Other proposals would give the country winning a GATT dispute an automatic right to withdraw concessions if, after a specified time, the defending party has neither complied with a panel's recommendations nor agreed to an acceptable timetable for compliance. GATT rules and procedures currently contain no time limits for implementation f panel reports, and implementation may be delayed indefinitely.
