On Thursday, 25 January 2018, the BIICL Investment Treaty Forum and Wilmer Cutler Pickering Hale and Dorr LLP are hosting a seminar on the subject of "The ne ultra petita principle and international investment treaty arbitration".

Professor Attila Tanzi, Chair of International Law at the University of Bologna, will address the ne ultra petita principle within the framework of an emerging common law of international adjudication and arbitration. In particular, he will consider it in relation to the counter-balancing principle of iura novit curia.

The principle's application in investor-State dispute settlement (ISDS) will be analysed with a special focus on ICSID arbitration, having special regard to its relevance for the purposes of annulment proceedings under Article 52 of the Washington Convention.


Professor Maxi Scherer, Wilmer Cutler Pickering Hale and Dorr LLP and Queen Mary, University of London.


  • Sir Frank Berman KCMG QC, Essex Court Chambers
  • Maurice Mendelson QC, Blackstone Chambers

This event is convened by Prof Yarik Kryvoi, Senior Research Fellow in International Economic Law and Director of the Investment Treaty Forum.
