Geelani was accused of sedition after he had organised an event in February at the Delhi press club. The event was organised on the death anniversary of Afzal Guru who sentenced to death after being held guilty in the Parliament attack case.
The bail was granted by additional sessions judge Deepak Garg.
The Delhi police accused Geelani of being the main organiser of the event where there were alleged anti national sloganeering. The police had opposed his bail stating that it would hamper investigation if he was set free.
However the defence counsel said that it served no purpose of his client being in jail. He is in judicial custody and it serves no purpose to the probe his lawyer had argued.
The court had on Friday reserved its order.
The Patiala House court had granted bail to Umer Khalid and Anirban Bhattacharya yesterday also accused of sedition in connection with the JNU sedition case.
Earlier this month Kanaihya Kumar the JNU student leader had been granted conditional bail by the Delhi High Court for six months.
