Maxwell on Interpretation of Statutes 12th Ed. page 116. The statement of the law reads: “Few principles of statutory interpretation are applied as frequently as the presumption against alterations in the common law. It is presumed that the legislature does not intend to make any change in the existing law beyond that which is expressly stated in or followed by necessary implication from the language of the statute in question. It is thought to be in
the highest degree improbable that Parliament would depart from the general system of law
without expressing its intention with irresistible clearness and to give any such effect to general words merely because this would be their widest, usual, natural or literal meaning would be to place on them a construction other than that which Parliament must be supposed to have intended. If the arguments on a question of interpretation are fairly evenly balanced, that interpretation should be chosen which involves the least alteration of the existing law.”
