The Agreement aims to complete certain measures relating to the organisation of the arbitration, provided for in the European Convention on International Commercial Arbitration concluded in Geneva on 21 April 1961. The Agreement provides that the competent authority may decide, at the request of the party instituting proceedings, on any difficulties arising with regard to the constitution or functioning of the arbitral tribunal. This principle derogates from the provision of Article IV of the above-mentioned Convention on International Commercial Arbitration.
