On June 2, 2008, a World Trade Organization (WTO) Appellate Body (AB) publicly released its final report upholding a December 2007 compliance panel ruling that the United States has not fully complied with a March 2005 WTO ruling against certain U.S. cotton support programs. This AB ruling was part of a prolonged dispute settlement case (DS267) originated by Brazil against certain aspects of the U.S. cotton program in September 2002. This report provides a brief overview of Brazil's case against the U.S. cotton program, the evolution and current status of the case, and the potential role for Congress.
