The decision of a ward disciplinary council can be appealed to the stake president. The following list of variables serves as a general set of guidelines for when excommunication or lesser action may be warranted, beginning with those more likely to result in severe sanction:   Notices of excommunication may be made public, especially in cases of apostasy, where members could be misled. However, the specific reasons for individual excommunications are typically kept confidential and are seldom made public by church leadership. Those who are excommunicated lose their church membership and the right to partake of the sacrament. Such persons are usually allowed to attend church meetings but participation is limited: they cannot offer public prayers or preach sermons and cannot enter temples. Excommunicated members are also barred from wearing or purchasing temple garments and from paying tithes. Excommunicated members may be re-baptized after a waiting period and sincere repentance, as judged by a series of interviews with church leaders. Some critics have charged that LDS Church leaders have used the threat of excommunication to silence or punish church members and researchers who disagree with established policy and doctrine, who study or discuss controversial subjects, or who may be involved in disputes with local, stake leaders or general authorities; see, e.g., Brian Evenson, a former BYU professor and writer whose fiction came under criticism from BYU officials and LDS Leadership. Another notable case of excommunication from the LDS Church was the "September Six," a group of intellectuals and professors, five of whom were excommunicated and the sixth disfellowshipped. However, church policy dictates that local leaders are responsible for excommunication, without influence from church headquarters. The church thus argues that this policy is evidence against any systematic persecution of scholars or dissenters. Data shows per-capita excommunication rates among the LDS Church have varied dramatically over the years, from a low of about 1 in 6,400 members in the early 1900s to one in 640 by the 1970s, an increase which has been speculatively attributed to "informal guidance from above" in enforcing the growing list of possible transgressions added to "Handbook" editions over time. Jehovah's Witnesses practice a form of excommunication, using the term "disfellowshipping", in cases where a member is believed to have unrepentantly committed one or more of several documented "serious sins". The practice is based on their interpretation of 1 Corinthians 5:11-13 ("quit mixing in company with anyone called a brother that is a fornicator or greedy person or an idolater or a reviler or a drunkard or an extortioner, not even eating with such a man...remove the wicked man from your midst") and 2 John 10 ("never receive him in your home or say a greeting to him").
