High Court of Karnataka (Anant Ramanath Hegde J, 04.03.2025) allowed W.P. No.19984/2014 (L-RES) by the management of BEML Ltd (formerly Bharat Earth Movers Ltd) against the award dated 11.09.2013 in I.D. No.69/2007 of the Industrial Tribunal, Bangalore, which had declared illegal the establishment's notice dated 21.07.2006 under Section 9A of the Industrial Disputes Act, 1947 reverting the divisor for computing vacation-leave (leave encashment) wages from 26 back to 30. Held: (1) Section 9A itself does not prescribe the mode of service; the manner of giving notice is governed by Rule 35, Industrial Disputes (Karnataka) Rules, 1957 and Form E. Where a proposed change affects ALL workmen of an establishment having a registered Union or Association, Section 9A read with Rule 35 does not require individual notice to each workman: conspicuous display of the notice at the main entrance and in the Manager's office, plus registered-post service of a copy on the Union Secretary, constitutes valid notice — the 12.08.1960 omission of old Rule 36 (which had contemplated personal service in certain situations) confirms this construction; whether individual notice is required when a change affects only some or few workmen was expressly left open. (2) The 'employer' named or defined in the certified Standing Orders (clause 2.3, including the Deputy General Manager when authorised) can issue the Section 9A notice, the Standing Orders' employer-definition being readable into Section 9A in appropriate cases; the Tribunal's insistence that only the Board of Directors could decide was erroneous — the coordinate-bench decision in W.P. No.8743/2006 C/W W.P. No.8653/2006 rested on an admission absent here and ignored the Standing Orders. (3) Origin of the change in a Comptroller of Audit report does not vitiate it, and the Payment of Gratuity Act, 1972 'working days' analogy is inapplicable to vacation-leave computation. Babu Verghese (AIR 1999 SC 1281(1)) held inapplicable; Syed Yakoob (AIR 1964 SC 477) relied on; Suresh Chandra Singh ((2004) 1 SCC 59) invoked on PSU autonomy. Award set aside; notice held valid; reference answered in favour of the establishment.
