An individual who is or has been a member of a trade union has the right not to be unjustifiably disciplined by the union.
For this purpose an individual is "disciplined" by a trade union if a determination is made, or purportedly made, under the rules of the union or by an official of the union or a number of persons including an official that—
and whether an individual is "unjustifiably disciplined" shall be determined in accordance with section 65.
Where a determination made in infringement of an individual's right under this section requires the payment of a sum or the performance of an obligation, no person is entitled in any proceedings to rely on that determination for the purpose of recovering the sum or enforcing the obligation.
Subject to that, the remedies for infringement of the right conferred by this section are as provided by sections 66 and 67, and not otherwise.
The right not to be unjustifiably disciplined is in addition to (and not in substitution for) any right which exists apart from this section; and, subject to section 66(4), nothing in this section or sections 65 to 67 affects any remedy for infringement of any such right.
