The final version of the panel's report is distributed first to the parties; two weeks later it is circulated to all the members of the WTO. In sharp contrast with other systems, the report is required to be adopted at a meeting of the DSB within 60 days of its circulation, unless the DSB by consensus decides not to adopt the report or a party to the dispute gives notice of its intention to appeal. A party may appeal a panel report to the standing Appellate Body, but only on issues of law and legal interpretations developed by the panel. Each appeal is heard by three members of the permanent seven-member Appellate Body set up by the Dispute Settlement Body and broadly representing the range of WTO membership. Members of the Appellate Body have four-year terms. They must be individuals with recognized standing in the field of law and international trade, not affiliated with any government. The Appellate Body may uphold, modify or reverse the panel's legal findings and conclusions. Normally appeals should not last more than 60 days, with an absolute maximum of 90 days. The possibility for appeal makes the WTO dispute resolution system unique among the judicial processes of dispute settlement in general public international law.
