Well, then the family's lawyers are incompetent.
How come you can see the injustice of the order of no food or water by mouth,and I can see it, and everyone except a few deatocrats but all the appellate judged can't see it,and say, well this is beyond the pail, her lawyers need to go back to school,but we will use "an equitable remedy"(real legal principle) and let her have a shot at swallowing a few sips of water,on the off chance that she could.
The more the judges at State and federal level especially SCOTUS refuse to grant that remedy,the more you really have to believe that they have an agenda:ie.Warning shot to those who want to tell the robes what to do.
