(1B) If the application is for an all premises warrant, the justice of the peace must also be satisfied -

(a) that because of the particulars of the offence referred to in paragraph (a) of subsection (1) above, there are reasonable grounds for believing that it is necessary to search premises occupied or controlled by the person in question which are not specified in the application in order to find the material referred to in paragraph (b) of that subsection; and

(b) that it is not reasonably practicable to specify in the application all the premises which he occupies or controls and which might need to be searched.]
