If this is indeed the case, then it is one more reason the SSPX cannot be considered "schismatic", even by Newchurch standards. Just as you don't give schismatics faculties, neither do you appoint their bishops to the Roman Rota.
If Rome proclaims latae sententiae excommunication of Fellay et al in July, I would assume he will lose this job. The faculties are probably also in jeopardy, at least for the bishops involved (as I understand it, LS excommunication wouldn't percolate down to SSPX priests, in that they aren't the ones doing the consecrating, nor are they receiving it aside from the priests chosen to be consecrated).
