Hardcover, ix + 310 pages, NOT ex-library. Minor handling wear, book is clean and bright throughout, with unmarked text, free of inscriptions and stamps, firmly bound. Untorn, gently shelfworn dust jacket. -- This book offers a comprehensive, empirically grounded analysis of how and why the highest courts in select European legal systems (England and Wales, France, Germany, the Czech Republic, and Slovakia) make reference to foreign legal materials when resolving domestic cases. Focusing on non-mandatory uses of comparative reasoning - where judges choose, rather than are legally obliged, to cite foreign law - the book investigates the practical scope, frequency, and conceptual legitimacy of such references in supreme and constitutional court decisions. It begins by mapping the broader scholarly context, including widespread but largely untested claims about a rise in judicial transnational dialogue, and sets out to test these claims through a mix of qualitative and quantitative methods. The author identifies three general categories of foreign law use: mandatory (e.g. conflict of laws), advisable (e.g. shared legal traditions), and voluntary (non-binding, optional citation), with primary focus on the last two. The first part of the book lays a typological and theoretical groundwork, examining historical shifts in the openness of legal systems to foreign influence, and assessing the contextual, institutional, procedural, and personal factors that impact a court's willingness and ability to engage in comparative reasoning - such as size and age of the legal system, presence of analytical support staff, or costs of litigation. The second part presents detailed national case studies, each of which assesses doctrinal and methodological traditions, judicial attitudes, and patterns of comparative reference. For instance, the UK system demonstrates selective engagement with other common law jurisdictions; French courts show more implicit than explicit comparative references; German courts rely heavily on doctrinal scholarship; while in post-communist countries such as the Czech Republic and Slovakia, comparative citation emerged prominently after 1989 but has since become more constrained. These studies are based on original-language primary sources, interviews with judges, and the author’s insider access to judicial networks and materials. The third part of the book offers a positivistic theoretical appraisal, addressing questions such as when comparative reasoning is justified, how it is constrained by systemic norms (e.g. it can be persuasive but not binding), and what institutional or stylistic factors shape whether foreign law is openly cited or silently consulted. The author also revisits classic concerns such as the legitimacy, methodology, and predictability of comparative reasoning, showing how these concerns play out differently in Continental and common law traditions. The final chapter explores deviations from the norm, such as politically motivated overuse of foreign references during legal transitions (e.g. Central Europe) or conscious rejection of such reasoning (e.g. US debates). For academic researchers and legal professionals, this book provides a rare, structured, and data-informed resource for understanding the actual judicial practice of comparative reasoning across varied jurisdictions. It is especially relevant for scholars of comparative constitutional law, legal method, judicial behavior, or transnational legal theory, and can be used to design empirical or doctrinal studies, develop judicial training programs, or evaluate reform proposals. Its detailed typology and comparative framework also make it a valuable reference for judges and court advisors considering whether, when, and how to incorporate comparative legal arguments into domestic decision-making processes.…
