17. Hence, in order to pass the test of reliability, a dying declaration has to be subjected to a very close scrutiny, keeping in view the fact that the statement has been made in the absence of the accused who had no opportunity of testing the veracity of the statement by cross-examination. But once, the court has come to the conclusion that the dying declaration was the truthful version as to the circumstances of the death and the assailants of the victim, there is no question of further corroboration. If, on the other hand, the court, after examining the dying declaration in all its aspects, and testing its veracity, has come to the conclusion that it is not reliable by itself, and that it suffers from an infirmity, then, without corroboration it cannot form the basis of a conviction. Thus, the necessity for corroboration arises not from any inherent weakness of a dying declaration as a piece of evidence, as held in some of the reported cases, but from the fact that the court, in a given case, has come to the conclusion that that particular dying declaration was not free from the infirmities referred to above or from such other infirmities as may be disclosed in evidence in that case.”
