Section 4. Credentials of the delegates and alternates shall be sent to the Association ten (10) days prior to the date of the annual convention. No delegate or alternate shall be seated in the convention without credentials having been filed with the Association, unless he or she is seated by a majority vote of the recognized delegates of the convention. In the event a delegate cannot attend the Convention, an alternate from his or her city may be registered as a delegate, if approved by the Credentials Committee. The Credentials Committee shall make a determination arising from disputes in total membership in relation to the number of delegates allowed for each department. Such determination shall be subject to appeal to the Board and convention floor, respectively. To cast his or her vote, a delegate, or alternate, must be present in person and have his or her proper credentials. There shall be no voting by proxy.
