As is stated in another thread on an article by a doctor (William Anderson) in the Weekly Standard titled "Terri's Last Chance" there is no medical, legal or moral reason to not attempt a trial of natural drinking. He argues all the outcomes of such a trial, even if it results in a quicker death, are better than refusing to allow her to attempt to take food and water on her own. Only Greer's order stops this and such an order is not within the power of a court to make.
Jeb and George Bush should blast Judge Greer out of the water on this illegal order and immediately give her water by mouth. Who is going to stop them? All the law enforcement people are under the governor's jurisdiction. Greer is only getting away with this order by default because there has been so much focus on the feeding tube and I don't think this issue has even been pressed. We don't know if Terri could accept enough nutrition to stay alive but every human being has the right to try to take a drink of water! If it works, this could allow time to dismiss Greer for violating her human rights by his order and overturn the guardian decision.

It's in there. If I wasn't so exhausted over this, I'd point you to the details. Here are links to some posts where I quote and discuss clauses ...
