MUIR MILLS CO., LTD. vs SUTI MILLS MAZDOOR UNION, KANPUR.

The Supreme Court clarified the conditions under which a demand for bonus can be justified, specifically stating that it arises when (1) wages are below the living standard and (2) the industry reports substantial profits attributable to workers' contributions. The Court established that bonus is not a deferred wage and cannot be claimed in years of loss. Furthermore, it affirmed that Industrial Tribunals fall under the purview of Article 136 of the Constitution, allowing the Supreme Court to intervene in cases of arbitrary treatment or unfairness by these Tribunals.
