"The session has been postponed. There is no information on when would be the next session," ADGP (Prisons) J K Tripathy told PTI.
The hearing was to take place today on Perarivalan's Right to Information (RTI) application seeking to know the grounds on which the President had rejected his mercy petition.
Perarivalan is lodged in the Central Prison at Vellore, along with two other death row convicts Murugan and Santhan, whose execution, scheduled for September 9, 2011, was stayed by Madras High Court for six weeks in August of that year. The case has since been transferred to the Supreme Court.
