The Supreme Court on Wednesday took Punjab, Haryana government to task over stubble burning leading to Delhi air pollution. On October 16, the Court summoned Chief Secretaries of the Punjab & Haryana governments after expressing severe disapproval over the lack of proper legal action against stubble burning in the state. In the last hearing, the Court noted that not a single prosecution had taken place against stubble-burning incidents. It had asked the Commission for Air Quality (CAQM) to take penal action against state officers for failing to discharge their functions.
