There realistically only two fair options. The poorest is the season is declared null and void and we start again in August.
The second and fairest is the season is played out later in the year and next season is amended in someway. If we start awarding titles, promotions and relegations in an incomplete season causes imbalances unless it's right across the board in each division. For eg promote two from the championship and not relegate causes more inequality in the Championship and downwards. Those who dont go down receive payments they would not be entitled to giving them an unfair advantage in seasons to come.
This is compounded if there would be enough games for teams to catch those above, but not having an opportunity to do. How would that be fair on those missing out. I fear litigation for some time to come if that was the case!!
