Members may express their views on the report of the Appellate Body, but they cannot derail it. The DSU states unequivocally that an Appellate Body report shall be adopted by the DSB and unconditionally accepted by the parties, unless the DSB decides by consensus within thirty days of its circulation not to adopt the report. Unless otherwise agreed by the parties to the dispute, the period from establishment of the panel to consideration of the report by the DSB shall as a general rule not exceed nine months if there is no appeal, and twelve months if there is an appeal.
