In OCHIBA v. THE STATE (2011) LPELR 8245 (SC) where it was held as follows: “I need to say it that it is settled Law that the prosecution was not obliged to call a host of witnesses in order to discharge the burden placed on it to prove the charge against the appellant beyond reasonable doubt as dictated by section 138(1) of the Evidence Act. A sole witness like P.w.1, who has given credible and clear evidence which was believed by the trial Judge, will suffice. See OBUE V THE STATE (1976) 2 SC 141; SADAM v THE STATE [2010] 12 SC (PT.1) 73 at 87-88; AKPAN v THE STATE [1991] 3 NWLR (PT 182) 695”.
THERE CAN BE CONVICTION BASED ON THE TESTIMONY OF A SOLE WITNESS
The law is trite that unless where the law prescribes otherwise, there can be a conviction based on the evidence of a sole witness. Such evidence of a sole witness must be cogent, strong, credible and reliable before a Court can rely to found a conviction. See Oduneye v The State (2001) 2 NWLR (pt 697) 311, Abogede v State (1996) 5 NWLR (pt 449) 279 at 280, Ighalo v The State (2016) LPELR – 40840 (SC). 27 Ordinarily, the credibility of evidence does not depend on the number of witnesses who testify on a particular issue, but it depends on whether the evidence of a single witness is believable and accepted by the Court and if so believed by the Court, then it is sufficient to ground a conviction. SeeAli v The State (1988) 1 NWLR (pt 68) 1, Lase v The State (2017) LPELR – 42468 (SC), Abogede v The State (1996) 4 SCNJ 227.
