Questione giuridica chiave
Whether the constitutional complaint was admissible against the lower exam decision and the cantonal appeal decision
Decisione estratta
The complaint was admissible only against the cantonal appellate decision; it was inadmissible insofar as it also targeted the underlying exam decision and sought more than cassation.
Motivazione estratta
The cantonal commission had final review powers, so the lower decision could not be separately attacked. The remedy was purely cassatory.
