It is now necessary for me to review my earlier ruling that the accused should be tried together. The evidence of [the appellant's] convictions is relevant in Mr Marchesano's defence of the case against him, as is the other evidence of violence to which I have referred.
The State does not contend that all of that evidence is admissible in the State's case against [the appellant]. The only evidence that Mr Marchesano wishes to lead that the State contends is admissible in the State's case against [the appellant] is, first, evidence from the witness Tessa Smillie that [the appellant] threatened to harm her if she told police what had happened to [the deceased].
Secondly, evidence from Mr Gillmore of a threat by [the appellant] against Mr Gillmore in prison in May 2014, to which I have referred; and thirdly, evidence from the witness Barry Harding concerning a threat when [the appellant] requested Mr Harding arrange the borrowing of Paul Screaigh's Hilux ute in November 2013.
The State contends that the first and second pieces of evidence demonstrated consciousness of guilt. The State contends that the third piece of evidence shows that [the appellant] was involved in the hiding of evidence that [the deceased] had been killed.
It follows that the bulk of the evidence that Mr Marchesano intends to lead in the defence of the State's case against him is not admissible in the State's case against [the appellant].
...
I need to bear in mind not only the evidence which Mr Marchesano wishes to adduce in the defence of the State's case against him, but also that in its case against Mr Marchesano, the State will adduce evidence that in an interview by police officers, Mr Marchesano admitted involvement in the killing of [the deceased] and said that he was involved because [the appellant] threatened to kill Mr Marchesano and members of his family if he did not participate in the killing of [the deceased]. That evidence is admissible against Mr Marchesano, but not against [the appellant].
It is my view that the members of the jury will be able to understand and apply a direction that evidence of what Mr Marchesano said in his interview by police officers is admissible in the State's case against Mr Marchesano, but is not evidence against [the appellant].
I also consider that the members of the jury will be able to understand and apply a direction that the evidence of [the appellant's] propensity for violence and threats and to possess firearms is to be considered by them in Mr Marchesano's defence of the State's case against him, as evidence that it is less likely that Mr Marchesano did the act which caused [the deceased's] death, but that the members of the jury are not to consider that evidence in the State's case against [the appellant].
I have had regard to the combination of the evidence of what Mr Marchesano said in his evidence and also of the evidence of violence and threats and possession of firearms. I am satisfied that the limitations on the relevance of that evidence, to which I have referred, do not require the members of the jury to perform a mental feat that would be beyond them.
I consider that the legal principles are capable of being understood and applied by the members of the jury. I conclude that notwithstanding my ruling that in the defence of the State's case against him, Mr Marchesano can adduce evidence of [the appellant's] propensity for violence and threats and to possess firearms, that [the appellant] will not be prejudiced in the trial.
I have reached that conclusion because I am satisfied that the members of the jury will be able to understand and apply a direction that some evidence relevant to the prosecution and defence case of the case against Mr Marchesano is not admissible in the State's case against [the appellant]. I rule that the trial against the two accused should continue on the one indictment (ts 482 - 484).
