CJI NV Ramana told the Solicitor General: "Even though the pollution has come down, we are not going to close this matter. We are going to continue to give directions. Almost every day or every second day, we have to hear this. The AQI is 381 at present. Your figure of 290 may not be correct. I don’t think there is any substantial change. There may be a little less pollution, but it’s going to get serious again. Take [mitigation] measures for another 2-3 days."
