Bombay High Court Establishes High Power Committee to Combat Persistent Air Pollution in Mumbai

Introduction

In a significant move to address the escalating air pollution crisis in Mumbai and the Mumbai Metropolitan Region (MMR), the Bombay High Court has constituted a High Power Committee (HPC) comprising two retired judges to oversee compliance with its directives and recommend comprehensive measures for pollution control. The division bench, led by Chief Justice Shree Chandrashekhar and Justice Gautam A. Ankhad, took this step in a suo motu public interest litigation (PIL) initiated in October 2023, highlighting the "lackadaisical approach" of civic authorities despite repeated court orders. The HPC, headed by former Chief Justice of the Himachal Pradesh High Court Amjad A. Sayed and former Bombay High Court Judge Anuja Prabhudessai, will monitor reports from key bodies like the Brihanmumbai Municipal Corporation (BMC), Navi Mumbai Municipal Corporation (NMMC), and Maharashtra Pollution Control Board (MPCB). This intervention comes amid reports of severe pollution levels in December 2025, underscoring the court's frustration with inadequate enforcement and the urgent need for structured oversight to protect public health and the environment.

The decision, detailed in an order passed on January 29, 2026, and made available on February 3, 2026, reflects the court's growing concern over the failure of existing mechanisms, including a High-Level Coordination Committee formed in February 2024, to yield tangible improvements. News reports from sources like LiveLaw and Bar and Bench emphasize that pollution sources such as construction dust, industrial emissions, and vehicular traffic continue unabated, contributing to 44% of PM10 pollutants from resuspended road dust and construction activities alone. This ruling not only reinforces judicial activism in environmental governance but also sets a precedent for appointing expert judicial panels in ongoing pollution litigations across India.

Case Background

The case originated as Suo Motu PIL No. 3 of 2023, titled High Court of Judicature at Bombay on its own motion vs. State of Maharashtra & Ors. , triggered by alarming reports of moderate-to-severe air quality in Mumbai during October 2023. The court drew attention to a news article in The Indian Express quoting experts from the System of Air Quality and Weather Forecast and Research (SAFAR), who warned that Air Quality Index (AQI) readings between 200-300 affect vulnerable groups like children and the elderly, while levels above 300 impact the broader population. Pulmonologists from Hinduja Hospital compared prolonged exposure to fine particulate matter (PM2.5) to the health risks of smoking, prompting the court to register the PIL on November 6, 2023.

The petitioners, represented by the court itself in its suo motu capacity, targeted respondents including the State of Maharashtra, BMC, NMMC, MPCB, and other municipal corporations in the MMR. Intervenors such as the NGO Vanashakti and industry groups like NAREDCO West and the Bombay Charcoal Merchants Association joined the fray, raising concerns about enforcement gaps and economic implications. From the outset, the litigation focused on the relationship between urban development—particularly rampant construction—and deteriorating air quality, with events like uncovered construction debris at major sites (e.g., Mumbai Metro-3, Mumbai Coastal Road, and Bullet Train project) exacerbating the issue.

The timeline reveals escalating judicial interventions. Initial orders on November 6 and 10, 2023, mandated implementation of the Mumbai Air Pollution Mitigation Plan (March 2023) and guidelines from the Environment and Climate Change Department (October 25, 2023), holding Assistant Municipal Commissioners personally accountable. Subsequent hearings in February 2024 noted the formation of a High-Level Coordination Committee under a government resolution, tasked with coordinating urban local bodies. By November 2025, the court appointed an inspection committee of advocates and environmental experts to probe high-AQI sites, revealing non-functional air quality monitors and inadequate dust suppression at over 600 construction sites. Despite thousands of notices issued by civic bodies, pollution levels worsened, with December 2025 AQI reports classifying Mumbai's air as "very severe." The core legal questions centered on enforcing environmental compliance under statutes like the Environment (Protection) Act, 1986, the Air (Prevention and Control of Pollution) Act, 1981, and Motor Vehicles Act, 1988, while balancing urban growth against public health rights under Article 21 of the Constitution.

This background underscores a persistent dispute: civic authorities' failure to translate directives into action, leading to the court's latest recourse to an HPC for sustained monitoring.

Arguments Presented

Given the suo motu nature of the PIL, arguments were advanced primarily by the amicus curiae, intervenors, and respondents, rather than traditional petitioner-respondent binaries. Senior Advocate Darius Khambata, appointed as amicus curiae, played a pivotal role, submitting detailed notes on pollution sources and advocating for robust enforcement. He highlighted that resuspended roadside dust and construction activities account for 44% of PM10 levels, referencing a Global Burden of Disease Study (2019) that linked air pollution to 1.67 million deaths in India (18% of total deaths) and economic losses of US$37 billion (1.36% of GDP). Khambata proposed an HPC with judicial, technical, and medical expertise to supervise compliance, review ward-wise reports, and formulate a Graded Response Action Plan (GRAP) similar to Delhi's. He urged real-time monitoring via sensor-linked dashboards, increased CCTV at sites, and halting construction if 25% of monitors fail. He also called for "commando forces" of inspection squads—two for small wards, up to six for large ones—and weekly reports from Assistant Municipal Commissioners detailing non-compliances and actions.

Intervenors bolstered these contentions. Senior Advocate Janak Dwarkadas, for Vanashakti, demanded accountability for Assistant Municipal Commissioners, including compensation mechanisms for pollution victims, citing rising respiratory issues among infants, children, and women. Advocate Gulnar Mistry echoed health concerns, while Senior Advocate G.S. Hegde, for the Mumbai Metropolitan Region Development Authority (MMRDA), suggested display boards at sites for real-time pollution indicators. Industry intervenors like NAREDCO West and charcoal merchants sought balanced enforcement to avoid undue economic disruption.

Respondents, represented by civic bodies and the state, defended their efforts but faced scrutiny. Senior Advocate Shailendra Kamdar (BMC) and Anil V. Anturkar (NMMC) submitted affidavits claiming thousands of notices and stop-work orders, but admitted limitations like 91 daily squads inspecting only one site each (taking 2-3 hours). They reported budgetary allocations of Rs. 360 crore for 2024-25 deep cleaning drives but acknowledged "nothing worthwhile" achieved. Senior Advocate A.A. Kumbhakoni (MPCB) highlighted industrial audits (7,268 red-category and 7,841 orange-category units in MMR as of March 2024) but was criticized for "sailing on affidavits" without enforcement. Respondents objected to the HPC's proposed compensation role, citing Supreme Court precedents like Vishal Tiwari v. Union of India (2023) 4 SCC 332 and Delhi Pollution Control Committee v. Lodhi Property Co. Ltd. (2025 SCC OnLine SC 1601), arguing statutory regimes under the Air Act suffice. NMMC and BMC supported the HPC but resisted medical experts, suggesting additions like an IITM Pune representative, and emphasized providing infrastructure without overreach.

These arguments revealed a divide: proactive judicial and NGO pushes for stringent oversight versus authorities' claims of resource constraints and existing mechanisms, with the court noting the latter's "unsatisfactory" results.

Legal Analysis

The court's reasoning in the January 29, 2026, order builds on principles of sustainable development and the precautionary approach under environmental law, invoking Article 21's right to a pollution-free environment as established in Subhash Kumar v. State of Bihar (1991) 1 SCC 598. It critiques the "lackadaisical attitude" of authorities, observing that mere affidavits do not substitute for measurable pollution reduction, aligning with the "polluter pays" and "sustainable development" doctrines from Vellore Citizens Welfare Forum v. Union of India (1996) 5 SCC 647. The bench distinguished between procedural compliance (e.g., issuing notices) and substantive outcomes, noting failures like non-functional monitors at 600+ sites and uncovered debris at projects like Mumbai Metro-3.

Precedents played a key role. The court referenced Supreme Court orders in Arjun Gopal v. Union of India (W.P. (C) No. 1155/2020), restricting firecracker bursting to 7-10 p.m., and its own 2020 PIL order in PIL (St) No. 95794/2020 , enforcing similar guidelines—relevant for integrating festive pollution controls into broader strategies. On industrial emissions, it critiqued MPCB's audits (taking 7-8 months), drawing from M.C. Mehta v. Union of India (1987) 1 SCC 395, which mandated relocation of polluting industries. For construction, the analysis invoked CPCB guidelines on dust suppression (e.g., metal sheets, water sprinkling), emphasizing personal liability of officials under Section 5 of the Environment (Protection) Act, 1986, as directed to MPCB in November 2023.

The HPC's mandate—reviewing reports, recommending GRAP, and suggesting measures—stems from the need for independent oversight, akin to the National Green Tribunal's monitoring committees. The court clarified distinctions: while statutory bodies like MPCB handle consents, judicial intervention ensures enforcement where "collective efforts" fail, avoiding contempt for non-compliance. It addressed economic concerns by noting pollution's GDP impact (1.36%), balancing growth with health under Article 47 (duty to improve public health). No new sections were invoked, but the order reinforces Air Act enforcement, warning of construction bans if AQI persists, as hinted in January 2025 orders.

This analysis positions the ruling as an evolution in PIL jurisprudence, shifting from episodic directives to institutionalized monitoring for urban environmental crises.

Key Observations

The judgment is replete with pointed critiques of enforcement lapses, emphasizing the gap between directives and outcomes. Key excerpts include:

• On persistent pollution: "There is no dispute that the air pollution levels in the city Mumbai has not gone down, rather, in the month of December 2025 it was reported very severe." This underscores the court's frustration with unchanged AQI despite interventions.

• On compliance shortcomings: "The compliance so far made by the Municipal Corporations and the MPCB are not sufficient and satisfactory. This Court has been consistently observing the lackadaisical approach of authorities in ensuring compliance of the authorities despite specific directions. Mere filing of compliance affidavits is not sufficient." Here, the bench shifts focus from individual blame to systemic failures.

• On public project sites: "The attention of the authorities was drawn to seven major public project sites which were generating huge dust and causing severe air pollution but a periodic weekly review of those project sites... does not seem to be carried out or, at least, any such report is not given to the Court. This is within the sight of everyone that huge construction materials, rubble, earth and soil etc. are lying uncovered even today at several places." This highlights visible non-compliance at high-profile developments.

• On broader impacts: "The learned Amicus Curiae has submitted that the impact of air pollution is not only confined to health issues, rather, it impacts the national economy... about 1.67 million deaths in India in the year 2019 were attributable to air pollution... accounting for about US $ 37 billion which was 1.36% of India's GDP." Adopted by the court, this quote integrates economic rationale.

• On accountability: "The Municipal Commissioners are under a duty to identify the erring officers responsible for any lapses on their part in implementation of the guidelines." This reinforces personal liability, a recurring theme.

These observations, drawn verbatim, illuminate the court's rationale for HPC intervention.

Court's Decision

The Bombay High Court unequivocally decided to constitute the HPC, comprising Justice Amjad A. Sayed and Justice Anuja Prabhudessai, to "monitor and supervise compliance with the orders of this Court and reviewing the reports submitted by the Municipal Commissioner and other officials of the BMC, NMMC and the MPCB." The committee is empowered to recommend immediate, medium-, and long-term measures, including a GRAP for Mumbai and Navi Mumbai, and to submit a preliminary report by March 5, 2026, followed by monthly updates. It may consult experts like Virendra Sethi (IIT Bombay) and Dr. Indu Khosla (pediatric pulmonologist), conduct site visits, and hold weekly meetings initially. The BMC must provide logistical support—office space, vehicles, secretarial aid—and pay Rs. 1,00,000 honorarium per sitting per member, with the Deputy Municipal Commissioner (Environment) as nodal officer. Non-compliance invites contempt proceedings.

Practically, this decision mandates weekly ward-wise reports from municipal commissioners, real-time monitor linkages, and potential construction halts, directly addressing sources like the 11,000+ active sites. Implications are profound: it institutionalizes judicial oversight, potentially reducing PM10 by enforcing dust controls and industrial audits, benefiting 20 million MMR residents' health—especially vulnerable groups facing respiratory risks equivalent to smoking. Economically, it could avert GDP losses by curbing pollution's 1.36% drag, while pressuring authorities to optimize Rs. 360 crore budgets effectively.

For future cases, this sets a template for HPCs in environmental PILs, enhancing enforceability under the Air Act and Article 21. It may inspire similar panels in other polluted cities like Delhi, signaling courts' readiness to bridge implementation gaps. News coverage notes the order's alignment with Supreme Court GRAP models, potentially influencing national policy. Adjourned to March 5, 2026, the matter promises ongoing scrutiny, with the HPC's recommendations likely shaping MMR's air quality framework for years.
