The appeal was filed in Pilibhit sessions court.
Government counsel Abhay Saxena moved the appeal in the court of District Judge Vinod Mishra.
The court fixed June 15 as the next date of hearing in which Varun would be required to appear.
On March 5, chief judicial magistrate Abdul Quayyum had acquitted Varun in connection with a hate speech case lodged against him in Barkhera police station during the Lok Sabha election in 2009.
Interestingly, Senior Congress leader Beni Prasad Verma, has alleged that Varun was exonerated in the cases due to a "tacit understanding with the Samajwadi Party-led government in Uttar Pradesh.
