Sen was sentenced to lifetime imprisonment by a trial court in Raipur on Dec 24, 2010, on sedition charges over his links with Maoist ideologue Narayan Sanyal.
The bench reserved its judgment till Thursday, after hearing to the prosecution's argument. BJP MP and Senior lawyer Ram Jethmalani is defending Sen in court. Jethmalani argued that there was no believable evidence to convict Sen on the charges of sedition.
The defence counsels claimed that police has framed Sen in false cases as he was constantly opposing the alleged human rights violation by security force in tribal areas.
The prosecution opposed his bail appeal both on technical grounds as well as on the basis of merits of the case. It said that the documents recovered and the circumstances clearly shows his strong connections with Maoists.
Prosecution lawyer Kishore Bahaduri said, “The presumption that he is innocent is unfounded as his association with the Maoists have been proved through evidences beyond doubt."
Meanwhile, a group of 40 Nobel laureates from 12 different countries have written a letter to the Prime Minister and pressed for Sen's immediate release on bail.
