Facts

  • The Ganga river suffered severe pollution from a combination of industrial effluent discharge and inadequate municipal sewage treatment along its course
  • M.C. Mehta filed a public interest litigation seeking comprehensive remediation
  • The scale and ongoing character of this pollution problem could not realistically be resolved through a single conventional order

Issue

  1. How to address severe, ongoing river pollution from combined industrial and municipal sources through sustained judicial intervention.

Held

  • The Supreme Court applied the constitutional environmental framework, drawing on Articles 48A, 51A(g), and the expanded Article 21
  • The Court retained continuing jurisdiction over the matter, adopting a continuing mandamus approach
  • Successive orders were issued over an extended period, addressing both industrial polluters and municipal sewage treatment infrastructure
  • Tanneries and other industrial polluters were directed to install effluent treatment, with closure as the consequence for non-compliance

Ratio decidendi

Courts may retain continuing jurisdiction over environmental matters, issuing successive orders and monitoring compliance over an extended period, where the scale and ongoing character of the pollution problem requires sustained oversight rather than a single conclusive judgment. Comprehensive river pollution remediation requires addressing both industrial and municipal contributing sources.

How to use it in an answer

  • Key line: "In M.C. Mehta v Union of India, the Ganga Pollution Case (1988), the Supreme Court developed the continuing mandamus technique, retaining ongoing jurisdiction over the river pollution crisis."
  • Pair with the Kanpur Tanneries Case as the specific remedial order within this broader litigation, and with the CNG Case as a later, parallel application of sustained judicial oversight to vehicular air pollution.
