More information is available in this statement by Garden Court Chambers. The settled civil claims were for misfeasance in public office and relate only to damage caused by the cover-up and not the disaster itself. As the statement points out - "the cover up was deliberate, orchestrated and thoroughly dishonest" and was "maintained for nearly 30 years."
The Garden Court statement concludesby pressing the case for a duty of candour to be placed on public bodies - (previous post) - and for bereaved families to have adequate public funding to enable them to be effectively represented at an inquiry or inquest into the death of their relatives.
For discussion of the elements of the tort of misfeasance in public office see Three Rivers District Council v Governor of the Bank of England  UKHL 33. Note: The stated law was not intended to be an "essay on the tort" but it stated the ingredients of the tort so far as material to the the pleadings in the actual case.
