I don't have access to the court documents yet, so I can't give a full analysis at this time, but a coalition of plaintiffs has filed a new school finance challenge in Texas. Details here.
A couple of initial points based on the linked story. First, this is not a part of the longstanding Edgewood v. Kirby litigation, the last iteration of which was decided by the Texas Supreme Court in 2005. It is a new case. Second, it is difficult to be sure from the summary, but the claims appear to be based more on "equity" theories than on "adequacy" theories, though there is a nod to adequacy at the end of the story.
Any readers with more specific information are invited to comment.
