Over the last few years, the United States has been pressuring the World Trade Organization (WTO) to reform the Appellate Body by refusing proposals to fill vacancies. On December 10, 2019, the terms of two Appellate Body members expired, leaving one member left for the seven-member body. This has brought new appeals to a standstill, as an appeal from a panel established by the Dispute Settlement Body must be heard by three Appellate Body members. In February of 2020, the United States elaborated on its complaints about the Appellate Body in a report published by the Office of the United States Trade Representative. In the spring of 2020, in response to the continued U.S. resistance to filling vacancies on the Appellate Body, a group of WTO members established an interim arrangement to handle appeals through arbitration. Also in the spring of 2020, the United States described as invalid a recent Appellate Body report regarding a dispute between Canada and the United States, asserting that none of the three persons who issued the report were in fact bona fide Appellate Body members.
