On reviewing these items, the Policy Council shall then choose whether or not to recognize the Chapter. If the Policy Council does not recognize the proposed Chapter it shall inform the petitioners in writing of its decision and the reasons for the decision. The petitioners have the option to revise and resubmit their petition.

Section 1.8. Annual Review. In addition to maintaining its membership, each Chapter shall submit an annual report to the Policy Council through the Vice President – Chapters & SIGs by March 31st of each year.

SIGs shall be listed on the Society web site, and Society members shall be given the opportunity to indicate their association with a SIG using the Society website.
