This book puts similar claims to test in relation to highest national jurisdictions (supreme and constitutional courts) in Europe today. How often and why do judges choose to draw inspiration from foreign materials in solving domestic cases? The book addresses these questions from both an empirical
and a theoretical angle. Empirically, the genuine use of comparative arguments by national highest courts in five European jurisdictions is examined: England and Wales, France, Germany, the Czech Republic, and Slovakia. On the basis of comparative discussion of the practice and its national
theoretical underpinning in these and partially also in other European systems, an overreaching theoretical framework for the current judicial use of comparative arguments is developed.

Drawing on the author's own past judicial experience in a national supreme court, this book is a critical account of judicial engagement with foreign authority in Europe today. The sober middle ground inductively conceptualized and presented in this book provides solid jurisprudential foundations
for the ongoing use of comparative arguments by courts as well as its further scholarly discussion.
