Case law considering "reasonably necessary for the protection of … lawful interests"
11 Numerous cases have considered the phrase "reasonably necessary for the protection of the lawful interests of" the principal party to a conversation who has consented to it being recorded in the Surveillance Devices Act, and a similar phrase in the predecessor Listening Devices Act 1984 (NSW). In Violi v Berrivale Orchards Ltd [2000] FCA 797; 99 FCR 580, Branson J considered the meaning of the phrase "lawful interests" as it appeared in s 5(3)(b)(i) of the Listening Devices Act, being a relevantly identical exclusion to a relevantly identical prohibition to the present provision. There are, however, two notable differences between the two statutes:
(1) the recording offence now expressly references mens rea with the requirement that the person must "knowingly install, use or cause to be used or maintain a listening device" (emphasis added); and
(2) s 13 of the prior Listening Devices Act contained an express and absolute prohibition on admitting evidence of such a conversation obtained as a direct consequence of a contravention unless innocently obtained, to be contrasted with the balancing exercise required by s 138 of the Evidence Act (noting that in this Court, s 13 was not picked up as surrogate federal law because it conflicted with s 138).
12 In Violi, Branson J, in agreeing with prior authority, held (at [23]) that to fall within the analogous exception under consideration, the recording of the conversation needed to be, "as a matter of objective judgment, necessary for the protection of an actual lawful interest, existing as at the time of the conversation, of that principal party". Her Honour then stated:
[28] Unassisted by authority, it seems to me that "lawful interests" are to be distinguished from "legal interests". I do not consider that s 5(3)(b)(i) calls for a legal interest in the sense of a legal right, title, duty or liability. Rather I consider that "lawful interests" within the meaning of the paragraph are interests which are not unlawful. The expressions "legitimate interests" or "interests conforming to law", in my view, convey similar meanings to the intended meaning of "lawful interests" in the paragraph.
…
[32] It is not necessary for me to attempt to determine exhaustively the types of circumstance in which the recording of a conversation by a principal party to the conversation "is reasonably necessary for the protection of the lawful interests of that principal party" within the meaning of s 5(3)(b)(i) of the Listening Devices Act. I am inclined, however, to think that the recording of a conversation intended by the parties involved to result in an oral contract in terms outlined during the conversation would be such a circumstance. I interpolate that that is, of course, not this case as the alleged contract is pleaded to have been made before the date of the two conversations. Similarly, I am inclined to think that the recording by one party of a threatening telephone conversation or of a conversation forming part of a blackmail attempt would fall within the paragraph. However, such circumstances are far from the circumstances of this case.
13 In R v Le [2004] NSWCCA 82; 60 NSWLR 108, the appellant had been charged with two offences under s 5(1)(b) of the Listening Devices Act, the equivalent of s 7(1)(b) of the Surveillance Devices Act, and convicted in the Local Court. Ms Le had sought to record an admission as to the murder of a member of parliament. She was a close associate of another man who had been convicted of that murder. On an appeal to the District Court, a case was stated for the consideration of three questions by the Court of Criminal Appeal. The third question concerned the defence in s 5(3)(b)(i) and whether it had been correctly applied. That involved the question of whether it was reasonably necessary to record the conversation in order to protect Ms Le's lawful interests.
14 In his dissenting judgment in Le, Giles JA considered the lawful interests which Ms Le relied upon to enliven the defence, being that she recorded the conversation to protect her credibility generally, to support her credibility if she had to give evidence in Court, and, to protect herself against exposure to being charged with making serious false allegations. His Honour held that it was open to the District Court judge hearing the appeal from the Local Court (which is ordinarily an appeal by way of rehearing on the papers) to find that the recording was not reasonably necessary based on any of these interests. His Honour noted that the concern about having a supporting record before making allegations was more significant than the other two interests relied upon, but that it was ultimately open to be found to be insufficient.
15 Conversely, Hulme J agreed with Adams J in Le that the defence had been made out in the particular circumstances of that case, but expressed grave doubts that, as a general proposition, recording a conversation to ensure there was an irrefutable record of it could be regarded as protected. Adams J went further in finding that as there was a moral duty and possibly a legal duty to report an admission of the commission of a serious offence, which was the intended content of the conversation. His Honour concluded that, while recording the conversation was not absolutely necessary, it was reasonably necessary. Thus the case really turned on a factual assessment.
16 In Sepulveda v R [2006] NSWCCA 379; 167 A Crim R 108, an adult complainant in relation to sexual assault allegations recorded the appellant's admissions of sexual activity with him when he was a child. The defence under the Listening Devices Act was not upheld, and the recording therefore rendered inadmissible, because the complainant could have gone to the police with his complaints rather than approach the appellant himself to record the conversation. Johnson J (with whom McClellan CJ at CL and Hislop J agreed) concluded:
(1) as to "reasonably necessary" at [117]-[118], "it is sufficient that the recording of a conversation is reasonably appropriate (rather than essential) for the protection of the lawful interests of the principal party", being an objective test based on the grounds that existed at the time of the recording, citing several cases including Violi at [17]-[18], [23];
(2) as to "protection" at [120]:
According to the Macquarie Dictionary, the meaning of the noun "protection" includes "preservation from injury or harm". The Oxford English Dictionary definition includes "shelter, defence, or preservation from harm, danger, or evil". In Udini v Aldo t/a Fine Line Joinery Pty Ltd (1998) 16 NSWCCR 418, her Honour Judge Truss accepted this meaning of the word "protection" in the section in concluding (at [19]) that "the applicant's lawful interests were in need of 'defence from harm, danger and evil' at the time when the recording was made and that the use of the device was reasonably necessary for the protection of his lawful interests". This meaning seems apt given the statutory context in which the word appears.
(3) as to "lawful interests" at [125], the relevant cases revealed that findings were made where the defence was both enlivened and where it was not, and that these findings depended on the circumstances of a particular case; and at [126], that it was possible that Branson J's construction in Violi was too wide, but that this did not need to be determined.
17 Thomas v Nash [2010] SASC 153; 107 SASR 309 was a succession case about a similar provision in South Australia containing an exception to the prohibition on the use of a covert recording by a participant if it is "reasonably required for the protection of the person's lawful interests". In the context of discussing prior cases including Violi, Le and Sepulveda, Doyle CJ observed:
[47] In none of those decisions is there an attempt to identify comprehensively the scope of the expression "lawful interests". That is not surprising. It is an expression which is best left to be applied case-by-case, subject to some general guidelines.
[48] Each decision is an application of the expression to its particular facts. In most of those decisions it was accepted that a mere desire to have a reliable record of a conversation is not enough. I agree. Most of the decisions proceed on the basis that a desire to gain an advantage in civil proceedings would not ordinarily amount to a relevant lawful interest, although of course each case has to be considered on its facts. Several of the cases proceed on the basis that where the conversation relates to a serious crime, or an allegation of a serious crime, or to resisting such an allegation, a court is more likely to find that the recording of a conversation relating to the crime can be made in the protection of the person's "lawful interests".
18 DW v The Queen [2014] NSWCCA 28; 239 A Crim R 192 was an appeal which included a challenge to the decision of a trial judge to admit into evidence a covert recording of a conversation the appellant father had with his complainant adolescent daughter, during which he solicited further sexual conduct with her. The recorded conversation took place after he had engaged in conduct constituting numerous sexual offences for which he was later convicted. The trial judge found that the exclusion in s 7(3)(b)(i) of the Surveillance Devices Act applied, because the recording was reasonably necessary for the protection of the lawful interests of the complainant, being "to protect herself from being the victim of the alleged criminal offences perpetrated by the [appellant]", and even if that had not been so, would have admitted the recording under s 138 of the Evidence Act.
19 In upholding that ruling in DW v The Queen, Ward JA (with whom Harrison and RA Hulme JJ agreed) surveyed a range of authority, including those referred to above. At [42] and following, her Honour apparently endorsed the view expressed by Johnson J in Sepulveda summarised above, that to meet the test of "reasonably necessary" it is sufficient that the recording of a conversation is reasonably appropriate, rather than essential, for the protection of the lawful interests of the participant who consents to that recording. Her Honour adopted this view while setting out the clear distinction between the factual circumstances of the two cases, seemingly embracing the factual nuance in such matters also addressed by Johnson J in Sepulveda at [125]. Additionally, at [34], her Honour did not express any concern at the conclusion reached by Brereton J (as his Honour then was) in Chao v Chao [2008] NSWSC 584 at [8] that a lawful interest might arise in relation to a recording made where a serious dispute had erupted and it was anticipated there would be a dispute as to different versions of an arrangement. However, that falls short of being a clear endorsement of that expansive view.
20 The conclusion I reach is that all of the above authority provides some assistance and marks out some useful barriers, but the ultimate determination is highly fact-specific and cannot simply be reached through comparison against some exhaustive checklist of factors. All the same, some useful guidance is to be found in the recent succession case of Rathswohl v Court [2020] NSWSC 1490, in which Rees J observed at [35]:
The following considerations may indicate whether recording a private conversation without consent may be "reasonably necessary for the protection of the lawful interests" of the person making the recording.
(a) Whether the purpose of the conversation was to obtain admissions in support of a legitimate purpose. The contentious subject matter of the conversation, or the characteristics of the person being recorded, may indicate that it was necessary to make the recording in order to secure the admission. Recording a conversation for the purpose of extracting money, inducing further improper conduct or to blackmail the recorded party will indicate to the contrary.
(b) Whether it was important to protect oneself from being accused of fabricating a conversation and recording the conversation was the only practical means of refuting such an allegation. This is more likely to be the case where the conversation concerns a serious criminal matter or the principal party has a genuine concern for their safety or that of their children.
(c) Whether there were other practical means of recording the conversation, for example, reporting the matter to police or making a contemporaneous file note.
(d) Whether there was a serious dispute on foot between the parties, including where determination of the dispute would vitally depend upon oral evidence and thus, one person's word against another. Recordings of conversations 'just in case' there is a dispute, or for the sake of making an accurate record of what was said, is not enough.
