In State v. Michielli, 132 Wn.2d 229, 937 P.2d 587 (1997), the prosecutor obtained amendment of the information just days before trial was set to begin, even though the prosecutor knew months before that there was evidence that supported the additional charges. The Court held there that the " defendant was prejudiced in that he was forced to waive his speedy trial right and ask for a continuance to prepare for the surprise charges brought three business days before the scheduled trial." Michielli, 132 Wn.2d at 244.
