Thurgood Marshall, United States Department of Justice v…
“ The control inquiry focuses on an agency's possession of the requested materials, not on its power to alter the content of the materials it receives. Agencies generally are not at liberty to alter the content of the materials that they receive from outside parties. An authorship-control requirement thus would sharply limit "agency records" essentially to documents generated by the agencies themselves. This result is incompatible with the FOIA's goal of giving the public access to all nonexempted information received by an agency as it carries out its mandate. ”
