Questão jurídica principal
Whether the cantonal court violated impartiality rules by deciding the recusal request itself
Decisão extraída
The recusal request was abusive and could be rejected by the court itself; no appearance of bias was shown.
Fundamentação extraída
The appellate court's assessment of a proof request in appeal is not the same as the first-instance assessment, so refusing new evidence did not prejudge the complaint against the lower court.
