ONLINE DISPUTE RESOLUTION
The European Commission has created the ODR platform for the alternative resolution of disputes between consumers and traders concerning online sales or service contracts. "Online sales or service contract": a sales or service contract where the trader, or his intermediary, offers goods or services on a website or through other electronic means, which the consumer orders on that website or through other electronic means (Regulation (EU) No 524/2013 of the European Parliament and of the Council of 21 May 2013).
