HOST OF WITNESSES IS NOT NEEDED FOR SUCCEEDING

WHO IS A TAINTED WITNESS?

However, and for whatever it is worth, the law is settled that a tainted witness is a person who is either an accomplice or who on the evidence may be regarded as having some purpose of his/her own to serve – see R vs Enahoro (1964) NMLR 65; Ifejirika vs The State (1999) 3 NWLR (pt. 593) 59; Ogunlana vs The State (1995) 5 NWLR (Pt. 395) 266.

PROSECUTION MUST NOT CALL ALL WITNESSES, SUFFICIENT WITNESSES ARE ENOUGH

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.”

PROSECUTION ONLY OBLIGED TO CALL VITAL WITNESS

No doubt, the prosecution is only obliged to call witnesses whose evidence is vital to the determination of the case for the prosecution and whose evidence would settle vital points of facts one way or the other to remove any element of doubt in respect of the guilt of the Defendant from the case of the prosecution.

– H.M. Ogunwumiju, JSC. State v. Ibrahim (2021) – SC.200/2016

A CASE IS PROVED BY THE QUALITY OF WITNESSES, NOT QUANTITY

As the Supreme Court per Tobi, JSC puts it in Nigerian Army v. Major Jacob Iyela [2008] LPELR-2014 (SC); [2008] 7-12 SC 35; [2008] 18 NWLR (Pt. 1118) 115: A case is not necessarily proved by the quantity of witnesses. A case is proved by the quality of the witnesses in the light of either inculpatory or exculpatory evidence, as the case may be. And so, it does not necessarily follow that because the respondent called four witnesses, they rebutted the evidence of the two witnesses of the appellant.

WHETHER OR NOT A WITNESS IS AN ACCOMPLICE IS ONE OF LAW

The question whether or not a witness is an accomplice is one of law not of fact and if, as here, the learned trial Judge erred in regarding P.W.(18) as an accomplice (to the crime of conspiracy) it is certainly open to an appellate court (and in this instance, the Federal Court of Appeal) to reverse the erroneous view of the learned trial Judge.

— Idigbe, JSC. Ishola v State (1978) – SC.8/1977

PROSECUTION HAS DISCRETION TO CALL ITS IMPORTANT WITNESSES

It is trite law that there is no rule which imposes an obligation on the prosecution to call a host of witnesses; all the prosecution need do is to call enough material witnesses to prove its case, and in so doing it has a discretion in the matter. See: Samuel Adaje v. The State (1979) 6-9 SC 18 at 28. Bako Bahor v. Yaburi NA Police (1970) NMLR 107 at 112; E.O. Okonofua & Anor v. The State (1981) 6-7 SC 1 at 18. See also section 179(1) of the Evidence Act. What is more it is the law that if a witness is not called by the prosecution, the defence is at liberty to do so. —
