SIGNIFICANCE OF NON-COMPLIANCE WITH SECTION 3H(1)
25 As mentioned above, the Commissioner ultimately conceded on appeal that the document made available to Mr Oke in purported compliance with s 3H(1) of the Crimes Act was not a copy of the warrant. It is thus unnecessary for this Court to give consideration to the extent to which a document may fail accurately to reproduce every aspect of a warrant before it loses the character of a copy of that warrant within the meaning of s 3H(1). We doubt, however, that s 3H(1) calls for a facsimile of the warrant to be made available to the occupier of the premises. Whether a document is a copy of a warrant within the meaning of s 3H(1) is a question of fact to be determined in the light of the purpose of the Act following a comparison of the two documents and an assessment of the significance of any unauthorised differences between them.
26 The consequence of the above concession made by the Commissioner is that he is to be taken to accept that the obligation imposed upon those executing the warrant by s 3H(1) was not complied with. Nothing in the Crimes Act suggests that a copy of a warrant can be made available to an occupier wholly or partly orally. As a warrant is a document a copy of a warrant must also be a document.
27 It is therefore necessary to determine whether the execution of the warrant was rendered unlawful because of the non-compliance with s 3H(1).
28 In Project Blue Sky Inc v Australian Broadcasting Authority (1998) 194 CLR 355 the High Court gave consideration to whether a program standard determined by the Australian Broadcasting Authority under the Broadcasting Services Act 1992 (Cth) was invalid because the Authority failed to comply with the requirement of s 160(d) of that Act. Section 160(d) required the Authority to perform its functions in a manner consistent with any agreement between Australia and a foreign country. It was common ground between the parties that the program standard in question was in conflict with articles in the Protocol on Trade in Services to the Australian New Zealand Closer Economic Relations Trade Agreement.
29 In the majority judgment of the High Court, McHugh, Gummow, Kirby and Hayne JJ at [91] stated:
'An act done in breach of a condition regulating the exercise of a statutory power is not necessarily invalid and of no effect. Whether it is depends upon whether there can be discerned a legislative purpose to invalidate any act that fails to comply with the condition. The existence of the purpose is ascertained by reference to the language of the statute, its subject matter and objects, and the consequences for the parties of holding void every act done in breach of the condition. Unfortunately, a finding of purpose or no purpose in this context often reflects a contestable judgment. The cases show various factors that have proved decisive in various contexts, but they do no more than provide guidance in analogous circumstances. There is no decisive rule that can be applied; there is not even a ranking of relevant factors or categories to give guidance on the issue.' (footnote omitted)
30 The majority judgment at [93] described the distinction between directory and mandatory requirements, and the division of directory acts into those which have substantially complied with statutory command and those which have not, as classifications that are no longer useful because they deflect attention from the real issue which is whether an act done in breach of a legislative provision is invalid.
31 The approach adopted by the majority of the High Court in Project Blue Sky 194 CLR 355 is applicable in this appeal. It is thus appropriate to turn first to the Crimes Act, and particularly s 3H(1), to see whether the language of the Act, the subject matter and objects of its relevant provisions, and the consequences of holding void every execution of a warrant undertaken in breach of s 3H(1) indicate a legislative purpose to render unlawful an execution conducted in breach of s 3H(1).
32 Weight, although not compelling weight, is to be given to the use of the word 'must' in s 3H(1). It is plain that those executing the warrant were under a legal obligation to make available to Mr Oke a copy of the warrant. To the extent that the Commissioner may have argued to the contrary, the argument should be rejected.
33 Additionally, weight, but again not compelling weight, is to be given to the fact that there are other sections of the Crimes Act which provide expressly that a failure to comply with the section does not affect the validity of what is done under the section. For example, s 15N(1) provides that a certificate authorising a controlled operation 'must' be in writing and signed by the authorising officer. Section 15N(2) provides that the certificate 'must' state various things and give a brief description of the operation that includes nominated details. Yet s 15N(5) provides:
'A failure to comply with this section does not affect the validity of a certificate authorising a controlled operation.'
Section 15Q which requires that the Chief Executive Officer of Customs be notified of certain certificates authorising a controlled operation is similarly drafted. Some significance may be attached to the absence in s 3H of a subsection providing that failure to comply with the section, or with subsection (1), does not affect the lawfulness of the execution of the warrant.
34 Other relevant considerations are that the obligation imposed by s 3H(1) is relatively easily complied with and that it serves an important purpose. Unless the occupier of the premises has available to him or her a copy of the warrant it will be extremely difficult for the occupier to monitor the conduct of those executing the warrant for the purpose of ensuring that nothing is seized in purported compliance with the warrant that is not authorised to be so seized. This point may be illustrated by reference to the terms of the warrant in this case. The warrant authorised the seizure only of evidentiary material that satisfied all of three conditions. The first of the conditions required that the evidentiary material be originals or copies of one or more of 26 different categories of things. It is fanciful to think that an occupier who was only shown the warrant, or only had the warrant read to him or her, could memorise the conditions and categories for the purpose of challenging any particular seizure.
35 Moreover, a finding that a warrant was executed unlawfully does not foreclose the issue, and lawful execution, of another warrant with respect to the same premises or another place to which evidentiary material therefrom may have been moved.
36 Additionally, as the Full Court observed in Hart v Commissioner of Australian Federal Police (2002) 124 FCR 384 at [66], a strict approach to the construction of, and compliance with, statutory provisions authorising the issue and execution of search warrants has repeatedly been enjoined by the courts. The Full Court at [66] quoted the following passage from the judgment of the High Court in George v Rockett (1990) 170 CLR 104 at 110-111:
'… in construing and applying such statutes, it needs to be kept in mind that they authorize the invasion of interests which the common law has always valued highly and which, through the writ of trespass, it went to great lengths to protect. Against that background, the enactment of conditions which must be fulfilled before a search warrant can be lawfully issued and executed is to be seen as a reflection of the legislature's concern to give a measure of protection to these interests. To insist on strict compliance with the statutory conditions governing the issue of search warrants is simply to give effect to the purpose of the legislation.'
37 The conclusion in Hart at [68] that there is no requirement to approach the task of construing statutes authorising the issue of warrants 'armed with a prima facie hostility to the invasion of privacy that is necessarily involved in the exercise of investigative powers' was not intended, in our view, to undermine the significance of the considerations identified in the above passage from George v Rockett.
38 The Commissioner contended that a factor which suggested that failure to comply with s 3H(1) was not intended to render unlawful the execution of the warrant was the continuing operation of the common law obligation to show the original warrant to the occupier of the premises. This is not an appropriate case, in our view, for a determination to be made as to whether that common law obligation survived the enactment of Part IAA of the Crimes Act, which relates to search warrants and powers of arrest. We note, however, the following passage in the relevant Explanatory Memorandum:
'The Bill replaces the existing provisions of the Crimes Act dealing with the issue of search warrants and powers of arrest and spells out details of the manner in which these powers may be exercised. Much of this detail is currently dealt with under common law, State and Territory law or in police instructions, general orders and practice and hence generally unavailable to the public. The Bill is designed to make public the powers of police and the rights of individuals in the important areas of police investigation with which it deals. The unavailability of the details is incompatible with modern concepts of open administration and access to justice.' (Crimes (Search Warrants and Powers of Arrest) Amendment Bill 1994 (Cth) Explanatory Memorandum)
39 As the majority judgment in Project Blue Sky (see [29] above) recognises, a finding that a statute does or does not disclose a purpose that an act done in breach of one of its requirements should be invalid or unlawful will often reflect a contestable judgment. It is necessary to make such a judgment in this case. Having regard to the matters outlined above, and accepting (but without deciding) that the common law obligations to show the original warrant to the occupier may have survived the enactment of Part IAA, our judgment is that the Crimes Act discloses an intention that non-compliance with s 3H(1) renders unlawful the execution of the warrant.
40 We note that while the requirement of s 15(3) of the Search Warrants Act 1985 (NSW) is not in the same terms as s 3H(1) of the Crimes Act, its requirement that the 'occupier's notice' for which s 15 provides be served on the occupier has been treated as being of such a kind that non-compliance with it has rendered execution of a search warrant unlawful, even though s 15 does not expressly provide for that consequence: see Black v Breen [2000] NSWSC 987 at [36]; Ballis v Randall [2007] NSWSC 422 at [111] -[127]. Because of the different legislative régimes, the two cases cited are not on all fours with the present case, but the approach taken to the requirement of service of an occupier's notice conforms to that which we take to the requirement that a copy of the warrant be made available to the occupier.
