But while in s. 74 (1) "expressly" cannot be understood as excluding enactments by implication, the distinction is not to be overlooked between a mere inference from an enactment and the enactment itself. It is a distinction that was made by Lord Denman C.J. in the case of Reg. v. St. Edmunds, Salisbury [4] when he said: "While we hold that a positive enactment is not to be repealed by inference we must also act on the maxim, " Leges posteriores priores contrarias abrogant " wherever it comes into operation" [5] . The contrast is between, on the one hand, a conclusion from what has been enacted that a further provision is a logical next step, the legislature not having taken that next step for itself, and, on the other hand, a conclusion that a provision which has been made means more than it explicitly says. "An implication is included in and part of that which is expressed: an inference is something additional to what is stated": Lubrano v. Gollin & Co. Pty. Ltd. [6] . Thus, while an exception from the operation of a statutory provision may be effected by an inconsistent implication in a later provision (or, with the aid of such exceptive words as those of s. 74 (1), by such an implication in an earlier enactment), it cannot result from an enactment which is not inconsistent in meaning and therefore in operation, even though the latter enactment provide ground for a conclusion that the draftsman's train of thought, if logically pursued, would have led him to enact the exception. Explicit or implicit contradiction is efficacious; merely "inferential contradiction", as Lord Hatherley called it in Attorney-General v. Great Eastern Railway Co. [7] , is not. The general provision of s. 74 (1) of the Justices Act is accordingly prefaced by words which have a saving effect as regards earlier enactments and serve as a reminder in relation to later, meaning in regard to both that the general provision which follows is not to be denied any of its operation save by something actually inconsistent with it in the operation of another enactment.
