Where I practice every one of those cases already has a court-appointed attorney for every parent and an ad litem attorney for the child(ren). This may be a way to help poorer counties get attorneys on the appointment wheels who are actually somewhat competent to be on that wheel. I've witnessed opening statements in a CPS trial where a parent's attorney couldn't remember his client's name, did not know he was actually emplolyed, and whose grasp of the facts of the case seemed to stop with the general understanding that children tend to have parents.
The changes for Sept. 1 seem simply be "Miranda for CPS," (which isn't a substantive change, just a notice/procedure change) and the requirement to report your name when calling in to CPS (which I think was correctly stated above as more to help keep CPS out of high-conflict, non-abuse/neglect custody matters). Which is to say that I don't see huge changes here.
Y'all need to remember that the crazies that run this state still see CPS as an enemy because of CPS playing it straight in the Younger case (case worker testifying that the child ID'd as a girl, tesifying that the child was afraid of the father). Even though Abbott turned around and tried to weaponize CPS against families who listen to their children and follow the advice of medical professionals, the whackjobs do not see CPS as an agency that needs funding. In 2021 the legislature made it slightly harder to remove children from their parents. That bill was a mixed bag, and part of it was getting rid of marijuana as an almost instant neglect finding, part was because the foster system is overloaded and the last thing people want to do is spend money on things that matter, but the train was driven by CPS getting put in the crosshairs by the Texas GOPs brain-dead base.
Phelan, I do believe, is trying to hold back the nutters from gutting CPS completely (unless you're kid is trans and you're acting appropriately).
