<P> The typography of the physical document pictured here, and still distributed today, was typeset by Ottawa's David Berman intentionally in Carl Dair's Cartier typeface: at the time the most prominent Canadian typeface, having been commissioned by the Governor - General as a celebration of Canada's centenary in 1967 . </P> <P> The Charter has been amended since its enactment . Section 25 was amended in 1983 to explicitly recognize more rights regarding Aboriginal land claims, and section 16.1 was added in 1993 . There have also been a number of unsuccessful attempts to amend the Charter, including the failed Charlottetown Accord of 1992 . The Charlottetown Accord would have specifically required the Charter to be interpreted in a manner respectful of Quebec's distinct society, and would have added further statements to the Constitution Act, 1867 regarding racial and sexual equality and collective rights, and about minority language communities . Though the Accord was negotiated among many interest groups, the resulting provisions were so vague that Trudeau, then out of office, feared they would actually conflict with and undermine the Charter's individual rights . He felt judicial review of the rights might be undermined if courts had to favour the policies of provincial governments, as governments would be given responsibility over linguistic minorities . Trudeau thus played a prominent role in leading the popular opposition to the Accord . </P> <P> The task of interpreting and enforcing the Charter falls to the courts, with the Supreme Court of Canada being the ultimate authority on the matter . </P> <P> With the Charter's supremacy confirmed by section 52 of the Constitution Act, 1982, the courts continued their practice of striking down unconstitutional statutes or parts of statutes as they had with earlier case law regarding federalism . However, under section 24 of the Charter, courts also gained new powers to enforce creative remedies and exclude more evidence in trials . Courts have since made many important decisions, including R. v. Morgentaler (1988), which struck down Canada's abortion law, and Vriend v. Alberta (1998), in which the Supreme Court found the province's exclusion of homosexuals from protection against discrimination violated section 15 . In the latter case, the Court then read the protection into the law . </P>
