These folks have asserted that the pastor and the bishop have no right to govern the parish. 80% of the parish is still there. They stopped funding it. By their disregard of Canon 212 ß1, they've made the rest of your citations - most of which are irrelevant - moot.

A tree which is bad at the root cannot bear fruit under Canon Law.

Now, they might be able to get someone like Thomas Doyle, who may be incompetent as a canon lawyer but surely does love the publicity, to try to make a case out of this, but they're going to come off like an angry bunch who make demands, and no one in Rome wants to foment that sort of thing, especially in the litigious USA.

They’ve already lost by their actions.
