Appointment of company directors requires a Director Identification Number, consent filing, and rotation plus vacancy procedures. Section 152 requires directors to be appointed by the company in general meeting unless otherwise provided; first directors are the memorandum subscribers if articles are silent. Appointment requires a Director Identification Number and a declaration of non-disqualification, and the appointed person must file consent with the Registrar within thirty days. For public companies, at least two-thirds of directors must be those liable to retirement by rotation; about one-third of such directors retire at each annual general meeting, with prescribed rules for selection, vacancy filling, adjournment, and deemed re-appointment.
