"The aim of the legal action is not yet clear but it is likely Sisu would like to see the deal undone or for compensation to be paid for the negative impact on the football club"
even if (and its a huge if) SISU won JR2 I am not sure how the deal could be unpicked. The court could require CCC to revisit the decision on the sale of its 50% but I doubt it could make the Charity do that, and in any case they may well reach the same decision. It could penalise CCC but any payment of fine would not go to SISU, so even if the shares or lease was sold for undervalue no funds to SISU from the court case .
Then SISU take new court action for damages. They would have to prove they had a right to be offered a deal, that they had a connection to the stadium that gave that right, that it was this decision to sell to Wasps that damaged the club at the time (2014) and since, that they had made their intentions clear etc. They could not I think argue that the sale to Wasps was responsible for the losses before Oct 2014 so that knocks a big hole in any compensation claim
of course by that time, Oct 2014, SISU had broken the CCFC right to occupy the stadium and moved the club away. They had returned as a day renter with limited access to the stadium, their owner had said they would not interfere with the share sale, and the directors past and present repeatedly stated they were going to build their own stadium or partner up at BPA. They had of course argued that there was no value in ACL whilst proceeding with JR1. Would a court really be persuaded that the clubs fall from grace, its financial mess, was down to the sale of the shares and a lease extension? The rights to compensation look to be even more tenuous than under JR1
