4 (1) In relation to premises other than premises occupied as a private dwelling, a lay magistrate may exercise the power in sub-paragraph (3) if the magistrate is satisfied by complaint on oath—N.I.
(a)that for the purpose of the proper exercise of the functions of a district council under this Act there are reasonable grounds for entering into any premises; and
(b)of either or both of the matters mentioned in sub-paragraph (2).
(2) The matters are—
(a)that admission to the premises has been, or is likely to be, refused, and that notice of intention to apply for a warrant under this Schedule has been given to the occupier or a person who reasonably appears to the district council to be concerned in the management of the premises;
(b)that an application for admission, or the giving of such notice, would defeat the object of the entry, or that the premises are unoccupied, or that the occupier is temporarily absent and it might defeat the object of the entry to await the occupier's return.
(3) A lay magistrate may issue a warrant authorising the authorised officer to enter the premises, if need be by force.
