6.—(1) Notwithstanding any limitation on the powers of a council which grants an indemnity, the council may provide an indemnity to the extent that the member or officer in question–
(a)believed that the action, or failure to act, in question was within the powers of the council; or
(b)where that action or failure comprises the issuing or authorisation of any document containing any statement as to the powers of the council, or any statement that certain steps have been taken or requirements fulfilled, believed that the contents of that statement were true,
and it was reasonable for that member or officer to hold that belief at the time when the member or officer acted or failed to act.
(2) An indemnity may be provided in relation to an act or omission which is subsequently found to be beyond the powers of the member or officer in question but only to the extent that the member or officer reasonably believed that the act or omission in question was within the powers of the member or officer at the time at which the member or officer acted.
