6
The Secretary of State shall not by regulations provide for any exceptions from the duties imposed by this section except so far as he considers it necessary to do so for the purpose of—
a
preventing the premature or inappropriate disclosure of information that is relevant to, or may be used in, any actual or prospective criminal proceedings;
b
preventing the disclosure of information in any circumstances in which it has been determined in accordance with the regulations that its non-disclosure—

is for the purposes of the prevention or detection of crime, or the apprehension or prosecution of offenders;
iii
is required on proportionality grounds; or
iv
is otherwise necessary in the public interest.
