It is an important issue to consider under the proposed 21st Amendment to the Constitution whether the President should sign, ratify or accede to treaties in consultation with the Prime Minister. In this article, it is proposed to provide an analysis of this important issue by reference to current constitutional law and practices of Commonwealth countries.
Before I deal with this issue, it is useful to outline the importance of treaties as outlined in the following references: (Richard Ware, “Parliament and Treaties” in Parliament and International Relations, (1991), pp.37-48; Lord McNair, Law of Treaties, (1961), pp.83-94; Sir Kenneth Keith, ‘New Zealand Treaty Practice: The Executive and the Legislature’ (1964), 1 N.Z.L.R., pp.277-281.
