New Mexico Statutes Chapter 53. Corporations § 53-8-20. Quorum of directors

A. A majority of the number of directors fixed by the bylaws, or in the absence of a bylaw fixing the number of directors, then of the number stated in the articles of incorporation, shall constitute a quorum for the transaction of business, unless otherwise provided in the articles of incorporation or the bylaws; but in no event shall a quorum consist of less than one-third of the number of directors so fixed or stated. 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 Nonprofit Corporation Act, the articles of incorporation or the bylaws.

B. 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.
