United States district courts have jurisdiction to enjoin an agency from withholding agency records and to order production of any records improperly withheld. District courts also have jurisdiction to determine whether an agency has charged excessive fees for a FOIA request and whether the agency has improperly denied a fee waiver request. Courts may also have jurisdiction to review agency failure to publish information required by § 552(a )( 1) and refusal to make information available for inspection and copying under § 552(a)(2).
