In his letter to President Kovind, Vinay Sharma said his mercy plea was sent "fraudulently".
Vinay Sharma, one of the four convicts in the 2012 Delhi gang rape and murder case, on Saturday sought the withdrawal of his mercy plea from President Ram Nath Kovind, saying it was sent without his consent.
The convict wrote to the president, alleging his mercy plea, which was forwarded to him from the Ministry of Home Affairs, had been sent by the Tihar jail authorities with a "malafide intention" and in "criminal conspiracy" with the Delhi government.
Sharma said he was yet to exhaust all legal remedies available to him before filing the mercy plea as he has not filed any curative petition before the Supreme Court.
"It is therefore prayed to your kind honour that until the exhaustion of the judicial remedies, including those yet to be filed and/or pending in the Delhi High Court and the Supreme Court by me as well as my co-accused, you may allow me to withdraw this mercy petition which has been filed without my consent and signature.
"Additionally, you are requested in the interim not to take any decision on my mercy petition," Sharma said in the letter, sent through his lawyer A P Singh.
In his letter to President Kovind, Sharma also said his mercy plea was sent "fraudulently", without attaching any document detailing the mitigating circumstances of his case and by concealing various important facts so that it is rejected.
The convict also pleaded that taking any step on his mercy plea would amount to a grave injustice as he was yet to exhaust all his judicial remedies.
A Delhi court had recently directed Tihar Jail authorities to produce the four convicts before it on December 13 so that they can brief the court about the status of their petitions.
The court was hearing a plea by the victim's parents who have sought a direction to the jail authorities to expedite the execution of the convicts.
The victim's parents had approached the court saying the convicts have exhausted all legal remedies.
In December last year, the woman's parents had approached the court to fast-track the procedure to hang all four convicts in the case.
The Supreme Court on December 12, 2018, had dismissed a Public Interest Litigation or PIL seeking direction to the centre to execute the death penalty awarded to the four convicts - Mukesh, Pawan, Vinay and Akshay - in the gang rape and murder case.
The men had gang-raped and tortured a 23-year-old physiotherapy intern in a moving bus in South Delhi by six men, including the bus driver, conductors and helpers.
The woman had boarded the nearly vacant bus in Munirka in South Delhi along with her male friend on her way back home on December 16 that year. After raping and brutalising the woman and beating her friend, the assailants had thrown them out of the bus.
After receiving initial treatment in New Delhi for a few days, she was transferred to the Mount Elizabeth Hospital in Singapore, where she died from her injuries on December 29, 2012.
