Legal Definitions - failure to testify

Failure to testify refers to a situation in a legal proceeding where an individual, such as a defendant, a witness, or a party to a civil case, chooses not to provide evidence or answer questions under oath.

In criminal cases, a defendant's decision not to testify is a fundamental right protected by the Fifth Amendment of the U.S. Constitution, which guards against self-incrimination. This means a defendant cannot be compelled to speak, and their silence cannot be used as evidence of guilt by the prosecution or considered by a jury as an admission of wrongdoing. In other legal contexts, such as civil cases or for non-defendant witnesses, the implications of a failure to testify can vary depending on the specific legal rules and circumstances.

• Example 1 (Criminal Defendant):

  During a trial for alleged assault, the defendant's lawyer advises them not to take the witness stand. The defendant agrees and remains silent throughout the presentation of evidence.

  How this illustrates the term: This is a clear instance of "failure to testify." The defendant, despite being present and having the opportunity, chose not to offer their own account or respond to the accusations. The judge would instruct the jury that they cannot interpret this silence as an admission of guilt.

• Example 2 (Civil Party):

  In a civil lawsuit concerning a disputed property boundary, one of the property owners involved in the dispute decides not to present their own testimony, instead relying solely on the testimony of surveyors and property deeds.

  How this illustrates the term: Here, a party to a civil dispute has exercised their right not to testify. While not protected by the same constitutional safeguards as a criminal defendant's silence, their decision not to offer personal testimony still constitutes a "failure to testify." The court will evaluate the case based on the evidence that *was* presented.

• Example 3 (Witness Invoking Rights):

  A witness is subpoenaed to testify before a grand jury investigating financial fraud. When asked a question that could potentially implicate them in illegal activities, the witness invokes their Fifth Amendment right against self-incrimination and refuses to answer.

  How this illustrates the term: This is another form of "failure to testify." The witness is present but legally refuses to provide testimony on specific questions, exercising a constitutional right to avoid self-incrimination.
