I know the SSPX grants "Declarations of Nullity" (or rather, opinions regarding the nullity of marriages using pre-Vatican II norms), but do any other traditionalist bishops do this? "Lack of form" would be pretty much a no-brainer, but "annulments" for any other reason --- is this a "thing" in traditional Catholicism? And what does a traditional Catholic do, if they are divorced and want to be free to remarry?
Does "supplied jurisdiction" extend to being able to declare lack of form, or to find putatively valid marriages null and void?
