Questione giuridica chiave
Whether the bias challenge against the cantonal judges was timely and effective
Decisione estratta
The challenge was untimely because the alleged grounds were only raised before the Federal Supreme Court, although they were known during the cantonal rehearing.
Motivazione estratta
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.
