Questione giuridica chiave
Whether the challenge to the first exam result was time-barred despite missing appeal instructions.
Decisione estratta
The first result was no longer part of the dispute; the cantonal court rightly refused to enter into the late challenge.
Motivazione estratta
The lack of appeal instructions did not make the decision void. Once the repeat exam was announced, the candidate had to know that a valid decision on the first failure existed and should have acted sooner.
