Subject to subsection (2), a disclosure of any information, document, equipment or other item which is required or authorised by or under section 119 or 120 or Schedule 14 does not breach—
any obligation of confidence owed by the person making the disclosure, or
any other restriction on disclosure.
Nothing in this Part operates to require or authorise a disclosure of information which would contravene the data protection legislation (but, for the purposes of this subsection, in determining whether a disclosure required or authorised by or under this Part would do so, take the requirement or authorisation into account).
