I've just quickly read the full judgement and it makes interesting reading. Basically, Everton carried on spending on players despite the PL warning them they were breaching the Financial Sustainability Rules by continuing to do so.Everton then tried to claim a number of things should be used to reduce their FSR losses.
These included claiming for interest payments made on loans from Metro Bank that they said were part of the stadium development. However, the agreement with Metro was that these loans would be used purely for working capital. It was Moshiri who was funding the stadium development, interest free. The panel decided that Everton had tried to mislead the PL over this.
They also tried to claim back the 4% Levy on transfers, part of which goes to fund player pensions and some to youth development. They did this on the grounds that it's youth development and that this is regarded as 'good' expenditure. The panel rejected that view as Everton weren't spending it on youth development in their own club.
They tried to claim the £10m a year naming rights deal with Usmanov, which they didn't receive once sanctions were imposed on him. The panel rejected that as, although negotiations were well advanced, no contract had been signed.
There were other rather bizarre claims from Everton, such as not suing a player, which they felt would have added an extra £10m to their coffers had they done so, and overvaluing players they claim they could have sold at those prices but for Covid.
It's all really rather desperate stuff from Everton but the PL were insistent that a points deduction was the right sanction, whereas Everton were asking for a financial penalty as being more appropriate. The panel rejected Everton's argument on the grounds that they had a wealthy owner and a fine really wouldn't be a punishment. I think I can see where that's going!
