This chapter examines the two models of judicial review that exist in the common law countries: the Diffuse Model and the Second Look Model. The Diffuse Model of judicial review originated in the United States and has spread to India, Canada, Australia, the United Kingdom, most of the countries of Latin America, the Scandinavian countries (except for the Netherlands), and Japan. It is premised on the idea that a country’s written constitution is its supreme law and that courts, when deciding cases or controversies that are properly before them, are thus duty-bound to follow the constitution, which is supreme law, and not a contrary statute whenever those two items conflict. Meanwhile, the essence of the Second Look Model of judicial review is that a Supreme or Constitutional Court ought to have the power of judicial review, subject to some kind of legislative power of override. This, it is said, best harmonizes the advantages of a written constitution and a bill of rights enforced by courts with the imperatives of democratic self-government. The underlying goal is to obtain the advantages of both constitutional government and also of democratic government.
