The Willem C. Vis International Commercial Arbitration Moot is a competition for law students. Students from all countries are eligible. The Moot involves a dispute arising out of a contract of sale between two countries that are party to the United Nations Convention on Contracts for the International Sale of Goods. The contract provides that any dispute that might arise is to be settled by arbitration in Danubia, a country that has enacted the UNCITRAL Model Law on International Commercial Arbitration and is a party to the Convention on the Recognition and Enforcement of Foreign Arbitral Awards. The arbitral rules to be applied rotate yearly among the arbitration rules of co-sponsors of the Moot.
