§ 53-18-6 NMSA 1978

Whenever a section of the Business Corporation Act specifies the vote of the holders of a certain proportion of the shares, or of any class or series thereof, for the taking of any action by the shareholders of a corporation, the articles of incorporation may require a greater proportion. An amendment to the articles of incorporation which adds, changes or deletes a provision for a greater proportion must be adopted by the same vote as would be required to take action under the provision to be adopted or then in effect, whichever is greater.
