Not exactly. The 2d CA was very involved and in fact delayed the removal of the tube and ordered a 5 doctor review of Terri's prognosis in 2001. On another occasion the 2d CA ruled against Greer in his denial of new evidence. And it was the chief judge, I believe that ordered a guardian ad litem to prepare a report, which as we know was not favorable to the Schindler's motions. So I believe that the CA was quite involved throught the past 4 years at least.
Several other diagnostic tools had been invented since that time and any court worthy of the name would have demanded the best in evidence.
