The Respondent subsequently retracted Exhibits C & C 1. A retracted confessional statement is nonetheless admissible in evidence. The practice however is to look for some corroborative evidence outside the confession which makes the fact of the making of the confession credible and reliable before the Court relies on it to convict the accused, the maker. This practice which has come to be known as the “SYKE’S RULE”, following R. v. SYKES (1913) 8 Cr. App Report 233, has since become part of our criminal law jurisprudence, it having been cited with approval in several cases including UBIERHO v. THE STATE (2005) 5 NWLR (pt. 919) 644; FABIYI v. THE STATE (2015) LPELR 24834 (SC). The Rule ensures that the trial Court must properly satisfy itself that the retracted confession was infact made truly and voluntarily by the accused person.
