However, the Supreme Court of Canada has found that this list is not intended to be exhaustive, and in 1998's Reference re Secession of Quebec identified four "supporting principles and rules" that are included as unwritten elements of the constitution: federalism, democracy, constitutionalism and the rule of law, and respect for minorities.
然而，加拿大最高法院已决定此附表并没有包括全部的意图，及在1998年的魁北克分离参照中列出四项「辅助原则及规条」，包括不成文宪法元素: 联邦制、民主、宪制、法治、及尊重少数族裔。
