Secondly, it is a well established principle of law that it is not necessary for a person on whom the onus of proof lies, even in criminal cases, to call every available piece of evidence in order to discharge that burden. It is enough if evidence is tendered sufficient to discharge the onus which the law lays upon the prosecution. See: Francis Odili v. The State (1977) 4SC 1 or (1977) 11 NSCC 154 at 158 and Joshua Alonge v.I.G. of Police (1959) SCNLR 516; (1959) 4 FSC 203 or (1959) 1 NSCC 169. In the Francis Odili case, the appellant was convicted and sentenced to death. Following his arrest, the appellant was identified at an identification parade by one of the two Rev. Sisters they violently robbed with arms. At the trial, he pleaded alibi. The learned counsel contended inter alia that the evidence of identification was unreliable and that the prosecution failed to call two other eye witnesses to the incident. On appeal, this court per Alexander C.J.N. stated as follows:- “Counsel’s last submission was that the 2 night guards should have been called as witnesses as they were present throughout………………..The tribunal, in its judgment, pointed out that the defence had an equal opportunity to call the night guards if they considered that the evidence of the night, guards would be favourable to them. The tribunal found no merit in this submission and we unhesitatingly agree. The prosecution is not required to call very available piece of evidence to prove its case. It is enough if sufficient evidence is called to discharge the onus of proof beyond reasonable doubt.”
