I think ( if my calculations are correct ), it was pretty clear the panel should clear City early on during the hearing and this was probably obvious within a few days.
FYI: You're allowed to lose up to £105m over a rolling 3 year period. Normally, you would just add up 3 consecutive years of P&L to get this figure. However you can adjust the P&L by removing depreciation, charitable donations, youth development and women's football development expenditure. Your P&L then becomes your Adjusted Earnings which are added up and compared to the £105m figure.
At some point the Premier League would have shown their sums to the panel re Allegation 4 and I suspect they were based on City's P&L and they hadn't calculated the Adjusted Earnings at all.
How many nobheads at the EPL would know City spent £120m expanding the stadium during the period in question and had sufficient depreciation listed in their accounts to adjust their earnings? Once the AE is calculated the whole case is futile.
I'm sure Lord Pannick and Co will have calculated the AE properly and pointed this out. If my calculations are correct, the case collapses at this point.
I'm pretty certain this is the biggest hole in the whole PSR case ie even if City have done all the nasty things they're accused of, they still don't break PSR.
We know from Michael Samuel's article that the Premier League were not ready to charge City, and this case was rushed through at the behest of Daniel Levy. They obviously made mistakes with the original statement. So they probably didn't check what they were accusing City of properly.
I suspect (because City were profitable at the time), that their Adjusted Earnings weren't calculated at the time and that only the normal P&L was looked at instead. If City were profitable, and they're nowhere near losing money, the AE figure didn't matter, why calculate it?
I therefore think that the EPL based their case on City's P&L from 2013-2018 rather than their Adjusted Earnings. This assumption is the problem. City would fail PSR if the calculations were just their P&L added up.
All the figures I used are based on the Premier League rules in force at the time, the statement the Premier League released and public information at Companies House showing City's accounts.
My conclusion is this entire case is bollocks and would have been immediately obvious, yet these lawyers need to justify their invoices, so careful consideration continued etc. All the latest smoke and mirrors is about this and getting the PR right.
