Advocate Anupam Srivastava, appearing for Kejriwal, said they intended to appeal against the order.
Jaitley had filed the defamation suit in 2015 seeking Rs 10 crore damages from Kejriwal, Raghav Chadha, Kumar Vishwas, Ashutosh, Sanjay Singh and Deepak Bajpai.
The AAP leaders had allegedly attacked Jaitley and his family members in various fora, including social media, over alleged irregularities and financial bungling in the Delhi and District Cricket Association (DDCA), of which he was the president for about 13 years till 2013.
Jaitley has already denied all the allegations.
