Section 42 of the Freedom of Information Act provides that:
Information in respect of which a claim to legal professional privilege
or, in Scotland, to confidentiality of communications could be maintained
in legal proceedings is exempt information.
The duty to confirm or deny does not arise if, or to the extent
that, compliance with section 1(1)(a) would involve the disclosure
of any information (whether or not already recorded) in respect of
which such a claim could be maintained in legal proceedings.
