Supreme Court of India (Shelat, J., delivering the judgment of the Court, with Bhargaya and Vaidialingam JJ.), August 5, 1968, in Civil Appeal No. 560 of 1966 by special leave against the award dated September 28, 1964 of the Industrial Tribunal, Bihar, in Reference No. 32 of 1963. The reference arose from a joint application dated September 7, 1963 under s. 10(2) of the Industrial Disputes Act, 1947 by the company and its 352 Jamshedpur-factory workmen represented by the Indoxco Labour Union; the notification of October 23, 1963 referred five disputes. HELD: (i) The award binds only the workmen of the Jamshedpur factory. The agreement and the statutory statement confined the disputes to those workmen, and nothing in the notification showed similar demands by other workmen; although the union purportedly amended its constitution on January 6, 1963 (renaming itself Indian Oxygen Workers Union and opening membership to workmen of all the company's Bihar establishments), it proved neither transmission of the amendments to the Registrar nor his registration as required by ss. 6(g), 28(3), 29 and 30(3) of the Trade Unions Act and regulation 9 of the Central Trade Union Regulation; the Tribunal's contrary conclusion was erroneous and the extension of the award to other establishments was without jurisdiction (The Associated Cement Companies Ltd. v. Their Workmen and Ramnagar Cane and Sugar Co. Ltd. v. Jatin Chakravorty, distinguished). (ii) Since the contractual working week was 39 hours, work beyond 39 hours is overtime attracting compensation; the Bihar Shops and Establishments Act (48-hour ceiling, double rate beyond 48 hours) does not govern the 39-48 hour band, and paying the ordinary rate there would give no extra compensation; the Tribunal's rate of 1½ times ordinary wages, fixed with regard to the company's higher wage scale and comparable Jamshedpur rates, was confirmed. (iii) The demand for special leave with pay for union executive committee, federation and INTUC meetings (demand No. 5) was disallowed: the existing concession for conciliation/tribunal attendance and the liberal leave roster sufficed, the obligation would be indefinite and productive of absenteeism, and such meetings can be held outside working hours or attended on earned leave (J. K. Cotton and Spinning and Weaving Mills v. Badri Mali, referred to on social justice in industrial adjudication). Appeal allowed in part; no order as to costs.
