The court may not receive a juror's affidavit or evidence of a juror's statement on these matters.(2)Exceptions.

This rule has been amended to conform to Federal Rule of Evidence 606, including the addition of subdivision (b)(2)(C). However, subsection (b) has not been applied to criminal cases, as is done in Federal Rule of Evidence 606(b), because the matter is covered by Arizona Rule of Criminal Procedure 24.1(d).
Additionally, the language of Rule 606 has been amended to conform to the federal restyling of the Evidence Rules to make them more easily understood and to make style and terminology consistent throughout the rules. These changes are intended to be stylistic only. There is no intent in the restyling to change any result in any ruling on evidence admissibility.
