Regulation 17 Opted in authority ceasing to qualify: duty to notify
An opted in authority which becomes a full audit authority must give notice to the relevant specified person that it is a full audit authority as soon as practicable after it becomes a full audit authority.
An opted in authority which ceases to be a smaller authority must, as soon as practicable after the day on which it ceases to be such an authority, give notice of that fact to the relevant specified person.
An opted in authority which ceases to fall within the class of authority for which the specified person was the relevant specified person, must give notice to the relevant specified person as soon as practicable after it should reasonably have been aware that it no longer fell within the class.
Paragraph (5) applies where an authority fails to give notice to the relevant specified person as required by paragraph (1), (2) or (3).
The relevant specified person may recover any reasonable costs incurred in relation to that authority by—
the specified person, or
a local auditor appointed to the authority by the specified person,
until the date when the authority in fact gives notice to the specified person.
