Dispute resolution mechanisms are one of the key elements in commercial agreements and disputes. This was, specifically, one of the conflicting topics and which even left some bilateral agreements pending within negotiations of the United States-Mexico-Canada Agreement (USMCA), the agreement which will replace the North American Free Trade Agreement (NAFTA). The origin of the difficulties was the intentions of the US negotiators to maintain their protectionism and bring the proposals closer to their own commercial legislation. This article analyzes the different dispute resolution mechanisms in final documents and shows the complexity of the issue, as well as the alternatives specified in order to address the disputes. The central hypothesis is that the content of the text will involve an enormous effort due to the complexity of attention to the controversies as much from the varied mechanisms, as from the procedures and participants involved.
