This publication contains the results of a research project carried out by the Swiss Arbitration Association (ASA) on a question that has received relatively little attention in legal commentary so far: performance as a remedy in international arbitration. Twelve contributions address, by reference to legal theory and to arbitration practice, the question of whether arbitrators can order a party to perform or abstain from performing certain acts (be it in the form of an interim order or in an award on the merits), in what circumstances, and how such orders are made and the issues of procedure and enforcement that they raise.
