Quorum of directors.
A majority of the number of directors as fixed pursuant to Section 53-11-36 NMSA
1978 shall constitute a quorum for the transaction of business unless a greater number
is required by the articles of incorporation or the bylaws. A quorum, once attained at a
meeting, shall be deemed to continue until adjournment notwithstanding the voluntary
withdrawal of enough directors to leave less than a quorum. The act of the majority of
the directors present at a meeting at which a quorum is present shall be the act of the
board of directors, unless the act of a greater number is required by the articles of
incorporation or the bylaws.
