relied upon unless corroborated by some other credible evidence. The courts have considered the evidence of extra-judicial confession a weak piece of evidence. See Jagta v. State of Haryana and State of Punjab v. Bhajan Singh and Ors. In Sahoo v. State of U.P, it was held that 'an extra-judicial confession may be an expression of conflict of emotion, a conscious effort to stifle the pricked conscience; an argument to find excuse or justification for his act; or a penitent or remorseful act of exaggeration of his part in the crime.' Before evidence in this behalf is accepted, it must be established by cogent evidence what were the exact words used by the accused. The Court proceeded to state that even if so much was established, prudence and justice demand that such evidence cannot be made the sole ground of conviction. It may be used only as a corroborative piece of evidence. In that case, the evidence was that after the commission of murder the accused was heard muttering to himself that he has finished the deceased. The High Court did not interfere with the conviction observing that the evidence of extrajudicial confession is corroborated by circumstantial evidence. However, in Pyara Singh v. State of Punjab (1978) 1 SCR 661, this Court observed that the law does not require that evidence of an extra-judicial confession should in all cases be corroborated. It thus appears that extra-judicial confession appears to have been treated as a weak piece of evidence but there is no rule of law nor rule of prudence that it cannot be acted upon unless corroborated. If the evidence about extra-judicial confession comes from the mouth of witness/witnesses who appear to be unbiased, not even remotely inimical to the accused, and in respect of whom nothing is brought out which may tend to indicate that he may have a motive for attributing an untruthful statement to the accused; the words spoken to by the witness are clear, unambiguous and unmistakably convey that the accused is the perpetrator of the crime and nothing is omitted by the witness which may militate against it, then after subjecting the evidence of the witness to a rigorous test
