Kernrechtsfrage
Whether the challenge to the diploma failure was admissible as a subsidiary constitutional complaint despite the prohibition of ordinary public-law appeal against exam results.
Extrahierter Entscheid
The matter had to be treated as a subsidiary constitutional complaint because ordinary public-law appeal was unavailable for examination results.
Extrahierte Begründung
Art. 83 lit. t BGG excludes the ordinary appeal against examination and other aptitude assessments; therefore the filing could only proceed under Art. 113 ff. BGG.
