Switzerland is not only one of the oldest democracies in the world, but also an enduring model of peaceful multiethnic policy, characterized by a Constitution that is constant flux. The new Federal Constitution of the Swiss Confederation took effect on January 1, 2000; and it is with the intention of staying abreast of the constitutional changes and of the case law of the Federal Court that the authors have prepared the current volume.
