Written answers of questions can not be sought in form of confession.

Section 160 CRPC only empowers investigating officer to send a notice to a person, who is acquainted with the crime, in order to ensure his or her attendance in the police station or in the case of a female at any other place of her own choice. Written answers of questions can not be sought in form of confession. In Nandini Satpathi versus PL Dani 1978 the honorable supreme court clearly held that seeking such confessional answers of questions in written form will amount to self incrimination and it is violation of fundamental right.Any mode of pressure, subtle or crude, mental or physical, direct or indirect, but sufficiently substantial applied by the police to obtain information from the accused, strongly suggestive of guilt, is compulsion. Police can prepare only interrogation note in his own writing and that memo has no relavancy and admissibility.
