The shareholders may always amend the bylaws. The board of directors may amend the bylaws unless the articles of incorporation state otherwise, or unless the shareholders provide that the bylaws may not be amended by the board.
The articles of incorporation may allow a bylaw that requires a greater quorum or voting requirement for shareholders, but such a requirement may not be adopted, amended, or repealed by the board of directors. A bylaw that fixes a greater quorum or voting requirement for the board of directors, and that was adopted by the shareholders, may be amended or repealed only by the shareholders. If it was adopted by the board, it may be amended or repealed only by the board.
