It is no longer customary to the extent that it formerly was to maintain that judicial review of legislation and the consequent annulment of laws is an exclusively American political practice. With the courts of at least a score of countries passing on the validity of legislative acts, and occasionally refusing to apply them in concrete cases, the American method of guarding constitutions, characterized in the eighteenth and nineteenth centuries as a new political phenomenon, has now an extensive application among the countries operating under written fundamental laws.Interesting developments are taking place with respect to judicial review of legislation in foreign countries. Austria and Czechoslovakia have established special constitutional courts with authority to determine whether acts are in accord with their constitutions. Germany is in the process of adopting judicial review of acts of the national government as implied in the provisions of the new constitution. According to certain jurists, French courts have taken the first steps to establish themselves as the special interpreters and guardians of the French constitution. Though the dominant opinion of French lawyers and statesmen is opposed to judicial review as a feature of the French system of government, there is a growing sentiment in favor of the acceptance of the principle, as a necessary means of rendering more effective the provisions of the constitution and of protecting individual rights as guaranteed in the Declaration of Rights. The Irish Free State has followed the lead of Canada and Australia in placing the guardianship of its new constitution in the courts. In adopting a new constitution, Chile appears to have taken preliminary steps to change a system of parliamentary supremacy to a modified régime of judicial supremacy. There is considerable public discussion in Switzerland of the possibility of accepting the principle of review of the acts of the Federal Assembly.
