The Treaty of Lisbon is the revised version of the European Treaties that has endured the longest. These Treaties are still, and will likely remain for the foreseeable future, the fundamental texts of the European Union - beacons of democracy, human rights, rule of law, peace, social welfare and sustainable development.

The Treaty of Lisbon represented an extremely important achievement in European integration, and is a crucial instrument for the acknowledgement of the values, principles, institutions, policies and rules of the European Union. 

This article-by-article commentary on the European Treaties was first published in the Portuguese language, featuring detailed analyses from many eminent experts in European Union Law and policy, both from the public and private sectors, including academics, magistrates, lawyers, economists and members of the European institutions. 

The extraordinarily positive way in which the book was received encouraged the editors to launch an updated English digital edition, which considers the most recent legislation, case law, doctrine, economic and political developments, making it available to a global audience.
