New Delhi, Mar 20 (IANS): The Delhi High Court on Thursday pulled up the lawyer representing the death-row convicts in the Nirbhaya gang rape and murder case for not adhering to prerequisite technicalities before filing the petition.

Advocate A.P. Singh moved the High Court challenging the trial court's order which had declined to stay the execution scheduled for early morning on March 20.

"There is no annexure, no memo of parties, there is nothing in this matter, no affidavits, nothing. Do you have the permission to file this petition?" the judge asked the counsel.

Singh retorted, "Due to coronavirus, no photocopy machine is working."

The convicts, through their lawyers, moved the court after the trial court rejected their application seeking stay on their hanging.

The four convicts -- Vinay, Mukesh, Akshay, and Pawan -- are slated to be hanged by the noose on March 20 at 5:30 a.m. for brutally raping and murdering a 23-year-old physiotherapy student, later dubbed as 'Nirbhaya', on December 16, 2012.
