14 The evidence the subject of the second ground was tendered in the defence case. Its content is to be found in an email dated 13 January 2004, addressed from Ms Joanne Maestri to counsel for the appellant, attaching a copy of another email dated 27 November 2003, addressed to the then state Opposition spokesman for police. The attachment is a lengthy, closely typed document. Its substance appears to be a complaint about the handling by police of a matter Ms Maestri had reported, and contains a narrative setting out Ms Maestri's alleged dealings with, and financial exploitation by, a variety of individuals, including Mr Younan. She attributed to Mr Younan death threats made against her, and a reference by Mr Younan to "guns and making people disappear".
15 Further evidence sought to be adduced from Ms Maestri was contained in a statement made by her to police on 23 January 2004, headed "Threats made by Ray Younan". Ms Maestri alleged that, on 20 January 2004, at a coffee shop on the ground floor of the Downing Centre Court complex, Mr Younan again made a death threat against her. Counsel for the appellant told the judge that he wished to adduce this evidence and to supplement it by evidence from Ms Maestri that Mr Younan in early 2003 had indicated that he had possession of, and was willing to use, a gun.
16 The judge also rejected this evidence. For the purposes of this appeal it is unnecessary to distinguish between the two categories of evidence: essentially it was evidence that prior to June 2003, Mr Younan had, or had access to, a firearm or firearms.
17 Unless the evidence was relevant, it was not admissible: Evidence Act 1995, s56. Evidence is relevant where, if it is accepted, it could rationally affect (directly or indirectly) the assessment of the probability of the existence of a fact in issue in the proceeding: Evidence Act s55(1).
18 To resolve the issue raised on the appeal it is necessary to identify the fact in issue the probability of the existence of which it is said could rationally be affected by the evidence that, within six months prior to the events in question, Mr Younan had been seen, or had been known to be, in possession of a firearm: that is, that he had, or had access to, a firearm or firearms.
19 The factual issues in dispute in the trial were confined to those raised by the appellant's contention that his act in shooting Mr Younan was an act carried out in self-defence. There was no issue about whether or not, on 7 June, Mr Younan was in possession of a firearm: that question simply did not arise. If it had, evidence that, on previous occasions he had carried, or had suggested that he had access to, firearms, may, if it met the tests imposed by ss97(1) and 101(2) of the Evidence Act, have been admitted as tendency evidence. The Crown submitted that it was only by that route that the evidence could have become admissible, that that was expressly disclaimed by trial counsel, and that the prerequisites to its admission had not been met.
20 In my opinion, the question of the admission of the evidence as tendency evidence is a false issue. Any tendency on the part of Mr Younan to possess or use firearms did not ever emerge as an issue in the trial.
21 All of the rejected evidence was said (on behalf of the appellant) to go to the questions raised by the issue of self-defence. A "defence" of self-defence is provided for by s418 of the Crimes Act 1900, which is in the following terms:
