The bench of Justice Badar Durrez Ahmed and Justice Sanjeev Sachdeva had taken suo motu cognisance of the issue of air pollution in Delhi in April, following media reports on air quality in the city. An intervention application, filed by senior advocate Meet Malhotra, had also sought monitoring of the air quality inside the court premises. Air quality monitoring reports had also indicated high levels of particulate matter in the air inside the high court premises, prompting the bench to direct the court administration to conduct a thorough cleaning of the air conditioning vents and the carpets in the courtrooms. During the summer break, a large number of air vents in the HC premises were cleaned, and data from samples taken on July 6 and July 10 indicates that areas, where the vents were cleaned, had reduced amounts of particulate matter in the air. The cleaning of the vents and ducts in the extension building of the court, which houses most of the benches hearing criminal cases, will be completed soon. The report, which is based on real-time air quality monitoring (AQM) by the Centre for Science and Environment, suggested that the air near gate no 5 of the court premises, which faces Sher Shah Road and is the main entry and exit point of the court premises, was highly polluted. The report suggested that “simultaneous action” was needed for “aggressive control” of pollution in the “entire airshed of Delhi.
