The case drew the nation's ire and lead to the enactment of a new, far more stringent law on sexual assault, that's now begun to show results.
A two-judge bench of the HC ruled that their crime fell in the rarest of rare category. To press home the message, justices Pratibha Rani and Reva Khetrapal said that the appeals of convicts Vinay Sharma, Pawan Gupta, Akshay Thakur and Mukesh "are dismissed".
The parents of the 23-year-old — who died of the horrendous wounds inflicted on her in a moving bus by six despicable characters including a juvenile — were present in the court when the judges upheld the death sentences, which wasn't a surprise as the gang rape had lead to widespread protests.
The parents, with the mother draped in a green and black sari and the father sporting a grey sweater, displayed no emotions when the ruling came. They knew this was coming, and would be to their satisfaction.
In the HC complex itself, there was hardly any indication of the appeals being heard in the court. Lawyers went about their business with a silent purpose. It's known that many of them have their reservations on the death sentences awarded to the four convicts.
Outside the court complex, a bank of television cameras stood tiptoe on tripods, aiming their lenses at the exit gate. They had been there for nearly four hours, waiting silently. But within 10 minutes of the ruling, a commotion disturbed the relative quiet.
A group of young men and a burkha-clad woman suddenly came alive, throwing and stamping on copies of a book on the case written by AP Singh, defence lawyer of Akshay and Mukesh. Shouting slogans against the book, they called for its ban. This, even as Singh stood five feet away, giving bytes, justifying the book and its contents.
Simultaneously, another group of men and a lone girl, with black bands across their foreheads, started another island of commotion, holding up banners that read "HANG THE JUVENILE ALSO" and "DEATH FOR THE MUMBAI GANG RAPISTS". They kept up the chant "Na-Baalig Ko Bhi Phaansi Doh - Na-Baalig Ko Bhi Phaansi Doh".
Around that time, 15 minutes after 3pn, out walked the parents of the 23-year-old victim. That sent the cameras scurrying, to a make circles around the two. Finally, the cameras got their bytes, and the parents had their say. "We are satisfied, yes. But real closure will only come when all the rapists, including the juvenile, meet their maker," said the mother, with a quiet resolve, and not a morsel of mercy in her eyes. That statement drew the curtains on a day that for the most part was as quiet as a grave.
