This will probably go to a higher court. Although, it is great that Texas courts are sticking up for the kids.
Not likely. If you had read the story, you would know that this was in US District Court and that the US Justice Dept has begun investigating the Plano ISD policies. It is not in the district's best interest to pursue this to US Circuit Court and higher just as US DoJ has begun to roto-root their system.
It's not a state court.
