Kernrechtsfrage
Whether the recusal request against judges who had previously decided cases involving the appellant had to be examined.
Extrahierter Entscheid
The request was not considered; prior decisions against a party do not, by themselves, establish judicial bias.
Extrahierte Begründung
Previous participation in earlier proceedings is not enough to call judicial independence into question under Art. 34 para. 2 BGG, so no recusal procedure under Art. 37 BGG was necessary.
