Kernrechtsfrage
Whether the appellate panel was improperly composed because of a judge's prior expert mandate for the municipality
Extrahierter Entscheid
The prior one-off expert report for the municipality did not create an appearance of bias in this case.
Extrahierte Begründung
The expert mandate concerned different legal questions, was limited to a single report, and was long past; no objective basis existed to fear predetermination.
