The high court had in the fag end of last year issued directions to the neighbouring states of Delhi to prevent or curb the practice of stubble burning during autumn and winter months. It had also issued similar directions regarding bursting of crackers during Diwali.
The bench also directed the four neighbouring states of Delhi to indicate the "steps taken to contain and prevent air pollution".
It also made the National Capital Region Planning Board a party to the proceedings and listed the matter for hearing on July 18.

The directions came when the court was hearing a PIL initiated by itself to address the issue of rising air pollution in the national capital.
After perusing photographs of the area submitted by the amicus, the bench said the return of encroachments in the area along with the lack of a foot over bridge or access road to divert vehicles, the place has been turned into a "traffic nightmare".
Thereafter, the Railways assured the court that the entire work would be completed by October 1 this year.
