Impeachment of Defendant's Character Witness is a legal process wherein the prosecutor or defense attorney questions the credibility of a witness who has testified in favor of the defendant. The purpose of impeachment is to cast doubt on the reliability and trustworthiness of the witness's testimony. There are three types of Impeachment of Defendant's Character Witness: 1. Direct Impeachment: This is when an attorney challenges the facts of the witness's testimony. 2. Impeachment by Prior Inconsistent Statement: This is when an attorney uses a prior statement of the witness to contradict the witness's current testimony. 3. Impeachment by Prior Inconsistent Conduct: This is when an attorney challenges the witness's credibility based on the witness's past conduct.
