Appointment of directors: board may appoint additional, alternate or nominee directors subject to tenure and qualification limits. The Board may, if authorised by the articles, appoint an additional director until the next annual general meeting; appoint an alternate director during a director's absence from India for not less than three months with restrictions on alternate directorships and independence qualifications; appoint nominee directors where nominated by law, agreement or government shareholding; and, in public companies, fill casual vacancies so appointed persons serve only for the remainder of the original director's term.
