The litigation that culminated in M.C.
Mehta v. Union of India (1998) 9 SCC SCC
381 began in 1985 when environmental lawyer M.C. Mehta filed a public interest
writ petition (Writ Petition (C) No. 4677 of 1985) under Article 32 of the
Constitution highlighting the severe air pollution in Delhi caused by nearly
1,68,000 hazardous and heavy industries (H-class industries such as foundries,
electroplating units, chemical units, and stone crushers) operating within the
municipal limits of Delhi in gross violation of the Delhi Master Plan 1962
(amended up to 1990) and the zonal plans that designated most of these areas as
residential.
Over the next decade, the Supreme Court
issued several interim orders directing the Delhi Administration and the
Central Government to identify non-conforming industries, stop their illegal
operation, and prepare schemes for their relocation. Despite repeated
directions and monitoring by a court-appointed committee, most industries
continued to function illegally without shifting, causing continued
deterioration of Delhi’s air quality. Finding non-compliance with its earlier
orders of 1995–1996, the Court finally posted the matter for final hearing in
1998 to decide the fate of these polluting industries operating in
non-conforming areas of Delhi, which led to the judgment reported in (1998) 9
SCC 381.
ISSUES:
The issues presented in M.C. Mehta v. Union
of India (1998) 9 SCC 381 centered on the persistent operation of hazardous and
heavy industries in non-conforming residential zones of Delhi, in violation of
the Delhi Master Plan 1962 and subsequent zonal plans, resulting in severe air
pollution and environmental hazards. The case addressed the non-compliance with
prior Supreme Court orders from 1995 and 1996 directing the identification,
closure, and relocation of approximately 168 polluting industries, as well as
the government's failure to implement relocation schemes, exacerbating public
health risks and urban degradation.
JUDGEMENT WITH REASONING:
The court's judgment directed the immediate
closure of all 168 identified hazardous industries operating in non-conforming
areas by November 30, 1998, with provisions for their relocation to designated
industrial estates outside Delhi, such as in neighboring states. It mandated
the allocation of industrial plots on a priority basis, compensation for
workers affected by closures, and the use of land vacated in Delhi for green
spaces or community use, while holding authorities accountable for enforcement.
The reasoning for the judgment was grounded
in the constitutional right to a clean and healthy environment under Article 21
of the Indian Constitution, which the court interpreted as encompassing the
right to pollution-free air. The bench noted that the unchecked proliferation
of polluting industries in residential areas had led to a public health crisis,
with air quality in Delhi deteriorating to dangerous levels due to emissions
from these units. Despite multiple interim orders over a decade, including the
formation of committees to monitor compliance, the Delhi Administration and
Central Government had failed to enforce the Master Plan's zoning regulations,
allowing industries to continue illegally. The court emphasized that
sustainable development must balance industrial growth with environmental
protection, and judicial intervention was necessary under the principle of
continuing mandamus to address executive inaction and ensure the enforcement of
environmental laws like the Environment (Protection) Act, 1986.
Furthermore, the court reasoned that while
relocation would impose economic burdens on industry owners and workers, the
greater public interest in safeguarding the health of millions of Delhi
residents outweighed these concerns. It highlighted the availability of
alternative sites in the National Capital Region and directed incentives such
as no-objection certificates for new locations, priority in power connections,
and financial assistance for relocation. The bench rejected arguments for
further delays, citing evidence from expert reports and affidavits showing
willful non-compliance by industries, and stressed that allowing such
violations to persist would undermine the rule of law and set a dangerous
precedent. The decision aimed to decongest Delhi, promote planned urban
development, and serve as a model for addressing similar environmental issues
in other cities.
ANALYSIS:
The 1998 Delhi Industrial Relocation
judgment marked a watershed moment in Indian environmental jurisprudence by
firmly establishing that the right to life under Article 21 includes the right
to live in a pollution-free environment, and that this right can prevail over
private economic interests and even the livelihood concerns of a limited number
of workers when weighed against the health of an entire city’s population. For
the first time, the Supreme Court treated large-scale violation of zoning laws
and the Master Plan as a continuing threat to fundamental rights, thereby
justifying drastic judicial intervention in the form of time-bound closure and
relocation of 168 hazardous industries. By rejecting repeated pleas for
extension of time and imposing personal accountability on government officers,
the Court sent a clear message that prolonged executive inaction or collusion
with violators would no longer be tolerated in matters affecting public health
and planned urban development.
Equally significant was the Court’s
pragmatic yet rights-centric approach to balancing development with
environmental protection. While acknowledging the hardship faced by industry
owners and approximately 50,000 workers, the bench adopted the principle of
sustainable development and prioritised the collective interest of millions of
Delhi residents over individual losses. It devised a comprehensive relocation
package (priority plot allotment, relaxed norms, workers’ compensation, and
conversion of vacated land into green belts or community facilities) that
softened the blow without diluting the core directive of closure. This judgment
not only decongested and de-polluted Delhi but also laid down a replicable
judicial template for tackling similar urban environmental crises across India,
reinforcing the use of continuing mandamus as an effective tool to compel
governmental compliance with environmental and planning laws.
