Individual director appointments required; multiple appointments by one resolution invalid unless unanimously agreed by the meeting. Section 263 mandates individual voting for director appointments in public companies and their private subsidiaries; appointing two or more persons by a single resolution is prohibited unless the meeting first consents without any vote against. Resolutions contravening that rule are void, and if such a resolution is passed the statutory automatic re appointment of the director retiring by rotation will not apply. Motions to approve or to nominate a person are treated as motions for appointment.
