Upon a receipt of a request, a public body must respond in accordance with the established provisions and timeframes in subsection B of § 2.2-3704. If part of the requested records are being withheld from release, a public body shall identify with reasonable particularity the subject matter of withheld portions, and cite, as to each category of withheld records, the specific Code section that authorizes the withholding of the records. Considering the policy of FOIA and the legal duties it imposes, there is a presumption of good faith that a custodian of records will obey the law in carrying out their duties by searching for and providing all records as requested unless the records are exempt or prohibited from release. FOIA is intended to be a non-adversarial process for obtaining information.
