"(1) If there is no evidence that the crime alleged has been committed by the defendant there is no difficulty - the judge will stop the case. (2) The difficulty arises where there is some evidence but it is of a tenuous character, for example, because of inherent weakness or vagueness or because it is inconsistent with other evidence.

(b) Where however the prosecution evidence is such that its strength or weakness depends on the view to be taken of a witness's reliability, or other matters which are generally speaking within the province of the jury and where on one possible view of the facts there is evidence on which the jury could properly come to the conclusion that the defendant is guilty, then the judge should allow the matter to be tried by the jury."
