Impeachment of a Witness
The Impeachment of a witness - is the legal process used to challenge the credibility or truthfulness of their testimony. Attorneys use this tactic during cross-examination to show the jury that the witness cannot be trusted.
The primary methods used to impeach a witness include:
Prior Inconsistent Statements: Pointing out that the witness previously made an oral, written, or recorded statement that contradicts what they just said under oath.
Bias or Motive: Showing that the witness has a personal, financial, or emotional interest in the outcome of the case (e.g., a family relationship or a pending lawsuit).
Character for Truthfulness: Introducing evidence or asking about specific prior acts—such as a past felony conviction involving dishonesty—to suggest they are not a reliable person.
Contradiction: Presenting physical evidence, records, or the testimony of other witnesses that directly refutes a specific detail the witness claimed.
Impaired Capacity: Highlighting that the witness had poor perception or memory due to factors like distance, lighting, or being under the influence at the time of the event.
In federal and most state courts (such as the Federal Rules of Evidence), any party—including the one who originally called the witness to the stand—is allowed to attack that witness's credibility.
