This is your Bishop :
What, you think it is impossible that a Bishop would propagate heresy? If that were the case, then Nestorius would not have held his infamous Christmas sermon many centuries past.
I'm not sure the pope can be tried on the basis of canon law. I would like to see the details of this proposed tribunal.
The Pope cannot be tried on the basis of human laws, since he is above these, but before he loses the papal office, he must nevertheless have spurned public admonitions directed to him by the ecclesiastical hierarchy. This is all basic. God hates disorder, and the system of the Sedevacantists is just that; disorder. The Church, being a public society, simply does not work that way. Added to that, the whole Episcopate cannot be unaware of a Pope losing his office, due to the theological principle of universal recognition, since the God-given quality of indefectibility excludes the possibility of the Church submitting itself to a principle of schism, which a false pope essentially is.
The answer to the question is that it has happened before and there is nothing hypothetical to that fact.
What happened before? That the universal Church has been bereft of bishops in possession of episcopal seats? No, that has never happened before, it is not happening today, and it will never happen in the future. And I was not saying that this was hypothetically possible; I was referring to appointment of bishops to dioceses, with the explicit jurisdiction to do so, during interregna, and not to your mutilated concept of ecclesiastical jurisdiction.
Read what I have written, and then read what you have answered. That is troll behaviour, and if you insist on continuing it, then do not bother expecting more responses from me. I am not foolish enough to waste my time with such games.
