No matter what its title, an order assigning a case (or here, a habeas corpus petition) to a particular judge is an all purpose assignment that requires a party to file a 170.6 motion within ten days of the assignment or of the party’s appearance, whichever is later if (a) the order instantly pinpoints the judge whom the parties can expect to try the case, and (b) the assigned judge is expected to process the case in its totality thereafter. Here, an order assigning a habeas corpus petition to a particular judge for “review and ruling” satisfied those conditions. Also, the People made their appearance in that proceeding not when they filed opposition to the petition, but on the earlier date when the assigned judge directed the People to file the opposition.
