I agree that a worrying line has been crossed. But why?
Trying to look at it from the perspective of the injured and bereaved, I did hear the operator's spokesman on the radio the other day saying they were doing everything possible to help the families and had already paid out £500,000 to them.
Quite aside from the four dead, I doubt many of those on board have worked since - and £500k between 16 offshore workers over a 2 year period wouldn't even cover loss of earnings
If the system isn't better at getting a swift and fair settlement (as if any settlement could come close) for the innocent victims of a tragedy like this, then I suppose its not entirely surprising if the courts are called upon to intervene to this uncomfortable degree in poring over the detail of the events.
