After enforcing GRAP-3 (Nov 15, 2024) and GRAP-4 (Nov 18, 2024) in Delhi and surrounding regions, the Supreme Court of India intervened and asked Commission for Air Quality Management in the National Capital Region & Adjoining Areas (CAQM) to keep GRAP-4 in place until further notice. In a hearing on December 5, 2024, the Supreme Court allowed GRAP-4 and GRAP-3 to be retracted for the time being as the air quality appears to have improved enough.

According to CAQM, the AQI in Delhi stood at 165 at 4PM, which is 135 points below the threshold for GRAP-2 (AQI 300-400). Still, the court ordered CAQM to keep the GRAP-2 in force. The GRAP-4 comes into action when AQI goes over 450 but remained in place despite the AQI falling low enough to retract GRAP-2 and above.
