The Boston New Sanctuary Movement is a membership-based organization. Both individuals and organizations may affiliate, which is done by signing a pledge. Major decisions are made by majority vote at participatory meetings held about once a month. These meetings are open to members and non-members alike. Each member organization is expected to send a representative. In between meetings, decisions are made by majority vote of a Steering Committee composed of five to seven delegates from member organizations. Delegates serve on the Steering Committee for a limited time on a rotating basis.
