As Kuff explains it that’s kind of what it seems like, Point of disorder.
You can see the amended rule here. This is potentially a big deal, because Democrats have indeed been very adept at using points of order, known colloquially and amusingly as POOs, to stymie, delay, and sometimes kill outright bills they don’t like. Not just Democrats, of course, as anyone familiar with the oeuvres of Robert Talton and Arlene Wohlgemuth can attest, but it’s certainly been the main arrow in their quiver these past few sessions. Limiting their ability to wield this weapon will limit their ability to influence the outcomes. Having said that, I do have some sympathy for what Phil King says. There’s not really a principle behind POOs, and as they say about holding in the NFL, you could probably find such errors on every bill if you wanted to. It’s a matter of how much sway the minority is allowed, and how much authority the majority thinks it ought to have to enact its agenda. How you feel about these things is almost certainly directly proportional to your feelings about the majority and minority parties in the legislative body in question.
The new rule takes away the power the minority party, or the minority on a bill, has in the House of slowing down or killing a bill. It’s changes the filibuster rules in the Texas House.
