2003/2004 update:
My dean assured me (and I should be able to verify, upon receipt of the dossier) that my departmental personnel committe, department chair, and dean all submitted positive recommendations. He also said 4 members of the TPRC voted against and 2 in favor (I thought TPRCs were supposed to have 7 members, so I assume 1 abstention).
I called the person designated in the letter to make an appointment for the next morning at 10am.
Since the decision was positive, no information was provided on the second TPRC vote, so I don't know whether my rebuttal changed any opinions on the TPRC or whether the chancellor decided to override the TPRC.
In any case, I am very grateful and happy that all this has concluded favorably.
