18 GCA § 17815: Quorum.

(a) Unless the articles of organization provide for a greater number, a majority of the total number of directors specified by the organic rules constitutes a quorum for a meeting of the directors.

(b) If a quorum of the board of directors is present at the beginning of a meeting, any action taken by the directors present is valid even if withdrawal of directors originally present results in the number of directors being fewer than the number required for a quorum.

(c) A director present at a meeting but objecting to notice under § 17814(b)(1) or (2) does not count toward a quorum.
