The Fifth Amendment Privilege of Witness Other Than the Defendant is a legal right to remain silent when called to testify in a criminal case. This privilege is intended to protect witnesses from self-incrimination and to promote truthful testimony in criminal proceedings. It allows witnesses to decline to answer any questions that would tend to incriminate them in any matter that could lead to criminal prosecution. There are two types of Fifth Amendment Privilege of Witness Other Than the Defendant: the "transactional immunity" and the "use and derivative use" immunities. Transactional immunity grants a witness complete immunity from prosecution for any testimony they give during a criminal trial. The use and derivative use immunities protect a witness from having their testimony used against them in any other criminal proceeding, even if the witness voluntarily provided the information.
