If you were subpoenaed to appear on the trial date (or any other court date), then you must appear and be present on the date and time reflected on the subpoena. If you received a “stand-by” notice, then you are on telephone alert but must appear if called by the District Attorney’s Office to do so. Many victims and witnesses receive a “stand-by” notice, which is explained above. If you are a victim you have the right to be present, whether you will be needed to testify or not. Moreover, most criminal court hearings are open to the public.
