Pleading not guilty, the AAP leader said the complainant is not an aggrieved person and the complaint against him is false.
Dikshit's political secretary Pawan Khera had filed a defamation case against Kejriwal for allegedly making "derogatory remarks" and "baseless" allegations against her last year during protests on power tariff hike.
He accused Kejriwal of using "false and filthy" language against Dikshit in a television show.
