What I'm saying is that I am personally aware of several cases from the late 1980s and early 1990s where no "investigation" was done before performing conditional ordinations.
Right,
I'm thinking that the old SSPX were more than happy to conditionally re-ordain novus ordo priests without conducting an investigation, "just in case". Now it seems that the present SSPX presumes that any novus ordo priest who wants to join them, is validly ordained, and they may investigate his ordination if it calls for.
