Engine replacement as revenue expenditure and extra shift allowance on generators upheld under income-tax principles.

Replacement of a petrol engine with a diesel engine in a jeep was treated as revenue expenditure because it did not create a new asset; it only made the existing vehicle more economical and reduced running costs, forming part of the business profit-making process. Extra shift allowance on a generator was also held admissible despite the absence of a specific rule, following the Court's contemporaneous view on the issue. The reference was thus answered in favour of the assessee on the first question and in favour of the Revenue on the second, with no order as to costs.

Final Conclusion: The reference was disposed of by answering the first question for the assessee and the second question for the Revenue, with no order as to costs.
