(B) On complaint, the district court
of the United States in the district in which the complainant resides, or has
his principal place of business, or in which the agency records are situated,
or in the District of Columbia, has jurisdiction to enjoin the agency from
withholding agency records and to order the production of any agency records
improperly withheld from the complainant. In such a case the court shall
determine the matter de novo, and may examine the contents of such agency
records in camera to determine whether such records or any part thereof shall
be withheld under any of the exemptions set forth in subsection (b) of this
section, and the burden is on the agency to sustain its action. In addition to
any other matters to which a court accords substantial weight, a court shall
accord substantial weight to an affidavit of an agency concerning the agency's determination as to
technical feasibility under paragraph (2)(C) and subsection (b) and
reproducibility under paragraph (3)(B).
