Local Government Act 1993

A meeting is not to remain closed during the discussion of anything referred to in section 10A(2)—

except for so much of the discussion as is necessary to preserve the relevant confidentiality, privilege or security, and

if the matter concerned is a matter other than a personnel matter concerning particular individuals, the personal hardship of a resident or ratepayer or a trade secret—unless the council or committee concerned is satisfied that discussion of the matter in an open meeting would, on balance, be contrary to the public interest.

A meeting is not to be closed during the receipt and consideration of information or advice referred to in section 10A(2)(g) unless the advice concerns legal matters that—

are substantial issues relating to a matter in which the council or committee is involved, and

are clearly identified in the advice, and

are fully discussed in that advice.

If a meeting is closed during the discussion of a motion to close another part of the meeting to the public (as referred to in section 10A(3)), the consideration of the motion must not include any consideration of the matter or information to be discussed in that other part of the meeting (other than consideration of whether the matter concerned is a matter referred to in section 10A(2)).

For the purpose of determining whether the discussion of a matter in an open meeting would be contrary to the public interest, it is irrelevant that—

a person may misinterpret or misunderstand the discussion, or

the discussion of the matter may—

cause embarrassment to the council or committee concerned, or to councillors or to employees of the council, or

cause a loss of confidence in the council or committee.

In deciding whether part of a meeting is to be closed to the public, the council or committee concerned must have regard to any relevant guidelines issued by the Departmental Chief Executive.
