The Willis Cup holders were at risk of being relegated to the Championship after their reserves, who scratched three games last term, were originally banned for 2016/17 following a rule breach.
However, Island clubs voted 17-1 in favour of a change to regulations at the league’s annual general meeting, meaning top tier sides no longer need to enter a reserve team.
They also passed a separate appeal, by 14 votes to five, to allow Scottish Reserves back into the league system.
