Sligo Rovers say they sternly object to the format for a return to play in the SSE Airtricity Premier Division.
Play will resume on July 31st, with the season truncated to 18-games per team.
Promotion and relegation will remain as normal with one up and one down automatically, and a playoff to decide the other spot.
Sligo believe the format is "grossly unfair and unjust and they do not see the matter as closed.
