The third volume of the Vienna Lectures on Legal Philosophy series focuses on one of the most fiercely contested issues in contemporary legal philosophy: the question of the importance of legal reasoning and how to properly engage with it. This book considers legal reasoning from two different angles: it revolves, on the one hand, around debates concerning interpretation and balancing, but it also asks, on the other, whom we ought to entrust with decision-making based on legal reasoning and how this relates to the very concept of law. The book approaches these underlying problems from a variety of perspectives and against the backdrop of different academic traditions, showcasing the rich landscape of critical debates around contemporary legal reasoning.

This second volume of the Vienna Lectures on Legal Philosophy series presents 11 chapters which are dedicated to normativist and anti-normativist approaches to law. The book focuses on the question: What is law? Is it a set of obligations imposed on courts and officials to guide their conduct and to assess the conduct of others? Or is it the result of settlements reached by opposing sides that accept arrangements and understandings to sustain peaceful cooperation? If law is the former its significance and meaning are independent of a shifting constellation of forces; if it is not, then what the law says depends on the relative power and prestige of the actors involved. With contributions from some of the leading scholars in the field, the collection presents a balanced and nuanced assessment of what is perhaps the most controversial debate in contemporary legal philosophy today.

The first volume of the Vienna Lectures on Legal Philosophy illustrates the remarkable scope of contemporary legal philosophy. It introduces methodological questions rooted in national academic discourses, discusses the origin of legal systems, and contrasts constitutionalist and monist approaches to the rule of law with the institutionalist approach most prominently and vigorously defended by Carl Schmitt. The issue at the core of these topics is which of these perspectives is more plausible in an age defined both by a 'postnational constellation' and the re-emergence of nationalist tendencies; an age in which the law increasingly cancels out borders only to see new frontiers erected.

This is the first part of a 2-volume set that presents an in-depth investigation into the canon of constitutionally conforming interpretation. These volumes address the fundamental issues the canon raises in the national, supranational and international contexts. In volume 1, experts from 19 jurisdictions, including Brazil, Canada, India, the UK, and the USA, present reports which give concise overviews of the approaches and debates on constitutionally conforming interpretation. These reports cover the structural background, the conditions of application, as well as issues of competence. Further aspects discussed are its perceived normativity and popularity in everyday legal practice. Together with volume 2, which explores the canon's use and theoretical impact beyond the national context in a comparative and critical manner, this book fills an important gap in legal scholarship and sets the stage for cross-national discourse.

Emergency Powers of International Organizations explores emergency politics of international organizations (IOs). It studies cases in which, based on justifications of exceptional necessity, IOs expand their authority, increase executive discretion, and interfere with the rights of their rule-addressees. This ''IO exceptionalism'' is observable in crisis responses of a diverse set of institutions including the United Nations Security Council, the European Union, and the World Health Organization. Through six in-depth case studies, the book analyzes the institutional dynamics unfolding in the wake of the assumption of emergency powers by IOs. Sometimes, the exceptional competencies become normalized in the IOs' authority structures (the ''ratchet effect"). In other cases, IO emergency powers provoke a backlash that eventually reverses or contains the expansions of authority (the "rollback effect"). To explain these variable outcomes, this book draws on sociological institutionalism to develop a proportionality theory of IO emergency powers. It contends that ratchets and rollbacks are a function of actors' ability to justify or contest emergency powers as (dis)proportionate. The claim that the distribution of rhetorical power is decisive for the institutional outcome is tested against alternative rational institutionalist explanations that focus on institutional design and the distribution of institutional power among states. The proportionality theory holds across the cases studied in this book and clearly outcompetes the alternative accounts. Against the background of the empirical analysis, the book moreover provides a critical normative reflection on the (anti) constitutional effects of IO exceptionalism and highlights a potential connection between authoritarian traits in global governance and the system's current legitimacy crisis.

A Treatise of Legal Philosophy and General Jurisprudence is the first-ever multivolume treatment of the issues in legal philosophy and general jurisprudence, from both a theoretical and a historical perspective. The work is aimed at jurists as well as legal and practical philosophers. Edited by the renowned theorist Enrico Pattaro and his team, this book is a classical reference work that would be of great interest to legal and practical philosophers as well as to jurists and legal scholar at all levels. The work is divided in two parts. The theoretical part (published in 2005), consisting of five volumes, covers the main topics of the contemporary debate; the historical part, consisting of six volumes (Volumes 6-8 published in 2007; Volumes 9 and 10, published in 2009; Volume 11 published in 2011 and Volume 12 forthcoming in 2016), accounts for the development of legal thought from ancient Greek times through the twentieth century. Volume 12 Legal Philosophy in the Twentieth Century: The Civil Law World Volume 12 of A Treatise of Legal Philosophy and General Jurisprudence, titled Legal Philosophy in the Twentieth Century: The Civil-Law World, functions as a complement to Gerald Postema’s volume 11 (titled Legal Philosophy in the Twentieth Century: The Common Law World), and it offers the first comprehensive account of the complex development that legal philosophy has undergone in continental Europe and Latin America since 1900. In this volume, leading international scholars from the different language areas making up the civil-law world give an account of the way legal philosophy has evolved in these areas in the 20th century, the outcome being an overall mosaic of civil-law legal philosophy in this arc of time. Further, specialists in the field describe the development that legal philosophy has undergone in the 20th century by focusing on three of its main subjects—namely, legal positivism, natural-law theory, and the theory of legal reasoning—and discussing the different conceptions that have been put forward under these labels. The layout of the volume is meant to frame historical analysis with a view to the contemporary theoretical debate, thus completing the Treatise in keeping with its overall methodological aim, namely, that of combining history and theory as a necessary means by which to provide a comprehensive account of jurisprudential thinking.
