Most of the activities of the Energy Task Force have not been disclosed to the public, even though Freedom of Information Act (FOIA) requests (since 19 April 2001) have sought to gain access to its materials. The organisations Judicial Watch and Sierra Club launched a law suit (U.S. District Court for the District of Columbia: Judicial Watch Inc. v. Department of Energy, et al., Civil Action No. 01-0981) under the FOIA to gain access to the task force's materials. After several years of legal wrangling, in May, 2005 an appeals court permitted the Energy Task Force's records to remain secret.
