The Supreme Court on Wednesday dismissed Nirbhaya convict Mukesh Kumar Singh’s petition challenging the rejection of his mercy plea and said that the expeditious disposal of a plea does not mean non-application of mind by the President of India.

A three-judge bench headed by Justice R Banumathi and comprising Justices Ashok Bhushan and A S Bopanna, said that alleged sufferings in prison can’t be grounds to challenge the rejection of a mercy petition.

It said all relevant material, including judgments pronounced by trial court, high court and Supreme Court, were placed before President Ram Nath Kovind when he was considering the mercy plea of the convict.

Mukesh is one of the four men on death row for the 2012 gangrape and murder of a physiotherapy intern in Delhi. The trial court has issued black warrants for the execution of the four -- Mukesh, Pawan Gupta, Vinay Kumar Sharma and Akshay Kumar -- at 6 AM on February 1.

President Kovind rejected Mukesh’s mercy plea on January 17.

The apex court bench rejected Mukesh’s counsel’s contention that the entire material of the case was not placed before the president when he was considering the mercy plea.

The bench, while referring to two files placed before it by the Centre on Tuesday, said all relevant documents were sent according to the January 15 covering letter by the Delhi government to the Ministry of Home Affairs.

The bench noted that detailed judgements of trial court, high court and the Supreme Court, Singh’s curative petition, his past criminal history and his family background were sent to the Home Ministry by the Delhi government.

“All the documents were taken into consideration by the president while rejecting the mercy petition,” the bench said. It also dealt with submissions advanced by the convict’s counsel, who argued that the mercy plea was rejected at "lightning speed".

The bench said if a mercy petition is expeditiously dealt with, it cannot be assumed it has been adjudicated upon with a preconceived mind.

Mukesh had moved the mercy plea after the Supreme Court dismissed his curative petition against his conviction and death sentence. Of the other three, the apex court has also rejected the curative petition of Vinay. Akshay approached the Supreme Court on Wednesday with a curative petition. And Pawan is yet to file a curative plea before the apex court.

The 23-year-old physiotherapy intern, who came to be known as ‘Nirbhaya’, the fearless one, was gang-raped and savagely assaulted on the night of December 16, 2012, in a moving bus in south Delhi. She died of her injuries a fortnight later in a Singapore hospital.
