Kernrechtsfrage
Whether the recusal request based on prior participation in an earlier case should be examined
Extrahierter Entscheid
Prior participation in an earlier proceeding is not a ground for recusal under Art. 34 para. 2 BGG.
Extrahierte Begründung
The provision invoked by the applicants expressly excludes earlier participation as a ground of disqualification, so the request was inadmissible.
