Apparently:
For Hearts' 14-14-14 plan to pass, it would require nine of the 12 Premiership clubs to vote in favour, along with eight in the Championship and 15 across Leagues One and Two.
A 14-14-16 model - which would include Lowland League champions Kelty and Highland counterparts Brora - needs the approval of 11 of the 12 Premiership clubs, 17 in total from the top flight and Championship, and 32 of the current 42 in all divisions.
