Here is an interesting bit from the DICI site of the SSPX:
GENERAL HOUSE PRESS RELEASE
Filed under From Tradition, News
The Superior General, Bishop Bernard Fellay, has learnt by the press of Bishop Richard Williamson’s decision, just ten days before his trial, to dismiss the lawyer charged with his defense, in favor of a lawyer who is openly affiliated to the so-called neo-Nazi movement in Germany, and to other such groups.
Bishop Fellay has given Bishop Williamson a formal order to go back on this decision and to not allow himself to become an instrument of political theses that are completely foreign to his mission as a Catholic bishop serving the Society of Saint Pius X.
Disobedience to this order would result in Bishop Williamson being expelled from the Society of Saint Pius X.
