The former Director of Prosecution, Delhi, has shown a long term commitment towards AAP and its politicians.
Joon is believed to be a trial court specialist. He has appeared in majority of the cases filed against the AAP legislators, including a rioting case against Kejriwal, Sisodia and Gopal Rai, who were booked for protesting outside the house of then Prime Minister Manmohan Singh in 2012. It was Joon who got a discharge order from the trial court for the politicians.
He has represented the CM and Deputy CM on a number of occasions, and several AAP MLAs including Amanatullah Khan, Prakash Jarwal and Imran Hussain.
