I feel it is because that we have made use of a loophole, perhaps not 100% ethical, but a loophole nonetheless which can be legally exploited and which was overlooked by the FL.
The FL know that they cannot fight this legally, but if they allow us to exploit it and sfc have the -10 overturned the FL will have all sorts of flak come down on them from a great height from other clubs that could have used this flaw to their benefit. Plus other clubs ie Brentford who deem it as cheating.
As I see it, a compromise is the only solution and then the FL will have to review and change their rules and regs. God knows what the compromise would be.
