In ASIMI V. STATE (2016) LPELR – 40436 (SC), this Court per Rhodes Vivour JSC at Pp 14-15, para E-C stated succinctly thus: 22 “Once, an extra-judicial confession has been proved as in this case to have been made voluntarily and it is positive and unequivocal, amounting to an admission of guilt (such as the appellant’s confessional statement, Exhibit P6) a Court can convict on it even if the appellant retracted or resiled from it at trial. Such an afterthought does not make the confession inadmissible. It is desirable but not mandatory that there is general corroboration of the important incidents and not that retracted confession should be corroborated in each material particular.”
TRIAL-WITHIN-TRIAL IS TO TEST VOLUNTARINESS OF CONFESSIONAL STATEMENTS ONLY
I agree with the learned counsel for the Respondent that the Appellant’s counsel had really misunderstood the fundamental requirement in criminal trial. A trial within trial is required in law where the objection to admissibility of a statement is based on the ground that it was not made voluntarily. In that case there has to be a trial within trial to determine the question of voluntariness. It is only where this is proved by the prosecution that the statement is admitted in evidence.
