From Council on Foreign Relations :
Letter to President Trump signed by 26 business and agriculture:
“We urge your administration to embrace the plan to renovate the WTO appeals process outlined below. The proposal seeks to reform the Appellate Body in a manner consistent with concerns raised by USTR. . . .
“USTR has resisted negotiating reforms to the WTO appeals process until other countries acknowledge that the Appellate Body has strayed beyond its mandate. The Walker Principles were developed with the purpose of restoring proper functioning to the Appellate Body. By adopting them along with the related enforcement measures and term limits for the secretariat, WTO members would be agreeing with the United States that the Appellate Body has overreached.”
“We urge your administration to strike while the iron is hot by stating prior to December 10 that the goal of the United States is not to kill the Appellate Body, but rather to reform it. The statement should clarify that adoption of the reform plan would end U.S. opposition to the appointment of new Appellate Body members.”

Letter to President Donald J. Trump signed by 10 business and trade association groups:
“We strongly urge you to state publicly that the goal of the United States is not to kill the Appellate Body, but rather to reform it. We further urge you to develop a reform proposal as quickly as possible and present it to WTO members, while indicating that adoption of such measures would lead to restarting the Appellate Body appointment process. This approach would maximize leverage for reform. That leverage is likely to decrease significantly if the Appellate Body stops functioning; some countries already have agreed to use arbitration procedures in lieu of formal appeals. The Appellate Body will go dormant in December unless new members are approved promptly. By acting expeditiously, the United States could lead a process of constructive change. Doing so would help to strengthen worldwide business confidence. This would serve the best interests of the many American companies and workers that earn all or part of their livelihoods from international trade.
