The thought just occurred to me that any BASSA member here could clarify the issue regarding claimants exposure to costs should BASSA lose in the High Court.
They have an email address at their lawyers, who I assume would be happy to answer the question for you:
[email protected]
I'm sure many people would be interested in hearing who would be liable for the significant costs in the event of a loss.
(Oh and that's also the address the poor things should use when they get sick or hurt having to work under imposition).
