I'm really curious about the consequences were the season to be called off prematurely. I've had a flick through the EFL's rules and, unsurprisingly, there isn't any guidelines that I can see relating to what happens in the extraordinary event that a season cannot be completed with regards to final league positions, promotions, relegations, etc.
That said,
Clause 6.1 clarifies that, "The League shall conduct
and in every respect control each Season football competitions, being both league and cup competitions...", which would seem to be sufficient to give them final say over what happens in the event the season needs to be cut short.
In the section on
Arbitration, Section 95.3 appears to indicate that clubs can only appeal against decisions of the League on grounds of, "ultra vires (including error of law); or irrationality; or procedural unfairness; and where the decision directly and foreseeably prejudices the interests of a person or persons who were in the contemplation of The League or Board." A good lawyer could presumably make a case on the grounds of irrationality or procedural unfairness (given the intrinsic subjectivity of those two terms), and obviously a relegation, or being denied the opportunity to be promoted, prejudices the interests of those clubs. This litigation would presumably take months to resolve - and I would imagine could spill over into
next season, too.
I don't think the league could even defend itself by saying, what else were we supposed to do, as, as far as I am aware, the party seeking what essentially amounts to an reversal or annulment of the decision, does not have to offer alternative courses of action. It simply has to show that the decision was unfair - which relegating a team despite it still having a chance to stay up, given the matches left to play, probably is.
