JUDGMENT
1 SPIGELMAN CJ: I agree with Sully J.
2 SULLY J: This is a Crown appeal brought by the Attorney General as of right pursuant to section 5F of the Criminal Appeal Act 1912 (NSW). The appeal challenges an interlocutory judgment given by his Honour Judge Woods QC on 10 September last. Mr. Kaddour and Mr. Turkmani, the respondents to the appeal, are currently standing trial before his Honour, sitting without a jury, upon a charge of having solicited the murder of one Albert Brikha. The interlocutory judgment against which the appeal has been brought by the Attorney General concerns some questions of public interest immunity privilege.
3 The relevant facts can be extracted, sufficiently for present purposes and as follows, from the written submissions of learned Counsel for the appellant:
"Both respondents are charged with soliciting the murder of Albert Brikha. The case alleged by the Crown may be summarised as follows.
On 4 July 1997 Brikha, a tow-truck driver, and John Assadourian, a tow-truck driver from a rival business, attended the scene of a motor vehicle accident . The two men argued and Assadourian invited Brikha to go to nearby bushes to settle their differences; Brikha accepted. Out of sight of witnesses at the scene of the accident, three shots were fired. Assadourian emerged from the bushes and departed from the scene. Brikha was found wounded by three bullets. Soon afterwards, Assadourian was charged with attempting to murder Brikha. Brikha was the key Crown witness. On 20 February 1998, whilst the committal proceedings against Assadourian were pending, Brikha was shot dead outside his house.
A police investigation ensued and inter alia focussed on people in the tow truck industry. An initial target was, of course, Assadourian. George Agoulian, an associate of Assadourian, was also investigated. One method used during the investigation was to have police informers engage Assadourian and Agoulian in conversation in circumstances where the conversation might be recorded and might disclose relevant evidence. Neither of the two respondents were targeted in this way (nor was anyone else targeted in this way, although others' conversation was monitored collaterally).
The Crown case is that the respondents, who also worked in the towing industry, solicited Anthoney Lo to murder Brikha. Lo has pleaded guilty to the murder of Brikha and is serving a sentence for that crime. Lo is now a Crown witness in the present case. He has given direct evidence that the respondents solicited him to murder Brikha.
Two police informers are to be called to give evidence in the ordinary way (i.e. to give evidence of things they saw, heard or otherwise perceived). At issue in this appeal is whether or not any witnesses can be questioned so as to ascertain which of them are the informers. (As the informers were identified in the judgment initially delivered in the presence of counsel for the accused, those counsel know the identities.)"
4 On 21 August last Det. Snr. Constable Robert Barnett was called to give evidence in the Crown case against the respondents. In cross-examination he was asked this question:
"Q. Was it part of your investigation - consider your answer again please - concerning Mr. Agoulian - did part of your investigation involve the sending in of non-police personnel to engage in conversation with George Agoulian in these premises?"
5 Det. Snr. Constable Barnett responded:
"I claim privilege on that."
6 This exchange triggered the making by the Commissioner of Police of applications to his Honour that certain lines of cross-examination be disallowed for reasons of public interest immunity.
7 Those applications were supported by three affidavits, one sworn by Mr. K. E. Moroney, a Deputy Commissioner of Police; and the other two sworn by Mr. Jeffrey Thomas Jarratt, another Deputy Commissioner of Police. Each of those three affidavits made reference to a "Confidential Statement", being a separate document marked as an exhibit to the particular individual affidavit. Each affidavit did not reproduce, of course, the contents of the Confidential Statement to which that affidavit referred; but the Confidential Statement itself was made available to the learned trial Judge; and has been made available to the members of this Court in connection with the hearing of the present appeal.
8 Each of the three affidavits asserts, put simply, two propositions, namely:
1. That Det. Snr. Constable Barnett has been asked a question in cross-examination "the answer to which may lead to the identification of an informer and as such is subject to a claim of public interest immunity" .
