Key legal question
Whether the public law appeal was admissible against the removal from the interpreter register following a failed proficiency test.
Extracted holding
No; the challenged decision directly resulted from an assessment of personal linguistic ability, which is excluded from the public law appeal under Art. 83 lit. t BGG.
Extracted reasoning
The exclusion applies to all decisions concerning the assessment of personal abilities, regardless of how the complaint is framed. The matter is only reviewable, if at all, through the subsidiary constitutional complaint.
