Book excerpt: Value Change in the Supreme Court of Canada is a groundbreaking analysis of the degree to which Supreme Court decisions reflect the changing values of society over the past four decades. Focusing on three key areas of law: environmental disputes, free speech, and discrimination cases, Wetstein and Ostberg provide a revealing analysis of the language used by Supreme Court justices in landmark rulings in order to document the way that value changes are transmitted into the legal and political landscape. Bolstered by a comprehensive and nuanced blend of research methods, Value Change in the Supreme Court of Canada offers a sweeping analysis of pre- and post-Charter influences, one that will be of significant interest to political scientists, lawyers, journalists, and anyone interested in the increasingly powerful role of the Supreme Court.
