Zahiruddin v.Emperor.

Hon’ble Privy Council observed about section 162 CrPC as, “... the effect of a contravention of the section depends on the prohibition which has been contravened. If the contravention consists in the signing of a statement made to the police and reduced into writing, the evidence of the witness who signed it does not become inadmissible. There are no words either in the section or elsewhere in the statute which express or imply such a consequence. Still less can it be said that the statute has the effect of vitiating the whole proceedings when evidence is given by a witness who has signed such a statement. But the value of his evidence may be seriously impaired as a consequence of the contravention of this statutory safeguard against improper practices.”
