Key legal question
Whether the federal appeal was admissible despite Art. 83 lit. t BGG
Extracted holding
The ordinary public-law appeal was unavailable against the practical driving test result, but the filing could be treated as a subsidiary constitutional complaint insofar as substantiated constitutional violations were raised.
Extracted reasoning
A practical driving test is a skills examination excluded by Art. 83 lit. t BGG. Because no other appeal path was available, the submission could be examined as a constitutional complaint under Arts. 113 and 116 BGG, limited to properly argued constitutional claims.
