What all the other judges have had before them are the results of that first trial presided over by Judge Greer. So, they weren't 'new trials' because the only evidence they ever had before them was the evidence gathered by that first trial. Following trials were to decide if the first trial was fair.
I have come to the conclusion that Terri Schiavo will tragically die of malnutrition and dehydration very soon. On the say so of a husband who never mentioned she wanted it this way until seven years after the accident and two years into a relationship with a woman with whom he had a child (at that time, now they have two). If she were my daughter I would also be moving heaven and hell to have her not starved to death.
No doubt.
