Fees were brought in to prevent clubs appealing decisions even when they knew they had no chance of winning just to delay suspensions. You get the money back if the appeal is successful I believe.
As I said previously SFA set a precident when they said contact on Aluko was minimal and not enough to justify Aluko going down. Pawlet was similar situation. He did make the contact look a lot worse than it was and therefore is guilty of simulation. I just hope we see this applied to all the other teams in the league and we see an end to players throwing themselves to the ground at the slightest touch. Not holding my breath.
