In Alonge v. I.G.P. (1959) 4 FSC 203 at 204; (1959) SCNLR 516, Ademola, CJF stressing the burden of proof on the prosecution in a criminal case observed: “Now, the commission of a crime by a party must be proved beyond reasonable doubt. The burden of proving that any person is guilty of a crime rests on the person who asserts it and this is the law as laid down in section 137 of the Evidence Ordinance. Cap. 62. The burden of proof lies on the prosecution and it never shifts; and if on the whole evidence the court is left in a state of doubt, the prosecution would have failed to discharge the onus of proof which the law lays upon it and the prisoner is entitled to an acquittal”
WHERE ACCUSED PLEADS GUILTY PROSECUTION BURDEN BECOMES LIGHT
OMOJU v. FRN (2008) LPELR – 2647 (SC), Tobi JSC (of blessed memory), considered the effect of an accused person’s plea of guilt on the burden placed on the prosecution where my noble Lord held thus: “The law is elementary that if an accused person pleads guilty, the burden of proof placed on the prosecution becomes light, like a feather of an ostrich. It no longer remains the superlative and compelling burden of proof beyond reasonable doubt. After all, the guilty plea has considerably shortened the distance and brought in some proximity the offence and mens rea or actus reus of the accused as the case may be. That makes it easier to locate causation or causa sine qua non.”
