Supreme Court Highlights Severe Post-Diwali Air Pollution in Delhi

The Supreme Court of India voiced serious concern regarding the worsening condition of air quality in the national capital around the festival season. During proceedings on October 28, 2026, the bench observed that air pollution levels in Delhi tend to become significantly worse following Diwali celebrations.

The oral remarks arose during a routine scheduling exchange between the bench and Senior Advocate Indira Jaising. The exchange brought to the forefront the day-to-day physical realities faced by public officials and residents in the National Capital Region who must work on-site despite severe environmental hazards.

Background

The dialogue began when the Supreme Court was setting a future date to hear a pending matter. Senior Advocate Indira Jaising requested that the case be listed on November 17, following the Diwali vacation, noting that the period around Diwali is marked by severe air pollution in Delhi. Counsel representing the opposite party, however, preferred an earlier date during the first week of November.

Justice Vikram Nath suggested taking up the hearing before the festive holidays rather than afterwards. The judge pointed out that atmospheric conditions prior to the festival would be comparatively cleaner than the dense haze that typically settles over the capital once celebrations conclude. Counsel noted that pollution persists both before and after the festivities, leading to further discussion on the practical difficulties faced by the judiciary.

Official environmental records reflect this regular seasonal decline. During the previous year, Delhi's 24-hour average Air Quality Index rose from 268 on October 18, 2025, to 345 on Diwali day, eventually climbing to 353 on October 22 in the 'very poor' category. In late October 2026, the Commission for Air Quality Management invoked Stage I of the Graded Response Action Plan after AQI measurements hovered in the 'poor' category.

What the Court Said

Highlighting the reality of continuing court work during critical environmental periods, Justice Vikram Nath emphasized that judges do not have the choice of staying away from the courtroom. The judge drew a distinction between legal practitioners, who have the facility to argue their matters through remote video conferencing, and the bench, which must be physically present inside the courtroom.

"We can't sit at home. You have the privilege of sitting at home and saving yourselves from the pollution, but we can't"

The exchange also touched upon the broader context of judicial monitoring of Delhi-NCR pollution. In earlier proceedings under the MC Mehta v. Union of India matter, a bench comprising Justice Abhay Oka and Justice Ujjal Bhuyan had strictly scrutinized the enforcement of anti-pollution measures, including firecracker prohibitions across Delhi and adjacent districts in Haryana and Uttar Pradesh.

Those earlier orders reiterated that authorities must enforce restrictions effectively. The court had previously observed that no religious practice requires activities that cause dangerous environmental harm or compromise public health, leading to orders upholding comprehensive prohibitions on the manufacture, storage, sale, and bursting of crackers.

The Law Explained Simply

Air quality monitoring in the National Capital Region is carried out through structured regulatory mechanisms designed to respond to rising pollution numbers. One major framework mentioned in the proceedings is the Graded Response Action Plan, known as GRAP. This administrative mechanism automatically activates progressive curbs on polluting activities depending on how high the Air Quality Index climbs.

When air quality deteriorates into categories such as 'poor' or 'very poor,' administrative authorities like the Commission for Air Quality Management issue mandatory operational restrictions. In addition, the Supreme Court has consistently treated clean air and public health as essential protections under the Constitution when passing continuous directions against hazardous industrial emissions, open burning, and unapproved firecrackers.

The court has also maintained a strict threshold regarding exemptions for alternative products such as green crackers. The judiciary has previously ruled that exemptions cannot be granted unless clear scientific proof shows that such alternatives reduce emissions down to a bare minimum.

Impact on Common People

The remarks from the bench emphasize the widespread vulnerability shared by all citizens living in the National Capital Region. While certain professionals may have access to hybrid working tools and remote platforms to minimize outdoor exposure, ordinary workers, court staff, and public servants must commute and work in open environments regardless of hazardous conditions.

The issue touches the general public directly because seasonal spikes in air pollution cause severe respiratory stress, especially for young children and elderly citizens. Furthermore, ongoing court monitoring directly influences daily life through municipal rules, such as restrictions on firecracker sales, construction activities, and vehicle usage during high-pollution periods.

Residents and business operators in Delhi and surrounding NCR districts in Haryana, Rajasthan, and Uttar Pradesh also face strict enforcement of environmental guidelines designed to curb industrial fumes, stubble burning, and waste fires.

What To Do in a Similar Situation

Citizens and organizations seeking to address severe pollution or navigate regulatory curbs in the NCR should consider the following practical measures:

• Monitor official daily updates from the Commission for Air Quality Management to understand which stage of the Graded Response Action Plan is active.
• Comply strictly with regional prohibitions regarding the sale, storage, or lighting of firecrackers to avoid administrative and penal action.
• Keep proper maintenance records and valid emission certificates for private and commercial vehicles to ensure compliance with transport curbs.
• Report illegal industrial emissions, open waste burning, or construction dust violations to local municipal bodies or pollution control boards.
• Seek appropriate legal guidance from a qualified lawyer before challenging environmental restrictions or when facing penalties under pollution control orders.
