Book excerpt: This two-volume set examines the origins and growth of judicial review in the key G-20 constitutional democracies, which include the United States, the United Kingdom, France, Germany, Japan, Italy, India, Canada, Australia, South Korea, Brazil, South Africa, Indonesia, Mexico, and the European Union, as well as Israel. The volumes consider five different theories, which help to explain the origins of judicial review, and identify which theories apply best in the various countries discussed. They consider not only what gives rise to judicial review originally, but also what causes of judicial review lead it to become more powerful and prominent over time. Volume Two discusses the G-20 civil law countries.
