An Indiana Subpoena — Hearing (Criminal Case) is an official court proceeding used by the court to obtain evidence in a criminal case. The subpoena is issued by a judge and requires a witness to appear in court to provide testimony or to produce documents or records. There are two types of hearings that can be conducted through a subpoena: an evidentiary hearing, which is used to determine whether the evidence presented is admissible, and a sentencing hearing, which is used to determine the punishment for a criminal conviction. Both types of hearings are generally conducted in open court and are presided over by a judge.
