France has voted down the proposed constitution of the European Union, a document designed to further unify the 25 member nations. In a national referendum on Sunday, those voting against the constitution prevailed by about 55 to 45 percent. Treaty opponents celebrated in Place de la Bastille, a major Paris landmark of the 1789 French revolution. The defeat in France casts the future course of the EU in some doubt. Each of the 25 countries had to ratify the new constitution before it could take effect. French President Jacques Chirac, in a broadcast address, said the EU will continue working on the basis of treaties currently in effect. He ignored calls for his resignation from opposition politicians.
