For the purpose of interpreting a treaty, the’context'of a treaty entails "in addition to the text, including its preamble and annexes": (i) any agreement or instrument in connection with the conclusion of the treaty and related to it (article 31(2) VCLT), (ii) any subsequent agreement and practice regarding the interpretation of the treaty (article 3i(3)(a)(b)), and (iii) any relevant rules of international law applicable in relations between the parties (article 3i(3)(c)). For example, in interpreting the Canadian Charter of Rights and Freedoms, the Canadian Supreme Court makes use of the ‘living tree doctrine'. As stated by Chief Justice Antonio Lamer in Re B.C. Motor Vehicle Act, "If the newly planted ‘living tree' which is the Charter is to have the possibility of growth and adjustment over time, care must be taken to ensure that historical materials, such as the Minutes of Proceedings and Evidence of the Special Joint Committee, do not stunt its growth".
