Key legal question
Whether the appeal in public law matters was admissible against the result of the control drive and the resulting licence withdrawal.
Extracted holding
The appeal in public law matters was inadmissible because a failed control drive is a fitness test within Art. 83 lit. t BGG; that issue could not be reviewed through the ordinary federal appeal route.
Extracted reasoning
The control drive is a Fähigkeitsprüfung. Under the exclusion clause, only a subsidiary constitutional complaint remained available. The withdrawal was formally based solely on the failed drive, so no separate medical review issue opened ordinary jurisdiction.
