Voltas Limited v. Its Workmen (Supreme Court of India, December 9, 1960; Gajendragadkar, Wanchoo and Das Gupta JJ.; judgment by Wanchoo J.), Civil Appeals Nos. 153 and 154 of 1960 — appeals by special leave from the award dated February 5, 1959 of the Industrial Tribunal, Bombay in Reference (I.T.) No. 212 of 1958 on the quantum of bonus for 1956-57. Held: (i) a donation of rupees one lakh to a political fund, though permitted by the company's law or rules, is in effect charity and not a proper expense deductible in working out available surplus under the Full Bench formula; (ii) neither the insurance rebate earned under principal agency, nor gains on foreign exchange transactions in the normal course of business, nor commission on transactions entered directly with foreign manufacturers where the workmen serviced the goods, is extraneous income — a claim of extraneous character must be proved to the tribunal's satisfaction, and failing evidence the amount is taken into account; (iii) no higher return than 6% on capital and 4% on working capital absent special reason; (iv) extra income-tax of Rs. 4.4 lakhs due to a mid-year rate increase rightly allowed; (v) no fresh prior charge (gratuity provision of Rs. 4.76 lakhs) can be added to the Full Bench formula, such matters being considered at the distribution stage; (vi) salesmen paid commission have already shared profits on a fair basis and get no further bonus; apprentices, who hardly contribute to profits and are excluded by contract, get no bonus. The Tribunal's award of five months' basic wages as bonus (Rs. 16.80 lakhs; available surplus Rs. 30.13 lakhs) upheld; both appeals dismissed, no order as to costs.
