Yes, from everything I've read, where a number of people (including a couple of lawyers), have asserted this and no one has contradicted them, I believe that to be true. You do all know that SP is the one bringing this case against NHS Fife/ Upton, I assume? It's not them taking her to court, she's dragged them here so that everyone can see the insanity of the situation.
Her costs are being underwritten by someone unknown, presumably someone with funds who's looked at the case and the benefits to be gained from winning it and taken the risk of funding it. Though given all that NC and team have dug up, there doesn't seem to be any realistic risk of losing.
