57. The apex Court, in order to put the Courts on firma terra, before grounding a conviction on a retracted confessional statement, evolved a six parameter test in gauging the veracity and truthfulness of such confessional statements. His Lordship, Adekeye, J.S.C. in Haruna v. Attor. Gen. Federation (2012) LPELR - 7821 (SC) at pages 28 - 29, succinctly stated that: "A Court can convict on the retracted confessional statement of an accused person but before this is properly done, the trial judge should evaluate the confession and the testimony of the accused person and all the evidence available. This entails the trial judge examining the new version of events presented by the accused person which is different from his retracted confession and the judge asking himself the following questions - Is there anything outside the confession to show that it is true? a. Is it corroborated? b. Are the relevant statements made in it of facts true as far as they can be tested? c. Did the accused person have the opportunity of committing the offence charged? d. Is the confession possible? e. Is the confession consistent with other parts which have been ascertained and have been proved? R. v. Sykes (1913) CAR pg. 113. R. v. Omokaro (1941) 7 WACA pg. 146. Achuba v. State (1976) NSCC pg. 74. Yusufu v. State (1976) 6 S.C. 167." Further see Afolabi v. The State (2013) 6 SCNJ (pt. 1) 159 at 192; Osetola v.
