Section 512B.12 - Amendments to laws1. A domestic society may amend its laws in accordance with the provisions of its laws by action of its supreme governing body at any regular or special meeting or, if its laws so provide, by referendum. A referendum may be held in accordance with the provisions of the society's laws by the vote of the voting members of the society, by the vote of delegates or representatives of voting members, or by the vote of local lodges. A society may provide for voting by mail. An amendment submitted for adoption by referendum shall not be adopted unless, within six months from the date of submission of the referendum, a majority of the members voting have signified their consent to the amendment by one of the methods specified in this subsection.2. An amendment to the laws of a domestic society shall not take effect unless approved by the commissioner.

An amendment shall be considered approved, unless the commissioner disapproves the amendment in writing, within thirty days after the filing of the amendment. The disapproval of the commissioner shall be in writing and mailed to the secretary or corresponding officer of the society at its principal office. If the commissioner disapproves an amendment, the reasons for disapproval shall be stated in the written notice.3. Within ninety days from the approval of an amendment by the commissioner, the amendment, or a synopsis of it, shall be furnished to all members of the society either by mail or by publication in full in the official publication of the society.
