It must always be borne in mind and this is settled, that the burden of proving that any person is guilty of a crime, rests on the prosecution. The cardinal principle of law, is that the commission of a crime by a party must be proved beyond reasonable doubt. This is the law laid down in section 138(1) of the Evidence Act. The burden never shifts. Therefore, if on the whole of the evidence, the court is left in a state of doubt (as I am in this instant case leading to this appeal), the prosecution would have failed to discharge the onus of proof which the law lays upon it and the prisoner/accused person, is entitled to an acquittal. See the cases of Alonge v. Inspector-General of Police (1959) 4 FSC 203, (1959) SCNLR 516; Fatoyinbo v. Attorney-General, Western Nigeria (1966) WNLR 4, and The State v. Musa Danjuma (1997) 5 SCNJ 126 at 136-137, 156; (1997) 5 NWLR (Pt. 506) 512.
