To confirm, this is your opinion and is not supported by any sort of facts.
The PL would not be finding City guilty of fraud albeit they could/would strongly infer it. Any ruling by the tribunal cannot be appealed outside of the PL environment, unless it is founded upon such completely egregious reasoning as to convince a commercial court to take it on, and even then, a commercial court has already ruled the PL have jurisdiction to hear the case, not them.
TLDR version, unless City put forth such evidence as to show completely incontrovertibly that everything was above board, the IC acknowledges it and openly ignores it, the case will end within the PL environment.
