(a) A majority of the members shall constitute a quorum at a properly convened meeting of the Board. Any action of the Board shall require the concurring votes of at least a majority of those present and voting. The Board shall establish rules concerning timely notice of meetings.

(b) The Board may take action upon the concurring votes of a majority of members by mail, telephone, telegraph, or other means of electronic communication when, in the opinion of the chairperson of the Board, such action must be taken before a meeting can be called. Action taken by this emergency procedure is valid only if all members are notified and provided the opportunity to vote and any telephone vote is confirmed promptly in writing. Any action so taken shall have the same force and effect as though such action had been taken at a properly convened meeting of the Board.
