Hi everybody,
I am desperately looking for someone with experience in PhD examination, corrections, and appeal.
My story is as follows in short:
1. I passed my PhD viva with major corrections. was given a year to do them
2. Despite many personal circumestances, I managed to do them within time
3. After long time (over 3 months), the examiner decided to fail me as the work was not up to PhD level; however, in his explanation, he claimed that some parts of the work are not as they supposed to be (in specific) an online system I presented as a testing bed for some models I proposed)
4. The problem is, the same system was part of the work I presented before the viva and it was passed without any comments on it or any corrections to be made on it. meaning, is his rationale for failing me, he added new corrections that were never asked to done.
5. I applied for an appeal and it was accepted by the university. he was asked to resolve it informally by the appeal office but he refused.
6. I got my appeal hearing this Thursday and I am freaked out.

any advice is appreciated but my main question is: are internal examiners allowed to add more corrections after the official viva report?
