Power of justice of the peace to authorise entry and search of premises
10.—(1) If on an application made by a constable a justice of the peace is satisfied that there are reasonable grounds for believing—
(a)that a serious arrestable offence has been committed; and
(b)that there is material on premises specified in the application which is likely to be of substantial value (whether by itself or together with other material) to the investigation of the offence; and
(c)that the material is likely to be relevant evidence; and
(d)that it does not consist of or include items subject to legal privilege, excluded material or special procedure material; and
(e)that any of the conditions specified in paragraph (3) applies,
he may issue a warrant authorising a constable to enter and search the premises.
(2) A constable may seize and retain anything for which a search has been authorised under paragraph (1).
(3) The conditions mentioned in paragraph (1)(e) are—
(a)that it is not practicable to communicate with any person entitled to grant entry to the premises;
(b)that it is practicable to communicate with a person entitled to grant entry to the premises but it is not practicable to communicate with any person entitled to grant access to the evidence;
(c)that entry to the premises will not be granted unless a warrant is produced;
(d)that the purpose of a search may be frustrated or seriously prejudiced unless a constable arriving at the premises can secure immediate entry to them.
(4) In this Order “relevant evidence”, in relation to an offence, means anything that would be admissible in evidence at a trial for the offence.
(5) The power to issue a warrant conferred by this Article is in addition to any such power otherwise conferred.
