I’m not sure I totally understand, but heres my attempt….!
Moshiri leant the club money at 0% for the stadium build.  He the tried to claim interest on the loans and put that against PSR.
As far as I can work out, Moshiri tried to claim at the hearing that even though he loaned the money at zero % for stadium loans, the money actually came from the R&M and Metro bank loans so he could claim them for PSR as they were part of the stadium build cost.  Moshiri claimed that if there had been no stadium build then he’d have paid the interest on these loans (as he had done in the past?)  anyway, so they should go against PSR.
the problem is, that they only had Moshiris word for this and the paperwork on the loans didn’t back him up.
or something
		
		
	 
Essentially what it was:
1. Everton borrowed a bunch of money for the stadium build.  Moshiri still needed more money to finish the stadium, so he was looking for more people willing to loan
2. It is more attractive for a lender to loan on a stadium that has zero loans, than one with 200 million in loans, so he put it in the books as just a "general funding" loan for Everton itself, rather than directly tied to the stadium. 
3. The interest on the loan is around 20 million per annum.  He then wanted to deduct that from our P&L.  The league said it wasnt for the stadium so it couldnt be deducted. 
He could have just stated it was a stadium loan from the start, and instead leant the club money at 0%, and it could have been deducted though it would have made it harder to find funding to finish the stadium.  It is purely in his choice of whether to record his 0% loan as for the stadium or for the club in paperwork.  Exact same money, same results, different accounting.
Essentially it IS a stadium loan, but Moshiri wanted the PL to view it one way, and potential lenders to view it another way.  As often is the case with taxes and accounting, the money serves the same purpose, costs the same, but HOW you write it down in the accounts makes all the difference in how it is viewed.  As anyone who runs a business knows, you can have the exact same 200k in income, and 100k in expenses, but you can end up with 70k in taxes or 20k in taxes purely based on how you write it down.
