40 As part of this submission, counsel challenged Detective Sergeant Solomon's evidence concerning s 464B,[13] and the judge's finding that 'at the time [it] was not the strategy of the [Petra] taskforce' to utilise s 464B to interview the appellant about the Hodson murders.[14] In so submitting, counsel referred to the course of the conversations between Detective Sergeant Solomon and H and that, as counsel submitted, H was desperate to get the appellant home to resume their life together. Counsel submitted that the police must be taken to have known that the prospect of the appellant entering into a 'deal' would involve him discussing the Abbey murders, in aid of his earlier release home. As to that, counsel referred to H's evidence that the police said they were only interested in the Hodsons, they did not specifically talk to her about the Abbeys, that they spoke about assisting in relation to the Hodsons and, as to the Abbeys, that he would have to plead to that, and that representations could be made as to a lighter sentence on account of assistance for the Hodsons. Counsel accepted that the police had not asked H to speak to the appellant about the Abbey matter, but submitted that it was plain there would be discussion about the strength of that case. Counsel submitted that for these reasons, and the reasons advanced at trial, the evidence should have been excluded. He referred without further elaboration to Tofilau v The Queen,[15] Em v The Queen,[16] and R v Swaffield.[17]
