SEDEVACANTISTS
The reason you do not hear about Sedevacantists being excommunicated rests in the fact that the penalty of schism is incurred automaticly in canon law. For a Catholic to incur a latae sententiae pentalty all the conditions in canon 1323 must be met first. The concept of latae sententiae has no parallel in modern criminal law in most countries; but in a nutshell, a person who incurs a latae sententiae penalty does so ipso facto, without any judge or ecclesiastical authority imposing it on him.
In the 1983 Code of Canon Law (CIC) eight other sins carry the penalty of automatic excommunication: apostasy, heresy, schism (CIC 1364:1), violating the sacred species (CIC 1367), physically attacking the pope (CIC 1370:1), sacramentally absolving an accomplice in a sexual sin (CIC 1378:1), consecrating a bishop without authorization (CIC 1382), and directly violating the seal of confession (1388:1). - Apart from abortion, are there other sins that incur automatic excommunication?
From a Catholic perspective this is a logical conclusion when dealing with sedevacantists. How can one be in full communion with the Universal Catholic Church, if you refuse to acknowledge the pope, the Magisterium of the Church and the leaders of the Catholic Church and yet remain in full communion with the entire Catholic Church.
