For more than a decade, an environmental law group has pressed the government for access to documents that were created during trade talks among dozens of nations in the Western Hemisphere.
Now, a one-page position paper is all that remains contested in the long-running case in Washington's federal trial court.
The U.S. Justice Department says the document is classified and that releasing it will hurt foreign relations--jeopardizing the trust other countries have in the United States to keep certain information confidential.
A federal trial judge in Washington didn't buy the argument. Earlier this year, in a rare move, U.S. District Judge Richard Roberts ordered the government to disclose the document to the Center for International Environmental Law. The ruling didn't end the tiff.
DOJ is now fighting in the U.S. Court of Appeals for the D.C. Circuit to protect the secrecy of the single page of information that's called "Document 1" in court papers.
