I wonder if it is to say there IS gonna be an inquest (and therefore count in a bloody great delay)
otherwise he releases the body along with a death certificate and the funeral can go ahead (usual delay 7 d)
For a lot of hospital deaths - they know who has died, they know where he died and why. If not even the relatives ring up the coroner and demand an inquest.
I am not sure if they do an awful lot inquests I mean
In the Gibraltar SAS inquests around 30y ago - Death on the Rock and all that stuff - There was so much security fol-de-rol that the IRA lawyer - oops lawyer for the dead men and woman - said, all you are gonna find is that these people are dead - but we know that anyway !
