On September 27, 2019, the Institute for Energy and Regulatory Law Berlin and the Hellenic Energy Regulation Institute hosted in Athens an international congress on Energy Arbitration and Judicial Dispute Settlement. The contributions in this book reflect the wide range of current subjects dealt with, spanning from the representative actions in the energy sector over the landmark Achmea judgment of the European Court of Justice to the dynamic relationship between the principle of autonomy of EU Law and investment arbitration.
