Key legal question
Whether the cantonal court was entitled not to enter on the recusal request against judges and the clerk who had participated in the earlier IV judgment.
Extracted holding
Yes. Prior participation in an earlier decision on the same or related facts does not by itself create bias; no concrete signs of predetermined views were shown.
Extracted reasoning
A recusal request based only on an earlier negative judgment is inadmissible. Multiple judicial involvement is compatible with independence if the later outcome remains open; the claimant alleged no additional exclusion grounds.
