Hard to see what sort of "personal injury, loss and damage" the captain could be claiming for, when to all intents and purposes, all she appeared to have done was exactly what we are all expected to do and paid to do as a Commander.
Unless...... there were some aspects of the diversion etc that have not been made public.
What about the other crew, were they not involved in whatever nefarious circumstances that have precipitated this high court action?
Also why wait so long if whatever it was that occurred, was so serious to merit High Court action? Unless that is the fastest speed that the HK legal system can cope with.
