Settling disputes is the responsibility of the Dispute Settlement Body (the General Council in another guise), which consists of all WTO members.
The Dispute Settlement Body has the sole authority to establish “panels” of experts to consider the case, and to accept or reject the panels’ findings or the results of an appeal. It monitors the implementation of the rulings and recommendations, and has the power to authorize retaliation when a country does not comply with a ruling.
First stage: consultation (up to 60 days). Before taking any other actions the countries in dispute have to talk to each other to see if they can settle their differences by themselves. If that fails, they can also ask the WTO director-general to mediate or try to help in any other way.
Second stage: the panel (up to 45 days for a panel to be appointed, plus 6 months for the panel to conclude). If consultations fail, the complaining country can ask for a panel to be appointed. The country “in the dock” can block the creation of a panel once, but when the Dispute Settlement Body meets for a second time, the appointment can no longer be blocked (unless there is a consensus against appointing the panel).
Officially, the panel is helping the Dispute Settlement Body make rulings or recommendations. But because the panel’s report can only be rejected by consensus in the Dispute Settlement Body, its conclusions are difficult to overturn. The panel’s findings have to be based on the agreements cited.
The panel’s final report should normally be given to the parties to the dispute within 6 months. In cases of urgency, including those concerning perishable goods, the deadline is shortened to three months. The agreement describes in some detail how the panels are to work.
