3 Cards On This Topic:

If judge known 10 days before trial, challenge must be made 5 days before trial. If not, must be made when case assigned for trial.

If no reasonable certainty as to trial judge's identity, general CCP 170.6 rule, that a challenge may be made any time before trial, applies.

If case assigned to department which has normally assigned judge, then 10-day/5-day rule applies to that judge.
