The best way to describe it is that the legal entitlement to own the Property Options transferred from KM to the Prince on the date of the Court Judgement 16 October 2019. Knowing that there was likely to be a challenge in the form of an Appeal but also possibly taking into account valuation of the PO's issues Justice Fancourt gave a timescale to 1st July 2020 to complete the process. Its my view that KM's rights as owner to the PO's were transferred on 16 October 2019 by Court Order. For that reason KM's only requirement with regard to the PO's is to complete the sale. In other words he's in legal limbo. He has no legal ownership of the PO's and his only recourse is to get the best price possible.
That doesn't apply to the Kop Land sites which were not part of the Judgement. KM owns these and continues to own them. He can keep them and is not required to legally sell them onto the Club. This explains why KM was able to board off the Boundary Corner immediately following the Judgement restricting Club access.
