The Amsterdam Centre for European Law and Governance (ACELG) was established as an Amsterdam Law School Centre of Excellence in 2009. Since then it has been nationally and internationally recognized as a research centre that makes high level contributions to the academic and policy debate on legal and governance processes in Europe. ACELG focusses on mapping, understanding and critically reflecting upon the constitutional (legal, political and economic) evolution that has taken place, and is taking place, in the European Union, including in the context of the proximate constitutional orders of the EU Member States as well as that of public international law.
