Witness-Competence

Question 1

Is there’s a misunderstanding/mistake amongst jurors in which they all share the same misunderstanding, can a juror testify as to that issue?

Answer 1

A juror cannot testify as to the mental processes that he or any other juror used in arriving at a verdict, or the validity of a verdict even when those mental processes reflect a misunderstanding of the law. The mere fact that the verdict is based on a mistake, even one made by all of the jurors, is insufficient to permit a juror to impeach the verdict

Question 2

Can jurors testify before other jurors after the trial has concluded and the verdict has been rendered?

Answer 2

Limitation on a juror testifying as a witness before the other jurors only applies during the trial, and not after it has concluded.
