Landmark Principles
Urban Air Quality (Directions in 1991, 1996 and 2019 in WP 13029 of 1985)
The case of M.C. Mehta v. Union of India, Writ Petition (Civil) No. 13029 of 1985, is a landmark judgment by the Supreme Court of India that significantly advanced environmental jurisprudence in the country. Initiated by environmental lawyer M.C. Mehta, the petition addressed the severe air pollution in Delhi caused by vehicular emissions.
Background:
In the mid-1980s, Delhi faced escalating air pollution levels, primarily due to the increasing number of vehicles emitting harmful pollutants. M.C. Mehta filed a public interest litigation seeking the Court’s intervention to mitigate this environmental hazard.
Key Directives Issued by the Supreme Court:
- 1986: In this ruling, the Supreme Court reiterated the principle of absolute liability for industries engaged in hazardous activities, building on the earlier discussions from 1986. The court emphasized that such industries must ensure that no harm comes to the public, regardless of the precautions taken. This case established that industries cannot escape liability by claiming they followed all safety protocols if an accident occurs. (Judgement dated 20-12-1986, See https://indiankanoon.org/doc/1486949/).
- 1991: The Supreme Court established a committee to tackle vehicular pollution in Delhi, comprising a retired judge, M.C. Mehta, the Chairman of the Central Pollution Control Board, and representatives from the automobile industry.[https://indiankanoon.org/doc/1488667/]
- 1995 CNG Case: The Supreme Court addressed the issue of vehicular pollution in Delhi, reinforcing the need for stringent regulations on emissions from vehicles.
