What is a subpoena ?

There are three kinds of Subpoena. A Subpoena to Testify requires a person to come to the Court to testify as a witness. A Subpoena for Records requires either documents or papers or writings, etc. to be brought to the Court. A Information Subpoena requires that information be provided to the person requesting it. If not obeyed, the court can order the person to appear and hold the person n contempt of court if they disobey. Sanctions such as fines can also be ordered. Avoiding service of a subpoena is hard to prove and may not be punishable at all.
