Despite the evolution and the experience in the field of ODR, it appears that some aspects remain to be clarified in order to attempt to determine which type of procedure would be best adapted to consumer disputes. What does online arbitration mean and is this ODR? What is the profile of the users making use of ODR? What mechanisms are adapted to business disputes and to consumer disputes? Are procedural issues for disputes resolved through mediation similar to those resolved through arbitration? The article discusses about indispensable clarifications which may have an impact on the choice of procedure: mediation or arbitration. It then raises issues related to the UNCITRAL ODR WG discussions on a redress system for cross-border consumer disputes and questions whether types of disputes and potential mechanisms are not confused. Finally, the European Union which adopted a Regulation on ODR for consumer disputes may have found a solution.
