I am sceptical about the question of costs. They may well have been under-estimated, as appears to be the case from the discussion. If there are costs, these will be passed on ultimately to the people who are bearing the liability. It is not possible to deal with everything on paper and there are different degrees of injury. There is a view that there is great unanimity among medical experts. However, my experience of medical experts in the past has been different. They can often draw different conclusions from the same data, even on the basis of having been given the best diagnosis. That element might not be as simple as it appears.
