Inviting the Accused to the Judicial Hearing
It is best for two elders to invite him orally. Their invitation should include the following information:
- Make clear that the meeting is a judicial hearing.
- Explain what his course of action is alleged to have been.
- State the time and place of the hearing and how the person can contact the chairman if the person is unable to meet at the scheduled time and location
The assigned elders should make every effort to arrange for a judicial hearing right away. Leaving the matter unresolved can harm the congregation and the accused. If the accused does not make himself available to receive an oral invitation despite repeated efforts by the judicial committee, then the judicial committee should send a written invitation. (Do not leave confidential information on an answering machine or voice mail or send by way of e-mail.) A written invitation signed by the judicial committee should include the same information as outlined above for an oral invitation. If possible, send the invitation in such away that the elders can verify that the addressee received it. If they are unsuccessful in their diligent efforts to invite him and they cannot confirm that he received the invitation, they should hold the matter in abeyance.
