A prosecutrix of a sex offence cannot be put on a par with an accomplice. She is in fact a victim of the crime.
The Evidence Act nowhere says that her evidence cannot be accepted unless it is corroborated in material particulars. She is undoubtedly a competent witness under Section 118 and her evidence must receive the same weight as is attached to an injured in cases of physical violence. The same degree of care and caution must attach in the evaluation of her evidence as in the case of an injured complainant or witness and no more.
What is necessary is that the court must be alive to and conscious of the fact that it is dealing with the evidence of a person who is interested in the outcome of the charge levelled by her. If the court keeps this in mind and feels satisfied that it can act on the evidence of the prosecutrix, there is no rule of law or practice incorporated in the Evidence Act similar to Illustration (b) to Section 114 which requires it to look for corroboration.
If for some reason the court is hesitant to place implicit reliance on the testimony of the prosecutrix it may look for evidence which may lend assurance to her testimony short of corroboration required in the case of an accomplice. The nature of evidence required to lend assurance to the testimony of the prosecutrix must necessarily depend on the facts and circumstances of each case. But if a prosecutrix is an adult and of full understanding the court is entitled to base a conviction on her evidence unless the same is shown to be infirm and not trustworthy.
If the totality of the circumstances appearing on the record of the case discloses that the prosecutrix does not have a strong motive to falsely involve the person charged, the court should ordinarily have no hesitation in accepting her evidence.
