Confession was not given by the evidence act of 1967, but it has been defined in case laws. Before 1980, confession has been defined in the case of R v. Bampamiyki (1957) EA 473 it was held that the statement should be regarded as a confession only when it contains ingredients of the crime with which the accused person is charged, so that the accused person could be properly convicted on his own plea. Also in the case of Ali v. R (1971) EA 75 confession is made spontaneously which contain every ingredient of the offence which is subsequently charged..it points clearly to the guilt of the maker.

R (1987) TLR 297in this case the issue was whether a confession made to a police officer is admissible evidence, and what was the effect of the 1980 amendment to section 27 of the evidence act. It was held that the effect of the amendment to section 27 of the evidence act of 1967 was to make confessions voluntarily made to a p
