The court said the case rested mainly on the third dying declaration of the victim but its genuineness and veracity have not been proved by the prosecution due to the negligence and failure of the investigating officer.
"When the dying declaration of the prosecutrix has not been proved by the prosecution, the reason for her suicide i.e. rape by accused also remains unproved....
"The role of the accused in the suicide of the prosecutrix has not been proved by the prosecution," Additional Sessions Judge Nivedita Anil Sharma said.
The court acquitted Uttar Pradesh resident Venktanjaneya Partap Singh, saying no inference can be drawn that he was guilty of the charged offences as the testimony of the prosecution witnesses was unreliable and unworthy of credence.
According to the prosecution, sometime during the period of four years prior to February 23, 2011, Singh had raped the victim at his house in Rajouri Garden here.
Singh and the girl were working in the same office and he established physical relations with her on the pretext of marrying her, it said, adding that later on the girl came to know that the youth was getting married to someone else.
When she confronted him, he first denied but later on accepted that he was getting married to someone else and instigated and abetted her to commit suicide, it said.
She attempted suicide first by drinking acid and then pouring petrol on her and setting herself on fire in her house. She died on March 3, 2011.
The girl in her first two statements had not blamed the youth for the extreme step of ending her life but in her third dying declaration, she had given the details that he had raped her and abetted her suicide.
The court, however, said the evidence indicated that the third dying declaration was false and fabricated.
It said the version of the prosecution appeared to be unreliable and untrustworthy and it was required that the case should have been investigated with great responsibility and sincerity.
"It appears that a very casual approach rather a negligent approach has been taken by the IO for investigation in this case which was required to be investigated with great responsibility and sincerity," it said.
The judge said considering the fact that "IO SI Ashok Kumar has not conducted the investigation properly and his conduct is deplorable, copies of this judgement be sent to the DCP, West and the Commissioner of Police for information and to ensure that no such lapses are committed by any investigating officer in future".
Singh, in his defence, had said that he and the girl were good friends and they used to go for outing along with other friends. He came to know that she used to like him but her parents objected to it due to which he ended her life.
