When drafting the 1985 version of the Model Law, the UNCITRAL Working Group on International Contract Practices relied heavily on articles 9 and 10 of the 1976 version of the UNCITRAL Arbitration Rules, but introduced some significant modifications as well. The reason why the text of the Rules was modified is twofold: in some cases, the Commission decided to introduce some clarifications to avoid doubts that could have arisen if the text of the UNCITRAL Arbitration Rules were adopted without amendments. In other cases, instead, modifications were necessary because of the different nature of the Model Law, whose aim is to provide a transnational template for domestic arbitration statutes rather than to lay down rules to be adopted by private parties and incorporated in their agreement by reference.
