Supreme Court of Alabama December 15, 1885 (Brown v. State)

OLOPTON, J.

A witness may be impeached, not only by proving that, at other times, he has made statements contradictory of, or inconsistent with those he makes on the trial, but also by proving that, on a former occasion, and under circumstances when it was his duty to state the whole truth, he omitted in his statement facts to which he testifies on the trial.
