I just don't understand how the efl could sue the pl if they null and void the season. What would their argument in court be against the pl? They can't blame the pl for not being able to finish the season, how are the culpable? They’re not allowed to play matches until the Government changes the rules and there will be a date, either because of player’s contracts ending or the impact of future seasons/tournaments that will deem it impossible to complete the season. Even if they thought they had a case would they have the money to sue the pl?
Also, if the pl can't be concluded then there's no way the efl can finish all of their fixtures. They might not be able to even if the pl does, they haven't got the same resources. How do they decide who gets promoted then? That’s the time when the law suits will arise, by clubs who have had decisions made against based upon forecasts or table as it stands scenarios. Then there would be an argument about fairness.
