As a retired solicitor I'm not so sure .
There was an earlier case which accepted that in principle a claim can be brought by one club against another and the commission specifically said that it may be possible for a club affected to bring a claim.
The big problem is the uncertainty.
Any such litigation would take years and years to come to trial ( interesting that West Ham settled out of court with Sheff U over the Tevez / Mascherano affair. )
My estimate would be that the litigation would drag on for at least 3 years.
That takes away the immediate threat of administration from Everton being unable to pay any damages against them.
However the uncertainty could lead any prospective buyer to conclude that a purchase of Everton was too fraught with difficulty and lead to administration if Moshiri is unable / unwilling to fund it.
I suspect that the outcome will be Moshiri having to massively reduce his asking price and the new owners doing a deal with affected clubs to prevent future litigation and give certainty
