(This may only apply to the UK).
Several years ago, when Health & Safety and other legislation was coming into force, I attended several 'senior management' seminars. It was emphasised strongly that liability for breaches lay not only on corporations/organisations (mine was a police force) but also on individual managers/those with responsibility.
I don't know whether there are any/many cases of individuals being held liable, but I am aware that in lawsuits individuals are named as defendants along with organisations.
My amateur view is that in WT land, it has been established by the ARC that elders are in a position of authority (despite the best efforts of Ms Applewhite) and thus are liable to be sued. There could be an argument that WT (in its various forms) has vicarious liability for the actions of its agents/officers (elders, etc.) but I think that there is sufficient case law in various jurisdictions to indicate that elders etc. are personally liable.
