In his opinion, Parasaran said the "course of action" adopted by Arvind Kejriwal government is against the federal structure of the country. But he has cautioned that the Delhi Lieutenant Governor should not take steps to get the FIR declared as "non est" (non-existent).

"The Solicitor General (SG) appears to be trying to create an erroneous impression that even if any central minister allegedly commits a crime in Delhi, then no action can be taken against such a minister," the statement added.
