97 The parties each relied upon a judgment given by Peterson J in Scanruby Pty Ltd v Caltex Petroleum Pty Ltd and Anor [2000] NSWIRComm 89. There his Honour considered the proper construction of various provisions of the Listening Devices Act, which also here arose for consideration. The question being whether the tape-recording offended the provisions of s5(1) of that Act, or rather fell within the provisions of s5(3). Section 5 provides:
5 Prohibition on use of listening devices
(1) A person shall not use, or cause to be used, a listening device:
(a) to record or listen to a private conversation to which the person is not a party, or
(b) to record a private conversation to which the person is a party.
(2) Subsection (1) does not apply to:
(a) the use of a listening device pursuant to a warrant granted under Part 4,
(b) the use of a listening device pursuant to an authority granted by or under the Telecommunications (Interception) Act 1979 of the Commonwealth or any other law of the Commonwealth,
(c) the use of a listening device to obtain evidence or information in connection with:
(i) an imminent threat of serious violence to persons or of substantial damage to property, or
(ii) a serious narcotics offence,
if it is necessary to use the device immediately to obtain that evidence or information,
(d) the unintentional hearing of a private conversation by means of a listening device, or
(e) the use of a listening device to record a refusal to consent to the recording of an interview by a member of the police force in connection with the commission of an offence by a person suspected of having committed the offence.
(3) Subsection (1) (b) does not apply to the use of a listening device by a party to a private conversation if:
(a) all of the principal parties to the conversation consent, expressly or impliedly, to the listening device being so used, or
(b) a principal party to the conversation consents to the listening device being so used and:
(i) the recording of the conversation is reasonably necessary for the protection of the lawful interests of that principal party, or
(ii) the recording of the conversation is not made for the purpose of communicating or publishing the conversation, or a report of the conversation, to persons who are not parties to the conversation.
(4) Where a listening device is used in the circumstances referred to in subsection (2) (c) and its use would, but for subsection (2) (c), be contrary to this section, the person who used the device shall:
(a) forthwith cause to be served on the Attorney General or a prescribed officer notice of that fact, and
(b) within 7 days after its use, furnish a report, in writing, to the Attorney General:
(i) containing particulars of the circumstances in which the device was used, and
(ii) without affecting the generality of subparagraph (i), containing the same particulars, and specifying the same matters, as are required by section 19 (1) (b) in relation to the use of a listening device pursuant to a warrant granted under Part 4.
