Coroners Inquiry
A Coroner is required to 'explore facts' to determine the probable cause of any 'unnatural death. One would assume they are 'independent' and able to use whatever information is available to come to a decision. The use of CI by the defendants team was part of a 'legal' process to show doubt on the prosecutions case which was in itself was poorly constituted, and probably not the correct charge to have been made.
A Coroner has the opportunity to look at the 'facts' and engage with information from outside independent bodies to assist in a fair inquiry.
I suspect that a Coroner will be very wary of being influenced by 'clouding issues' and more interested in exploring how this sad and tragic accident happened in what is supposed to be a highly regulated regime. It may well be that the more basic details of the situation will be explored in greater detail, and a honest and reasonable cause attributed to this accident.
