As noted in the Supreme Court case 'Reference re Bill 30, An Act to Amend the Education Act (Ont.)' 1 SCR 1148 (SCC), this clarification is really the only function of section 29. Section 29 does not itself shield the rights of denominational schools from the "Charter", since the rights are themselves a part of the Constitution and thus cannot be unconstitutional or subject to "Charter" review. This line of thinking was confirmed by the Supreme Court in "Gosselin (Tutor of) v. Quebec (Attorney General)" (2005).
