The JR regarding the sale could be interesting. We might get to find out a time line of the sale, who approached who etc.
As for the price you can see the route SISU will take. They will point to the figures being thrown around when they expressed an interest (£10m for Higgs share via the formula, whatever silly amount it was for the matchday revenues), then show that against the sale price and then what Wasps claimed the lease to be worth a matter of weeks later.
Appreciate the value of ACL and the value of the lease aren't the same thing but it will still need to be shown how a company with an asset worth, was it £40m?, in Wasps prospectus was with under £6m. And of course why the original 50 year lease and the extension given to Wasps differ so greatly in price.
