It offers a well-informed and insightful description and explanation of the so-called Lex Olympica. The book analyses the legal and institutional aspects that arise in the Olympic Movement, like its definition, composition and general organisation, its three principal constituents, its three ‘Satellite Organisations’ and its organs.
