WHERE ACCUSED PERSON IS THE ONLY WITNESS TO AN EVENT

WHO IS A TAINTED WITNESS

A tainted witness falls into one or both of the two categories hereunder listed: (1) A witness who is an accomplice in the crime charged. (2) A witness who, by the evidence he gives, may and could be regarded as having some purpose of his own to serve. Rasheed Olaiya v. The State (2010) Vol. 180 LRCN 1-197 p.34; The State v. Dominic Okoro & Ors (1974) 2 SC 73 at 82; Ishola v. The State (1978) 9-10 SC 73 at 100 .

QUALITY OF TESTIMONY OF WITNESSES

The trial court does not come to a decision by the quantity of the witnesses but on the quality or probative value of the testimony of the witnesses. — O.O. Adekeye, JSC. Mini Lodge v. Ngei (2009) – SC.231/2006

RELATIONSHIP BY BLOOD CANNOT DISQUALIFY A WITNESS AS BEING A TAINTED WITNESS

The fact that he (PW 4) is a brother to the deceased with but more, cannot in my view make or turn him into a tainted or biased witness. He was not shown to have been an accomplice in the commission of the offence nor that he had any interest or purpose of his own to serve as such witness. Relationship by blood without any more cannot tantamount to a disqualification from being a prosecution witness, and I am not aware of any of our laws which provide as such. Consequently, the evidence of PW 4 in my view requires no corroboration. Ishola v. The State (1978) 9 & 10 SC81; Onafowokan v. The State (1986) 2 NWLR (Pt. 23) 496; Arehia & Anor v. The State (1982) 4SC7 8; Hausa v. The State (1992) 1 NWLR (Pc 219) 600.

COURT OF LAW CAN CONVICT ON THE EVIDENCE OF ONE WITNESS

Accordingly, in arriving at a conviction in criminal cases, the court is concerned with whether or not there is sufficient credible evidence of probative value and not the number of witnesses called on an issue. See: Commissioner of Police v. Daniel Kwashie (1953) 14 WACA 319. Where a single witness called by the prosecution is neither an accomplice nor a tainted witness, a court of law is entitled to convict mainly on his credible evidence where his testimony did not by law require corroboration. Once the court is satisfied with the cogency, high quality and credibility of the evidence of a witness and accepts it, conviction based on such evidence should not be interfered with unless such evidence by law requires corroboration. So, in the Daniel Kwashie case, the learned magistrate convicted the appellant on the evidence of one witness. On appeal to the High Court, the learned Judge found that although, corroboration was not required by law, a court was generally reluctant to convict on the evidence of a single witness and proceeded to allow the appeal. On further appeal to the West African Court of Appeal, the appellate judge was reversed and his decision was set aside on the ground that there was sufficient evidence before the learned magistrate on which he based his conviction. It was further held that since the learned magistrate believed the witness and there was no imputation that the sole witness was an accomplice or a tainted witness, it was an error to reverse his decision and the conviction was restored.

NO OBLIGATION TO CALL A HOST OF WITNESSES BY THE PROSECUTION

Okonofua & Anor v. The State (1981) 6-7 SC 1 at 18 where this court per Bello, J.S.C., as he then was, dealing with the same subject put the matter thus:- “The correct state of the law relating to the duty of the prosecution to call witnesses, whether their names appear on the back of the information or not, has been recently stated by this court in these terms: ‘The law imposes no obligation on the prosecution to call a host of witnesses. All the prosecution need do is to call enough material witnesses in order to prove its case; and in so doing, it has a discretion in the matter.’ ” See also Samuel Adaje v. The State (1979) 6-9 SC 18 at 28.
