Impossible to say for sure, but it blows the defence Fife have been running (that SP is a bigot who deserved punishment) out of the water. Their only possible defence now is to argue that they've followed the correct process in dealing with these allegations, but I don't think that flies and, in any case, it fails to take into account their failure to provide a single sex changing room for women, as required by law.
Upton can stick with the defence arguments to date, but he will be on his own if he does so. As Michael Foran says, NHS Fife agreeing to joint representation with Upton and funding his defence was a huge mistake. They assumed that their interests were identical, which was only true if SP didn't have a case. I cannot see any way Fife can now defend their position without abandoning Upton, and I don't see any way Upton can defend his position without attacking Fife.
I look forward to seeing what happens when the hearing gets under way.
