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.
PROSECUTION OWES NOT THE COURT A DUTY TO CALL HOST OF WITNESSES
The prosecution does not have the obligation to put forward two versions of one incident. See ONUBOGU v. THE STATE (supra); BOY MUKA v. THE STATE (supra); ALFRED ONYEMENA v. THE STATE (1974) ALL NLR 522. Once the prosecution can prove their allegation beyond reasonable doubt with the witnesses they have screened and selected, they would have discharged the burden of proof cast on them by law. They owe neither the Court nor the accused the duty to call a host of witnesses, or a particular witness.
