On 18 September 1982, a two-judge bench held that payment below minimum wage is 'forced labour' under Article 23, opening Article 32 to construction workers at the Delhi Asian Games sites.
On 18 December 1997 a three-judge bench of the Supreme Court led by Chief Justice J.S. Verma, hearing the Jain hawala public interest litigation, issued a set of structural directions to insulate the Central Bureau of Investigation and the Enforcement Directorate from executive interference. The judgment fixed a two-year tenure for the CBI Director, gave the Central Vigilance Commission statutory status, struck down the 'Single Directive', and operationalised continuing mandamus as a tool of monitored investigation. It is the foundational case in modern Indian PIL practice.
