Impeachment Witness Credibility Challenge Information
Methods of impeachment: prior inconsistent statements (the witness previously made: a statement that contradicts the current testimony), bias or motive (the witness has: a reason to testify favorably for one side: financial interest, personal relationship, or deal with the prosecution), character for untruthfulness (the witness has: a reputation for dishonesty or has been convicted of a crime involving dishonesty), contradiction (other evidence contradicts: the witness's testimony), and sensory deficiency (the witness's ability to: perceive, remember, or communicate was impaired: poor eyesight, intoxication, or mental illness). Effect: impeachment undermines the witness's credibility (the factfinder may: disbelieve some or all of the testimony).
Florida Legal Definition
Witness impeachment in Florida is governed by the Florida Evidence Code (Florida Statutes §90.608-§90.610). Under §90.608: any party may attack the credibility of a witness. Under §90.609: a witness's character for truthfulness may be: attacked by reputation or opinion evidence. Under §90.610: a witness may be impeached by: a prior conviction (if the crime was punishable by death or imprisonment of more than 1 year, or involved dishonesty). Under §90.614: a witness may be impeached by: a prior inconsistent statement (the examiner must: disclose the contents to the witness and give the witness an opportunity to explain). Under Florida practice: the attorney must: lay the proper foundation for each method of impeachment.
How It's Used in Practice
Attorneys manage witness impeachment. For the impeaching party: prepare the impeachment materials before trial, lay the proper foundation (confronting the witness with: the prior inconsistent statement, the bias, or the conviction), present the impeachment evidence effectively, and argue the witness is not credible. For the party supporting the witness: rehabilitate the witness (explain the prior statement, denial of bias, and context for the conviction), present positive character evidence, and argue the impeachment evidence is: minor, irrelevant, or insufficient to undermine credibility. The attorney advises: impeachment is a critical trial skill; prepare impeachment materials carefully; lay the proper foundation; effective impeachment can: change the outcome of the case.
