(1)Subject to the provisions of this section, every worker shall have the right not to be—
(a)excluded from membership,
(b)expelled from membership,
of a trade union or a branch or section of a trade union by way of arbitrary or unreasonable discrimination.
(2)The exclusion or expulsion of a worker from membership of a union, branch or section shall not be deemed to be arbitrary or unreasonable if the worker is of a description different from that or those of the majority of the members of that union, branch or section (as the case may be) or does not possess the appropriate qualifications for such membership.
(3)A worker aggrieved by his exclusion or expulsion from any trade union, branch or section may apply to an industrial tribunal in accordance with industrial tribunal regulations for a declaration that he is entitled to be a member of that union, branch or section.
(4)Where any such declaration has been made and has not been implemented by the union, branch or section concerned within any period specified in the declaration or if no such period is specified within a reasonable period, the worker may apply to the High Court or, in Scotland, the Court of Session for an injunction, interdict or such other relief (including compensation) as the Court may think just and expedient in all the circumstances of the case.
(5)Nothing in this section or section 2(5) above shall prejudice or in any way reduce the common law rights of a person who has applied to join, but not been given membership of, or who claims to be and to remain a member of, or who has been expelled from, a trade union.
