Please see my comments to
@MoutsGoat which cover this.
The Board of the PL has the power to examine or enquire into any suspected breach of the rules. They also have the power to impose penalties. The "guilty" parties then have the right to appeal and to go to arbitration if necessary and there's the appropriate criteria for doing so.
Usmanov knew before acquiring Moshiri's shares in R&W holdings that there would be no change in Kroenke's position re R&W's ability to be involved in the management of Arsenal or acquire board representation.
The point I'm making in all of this (and I agree with you no-one really knows Usmanov's intentions - even though "his people" are adamant he will retain his interest in Arsenal) is that if he was looking to divest from Arsenal and re-invest alongside Moshiri, then it is the most unusual and illogical way of doing it - a method that someone of his experience and access to professional resources would never consider doing, certainly never be advised to do it in this manner particularly in the prospect of a potential breach of rules and my final comment (ii) below.
Two final thoughts - (i) as close as Moshiri and Usmanov are, I think the events of the last few months are driven solely by Moshiri's desire to build a football club of his own accord, and (ii) perhaps more pertinently - there's no way Kroenke would acquire Usmanov's shares in the knowledge that Usmanov was then going to fund a competing club that had the potential to remove his club Arsenal from their eminent position - you just do not allow an adversary the opportunity to do something like that. Faced with this the only way Usmanov could sell would be to sell to a third party. The third party would recognise immediately the threat of Usmanov investing in Everton and draw the same conclusion.
Usmanov is locked into the position he holds. He may be very happy to be locked into that position, but even if he is not, it's almost impossible to conceive a way of divesting from Arsenal and reinvesting in another PL club.
