Supreme Court Revokes Protection for High-Polluting End-of-Life Vehicles in Delhi-NCR

In a significant move aimed at improving air quality, the Supreme Court on Wednesday withdrew legal protection previously granted to the most polluting category of End-of-Life (EOL) vehicles operating in the Delhi-National Capital Region (NCR), Hindustan Times reported.

The order specifically targets vehicles with emission standards of BS-III and below, effectively clearing the way for authorities to take action against them.

The court's ruling modifies its August 12, 2025 order, which had extended a blanket stay, preventing any coercive action against owners of End-of-Life Vehicles (ELVs)-defined as diesel vehicles older than 10 years and petrol vehicles older than 15 years in Delhi.

That August order had effectively paused the implementation of the Supreme Court's own landmark October 2018 judgment, which had upheld a 2014 National Green Tribunal directive. The 2018 ruling was a cornerstone of Delhi's anti-pollution drive, authorizing authorities to take polluting vehicles-specifically ELVs with outdated emission standards of BS-III and below-off the roads.

Following the August reprieve, thousands of these older vehicles returned to Delhi-NCR's streets. This development prompted the Commission for Air Quality Management (CAQM) to urgently review the environmental impact. The CAQM analyzed the emission load of these returning ELVs in comparison to modern vehicles compliant with the current, stringent BS-VI standards. Citing the severe pollution burden in the capital, the commission subsequently urged the Supreme Court to review its August directive.

The court's reconsideration occurred during a hearing on the overarching Delhi pollution case. Additional Solicitor General Aishwarya Bhati, appearing for the authorities, formally sought a modification of the order that granted protection against coercive steps for the older vehicles.

Accepting the CAQM's recommendation and the government's plea, a bench led by Chief Justice Surya Kant delivered a refined and targeted order. "Para 2 of the August 12, 2025 order is modified to the extent that no coercive steps shall be taken for BS-IV vehicles and above," the Chief Justice stated, as reported by Bar and Bench.

This clarification creates a critical distinction. It reinstates the threat of penalties-such as impounding or fines-specifically for vehicles with BS-III and older, far more polluting technology. However, it continues to provide temporary relief for the relatively cleaner category of BS-IV vehicles. By doing so, the court has adopted a calibrated approach, focusing enforcement power on the oldest and dirtiest vehicles that contribute disproportionately to harmful particulate matter and nitrogen oxide emissions, while acknowledging the different environmental impact of newer-generation ELVs.

The order is a decisive step to reclaim the gains of earlier judicial interventions in the long-standing battle for clean air in one of the world's most polluted megacities.
