ACBL operates under a set of bylaws established by the ACBL Board of Directors and the ACBL Board of Governors and ratified by the ACBL membership. The Board of Directors or the Board of Governors at any regular or special meeting of either body may amend the Bylaws. (The Board proposing the amendment is hereinafter referred to as the initiating body; the Board reviewing the proposed amendment is hereinafter referred to as the secondary body.)

The proposed amendment must be approved by a 2/3 vote of the initiating body. It must then be published in The Bridge Bulletin at least 30 days prior to the second reading by the initiating body. If approved upon a second reading by the initiating body, the proposed amendment is then referred to the secondary body. If approved by a majority vote of the secondary body, the proposed amendment is then submitted to the membership at a regular or special meeting. Upon approval by the membership the amendment is adopted.

The Bylaws may also be amended by the membership by providing a petition as outlined in Article X of the Bylaws. The petition is submitted to the Board of Governors and the Board of Directors for review and recommendation. The proposed amendment and recommendations are to be published in the Bridge Bulletin and then included on the agenda for the next Annual membership meeting. If approved by 2/3 of the members present and voting, the amendment is adopted.

NOTE: Please refer to the ACBL Bylaws, Article X, for a more detailed explanation of how the Bylaws may be amended.
