Lord Hewart, Lord Chief Justice of England observed in P. L. Taylor & Ors. v. R. 21 Cr. App. R20 at p.21: It has been said that the evidence against the applicants is circumstantial: so it is but circumstantial evidence is very often the best. It is evidence of surrounding circumstances which, by undesigned coincidence is capable of proving a proposition with the accuracy of mathematics.
CIRCUMSTANTIAL PIECE OF EVIDENCE MUST BE COGENT, COMPLETE, UNEQUIVOCAL
Pius Nweke v. The State (2001) 84 LRCN 482 at 506, was held: “To secure a conviction in a criminal trial, circumstantial piece or pieces of evidence must be cogent, complete and unequivocal. Such evidence must be too compelling and must lead to the irresistible conclusion that the accused and no one else committed the crime. Indeed, the facts must be incompatible with the innocence of the accused and incapable of explanation upon any other hypothesis than that of his guilt.” See the decision of this Court in Joseph Lori v. The State (1990) 8-11 SC 86 at 87. See also Iyaro v. The State (1988) 1 NWLR (pt.69) 256; Mbenu v. The State (1988) 3 NWLR (pt. 84) 615 at 630; Ukorah v. The State (supra); Adie v. The State (1990) 1-2 SC 11 at 22.
