I'd assume, given it was always going to go the council's way, there was a higher purpose to it.
Christ knows what but... would be rather surprised if this was the end of it.
(Then again, it's a small insignificant thing really. Does it really deserve any attention at all?)
I suspect it was character assassination ahead of the JR appeal (although in the end the second round came to late for that) and ahead of JR2. Imagine if it was found against the council and you could reference that even the council found against themselves. That would have been a good weapon in their war chest. Let's face it, with all the money they've spanked on litigation it was hardly a drop in the ocean in terms of cost to do it so well worth the effort and who knows it may have even uncovered something previously unknown to the SISU legal team.
Of course it could be an indication of just how weak SISU's argument is and they just need to throw shit in any direction hoping something sticks.
It also could be an indication of how personal this has become and it's purely been done for theatrical character assassination and nothing else. I guess we'll only find out how successful that was at the next election.
