Case Note & Summary
The case involved an appeal by M/s South India Viscose Ltd. against the Commissioner of Income Tax concerning the computation of depreciation by way of extra shift allowance for the assessment year 1971-72. The Income Tax Appellate Tribunal had referred four questions to the Madras High Court, with three answered in favor of the assessee and one against. The disputed question pertained to the entitlement of extra shift allowance for machinery added during the relevant previous year based on the entire concern's operation rather than individual machinery usage. The assessee, a public limited company engaged in manufacturing rayon yarn and wood pulp, claimed multiple shift allowance based on the overall operation of the concern. The Income Tax Officer restricted the allowance to the number of days each machinery operated. The Appellate Assistant Commissioner and the Tribunal supported the assessee's claim, but the High Court ruled against it, requiring individual machinery assessment. The Supreme Court analyzed the provisions of Rule 5 and Appendix I of the Income Tax Rules, 1962, and Section 32 of the Income Tax Act, 1961, concluding that the extra shift allowance should be based on the entire concern's operation. The court emphasized that the High Court's interpretation was flawed as it necessitated an examination of each machinery's usage, which was not required by the statutory provisions. The Supreme Court allowed the appeal, set aside the High Court's judgment regarding question No. 4, and ruled in favor of the assessee, affirming that the extra shift allowance should be calculated based on the number of days the entire concern worked double or triple shifts.
