The bench of Justice H C Mishra granted bail to Barla, who was in jail since her surrender to a local court.
Barla had on October 16 surrendered before the Ranchi court and was sent to judicial custody in connection with an agitation she had led in 2006.
Two days later, she obtained bail from the court, but was re-arrested on a second warrant following an FIR charging her with obstructing government work at Nagri, when she had joined the villagers to protest land acquisition for setting up an educational hub here.
Barla came to limelight after leading agitations in Gumla and Khunti districts against land acquisition for a steel project.
