Most police officers carry, or have access to, general search warrants issued by the Commissioner of Police which remain in force up to six months from the date of the warrant [see Summary Offences Act 1953 ss 67(1), 67(2), 67(3), and the Schedule for a copy of a general search warrant]. The police officer named in the warrant (along with his or her assistants) has the power to enter and search any premises where there is reasonable cause to suspect an offence has been or is about to be committed, the presence of stolen goods, evidence of an offence, or items intended to be used in an offence [see Summary Offences Act 1953 ss 67(4)(a)(i), 67(4)(a)(ii), 67(4)(a)(iii), 67(4)(a)(iv); and Reasonable Cause to Suspect (above)]. Whilst searching the premises, the police officer may break open and search cupboards, drawers, chests, trunks, boxes (and so forth) where there is reasonable cause to suspect the presence of stolen goods, evidence of an offence, or items intended to be used in an offence [see Summary Offences Act 1953 ss 67(4)(b)(i), 67(4)(b)(ii), 67(4)(b)(iii), 67(4)(b)(iv) and Reasonable Cause to Suspect (above)]. The police officer may seize items found as a result of the search [see Summary Offences Act 1953 s 67(4)(c)].
