(2) A request for information under the Official Information Act 1982 or under the Local Government Official Information and Meetings Act 1987 (other than one made by a constable for the purpose of investigating an offence) may be refused, as contrary to this Act, if it might identify a person who has made a protected disclosure.

(b) otherwise provide advice and assistance to organisations and other persons in relation to the duty specified in subsection (1).
