Questione giuridica chiave
Whether the court-appointed expert was biased because he was employed by the University of St. Gallen and thus allegedly by the opposing canton.
Decisione estratta
The appointment did not violate the constitutional guarantee of an impartial expert; the employment relationship did not create a disqualifying dependence on the canton.
Motivazione estratta
The court held that the statutory disqualification rule for employees is not absolute. It must be interpreted in light of its purpose and the constitutional standards on impartiality. The expert's employment obligations ran to the university and its institute, not to the canton in the dispute, and no objective circumstances created a justified appearance of bias.
