In this book one of the longest-standing members of The Venice Commission reflects on the work of the institution to show how constitutional law in Europe (and beyond) has become increasingly borderless. Over nine chapters, the book tracks the work of the Commission, illustrating the law both in action and in its broader political and historical context. It looks at its treatment of the judiciary and judicial conflicts, including the present crisis of the rule of law in Central Eastern Europe Member States of the European Union. Finally it suggests how all this can only be sensibly understood as a feature of the broader trend towards the internationalisation of constitutional law.
