There is no basis for it, as every league that went for null and void had no legal action and no difficulties relating to legalism in restarting.
It literally had no impacton any league where cancellation was taken. A complete red flag. Again without trying to be wise after the event, I did point this out at the time as well.
Only one league went null and void to the best of my knowledge, the rest where settled with promotion relegation
The truth is no one knows, restart was average at best, many hailed it as a success. You cannot say with certainty, your method would have been better, there in all likelihood would have been at minimum legal attempts from Leeds, WBA, probably Liverpool and most teams not impact by threat of relegation when TV rights were not paid.
That discussion needs to be parked the question is what happens with future hiatus due to this poxy covid and hellish government
