The articles of association usually provide for the election of a chairman of the board.
They empower the directors to appoint one of their own number as chairman and to determine the period for which he is to hold office. If no chairman is elected, or the elected chairman is not present within five minutes of the time fixed for the meeting or is unwilling to preside, those directors in attendance may usually elect one of their number as chairman of the meeting.
The chairman will usually have a second or casting vote in the case of equality of votes. Unless the articles confer such a vote upon him, however, a chairman has no casting vote merely by virtue of his office.
Since the chairman's position is of great importance, it is vital that his election is clearly in accordance with any special procedure laid down by the articles and that it is unambiguously minuted; this is especially important to avoid disputes as to his period in office. Usually there is no special procedure for resignation. As for removal, articles usually empower the board to remove the chairman from office at any time. Proper and clear minutes are important in order to avoid disputes.
