72.—(1) This Part applies to a trade union which is in whole or part an association or combination of other unions as if the individual members of the component unions were members of that union and not of the component unions.
But nothing in this Part prevents a component union from collecting contributions on behalf of the association or combination from such of its members as are contributors to the political fund of the association or combination.
(2) This Part applies with the necessary modifications in relation to an unincorporated employers' association as it applies in relation to a trade union.
