Priyadarshini Mattoo

In a 450-page judgment the judge came down heavily on the role of Delhi Police; "There has been particular inaction by Delhi Police", he said, while commenting that the accused’s father may have used his official position to influence the agencies. "The influence of the father has been there in the matter and there was deliberate inaction" (at the time his father was second in command of the police forces in Delhi).

He further stated that the rule of law doesn’t seem to apply to the children of those who enforce it.

The judgment held the CBI responsible for unfair investigation and failure to produce Virender Prasad, Mattoo’s household help, which resulted in the obstruction of justice. The police had claimed Prasad had gone missing and was not traceable, yet in the aftermath a journalist could easily find him in his Bihar village.

Santosh Singh, post conviction, spent 4 years behind bars and was out on parole in March 2011. Upon return, he subsequently filed another application for grant of parole (subject matter of Criminal Writ Petition 224/2012) before Delhi High Court. The High Court granted him a parole of another month on 6 March 2012.

In October 2010, the Supreme Court upheld the conviction of Santosh Kumar Singh but reduced the death sentence to life imprisonment. Priyadarshini's father expressed disappointment with the CBI for failing to appeal against this decision.

Santosh Singh appealed against the death penalty sentence to the Supreme Court of India on 19 February 2007. The court also issued a notice to the Central Bureau of Investigation on an appeal filed by the convict against the high court's judgment. The defense lawyers of the accused Santosh Singh questioned the validity of the DNA report, one of the main causes for which he was given the benefit of doubt in the Trial court. Further the issue of Trial by Media is likely to be raised and whether excessive media coverage has influenced the verdict.

On 31 August 2006, six years after the initial appeal by CBI, justices RS Sodhi and PK Bhasin took up the case on a day-to-day hearing basis, which is extremely rare in India. Judgment was reached within 42 days which is quite unprecedented.

On 17 October 2006, Santosh Singh, who meanwhile had married and become a practising lawyer in Delhi itself, was found guilty under Indian Penal Code sections 302 (murder) and 376 (rape). The verdict blames G.P. Thareja's original judgment:

As recommended by the Central Bureau of Investigation the death penalty was awarded to Santosh Singh on 30 October 2006.

The acquittal of Santosh Singh in 1999 led to the investigating agency CBI, challenge the judgment in the Delhi high court on 29 February 2000.

Following a public outcry, the CBI then appealed the district court's verdict in Delhi High Court on 29 February 2000. Initially, the trial was not a priority, and there was no presentation of evidence or hearings in the Delhi High Court well into 2006. However, intense public scrutiny was mounted in the case after the acquittals in the Jessica Lal case, with Priyadarshini's aged father Chaman Lal Matoo making frequent appearances on TV, bringing the judiciary under intense pressure.

Delivering the ironical and widely criticized judgment in the trial court proceedings in 1999, the Additional Sessions Judge. G.P. Thareja said of Santosh, that though he knew that "he is the man who committed the crime," he was forced to acquit him, giving him the benefit of doubt.

Priyadarshini was in the third-year of her law program, when she was found strangled in her uncle’s residence. She had been raped, struck 14 times with a motorcycle helmet, and finally strangled with a wire. Santosh Kumar Singh, her senior in college, had been stalking and harassing her for several years, and was the immediate suspect. But Santosh came from an influential family - his father J.P. Singh was then Inspector General of Police in Pondicherry - in the course of the trial he served as Joint Commissioner of Police in Delhi, where the crime had been committed. In view of these connections, the court handed over investigation of the case to the Central Bureau of Investigation (CBI). In 1995, Priyadarshini had complained that Santosh Singh was harassing and stalking her. She had been provided with a personal security officer at the time. In retaliation, Santosh had lodged a complaint with the university alleging that she was pursuing two degrees simultaneously. However, it turned out that Priyadarshini had passed M.Com in 1991 and the complaint was merely malicious. On the morning of 23 January 1996, Santosh was seen knocking for entrance into Priyadarshini's uncle's house, where she was living, in the Vasant Kunj area of Delhi. A servant saw Santosh entering her house, apparently saying that he wanted a compromise in their legal complaints. Subsequently he raped her, strangled her with an electric wire and then battered her face beyond recognition with a motorcycle helmet. Santosh's presence in the house after the murder was also established by the prosecution.

Priyadarshini Mattoo (23 July 1970 – 23 January 1996) was a 25-year-old law student who was found raped and murdered at her house in New Delhi on 23 January 1996. On 17 October 2006, the Delhi High Court found Santosh Kumar Singh guilty on both counts of rape and murder and on 30 October of the same year sentenced him to death. On 6 October 2010, the Supreme Court of India commuted the death sentence to life imprisonment. Santosh Kumar Singh, the son of a Inspector-General of Police, had earlier been acquitted by a trial court in 1999, and the High Court decision was widely perceived in India as a landmark reversal. This decision was overturned as the facts were not presented correctly in the lower court.
