It is now six years since Singh J and the Lord Chief Justice considered the relationship between Accident Investigation Branch investigations (Rail, Air & Marine) and coroners’ inquests in ‘the Norfolk case’.[1] In that instance the issue was whether a coroner had the power to order the Air Accidents Investigation Branch (“AAIB”) to disclose a cockpit voice and flight data recorder. The Divisional Court said ‘no’. But that’s not important right now…
What was more interesting was what Singh J[2] said about a coroner – who was not an expert in the field – not being required or permitted to “go over the same ground” as an AIB. Lord Thomas agreed and bemoaned the tendency “for different independent bodies … to investigate, either successively or at the same time, the same matter.” He concluded that, if coroners did not defer to AIBs which had the greatest expertise, then public money would be wasted. In the absence of “credible evidence that the investigation into an accident is incomplete, flawed or deficient” then a coroner had no business re-investigating matters covered by the independent investigation of the AAIB.
What then should a coroner do in these circumstances? According to Lord Thomas either: (a) adjourn pending publication of the AIB report or (b) proceed on the assumption that the reasons for the crash will be determined by that report and the issue treated as outside the scope of the Inquest.
