Justice Vipin Sanghi asked the BJP leader to file his reply by November 17 to Kejriwal's application seeking dismissal of Gupta's election petition.
Gupta, who is also the Leader of Opposition in Delhi Assembly, in his petition has sought that the election of Kejriwal in 2013 be declared as void as the AAP leader had exceeded the poll expense limit of Rs 14 lakh.
Kejriwal in his plea has said that the unsigned affidavit was noticed during Gupta's cross examination by a court of Joint Registrar, which in its order held that it was not an affidavit in the eyes of the law as it was unsigned and hence the petition is without any affidavit.
On September 26, 2014, the court had framed the issues to be decided on the election petition, saying it would decide whether the expenses incurred by Kejriwal in the 2013 assembly elections were in contravention of the Representation of People Act and whether he had indulged in corrupt practices within the meaning of the Act.
