Kernrechtsfrage
Whether Christoph Bandli had to recuse himself because he had participated in earlier decisions on the same legal question.
Extrahierter Entscheid
No. Prior participation in earlier cases involving the same legal issue, without involvement in the same concrete case or additional objective indications of bias, does not create an appearance of partiality.
Extrahierte Begründung
Art. 34(2) BGG excludes recusal based solely on prior participation. The earlier judgments clarified legal questions through interpretation; that does not mean the judge is closed to new facts or arguments in later, different cases.
