NDTV has learnt that while most convicts get the chance to be heard by the board after around 20 years in jail, the case of Manu Sharma, the son of a Congress politician, is being pushed by Tihar Jail authorities in just 14 years. Most of the other convicts have spent more than 15 years in prison.
Despite numerous calls, Tihar jail officials have not responded to the question on why they chose to recommend Manu Sharma for an early release.
The 41-year-old was sentenced to life in jail for shooting model Jessica Lall at a party after she refused to serve him a drink on April 30, 1999.
The 49-year-old conveyed her view in a handwritten letter to Tihar Jail, which had asked for her feedback on Manu Sharma's release - something that jail officials claim they do in high profile cases where the prisoner has displayed good behaviour.
For the last three months, Manu Sharma has been in an open jail; he is allowed to leave the prison for work at 8 am and return at 6pm. Each year, only five prisoners are rewarded this way for "good conduct".
Manu Sharma, aka Sidharth Vashishta, works with an eponymous non-profit for the rehabilitation of prisoners.
Another high profile convict Sushil Sharma, a Congress politician in jail for the last 23 years for killing his wife Naina Sahni and trying to burn her body in an oven or tandoor - which gave the case the name "tandoor murder" - has been denied early release because his crime was considered 'heinous'.
