So I am ignoring your first response as it completely missed the point, other than to say:
Research for yourself the requirement to report fraud rather than ask me to justify it. I freely admit I may be wrong about anything, but you think I am wrong, show me why.
Imho, the SFO isn't going to get involved if there is an ongoing civil case which will determine if there has been a fraud or not. Why would they? They can wait until it's finished, review the evidence presented in the report and then decide whether or not to proceed on the basis of a higher level of proof. I doubt they have the time or resources just to open cases based on what is in the press.
And now your second response.
They haven't "chickened" out of using the word fraud. There is no need to. They have followed their procedure and simply referred to the IC a list of rules they allege have been breached.
And the reason it's taking so long? Every legal person in here said it would take 2, 3, 4 years and that is what is happening. Simply put, the PL has brought forward a complicated case.
Also, I never said I thought the PL themselves think they will prove these allegations. My hypothesis is that the club put them in a position where they had to shit or get off the can. And they chose to shit.
