can you subpoena a judge to testify
Testifying in Court: It's an Order! When a lawyer asks you to testify in a criminal trial, you can agree to go voluntarily. In this case, you might not get an order by a judge to testify. These orders are called a  summons to appear or  subpoena . If you don't want to testify, or if a lawyer wants to make sure you show up, you could receive a subpoena. A subpoena is a document in which a judge orders you to testify. You will receive it in the mail, or a police officer or bailiff will deliver it to you personally. A subpoena contains important information including the date, time and place you need to testify.
