What is a request for consultations?
The request for consultations formally initiates a dispute in the WTO. Consultations give the parties an opportunity to discuss the matter and to find a satisfactory solution without proceeding further with litigation. After 60 days, if consultations have failed to resolve the dispute, the complainant may request adjudication by a panel.
