Key legal question
Whether the constitutional complaint was admissible despite Art. 83 lit. t BGG excluding ordinary public-law appeal against exam results.
Extracted holding
The ordinary public-law appeal was excluded, but the subsidiary constitutional complaint was admissible because the overall failure result and the underlying grades were reviewable.
Extracted reasoning
Art. 83 lit. t BGG bars review of exam results as such. However, where the overall failure depends on individual marks, the candidate has a legally protected interest in challenging the result and its basis.
