My only response is to shake my head and mutter "only in Texas...." After all, aren't they the ones who are intentionally and militarily refusing to abide by a SCOTUS ruling....
For what it's worth, the House itself gets to decide what it's rules are and can enforce or not enforce the quorum rules affirmatively or negatively. I would suggest that enforcement of the House's quorum rules is reserved to the members of the House. In other words, if a House member doesn't object, then the House has made a defacto determination that a quorum exists, or that it doesn't apply at the time. "After the fact" determinations are inapplicable, inappropriate, and inconsistent with a Federal form of government. Individual states have no power to overturn what the legislative body has done. Constitutional determinations can only be made on the basis of the text of the Constitution, not the internal (or inferno) rules of a specific body....
