On 6 March 1973, a two-judge bench of the Supreme Court gave Section 11A its foundational construction — the Industrial Tribunal's own satisfaction on guilt and punishment displaces the four-grounds restraint of Indian Iron & Steel, and the Tribunal may alter the punishment imposed by an employer.
On 27 January 2026, a two-judge bench of Justices Pankaj Mithal and S.V.N. Bhatti held that disputes relating to the employment, termination, or alleged sham nature of contract labour arrangements must be adjudicated by a Labour Court or Industrial Tribunal under the Industrial Disputes Act, 1947 — and that the State's reference jurisdiction operates even on an apprehended dispute and is not foreclosed by the absence of a prior written demand on the employer. The judgment reaffirms the SAIL safeguards for contract labour and supplies a working architecture for contract-labour litigation.
