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 EVIDENCE MUST BE CAPABLE OF PROVING A PROPOSITION WITH THE ACCURACY OF MATHEMATICS
Speaking of circumstantial evidence, Lord Heward, CJ, said, inter alia: “… 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. It is no derogation of evidence to say that it is circumstantial.” See R v. Taylor & Ors (1928) 21 CAR 20 at 21.
