I believe the courts are pointless. Greer has the legal authority under the statute to remove the tube. Just go in and give her water and see if she can take it. Greer's order that no one can give her water is illegal on the face of it. The statute only allows Greer to remove "artificially" supplied food and water.
It might take an emergency order or better yet forget the courts and get the Governors office to take marshalls to tell whatever law enforcement is on site to stand down -- the courts do not direct law enforcement, the Governor does -- and let medical doctors try to hydrate her by mouth. Can't Jeb Bush do even this much to give Terri one last chance?
Deserves repeating!
