Technically its actually the board of the SPL/SPFL that has to vote on the transfer of membership. In our case the board of the SPL shat it and decided to make up the rules as they go along and let the clubs vote on it rather than the board. In Hearts case, assuming the board dont shite themselves again, it will be the board that vote on the transfer of membership (3 Premiership chairmen, 1 Championship chairman, 1 League One chairman, 1 League Two chairman and Neil Doncaster). In Hearts case, the board would be expected, by any reasonable person, to accept the membership transfer and demote Hearts to League Two, since the bodies have now merged.
