A bench of Justice S K Mishra issued the notice to the EC on July 18 making it returnable by August 17, so that the writ petition shall be taken up for final hearing on August 22.
The high court has also made it clear in the order that the matter shall be disposed of at the stage of admission, informed the petitioner advocate Sidharth P. Das.
He also alleged "discrepancies" in the sworn statements of expenses both by Patnaik and his party Biju Janata Dal, of which he is the president.
"Though, the EC was supposed to act upon such complaints and redress the grievances of the complainants within two days, the EC is sitting over it for more than one year now," the writ petition alleged, adding that such prolonged silence on the part of Election Commission was illogical and bad in the eyes of law.
