Key legal question
Whether the judicial recusal request was timely under cantonal procedural law
Extracted holding
The request was untimely because the applicant waited until the evidence phase had ended, although he had known the alleged grounds earlier.
Extracted reasoning
A party must invoke recusal as soon as the ground becomes known and may not let the judge continue to act. The applicant, assisted by counsel, tolerated the proceedings to continue and only filed the request after the final memorials.
