A qualifying person (P) may make a complaint to an employment tribunal that a term is void, or that a rule is unenforceable, as a result of section 145.

If the tribunal finds that the complaint is well-founded, it must make an order declaring that the term is void or the rule is unenforceable.
An order under this section may include provision in respect of a period before the making of the order.
