30. (1) An authorisation under section 27 or 28 shall expire on the expiry date specified therein.

(2) Subject to subsection (3), where an authorisation expires in accordance with subsection (1)—

(a) the person to whom the authorisation was given shall, as soon as may be, terminate, or cause the termination of, the operation of the CCTV to which the expired authorisation relates, and

(b) where further installation, operation or both, of the CCTV concerned is required, it shall be necessary for him or her to apply for a new authorisation under section 27 or 28, as the case may be, in relation to such installation, operation or both.

(3) Where an application for a new authorisation to which subsection (2)(b) refers has been made and the existing authorisation concerned would, but for this subsection, expire before the Commissioner of the Garda Síochána has decided whether to give a new authorisation referred to in that subsection, the existing authorisation shall be deemed not to expire until that decision has been made.
