Permission for the attendance of non-members at one or more sessions may be given at the discretion of the clerk, if satisfied that their presence is likely to be of service to the Society. Such permission should be sought well in advance of Yearly Meeting and should be supported by one or more elders to whom the applicant is well known. Last-minute requests should not be made. Elders supporting applications should ensure that non-members receive suitable support and guidance to enable them to be of service and to benefit from attendance at Yearly Meeting. If called to speak in a Yearly Meeting session, non-members should be sensitive to the fact that they are not in membership and should make this known.
