Question juridique clé
Whether the bias challenge against the cantonal judges was timely and effective
Solution extraite
The challenge was untimely because the alleged grounds were only raised before the Federal Supreme Court, although they were known during the cantonal rehearing.
Motifs extraits
A party must raise a recusal ground immediately upon learning it; by proceeding without interruption, the right is forfeited. The appellant had already made earlier, different recusal requests and deliberately did not object when the concrete remarks were made.
