At a general meeting of a public company a motion for the appointment of two or more persons as directors of the company by a single resolution must not be made unless a resolution that it should be so made has first been agreed to by the meeting without any vote being given against it.

A resolution moved in contravention of this section is void, whether or not its being so moved was objected to at the time.

But where a resolution so moved is passed, no provision for the automatic reappointment of retiring directors in default of another appointment applies.

For the purposes of this section a motion for approving a person's appointment, or for nominating a person for appointment, is treated as a motion for his appointment.

Nothing in this section applies to a resolution amending the company's articles.
