The WTO and GATT settle disputes by the following
First Stage: up to 60 days
Before taking any action countries in dispute are allowed to resolve their differences themselves.
Second Stage: up to 45 days
If consultations fail, complaining country can ask for a panel to be appointed. The panel makes ruling and recommendations to help the Dispute Settlement Body.
