you've got to be kidding. Where was the potential sale advertised? It was a deal done behind closed doors.
Legally CCFC's actions didn't disqualify them from being a potential buyer.
Council's responsibility was to maximize any potential return on a "public" asset - not operate behind closed doors with a single buyer they seemed to have pursued themselves for a considerable period before the deal went through. Provisional meetings were reported to have taken up to 12 months earlier - plenty of time to market the stadium to other potential buyers.
CCFC's actions may not have LEGALLY, prevented them from bidding, but there was no way they were going to be considered by the seller. (And yes, that's where it becomes a shit show)
As far as ACL/CCC/Higgs Trust were concerned, SISU had become untrustworthy, and the clubs announcement that they intended to build a new stadium, not to mention the renaging on a legal tenancy agreement, effectively gave the owners a reason to ignore them. (Hence no post sale legal action from SISU)
We can argue about the moral conduct of all concerned for as long as you like, but we are where we are.
Ironically, it looks like we could be entering another fight for the Arena ownership if Wasps can't find a sugar daddy very quickly.
And this time the council will have next to no say.
And it would be interesting to see what Wasps valuation of the Arena is, and what SISU would be prepared to pay, not to mention what other potential buyers could muddy the waters.
