You are wrong. The judge admitted that her testimony was VALID - but that he wasn't going to change his mind so the outcome would be the same so what he said was that her testimony did not matter. There is A DIFFERNCE.
The bottom line is this. Diane Meyer's testimony was in error when she claimed that Terri said this in 1982. Since Terri was quoted by Diane as using the present tense (twice) during their conversation, the conversation had to have taken place prior to 1976 before the plug was pulled (the judge mistakenly said before she died, equating the two acts, a logical mistake).
Judge Greer's decision was appealed based on his error. The judge addressed this issue in writing during the appeal, and stated that it did not affect the outcome. The statements had to have been made prior to 1976 when Terri was only 11 or 12.
