Seems a curiously non-standard process to me. I'd always assumed that the way that Coroner's worked was the same everywhere, I had no idea there was so much apparent variation. Then again I've only ever been to one inquest, and only then because I had a personal interest in the accident, having seen it happen and been one of the first on scene. I, wrongly it seems, assumed they all worked in the same way, to the same standards and procedures.
