Book excerpt: This book provides a comprehensive exploration of ideological patterns of judicial behaviour in the Supreme Court of Canada. Relying on an expansive database of Canadian Supreme Court rulings between 1984 and 2003, the authors present the most systematic discussion of the attitudinal model of decision making ever conducted outside the setting of the US Supreme Court. They test the assumption, accepted by many political scientists, that conflict in the courts is due in large part to ideological divisions among the members. The groundbreaking discussion of the viability of the attitudinal model as a unifying theory of judicial behaviour in high courts around the world will be essential reading for a wide range of legal scholars and court watchers.
