This section applies where the rights attached to any class of shares in a company are varied under section 630 (variation of class rights: companies having a share capital).
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 shareholders 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 holders of a class of shares include references to their abrogation.
