Gupta said both the leaders indulged in "corrupt practices" and incurred huge expenditure of nearly Rs.94.80 lakh during the campaign by organising a rock show "Jeet Ki Gunj, Vote for Change" Nov 23, 2013 at Jantar Mantar after filing their nomination papers.
Many singers and Bollywood personalities performed at the event and all of them charged Rs.3-10 lakh, which was paid by Kejriwal, Gupta alleged.
Gupta said the expenditure was "highly underestimated by the respondent (Kejriwal) and the Aam Aadmi Party as Rs. 14.72 lakh".
Filing the petitions through advocate Ajay Digpaul, Gupta moved court against Kejriwal, his rival from the New Delhi constituency, while Mehra moved court against Bharti, who defeated her in the Malviya Nagar constituency.
