Where any provision of Part II states that the duty to confirm or deny does not arise in relation to any information, the effect of the provision is that where either—
the provision confers absolute exemption, or
in all the circumstances of the case, the public interest in maintaining the exclusion of the duty to confirm or deny outweighs the public interest in disclosing whether the public authority holds the information,
section 1(1)(a) does not apply.
In respect of any information which is exempt information by virtue of any provision of Part II, section 1(1)(b) does not apply if or to the extent that—
the information is exempt information by virtue of a provision conferring absolute exemption, or
in all the circumstances of the case, the public interest in maintaining the exemption outweighs the public interest in disclosing the information.
