The seers have been charged under Sections 120-B(criminal conspiracy) and 302 (murder) of IPC.
A total of 189 prosecution witnesses, including Sankararaman's widow, his son and daughter were examined during the trial between 2009 and 2011.
Eighty three of the witnesses had turned hostile during the trial.
