197 As to the first issue concerning dominant purpose, my reasons for finding error are these. First, Mr Rayney did not give or play any of the original recordings to his lawyers, and he did not seek or obtain legal advice on them. This is of significance in that, despite the Category 2 Files having been seized by the police on 20 September 2007, Mr Rayney retained the original recordings until he destroyed them by deliberately throwing out the dictaphone 'over a week after he created the Category 2 Files' [54]. Secondly, the contents of the original recordings, which are summarised in schedule 4 to these reasons, do not reveal any statements by any party to any recorded conversation, or any discussion between the parties to any recorded conversation, in respect of which Mr Rayney could reasonably have sought legal advice, either in the defence of anticipated criminal proceedings against him in connection with the death of his wife or at all. The content of each original recording (in particular, the subject matter and any issues raised by Mr Rayney or his responses to the third party) is relevant in determining Mr Rayney's dominant purpose when the communication in question occurred. Thirdly, the conversations appear to have been recorded without any discrimination as to the possible significance or relevance of each conversation. This is important because most of the conversations were with police officers and there was no evidence that Mr Rayney recorded all of his telephone conversations with the police between 7 August 2007 and 20 September 2007. Fourthly, the matters to which I have referred indicate, objectively, that Mr Rayney's dominant purpose in participating in the conversations and recording them was not to put them before a lawyer with the object of obtaining legal advice or for preparation or use in the defence of anticipated criminal proceedings against him. Rather, the objective probabilities, based on the matters to which I have referred, and the fact that Mr Rayney knew the conversations were being recorded but the other parties did not, are that Mr Rayney's dominant purpose in participating in the conversations and recording them was to assess later whether anything said by any party might be useful or advantageous to him, as matters developed in the course of the police investigation into his wife's death.
