The plea alleged that in the Nirbhaya
case, the convicts at different points during the investigation, had pleaded to undergo tests such as polygraph, lie detector and brain mapping, but all such pleas were declined without any justification.
It urged the International Court of Justice (ICJ) to launch an "urgent investigation" into the possibility of false testimony by the sole eyewitness, the friend of the victim, in the case.
The petition claimed that the convicts have been treated as "guinea pigs" and have been falsely implicated in the case and it urged the ICJ to order urgent probe into the matter.
"The fact whether the convicts are guilty of culpability or there has been public and media pressure to falsely implicate the convicts or to treat them as guinea pigs to save others and accept the hypothesis that the prosecution has booked them at the instance of some political executives or to save a situation which disturb society perceives as a collective catastrophe on the paradigm of social stability and to sustain its faith in the investigation to keep the precept of rule of law alive," said the petition.
"In essence, the submission is that the whole exercise, namely, investigation and trial has been carried out with the sole purpose for the survival of the prosecuting agency in India, which is a big miscarriage of justice in India," said the petition.
On March 5, a trial court had issued fresh warrants with March 20, 5.30 am, as the date for the execution of the convicts — Mukesh Singh (32), Pawan Gupta (25), Vinay Sharma (26) and Akshay Kumar Singh (31).
A 23-year-old physiotherapy intern, who came to be known as 'Nirbhaya' (fearless), was gang raped and savagely assaulted in a moving bus in south Delhi on December 16, 2012. She died after a fortnight.
Six people, including the four convicts and a juvenile, were named as accused. Ram Singh, the sixth accused, allegedly committed suicide in Tihar Jail days after the trial began in the case.
The juvenile was released in 2015 after spending three years in a correctional home.
