Key legal question
Whether the cantonal chamber could refuse to enter into the recusal request as untimely
Extracted holding
Even if the request had been timely, the challenge would fail because the alleged procedural defect would not amount to a legally relevant ground for recusal.
Extracted reasoning
An isolated procedural error in the conduct of the investigation does not by itself establish bias. Recusal requires particularly serious and repeated mistakes showing lack of distance or neutrality, which were not present here.
