Pawan Gupta, Akshay Kumar and Vinay Kumar Sharma's advocate AP Singh has urged the court to adjourn the executions "sine die" because Vinay's mercy plea is pending before the President.
Tihar Jail authorities has challenged the application of the three condemned prisoners as they are seeking stay on their execution and said "Only one convict's plea is pending and the others can be hanged."
However, the convict's lawyer resented with the jail authorities and said rules dictate that when one convict's plea is pending the others can not be hanged.
Mukesh Kumar, of the four convicts, mercy plea was disapproved by President Ram Nath Kovind on January 17 and Supreme Court had ripped-off the rejection appeal on Wednesday.
The trial courts, for the second time had issued black warrants on January 17, ordeering the execution of all the four convicts in Tihar jail on Saturday at 6 am. Prior to this, January 22 was scheduled as the date of hanging.
Vinay and Akshay's curative petitions have already been rejected by the Supreme Court. Yet, Pawan is left to file a curative petition.
Convicts can only move to the President to seek mercy if the apex court rejects the curative petition.
