His Honour concluded that the desirability of admitting the evidence outweighed the undesirability of admitting evidence that had been obtained in the way in which the evidence was obtained. There is no challenge to this decision.
22 On appeal, Mr Game SC, senior counsel for Kane, submitted that Kane's initial arrest and detention were unlawful (and hence the evidence of the first interview was unlawfully obtained) on two bases.
23 Firstly, he submitted that the arrest was unlawful because, when Smith arrested Kane, he told him merely that he was doing so "in view of the information that we have received, regarding the death of Mr Tonks". He argued that Smith should have told Kane that he was being arrested on a charge of murder and his failure to do so rendered the arrest unlawful.
24 Secondly, Mr Game submitted that the detention of Kane was and continued to be unlawful because at the time of the arrest Smith did not have the intention of taking Kane before a magistrate and charging him as soon as practicable.
25 In arguing the first point, Mr Game accepted that the lawfulness of the arrest was to be determined by the principles expressed in Christie v Leachinsky [1947] AC 573 by Viscount Simon (at 587-588). Relevantly, his Lordship said:
"(1) If a policeman arrests without warrant upon reasonable suspicion of felony, or of other crime of a sort which does not require a warrant, he must in ordinary circumstances inform the person arrested of the true ground of arrest. He is not entitled to keep the reason to himself or to give a reason which is not the true reason. In other words, a citizen is entitled to know on what charge or on suspicion of what crime he is seized.
(2) If the citizen is not so informed but is nevertheless seized, the policeman, apart from certain exceptions, is liable for false imprisonment.
(3) The requirement that the person arrested should be informed of the reason why he is seized naturally does not exist if the circumstances are such that he must know the general nature of the alleged offence for which he is detained.
(4) The requirement that he should be so informed does not mean a technical or precise language need be used. The matter is a matter of substance, and turns on the elementary proposition that in this country a person is, prima facie, entitled to his freedom and is only required to submit to restraints on his freedom if he knows in substance the reason why it is claimed that this restraint should be imposed.
(5) …"
26 Mr Game argued, in effect, that Kane did not, in substance, know the reason why he was arrested.
27 In my view, this submission cannot be accepted. Immediately prior to telling Kane that he was under arrest in view of the information the police had received regarding the death of the deceased, Smith referred to that information in the following terms:
"Mr Kane, as I have already told you, I am Detective Sergeant Smith and this is Detective Perry. We are attached to the Major Crime Squad North at Chatswood. We are investigating the death of Mr Wayne Tonks, a 35 year old high school teacher who was murdered at his home unit at Artarmon on the weekend of the 19th, 20th May 1990. We have received information that you may have some knowledge of the death of Mr Tonks."
28 Accordingly, Smith made it quite plain to Kane that the deceased had been murdered, that the police had received information that Kane might have some knowledge as to his death (and, implicitly, the murder) and in view of that information Kane was being arrested. That being so, Kane knew, in substance, that he was being arrested on a charge of murder. I would not uphold the arguments advanced on this issue on Kane's behalf.
29 Mr Game submitted that Barr J had decided only the question whether Smith intended to delay charging Kane until he completed questioning him and he argued that this was not the correct question. He submitted that the correct question was whether, when arresting Kane, Smith had a concurrent intention to take him before a magistrate to be charged as soon as practicable.
30 Mr Game pointed to the fact that Smith had testified that, at the time of the arrest, he intended to question Kane and he did not intend to charge him until he had completed the questioning. Barr J rejected this evidence. As mentioned, his Honour found that, when Smith arrived at Kane's parents' home on the morning of 16 May 1999, he intended to charge Kane. Mr Game submitted, however, that it was to be inferred from Smith's evidence that he did not intend to charge Kane as soon as practicable.
31 I do not accept these submissions. Three points can be made. Firstly, there was no finding that Smith did not intend to charge Kane as soon as practicable (albeit that his Honour was not asked to make such a finding). Secondly, it was not proved that, at the time of the arrest, Smith did not intend to charge Kane as soon as practicable. Such a conclusion inevitably follows from the absence of direct evidence on the issue together with the findings that Smith had decided to charge Kane with murder when he arrested him and that Kane had not proved that, at the time of the arrest, Smith intended to delay charging him. Thirdly, it is implicit in Barr J's findings that at the time of the arrest Smith intended to charge Kane as soon as practicable.
32 In the circumstances I would not uphold the first ground of appeal.
33 I turn now to the second ground of appeal. This challenges the directions given by Barr J to the jury in regard to common purpose. In this regard it is necessary first to set out briefly the competing versions before the jury.
34 As I have mentioned, the Crown case was based on the second police interview and the evidence of Bedelia Dali and Mrs Unger. According to Ms Dali, Kane told her that when he and Andrew were aged 16 Andrew had told him that he had been raped by a man. Andrew asked Kane to go with him to the man's home to murder him. The two had gone to the man's unit, were invited in and were given some drinks. They bashed the man, tied him up and placed a plastic bag over his head. When Kane and Andrew left the unit they went to McDonalds to change their blood stained clothing into some clean clothes which they had taken with them. Kane told her that he and Andrew had together murdered the man.
35 Similar evidence was given by Mrs Unger.
36 In the second police interview Kane told the police that he and Andrew had been given spiked drinks by the deceased and another man at the deceased's unit in Artarmon. Kane was tied up and was anally raped. He was compelled to perform oral sex on the deceased. Thereafter, he and Andrew discussed getting revenge for what the deceased had done. He was aware that some film or photographs had been taken of him and wanted to find out if the film or photographs were in the deceased's unit. He also wanted to give the deceased a hiding. For this reason he took a small baseball bat which he owned and some tape to the flat. He and Andrew gained entry to the unit by telling the deceased that they wanted a good time. After demanding the handing over of film he and Andrew commenced to hit the deceased. He said that he had tied the deceased's hands and feet with the tape but could not remember tying his knees or putting tape over his mouth and eyes. He said that he could not remember placing a bag over the deceased's head and could not remember Andrew doing that. Eventually he said to Andrew "let's get out of here" and Andrew left right away. They arrived at Artarmon station together, having walked there.
37 The case against Kane, based on the testimony of Ms Dali and Mrs Unger and on the police interview, was that either he, Kane, had placed the bag on the deceased's head or Andrew had done so in Kane's presence. If Kane had placed the bag over the deceased's head he was the murderer. If Andrew had done that, this was part of the plan, Kane having agreed to help Andrew in killing the deceased.
38 Kane's second ground of appeal is directed principally against written directions given by Barr J to the jury.
39 These written directions were supplemented by his Honour in considerable detail in the course of his oral directions. Moreover, his Honour said in regard to the written directions:
"I want to give you a particular warning about [the written directions.] [They are] intended for your assistance, but [they are] not intended to be a substitute for the complete directions that I give you orally. There is always a danger that when important directions are summarised in the very short way that these directions on the document I have given you have been that there will be a temptation to stop listening to anything else I say. You must avoid that temptation. The directions I have given you are only skeletal. They do not attempt to cover everything, every important thing that I shall say to you. You should continue to heed every word that I say to you."
40 In the circumstances, the written directions cannot be looked at alone. They must be seen in context and in particular in the context of the oral directions given by Barr J.
41 The written directions asserted that, before the jury could convict Kane of murder, they needed to be satisfied beyond reasonable doubt that any of the following things happened, namely:
"2.1 Because the accused alone or jointly with Andrew did the act causing death intending to kill the deceased or do him grievous bodily harm; or
2.2 Because Andrew did the act causing death either pursuant to an agreement with the accused to kill the deceased or pursuant to an agreement to attack the deceased where the accused contemplated the death of the deceased as a possible result; or
2.3 Because Andrew did the act causing death intending to kill the deceased or do him grievous bodily harm and the accused, knowing what Andrew was doing and what his intention was, intentionally assisted or encouraged him to do the act causing death".
