I would think that if the cup finalists finish in the top 4 and 5th place becomes a european berth...AND by some miracle scotland are awarded a fair play berth... it will go to whoever tops the fair play league... if that team has already qualified through league position it will go to whoever is next on the list.
I am pretty sure celtic topped the fair play league and we were second last year, we got the award as celtic qualified through league position.
And for arguments sake, on current standings... Kilmarnock are in pole position for a fair play spot, closely followed by St Johnstone, with Accies and Falkirk trailing
