Maine Rule 606 is substantially similar to Federal Rule 606, except that the Maine Rule includes language broadening the contexts in which a juror may not be called as a witness. Also, Maine has not adopted an exception to 606(b)(2) for testimony about a mistake in entering the verdict on a verdict form.70 These distinctions have been carried over as part of the restyling process.
Federal Restyling Committee Note
The language of Rule 606 has been amended as part of the 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 to change any result in any ruling on evidence admissibility.
