Book excerpt: This book takes a close look at the Court of Arbitration for Sport (CAS), challenging existing claims and answering previously unanswered questions, by considering all of its publicly available decisions, both in its entirety as a body of jurisprudence and on a case-by-case level. It also investigates the actors involved in adjudication before the CAS, both the parties that bring disputes before the CAS and the arbitrators that resolve them, and in so doing establish precedents that govern sports generally. While the book relies upon and includes more traditional legal theory and analysis, it combines this with an empirical analysis of a large portion of the CAS's decisions. Hereby it relies upon and relates to the theory of the development of a transnational legal order in sports, the lex sportiva. The publication is targeted at and will benefit those professionally working in or interested in the fields of sports law, arbitration law, transnational law, or empirical legal studies. Johan Lindholm is a Professor of Law at Umeå University in Sweden.
