Halsbury’s Laws of England, Volume 14 paragraphs 904 and 906, which read: “Except insofar as they are clearly and unambiguously intended to do so, statutes should not be construed so as to make any alteration in the common law or to change any established principle of law, or to alter completely the character of the principle of law contained in statutes which they merely amend. There is no presumption that by legislating Parliament intended to change the law. ” “Unless it is clearly and unambiguously intended to do so, a statute should not be construed so as to interfere with or prejudice established private rights under contracts or the title to property, or so as to deprive a man of his property without his having an opportunity of being heard.”
