Supreme Court on Monday questioned the Delhi government over the delay in enforcing Stage 4 of the Graded Response Action Plan (GRAP) despite the alarming rise in pollution levels in the national capital.
A bench comprising Justices Abhay S Oka and Augustine George Masih highlighted the delay in enforcing stage 4 measures of the GRAP despite the Air Quality Index (AQI) reaching critical levels in the national capital.
The counsel for the Delhi government informed the bench that stage 4 of GRAP had been enforced starting Monday, which includes a ban on heavy vehicles entering the national capital.
The apex court stated that it would not permit any reduction in preventive measures under stage 4 of GRAP, even if the AQI drops below 450.
“The moment the AQI reaches between 300 and 400, stage 4 has to be invoked. How can you take risk in these matters by delaying applicability of stage 4 of GRAP,” the bench told the counsel.
The court directed the state government to explain the steps it has taken to address the alarming rise in pollution levels.
The implementation of GRAP Stage 4, the strictest level of anti-pollution measures under the Graded Response Action Plan, has drawn significant attention.
The Delhi government introduced these measures on Monday at 8 am. following a sharp decline in air quality to the “severe plus” category.
Delhi chief minister Atishi announced on X (formerly Twitter) that starting Monday, all schools will shift to online classes, except for students in Classes 10 and 12.
