A three-judge bench of the Supreme Court, through a unanimous verdict, upheld the Delhi High Court judgement on death penalty to the four convicts.
She said separate fast track courts must be to dispense such cases in a timely manner.
The judgement was received with an applause from those in the court.
"The demonstrations demanding justice for the victim reflect not only the public revulsion at the brutality of her attack, but also the simmering rage over the prevalence of sexual violence in India", NPR's Julie McCarthy reported in 2012.
India's top court has upheld the death sentences of four men who were convicted of the murder, gang-rape and torture of a 23-year-old medical student on a moving bus in New Delhi almost five years ago.
The court held that the diabolical nature of the crime in the Indian capital, which triggered massive protests across the country, made it a fit case for the death penalty. The Delhi High Court upheld the decision of execution of four convicts - Akshay (29), Mukesh (27), Pawan (20) and Vinay (21).
Speaking over phone, the victim's mother termed the verdict as a victory of justice.
The court referred to the dying declaration of the young woman and said the "brutal and demonic" crime had been proved beyond doubt. Convicts of the Nirbhaya case including Akshay Thakur, Pawan Gupta, Vinay Sharma, Mukesh Singh have been given death sentence by Supreme Court as a effect of the crime they committed. A 23-year-old student, Jyoti was gang-raped and tortured on her way back home in Delhi in December 2012.
"The fact is that the road to justice is very, very long in this country", she said. She died two weeks later of injuries in a hospital in Singapore, where she was taken for treatment. The criminals threw her out of their vehicle with her male friend.The UP (Uttar Pradesh) government survived her and looked after her till December 29th.
It also said there was no delay in registration of FIR and added that "even assuming for the sake of argument that there is delay, the same is in consonance with natural human conduct". No sooner the order of the court was read out loud, the jam packed court began to applaud. The Court awarded the death sentence to the four prisoners who committed the gape-rape.
