Because what case could Burnley bring against the PL?
The case that the punishment the PL imposed on Everton didn't reflect the season that PSR was breached and therefore contributed to them getting relegated?
I've no idea what case they could take against Everton. And if there is one, can forest be sued. Can Chelsea and City?
Can one club sue another for a poor VAR decission that costs PL places and the millions that come with it.
These clubs are all memebers of a league, a league that specifically broke away from the football league for more self determination.
They all signed up to the rules. You get your chance to argue your corner against the league. Everton did that poorly and lost.
Arguing that case against other clubs who dont control any punishment is mad.
