The SPFL have written to clubs in a bid to put contingency plans in place in the event the league can't be finished because of coronavirus.
The league was called last season after football was shut down in March because of the pandemic and it caused a civil war within Scottish football.
Hearts, Partick Thistle and Stranraer were all relegated after clubs voted to call the season, with Celtic, Dundee United, Raith Rovers and Cove Rangers earning promotion.
Rangers demanded an inquiry into the SPFL that was rejected by clubs and now the governing body want to ensure there is no repeat of the trouble.
They previously asked clubs for permission to call the season how they saw fit if rising Covid-19 cases caused football to be cancelled again.
That was rejected by the 42 members of the league and now the SPFL have sent a questionnaire to find out what each club thinks.
Some of those questions include how many league games must be played for a season to considered valid and whether they would now back the SPFL having the rights to call the season.
SPFL chief executive Neil Doncaster said: “When the SPFL rules were drawn up many years ago, no- one could have foreseen the impact which Covid-19 would have on our game.
“The fact that our rules did not expressly cover the situation where a season must be curtailed with a number of matches remaining to be played, caused a great deal of uncertainty and delay in reaching a resolution last season. No-one wants to see that repeated.
“Many of our clubs support the principle of drawing up a set of protocols long before we get to the situation where league positions understandably influence the individual approach of clubs to these difficult situations. However, the proposal to allow the board a clearly specified and limited degree of authority to take action if we are unable to complete the season did not have sufficient support in the summer.
“Given the ongoing challenges caused to sport worldwide by Covid-19, several clubs have now indicated they have changed their position.
"The board wishes to establish if a sufficient number of clubs now wish to revisit this issue, so we can significantly reduce the uncertainty and division that arose towards the end of last season.
“Those circumstances were caused by the need to curtail the season, make promotions and relegations and cancel the play-offs, all in a written resolution. As we know, this effectively meant asking members to vote for the relegation of their club and other clubs in circumstances where the season could not be completed, with all the issues this prompted. If there is sufficient support to secure an amendment to the SPFL Rules, then all clubs will know well in advance of any need to curtail the season what the outcome will be – so far as it concerns league positions, promotion, relegation, play-offs, fees and qualification for UEFA competitions.
“The questionnaire is designed to assist the Board in recommending a resolution to member clubs as a means of giving the SPFL Board the express power to deal with any further Covid-19 related disruption to Season 2020/21.”
