A prior inconsistent statement is an earlier statement that conflicts with a witness’s current testimony and may be used to impeach credibility.
Why a prior inconsistent statement matters
A prior inconsistent statement matters because credibility can be central at trial. If a witness tells one version before trial and another version in court, the difference may help the factfinder evaluate reliability, memory, bias, or truthfulness.
Some prior inconsistent statements may also be admitted for their truth under specific evidence rules, but many are used mainly for impeachment.
Where a prior inconsistent statement appears
Prior inconsistent statements appear in cross-examination, impeachment, depositions, police reports, affidavits, prior testimony, recorded interviews, and trial objections.
Practical example
A witness testifies that a light was green, but in a deposition the same witness said they did not see the light. The deposition answer may be used to challenge the witness’s testimony.
How a prior inconsistent statement differs from nearby terms
A prior inconsistent statement differs from hearsay because it may be offered to show inconsistency rather than to prove the truth of the earlier statement. It differs from impeachment because impeachment is the broader process of attacking credibility.
