Impeachment of Witnesses Because of Inconsistent Statements or Felony Conviction is a legal procedure used to challenge the credibility of a witness in a trial. The impeachment process is used to show that the witness has made prior inconsistent statements, or has been convicted of a felony, and thus cannot be trusted to testify truthfully. The two main types of impeachment of witnesses are due to inconsistent statements and felony conviction. In the case of impeachment due to inconsistent statements, the impeaching party must show that the witness has made statements that are materially different from one another. This can be done by referencing other testimony given by the witness, or by comparing written or recorded statements made by the witness. In the case of impeachment due to felony conviction, the impeaching party must prove that the witness has been convicted of a felony. The impeaching party must present evidence of the conviction such as court documents or official records. Impeachment of witnesses is a powerful tool that can be used by both defense and prosecution to challenge the credibility of a witness. It can also be used to cast doubt on the witness’s testimony and to present alternate versions of events.
