Introduction:
The Supreme Court of India, in In Re: Regulation of Industries in the Taj Trapezium Zone v. SMW(C) No. 9/2026, delivered an important order balancing environmental protection with economic development by modifying its earlier restrictions on industrial activity in the Taj Trapezium Zone (TTZ). The matter was heard by a Bench comprising Chief Justice of India Surya Kant, Justice Joymalya Bagchi and Justice V. Mohana.
The case arose from the Court’s continuing supervision of environmental issues affecting the Taj Trapezium Zone, a protected region surrounding the Taj Mahal and several other heritage monuments. The TTZ was created to safeguard these monuments from industrial pollution, particularly emissions capable of causing deterioration to the marble structure of the Taj Mahal. The present proceedings are a continuation of the long-standing environmental litigation initiated in the celebrated M.C. Mehta cases, which have shaped India’s environmental jurisprudence for decades.
On October 14, 2024, the Supreme Court had directed that the TTZ Authority should not permit the establishment, expansion or relocation of any industry within the TTZ without obtaining prior approval from the Court. That direction was issued as an interim precaution because several significant environmental exercises remained incomplete, including the preparation of a comprehensive vision document for the region, a cumulative environmental impact assessment, and a final report identifying industries that could legitimately be classified as “non-polluting.”
Although the 2024 order was intended to prevent environmental degradation during this transitional period, its practical impact proved significant. Hundreds of industrial applications remained pending before the TTZ Authority. According to the authorities, most of these applications involved micro, small and medium enterprises (MSMEs), including small manufacturing units and service industries that neither relied upon coal nor produced substantial pollution. Consequently, the TTZ Authority approached the Supreme Court seeking relaxation of the earlier order so that pending applications could be processed.
The Court was therefore called upon to answer a difficult question. While environmental safeguards around one of the world’s most valuable cultural monuments could not be diluted, should legitimate economic activity remain indefinitely frozen merely because expert studies had not yet concluded? The decision reflects the Supreme Court’s attempt to reconcile two constitutional imperatives—environmental conservation under Articles 21, 48A and 51A(g), and the protection of livelihood and economic development.
Arguments of the Parties:
The Attorney General for India, R. Venkataramani, appearing for the TTZ Authority, submitted that the October 2024 order had unintentionally brought industrial development in the region to a standstill. He argued that numerous pending applications related to small-scale enterprises rather than large polluting industries. According to him, businesses such as flour mills, paper-product units and similar MSMEs were unable to commence operations or expand despite posing little environmental risk. He emphasized that the blanket requirement of obtaining prior approval from the Supreme Court for every application had effectively resulted in a regulatory deadlock.
The Attorney General argued that prolonged delays adversely affected employment, investment and local economic growth. He contended that the inability of authorities to process applications was causing genuine hardship to entrepreneurs and workers whose businesses depended upon timely regulatory approvals. He therefore urged the Court to evolve a practical mechanism that would preserve environmental safeguards without unnecessarily obstructing legitimate industrial activity.
Additional Solicitor General Aishwarya Bhati supplemented these submissions by pointing out that the TTZ extends across nearly 10,400 square kilometres and includes numerous towns and villages whose economic development cannot remain permanently suspended. She informed the Court that approximately 410 applications from MSMEs were pending before the TTZ Authority and clarified that none of the proposed industries intended to use coal or coke as fuel. According to her, the continued embargo disproportionately affected small entrepreneurs whose industries could not reasonably be described as major sources of pollution.
The ASG submitted that the blanket prohibition was frustrating the aspirations of millions residing within the TTZ region. She argued that while environmental protection remained essential, regulatory mechanisms should distinguish between genuinely polluting industries and enterprises that operate using clean technologies. The Government therefore requested the Court to permit the TTZ Authority to process applications under appropriate safeguards.
Senior Advocate Aparna Bhat, appearing for the applicant whose intervention had led to the October 2024 restrictions, opposed any broad relaxation of the Court’s earlier order. She contended that the TTZ Authority had previously failed to discharge its statutory responsibilities effectively, resulting in arbitrary approvals being granted to industries. According to her, it was precisely because of these deficiencies that judicial intervention had become necessary.
Bhat argued that the Court should remain cautious before restoring greater discretion to the Authority. She maintained that environmental regulation within the TTZ cannot be compromised merely because industries seek commercial expansion. Stressing the importance of the precautionary approach, she submitted that industrial permissions in such an ecologically sensitive region require rigorous scrutiny, transparency and accountability. In her view, attempts were being made to dilute environmental safeguards in the name of facilitating industrial growth.
During the hearing, the Attorney General questioned the applicant’s continued intervention and suggested that the proceedings were motivated by business rivalry rather than public interest. He remarked that the applicant should not “poke his nose” into matters concerning industrial regulation. Senior Advocate Bhat objected to this characterization and maintained that the applicant had approached the Court as a public-spirited individual genuinely concerned with protecting the environment. She denied that the litigation was driven by private commercial interests and emphasized that the earlier judicial intervention had exposed deficiencies in the functioning of the TTZ Authority.
Amicus Curiae Senior Advocate Liz Mathews also assisted the Court during the proceedings by addressing the practical challenges involved in balancing environmental protection with administrative efficiency. The Court considered submissions from all stakeholders before formulating a mechanism intended to safeguard both ecological interests and economic activity.
Court’s Judgment:
The Supreme Court acknowledged that its October 2024 order had served an important environmental purpose by ensuring that no fresh industrial permissions were granted until critical environmental studies were completed. However, the Bench observed that the prolonged pendency of these studies could not justify indefinitely freezing every industrial application, particularly where many applicants were MSMEs proposing activities that may ultimately qualify as non-polluting.
The Court observed that three significant initiatives remained incomplete: the preparation of a comprehensive vision document for the TTZ, the cumulative environmental impact assessment and the final determination regarding the classification of non-polluting industries. While recognizing the importance of completing these exercises within a time-bound framework, the Court concluded that their pendency should not become an obstacle to processing legitimate industrial applications.
The Bench emphasized that environmental governance should not operate through blanket prohibitions where an effective regulatory mechanism can achieve the same objective. Instead of requiring every application to be individually approved by the Supreme Court, the Court preferred to establish a robust institutional framework involving scientific experts and judicial oversight.
Accordingly, the Court modified its earlier order and permitted the TTZ Authority to process the approximately 410 pending applications. However, this permission was accompanied by stringent safeguards intended to ensure that environmental standards remain uncompromised.
The Court directed that every meeting of the TTZ Authority considering industrial applications must necessarily include one expert nominated by the Court-appointed Centrally Empowered Committee (CEC) and another expert nominated by the National Environmental Engineering Research Institute (NEERI). No meeting for considering industrial permissions can take place unless both experts are present.
The Court further held that if either of the two experts concludes that a proposed industry cannot properly be classified as a non-polluting industry, the application cannot be approved without obtaining leave from the Supreme Court. This effectively grants each expert an independent veto where environmental concerns arise.
Where both experts unanimously agree that an industry qualifies for approval and the TTZ Authority concurs with their opinion, the Authority may proceed to grant permission in accordance with law without approaching the Supreme Court for prior approval. This modification substantially reduces procedural delays while preserving expert scrutiny.
The Court also introduced an important transparency mechanism by directing that every decision approving an industry should be uploaded on the website of the Centrally Empowered Committee. This enables public-spirited individuals and environmental stakeholders to submit objections or suggestions. The TTZ Authority must consider these representations in consultation with the CEC and NEERI experts before finalizing its decision. By incorporating public participation into the decision-making process, the Court reinforced principles of transparency and environmental accountability.
Another significant safeguard concerns the role of the Amicus Curiae. Even where both experts unanimously support approval and the TTZ Authority agrees with them, every final decision must first be communicated to the Amicus Curiae. If the Amicus believes that a particular approval raises issues warranting judicial examination, an appropriate application may be moved before the Supreme Court. Thus, judicial oversight continues to exist even after expert concurrence.
The Court also directed the TTZ Authority to furnish complete material relating to every proposed industry to the CEC and NEERI experts sufficiently in advance of each meeting. This ensures that expert opinions are informed by comprehensive technical data rather than being rendered on incomplete records.
Importantly, the Bench clarified that this framework would apply not only to glass industries but also to all other industries seeking establishment, expansion or relocation within the TTZ. The arrangement shall remain operative until the cumulative environmental impact assessment is completed and the final determination regarding the definition of “non-polluting industries” is made.
The Court’s reasoning reflects the precautionary principle, one of the cornerstones of Indian environmental law. This principle requires authorities to anticipate and prevent environmental harm even where scientific certainty is incomplete. At the same time, the judgment demonstrates that precaution does not necessarily mandate an absolute prohibition on all economic activity. Rather, the Court held that careful scientific evaluation, independent expert participation and transparent decision-making can adequately protect environmental interests while allowing sustainable development.
The decision also reinforces the principle of sustainable development, which has consistently guided Indian environmental jurisprudence since the Supreme Court’s landmark decisions in M.C. Mehta v. Union of India, Vellore Citizens Welfare Forum v. Union of India, and A.P. Pollution Control Board v. Prof. M.V. Nayudu. These precedents recognize that environmental protection and economic progress are not mutually exclusive but must be harmonized through informed regulatory mechanisms.
By replacing an absolute judicial approval requirement with a structured expert-driven process, the Court sought to restore administrative efficiency without compromising environmental safeguards. The judgment reflects judicial confidence in scientific institutions while retaining sufficient supervisory powers to intervene whenever environmental concerns arise.
Ultimately, the Supreme Court struck a careful balance between preserving one of India’s most significant heritage ecosystems and ensuring that responsible industrial development is not unnecessarily stifled. The order demonstrates that environmental governance is most effective when scientific expertise, institutional accountability, public participation and judicial oversight function together rather than in isolation.
