(2) If a court is satisfied that -

(a) it is necessary to enter any specified premises, vessel, aircraft or vehicle, for the purpose of obtaining such information which will enable the Commission to gather necessary evidence in accordance with the provision of subsection (1);

(b) access to such premises, vessel, aircraft or vehicle for the purpose of obtaining such evidence as aforesaid has, within seven days before the date of the application to the court, been sought by a person duly authorised in that behalf by the Commission and has been denied,

Provided that an authorisation shall not be issued under this subsection unless either -

(i) it is shown to the court that the Commission is satisfied that there are
reasonable grounds for believing that the use of the station or apparatus in question is likely to cause undue interference with any radio-communication used for the purposes of any safety-of life-service or any purpose on which the safety of any person or of any vessel, aircraft or vehicle may depend; or

(ii) it is shown to the court that not less that seven days' notice of the demand for access was served on the owner or occupier of the premises, or, the person in possession or in charge of the vessel, aircraft or vehicle, and that the demand was made at a reasonable hour and was unreasonably denied.

(3) Where under this section a person is authorised to examine and test any telecommunication system or telecommunication apparatus or radio-communication apparatus on any premises or in any vessel, aircraft or vehicle, it shall be the duty of any person who is on the premises, or is in charge of, or in attendance on, the vessel, aircraft or vehicle, to give such authorised person such assistance as he may reasonably require in the examination or testing of such station or such apparatus.
