If the Decision Is to Disfellowship
27. The following information should be conveyed orally to the wrongdoer after informing him of the committee's decision:
• Outline the steps necessary for future reinstatement.
• Inform the wrongdoer that he may appeal in writing within seven days if he feels a serious error in judgment has occurred. (od pp. 153-154) He should address his letter of appeal to the judicial committee.
29. If the unrepentant wrongdoer did not attend the judicial hearing, the judicial committee should make reasonable efforts to inform him ORALLY of their decision, his option to appeal, and so forth. The elders should not leave a message of a confidential nature on a telephone answering machine or by means of voice mail or by way of e-mail. If he does not cooperate with the efforts to inform him, the judicial committee should contact the branch office.
Obviously, it is not recommended to send any kind of written announcments about disfellowshipping.
