Halpern et al. v. Attorney General of Canada et al. (June 10, 2003): �The British North America Act planted in Canada a living tree capable of growth and expansion within its natural limits.� "The task of expounding a constitution is crucially different from that of construing a statute. A statute defines present rights and obligations. It is easily enacted and as easily repealed. A constitution, by contrast, is drafted with an eye to the future. Its function is to provide a continuing framework for the legitimate exercise of governmental power and, when joined by a Bill or a Charter of Rights, for the unremitting protection of individual rights and liberties. Once enacted, its provisions cannot easily be repealed or amended. It must, therefore, be capable of growth and development over time to meet new social, political and historical realities often unimagined by its framers. The judiciary is the guardian of the constitution and must, in interpreting its provisions, bear these considerations in mind."
