ARTICLE 6. Resolutions A. Resolutions committing the Association to a stand on a public issue require a two-thirds majority of those voting at the biennial business meeting or by e-mail ballot.

B. Resolutions directly related to genocide or other mass atrocities, including early warning signs thereof, may be proposed by any member in good standing.

Proposed resolutions shall first be submitted to the Resolutions Committee appointed by the President and the Executive Board for review of their linguistic clarity and historical and factual accuracy. The standard of review shall be that of an article for the IAGS journal. The Resolutions Committee will recommend to the Executive Board and Advisory Boardwhether the Resolution should be forwarded to the IAGS membership for a vote.

D. After consulting with the Advisory Board, the Executive Board shall decide whether or not the proposed resolution will be submitted to the IAGS membership for a vote within two weeks of submission by the Resolutions Committee. Resolutions must be circulated by the Executive Board to the IAGS membership at least thirty days before the close of voting by IAGS members. E-mail voting shall begin as soon as the resolution is submitted to the membership by the Executive Board and close at the end of thirty days of voting. Votes will be submitted and counted by the Secretary/Treasurer of the IAGS, and after verification by the Executive Board, results of the voting will be announced to the members of the IAGS.
