Ah, so yet another NEW position: sedeimpoundinvirtueofcanon2264ist
Let's call it sedeimpoundism for short (since Father coined the term) ... or sedequarantinism. I'd leave out the reference to Canon 2264 (or any other Canon), since Popes are not subject to Canon Law.
Father Chazal now clarifies that they have no teaching authority, but still have valid but illicit jurisdiction.
I actually like this. It's not too different than my own spin on sedeprivationism, as I called it, where I believe that jurisdiction can be passed on through material popes and formally exercised by anyone he designates to have it without an impediment to do so.
I may just have been converted to sede-impoundism. [I have never been a PURE sedeprivationist but closer to this anyway.]
