Key legal question
Whether the cantonal court arbitrarily refused to annul the first-instance judgment because the presiding judge changed after a conciliation attempt.
Extracted holding
No arbitrariness was shown, because the second president conducted the proceedings anew and participated in all required operations.
Extracted reasoning
Under the cantonal rules, judges who deliberate and judge must have attended the earlier proceedings. The record showed that the new president led the whole hearing, including a new conciliation attempt, so the case was effectively restarted ab initio.
