This appears to be the reasoning: The first and second attempts were invalidated because both were inadmissible under the examination regulations (strictly speaking, the student should have failed on the first attempt). Therefore, a new exam date was scheduled, on which the student then failed for the same reason, he should have failed on the first attempt (the exam regulations do not provide for exceptions due to nervousness, but rather stipulate that the examinee fails in such cases because his performance is insufficient to pass).

So only the third attempt was counted, which meant the student did not receive his diploma, since he would have had to pass that oral exam to do so - which, unfortunately, he did not after his second attempt was striken from the record.

My friend had simply tried to appeal to human leniency, which is strictly speaking not permitted under official rules. It’s quite possible that the first attempt wasn’t even officially recorded, since the student should have already failed. Unfortunately, I don’t know what exactly was recorded for the first attempt.

Apparently, however, the judge or the responsible administrative official at the Ministry of Education had at least some sympathy, since they had the entire exam retaken. But it’s also quite possible that this is the standard procedure when inconsistencies arise regarding the exam regulations. Administratively, it’s probably way easier than initiating an detailed “investigation” of the case.

But yeah, all in all: pretty strange.

Edit: I think it is certainly possible to reschedule an exam, but I assume that a doctor’s note must be submitted to prove that the examinee is unable to take the exam for health reasons.

The student might have been able to get such a note, but since this seems to be an ongoing problem, it would probably have been nothing more than a temporary reprieve.
