WASHINGTON, D.C. - The District of Columbia Circuit U.S. Court of Appeals on June 7 reversed a district court's ruling that the U.S. Trade Representative must release a document that was introduced during negotiations of a free-trade agreement with foreign nations, finding that the trade representative properly withheld the document as confidential (Center for International Environmental Law v. Office of the United States Trade Representative, et al., No. 12-5136, D.C. Cir.; 2013 U.S. Dist. App. LEXIS 11477).
