Impeachment of Witness — Prior Inconsistent Statement for Credibility Only is a legal procedure in which a witness' credibility is challenged by introducing prior inconsistent statements made by the witness. This type of impeachment of witnesses can only be used for the purpose of assessing the witness' credibility, and not for the purpose of establishing the truth of the matter in dispute. There are three types of impeachment of witness — prior inconsistent statement for credibility only: 1. Writing Impeachment: This involves introducing a written document that contains a prior inconsistent statement made by the witness. 2. Oral Impeachment: This involves introducing a prior statement made by the witness to another person or in a prior proceeding. 3. Cross-Examination Impeachment: This involves introducing a prior inconsistent statement made by the witness in answer to a question during cross-examination.
