This order issues interim directions and calls for responses; it imposes no new vehicular restriction, records no finding on emission norms, and decides nothing on the merits of the five air-pollution aspects. The GRAP compliance figures were presented by the amici curiae, not adjudicated by the Court.

The order
On 6 November 2026, a three-judge Bench of the Supreme Court headed by Chief Justice Surya Kant, with Justices Joymalya Bagchi and V. Mohana, directed the Municipal Corporation of Delhi, the Government of NCT of Delhi, the Delhi Police (Traffic Department) and the States of Haryana, Rajasthan and Uttar Pradesh to file detailed responses on vehicular emissions in Delhi and the National Capital Region (NCR), and gave all States two weeks to place their submissions on record.
The order was passed in Suo Moto Writ Petition (Civil) No. 11 of 2026, a case the Court registered to deal with air pollution in the NCR. The Bench also fixed dates in November for four linked suo motu cases, each dealing with a separate facet of the problem, and said the present case would be treated as the lead matter and listed on each of those dates.
How this case began
The suo motu petition was registered following directions in a judgment dated 12 March 2026 in W.P. (C) No. 13029 of 1985, in which the Court dealt with the degrading air quality in the NCR. In that judgment, the Court directed the registration of five separate suo motu writ petitions, each pertaining to a separate aspect of air pollution in the NCR, and clarified that the new cases were not a closure of the proceedings in the older writ petition but a re-shaping of them.
At the hearing on 6 November, Additional Solicitor General Aishwarya Bhati appeared for the Union of India and the Commission for Air Quality Management in National Capital Region and Adjoining Areas (CAQM). Senior Advocates Aparajita Singh and Uttara Babbar and Advocate Shibani Ghose appeared as amici curiae, and counsel for the various parties addressed the Bench on the steps taken so far to curb air pollution in Delhi-NCR.
What the amici showed the Court
Ms. Bhati highlighted efforts taken by the Union of India and the States and the NCT, including restrictions on vehicular emissions and measures to reduce stubble burning. The amici curiae, however, pointed out that compliance with previous orders, especially those dated 21 January 2026 and 23 February 2026, was yet to be properly reported to the Court.
The amici also placed before the Bench a graphical representation of compliance with the Graded Response Action Plan (GRAP) for the period between 21 October and 3 November 2026. The data indicated a substantial decline in incidents of stubble burning across Delhi and the States of Uttar Pradesh, Haryana and Rajasthan. The Court recorded that the same data also brought to the fore a converse and equally pressing concern: a sharp increase in issues attributable to vehicular emissions.
The six questions the authorities must answer
The Court observed that Delhi and the NCR, by virtue of their geographical and economic interconnectedness, bear the cumulative burden of vehicular traffic originating not only within their own boundaries but also from the neighbouring States of Uttar Pradesh, Haryana and Rajasthan, compounded by the volume of commercial and non-commercial vehicles entering and plying within the city. It said there could be little doubt that the issue warranted urgent and immediate intervention.
The authorities must specifically address six aspects: (i) the existing regulatory framework and enforcement mechanisms governing the entry and plying of commercial and non-commercial vehicles within Delhi and the NCR, particularly those from neighbouring States; (ii) the measures in place to identify, monitor and regulate vehicles that do not conform to prescribed emission standards, including enforcement of Pollution Under Control (PUC) certification requirements; (iii) the steps taken to prevent the entry and operation of overage, end-of-life or otherwise non-compliant vehicles; (iv) the enforcement measures undertaken against violations, including the number of vehicles inspected, challaned, denied entry or otherwise proceeded against; (v) the coordination mechanisms between the authorities of Delhi and the neighbouring States for regulating inter-State vehicular movement and ensuring compliance with applicable emission norms; and (vi) any further short-term and long-term measures proposed or contemplated to mitigate vehicular emissions and reduce their contribution to the deteriorating air quality in Delhi and the National Capital Region. The authorities must also indicate the specific measures proposed to strengthen the existing enforcement mechanisms, together with a time-bound roadmap for their implementation.
Separately, the Court granted the States two weeks to place on record their submissions on the steps taken by them, their responses to each of the suggestions of the CAQM and the amici curiae, and any action they independently propose to take.
Four cases, four dates
The Registry was directed to list four cases on the dates indicated: SMW (C) No. 12 of 2026, on vehicular emissions and pollution, on 23 November 2026; SMW (C) No. 15 of 2026, on solid waste management and the burning of crop residue and firecrackers, on 25 November 2026; SMW (C) No. 14 of 2026, on pollution by construction activities, power plants and other industries, on 26 November 2026; and SMW (C) No. 13 of 2026, on the conservation and enhancement of green cover, on 30 November 2026.
The amici curiae were requested to file short notes, apart from any lengthier written submissions, at least two days before the hearing of the respective issues. The Registry was directed to ensure compliance with paragraph 19 of the 12 March 2026 judgment, and the present suo motu petition is to be treated as the lead matter and listed on each of the above dates. The Court also directed that Ms. Shibani Ghose be recorded as the 'filing Amicus' so she can file documents through the e-filing portal.
BANTHRY ANALYSISFor law students
This order is an example of a continuing mandamus: the Court does not decide the merits of air-pollution policy in one stroke but keeps the matter on its board, calls for information, and issues directions in stages. The restructuring of one long-running writ petition into five linked suo motu cases shows how the Court separates a sprawling problem into facets - vehicular emissions, green cover, construction and industry, waste and stubble - so each can be heard and monitored on its own track while the lead matter holds them together.
Note what the order does not do. It records data placed before it by the amici curiae without treating that data as a finding of fact, and it asks for responses rather than imposing new restrictions. For students, the discipline is to distinguish three things in such orders: what the Court was told (submissions and data), what the Court directed (here, detailed responses on six specified aspects before the next date of hearing, and the States' submissions within two weeks), and what remains undecided (the merits of each facet, to be taken up on the listed dates).

- On what basis did the Court register SMW(C) No. 11 of 2026, and why did it split the air-pollution proceedings into five separate suo motu cases?
- What did the GRAP compliance data for 21 October to 3 November 2026 indicate, and what contrasting concern did the Court highlight?
- What are the six aspects on which the Court directed the authorities to file detailed responses, and what is the status of those directions?
