Tanner v. U.S.
Court U.S. Supreme Court
Date decided


Tanner is convicted. Jurors come forward and say jurors were partying during deliberations. Tanner wants to impeach verdict on appeal.


Follow Rule 606(b): No juror may testify about jury deliberations to impeach the verdict that the jury has reached.

  • The evidence (jurors committing felonies) is INADMISSIBLE


We have faith and trust in the jury in the back end (i.e., their verdict stands)

  • We actively don’t want the jury to explain reasoning/mess-ups
  • Because of this, we have to be particularly careful what we show them on the front end
