Credibility of Witnesses is a legal term used to refer to the trustworthiness of a witness's testimony in a court of law. The credibility of a witness is evaluated by the judge and jury, who must decide whether the witness is reliable and believable. Witnesses may be cross-examined by opposing counsel in order to establish their credibility. The two main types of Credibility of Witnesses are direct and circumstantial. Direct credibility is based on the witness’s actual testimony, such as their statements about what they saw or heard. Circumstantial credibility is based on the witness’s behavior, such as their level of confidence or their ability to recall facts. Other factors that can be used to determine the credibility of a witness include their behavior in court, their past criminal records, any potential bias they may have, and their relationship to the other parties involved in the trial. The credibility of a witness can be weakened if they are found to be untruthful, or if there is evidence that contradicts their testimony.
