In R v. Teper (1952) AC 480 at 489, it was held: “Circumstantial evidence may sometimes be conclusive, but it must always be narrowly examined, if only because evidence of this kind may be fabricated to cast suspicion on another… It is also necessary before drawing the inference of the accused guilt from circumstantial evidence to be sure that there are no other co-existing circumstances which would weaken or destroy the inference.”
CIRCUMSTANTIAL EVIDENCE IS OFTEN THE BEST FORM OF EVIDENCE
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.
