The Supreme Court on Friday told Solicitor General Tushar Mehta that the court is not concerned with any commission, all it wants on a priority basis is for the Centre to ensure that there is no smog in the city. The CJI Bobde also asked Mehta that grading of offences was required. "We need details what kind of offences you are looking at. Because for all offences and violation of orders of the commissions or provisions, the penalty cannot be 5 years jail or Rs 1 crore fine," added Bobde. Sidharth Pandey reports
