Ahmedabad: The Gujarat high court on Thursday directed the Centre to file an affidavit in a week’s time explaining why the court should not take punitive action against responsible persons for noncompliance of its order to supply CNG to Ahmedabad at a rate supplied to Mumbai and Delhi.

On July 25 last year, the bench headed by Chief Justice Bhaskar Bhattacharya ordered for conversion of all public vehicles to CNG and asked the Centre to provide gas to the city at the price at which it was supplied to metro cities.
