What is information that discredits a witness's testimony called?

• A. Jencks Act
• B. eDiscovery
• C. Valid defense
• D. Impeachment evidence

Answer: (D)

Impeachment evidence is information used to undermine a witness’s credibility by showing they are unreliable, biased, have a motive to lie, or have prior inconsistent statements or dishonesty. This type of evidence targets how believable the witness is, not directly proving what happened. That makes it the right label for discrediting testimony. For context, other terms refer to different ideas. The Jencks Act governs the production of a witness’s prior statements after they’ve testified, not the general concept of challenging credibility. eDiscovery deals with locating and producing electronically stored information in litigation. A valid defense is a broader trial strategy, not specifically about undermining a witness’s trustworthiness.
