New Delhi, Nov. 14 -- Supreme Court judge Justice PS Narasimha on Thursday sounded a grim warning over the worsening air quality in the national capital region (NCR), calling the situation "very serious" and urging lawyers to avoid physical appearances in court. Justices Narasimha, leading a bench that also comprised Justice Atul S Chandurkar, made the observation during the morning mentioning round, advising members of the Bar to use the virtual hearing facility instead of appearing in person given the alarming levels of pollution in Delhi. "Situation is very, very serious! Why are you all appearing here? We have the virtual hearing facility. Please avail it. This pollution will cause permanent damage," Justice Narasimha remarked from the bench. When senior advocate Kapil Sibal pointed out that many lawyers were already wearing masks, Justice Narasimha cautioned that such protection was inadequate. "Even masks are not enough. They will not suffice. We will discuss this with the Honourable Chief Justice as well," the judge said. Lawyers present in the courtroom described the exchange as a reflection of the visible concern within the judiciary about the hazardous air quality that has blanketed Delhi-NCR for days. According to the Commission for Air Quality Management (CAQM), Delhi's Air Quality Index (AQI) stood at 425 at 9 am on Thursday, placing it in the "severe" category. In the wake of the AQI, the CAQM has invoked Stage III of the Graded Response Action Plan (GRAP) across the Delhi-NCR, triggering a nine-point emergency response that includes a ban on construction activities, restrictions on diesel vehicles and other curbs aimed at reducing emissions. The comments by Justice Narasimha's bench come even as another Supreme Court bench led by Chief Justice of India Bhushan R Gavai continues to monitor the larger issue of air pollution in the region. On Wednesday, the CJI-led bench questioned the Punjab and Haryana governments for their failure to control stubble burning, a key contributor to the seasonal spike in pollution across the Indo-Gangetic plains. The apex court had asked both state governments to submit details of the steps taken to curb farm fires, even as satellite data showed thousands of such incidents over the past week. The Centre, too, was directed to coordinate with states to ensure that farmers are not forced to resort to burning crop residue. Meanwhile, The city woke up to another day of thick smog on Thursday as the air quality remained in the 'severe' category for the third consecutive day. The morning air quality bulletin issued by the Central Pollution Control Board (CPCB) showed an AQI reading of 404. Out of 37 monitoring stations, 27 reported AQI levels in the 'severe' range. These included Burari (433), Chandni Chowk (455), Anand Vihar (431), Mundka (438), Pusa (302), Bawana (460), and Wazirpur (452). The 'severe' category indicates a level of pollution that can affect healthy people and seriously impact those with existing diseases. The city reported its first 'severe' air quality day of the season on Tuesday, when the AQI was recorded at 428, the first such instance since December 2024. An AQI between 0 and 50 is considered 'good', 51 to 100 'satisfactory', 101 to 200 'moderate', 201 to 300 'poor', 301 to 400 'very poor' and 401 to 500 'severe', as per the CPCB classification. The minimum temperature settled at 10.6 degrees Celsius, 2.9 notches below the season's average with the maximum temperature likely to hover around 27 degrees Celsius....
