The Supreme Court recently said that citizens, not courts, must lead the fight against air pollution. Examine the limits of judicial intervention in environmental governance.

On 6 November 2026, a Bench headed by CJI Surya Kant called vehicular emissions a year-round threat to Delhi-NCR's air. It said the people, not the judiciary, must "strike a blow" against pollution [1]. The remark admits that courts cannot govern the environment alone, even with a broad reading of Article 21.

Limits of judicial intervention

• Limited technical expertise: The 10-year diesel and 15-year petrol limits come from NGT and SC orders, not a statute [7]. They go by a vehicle's age, not by how much it emits.
• Reacting to crises: Court action peaks around Deepavali and winter. Vehicle pollution, however, comes from millions of daily travel choices [1].
• Dependence on the executive for enforcement: Courts cannot put ANPR cameras in fuel stations or roll out the phased fuel ban district by district. CAQM had to push back the start of Direction No. 89 [4].
• No data of their own: A Parliamentary Standing Committee found Delhi's source apportionment studies (which measure how much each source adds to pollution) out of date [3]. Courts cannot produce such evidence.
• Federalism and accountability: Coordinating Delhi, Punjab, Haryana, Rajasthan and UP is a statutory job for CAQM under the 2021 Act [2]. When courts keep supervising, it blurs who is answerable and strains the separation of powers.
• Fairness and money: Bans without alternatives hurt small transporters. Funding replacement vehicles is a budget decision. The Cabinet's NCRPB scheme targets trucks and buses, which are 3% of vehicles but about 36% of transport PM2.5 [6].

Where courts still add value

• The Bench looked past the Deepavali spike to the lasting vehicular source. This shows courts can reset the agenda when regulators lose focus [1].

Way forward

• Rules based on emissions: CAQM's Expert Committee (December 2025) should review BS norms and the shift to electric vehicles [5].
• Fresh source studies, updated regularly [3].
• Support with every ban: replacement subsidies, more buses and charging points [6].
• Citizens: shared mobility and cleaner vehicles, in line with the duty in Article 51A(g).

Judicial activism has protected the right to clean air, but it cannot replace good administration. The best path is shared responsibility: expert regulators, States that work together, and citizens with real choices. Courts should act as a backstop for accountability. That approach serves Articles 21 and 48A and SDG 11.6.
