UNION OF INDIA & ANR. A vs M.T.S.S.D. WORKERS UNION & ORS.

The Supreme Court upheld the Bombay High Court's decision that the division of constituencies for the election of the Works Committee under the Industrial Disputes (Central) Rules, 1957 was impermissible when a registered trade union has more than 50% membership. The Court clarified that under Rule 42, if a trade union represents more than half the workers, elections must be conducted without constituency division. The appeal was dismissed, affirming the High Court's interpretation of Rules 39, 41, 42, and 43 of the Industrial Disputes Act, 1947.
