Not sure how I missed this but Burnley are taking on Everton through the courts over Everton's breaching of PSR (which resulted in Burnley being relegated). Burnley would have been saved had Everton been docked the points in the season they committed the breaches. The original PSR decision effectively granted Burnley permission to take them on in court if they wanted to.
They're suing Everton for £50m.
Beyond this individual case, there could be an important precedent set here for 115/130 FC. Needless to say, I hope Burnley win, but I suspect they won't. I think they know that and were hoping Everton might settle out of court.
Being pragmatic about it, I don't think Burnley should win this one. Although I'd agree it would be fair if they did, I think the legal bar they will have to clear is too high - they'd need to show Everton benefitted from a sporting perspective to the extent that they (Everton) would have been relegated had they not spent like they did (too nebulous to prove) or else that the rules should have imposed the penalty retrospectively (which is a hard argument because, by becoming shareholders of the Premier League, Burnley effectively signed up to accept those rules as they were).
So I don't see them winning, which is not to say that a subsequent case against 115/130 FC wouldn't succeed, as in their case the sporting advantage argument will probably be easier to make (especially for a team that twice finished 1 point behind them). In that respect, the decision may be helpful to the bigger clubs as the reasoning of any decision will help them to build cases against City if they are penalised.
