57.—(1) The trade union’s rules must provide—
(a)that payments in the furtherance of the political objects to which this Part applies shall be made out of a separate fund (the “political fund” of the union);
(b)that a member of the union who is not a contributor (see Article 59) shall not be under any obligation to contribute to it;
(c)that a member shall not by reason of not being a contributor—
(i)be excluded from any benefits of the union, or
(ii)be placed in any respect either directly or indirectly under a disability or at a disadvantage as compared with other members of the union (except in relation to the control or management of the political fund); and
(d)that contribution to the political fund shall not be made a condition for admission to the union.
(2) A member of a trade union who claims that he is aggrieved by a breach of any rule made in pursuance of this Article may complain to the Certification Officer.
(3) Where, after giving the member and a representative of the union an opportunity of being heard, the Certification Officer considers that a breach has been committed, he may make such order for remedying the breach as he thinks just under the circumstances.
(4) Any such order may, if a county court so orders, be enforced in the same way as an order of that court.
