"These principles are more than just recommendations. As of July 1, all new and renewing SIA members will be required, as a condition of membership, to affirm that they will abide by the principles. If a member who has made that affirmation is determined by the SIA Executive Committee to have committed a material violation of one or more of the principles, that member may be subject to punitive action, ranging from a written warning to suspension of membership to expulsion from the association. All decisions by the Executive Committee concerning possible violations and SIA’s response will be final," says SIA.
