All four were arrested along with Gautam Navlakha on August 28 under sections of the Unlawful Activities Prevention Act (UAPA) and IPC, on charges that they were part of a larger conspiracy of the banned CPI-Maoist.
In its appeal, the state said the High Court had erred in entertaining the petition, which sought a writ of Habeas Corpus, and said it was “clearly against the law laid down” by Supreme Court in earlier cases.
The Pune police had arrested Navlakha in Delhi last month following searches in several cities. A transit remand was also secured from Saket district court in South Delhi to take him to Pune. The order was later stayed by the high court.
