacing defective parts, not the entirety.
- The court reviewed precedents, including:
- Rhodesia Railways Ltd. v. Income-tax Collector [1933] 1 ITR 227: Large-scale track renewal was deemed repair.
- CIT v. Mahalakshmi Textile Mills Ltd. [1967] 66 ITR 710 (SC): Significant expenditure for machinery conversion was considered current repair.
- Hanuman Motor Service v. CIT [1967] 66 ITR 88 (Mys): Replacing petrol engines with diesel engines in buses was deemed current repair.
- CIT v. Sri Rama Sugar Mills Ltd. [1952] 21 ITR 191 (Mad): Boiler replacement was treated as business expenditure.

Conclusion:
- The court concluded that the replacement of the diesel engine constituted "current repairs" under Section 31, making the expenditure revenue in nature, not capital.
- The decision in R.B. Shreeram & Co. (P.) Ltd. v. CIT [1968] 67 ITR 428 was deemed incorrect, while the view in Hanuman Motor Service v. CIT [1967] 66 ITR 88 was upheld.

Final Judgment:
The expenditure of Rs. 15,851 incurred by the assessee for replacing the motor engine is allowable as revenue expenditure under Section 31 of the Income-tax Act, 1961. The court's answer to the referred question was in the affirmative, favoring the assessee, with no order as to costs.
