This section applies where the rights of any class of members of a company are varied under section 631 (variation of class rights: companies without a share capital).
Members amounting to not less than 15% of the members of the class in question (being persons who did not consent to or vote in favour of the resolution for the variation) may apply to the court to have the variation cancelled.
If such an application is made, the variation has no effect unless and until it is confirmed by the court.
Application to the court must be made within 21 days after the date on which the consent was given or the resolution was passed (as the case may be) and may be made on behalf of the members entitled to make the application by such one or more of their number as they may appoint in writing for the purpose.
References in this section to the variation of the rights of a class of members include references to their abrogation.
