They were disqualified because of what came out of their mouths.
What came out of their mouth was that Terri could be rehabilitated and that she was not pvs. They were disqualified because Judge Greer decided that was not the diagnosis he wanted. And you were the one who in your previous post said the court did not give their testimony consideration,- your quote was"Yeah, well, the court gave their testimony the consideration it deserved." Which implies the court did not value them as having valid credential to to even listen to their testimony on Terri's state of mind. Which is why I say the entire court trial was a sham.
