minority can secede. In the United States Abraham Lincoln acknowledged that secession might be possible through amending the United States Constitution. The Supreme Court in Texas v. White held secession could occur "through revolution, or through consent of the States." The British Parliament in 1933 held that Western Australia only could secede from Australia upon vote of a majority of the country as a whole; the previous two-thirds majority vote for secession via referendum in Western Australia was insufficient. The Chinese Communist Party followed the Soviet Union in including the right of secession in its 1931 constitution in order to entice ethnic nationalities and Tibet into joining. However, the Party eliminated the right to secession in later years, and had anti-secession clause written into the Constitution before and after the founding the People's Republic of China. The 1947 Constitution of the Union of Burma contained an express state right to secede from the union under a number of procedural conditions. It was eliminated in the 1974 constitution of the Socialist Republic of the Union of Burma (officially the "Union of Myanmar"). Burma still allows "local autonomy under central leadership". As of 1996 the constitutions of Austria, Ethiopia, France, and Saint Kitts and Nevis have express or implied rights to secession. Switzerland allows for the secession from current and the creation of new cantons. In the case of proposed Quebec separation from Canada the Supreme Court of Canada in 1998 ruled that only both a clear majority of the province and a constitutional amendment confirmed by all participants in the Canadian federation could allow secession. The 2003 draft of the European Union Constitution allowed for the voluntary withdrawal of member states from the union, although the State which wanted to leave could not be involved in the vote deciding whether or not they can leave the Union. There was much discussion about such self-determination by minorities before the final document underwent the unsuccessful ratification process in 2005. As a result of the successful constitutional referendum held in 2003, every municipality in the Principality of Liechtenstein has the right to secede from the Principality by a vote of a majority of the citizens residing in this municipality. Drawing new borders In determining international borders between sovereign states, self-determination has yielded to a number of other principles. Once groups exercise self-determination through secession, the issue of the proposed borders may prove more controversial
