A hostile witness (also called an adverse witness) is a witness who is openly adverse to the party that called the witness. If the court finds that a witness is hostile, it may permit the party to ask the witness leading questions on direct examination, which is not normally allowed.
Millie Miller is called to testify by her ex-husband’s defense attorney as to her ex-husband’s whereabouts on the night of June 16th. Miller immediately begins swearing at her ex-husband in the courtroom, raising her voice and saying that her ex-husband, who has been accused of murder, should get the death penalty. The ex-husband’s lawyer asks the court to declare Miller a hostile witness, and the court agrees, allowing the lawyer to ask Miller leading questions on direct examination.
