Where a trade union proposes to transfer its engagements to another trade union and an alteration of the rules of the transferee union is necessary to give effect to provisions in the instrument of transfer, the committee of management or other governing body of that union may by memorandum in writing alter the rules of that union so far as is necessary to give effect to those provisions.
An alteration of the rules of a trade union under subsection (1) shall not take effect unless or until the instrument of transfer takes effect.
The provisions of subsection (1) have effect, where they apply, notwithstanding anything in the rules of the union.
