Notes of Advisory Committee on Rules
Subdivision (a). The considerations which bear upon the permissibility of testimony
by a juror in the trial in which he is sitting as juror bear an obvious similarity to those
evoked when the judge is called as a witness. See Advisory Committee's Note to Rule 605.
The judge is not, however in this instance so involved as to call for departure from
usual principles requiring objection to be made; hence the only provision on objection
is that opportunity be afforded for its making out of the presence of the jury. Compare
Rules 605.
Subdivision (b). Whether testimony, affidavits, or statements of jurors should be received
for the purpose of invalidating or supporting a verdict or indictment, and if so, under
what circumstances, has given rise to substantial differences of opinion. The familiar rubric
that a juror may not impeach his own verdict, dating from Lord Mansfield's time, is a gross
oversimplification. The values sought to be promoted by excluding the evidence include
freedom of deliberation, stability and finality of verdicts, and protection of jurors against
annoyance and embarrassment. McDonald v. Piess, 238 U.S. 264 (1915). On the other
hand, simply putting verdicts beyond effective reach can only promote irregularity and injustice.
The rule offers an accommodation between these competing considerations.
The mental operations and emotional reactions of jurors in arriving at a given result would,
if allowed as a subject of inquiry, place every verdict at the mercy of jurors and
invite tampering and harassment. See Grenz v. Werre, 129 N.W.2d 681 (N.D. 1964). The
authorities are in virtually complete accord in excluding the evidence. Fryer, Note on
Disqualification of Witnesses, Selected Writings on Evidence and Trial 345, 347 (Fryer ed.
1957); Maguire, Weinstein, et al., Cases on Evidence 887 (5th ed. 1965); 8 Wigmore
§ 2340 (McNaughton Rev. 1961). As to matters other than mental operations and emotional
reactions of jurors, substantial authority refuses to allow a juror to disclose irregularities
which occur in the jury room, but allows his testimony as to irregularities occurring
outside and allows outsiders to testify as to occurrances both inside and out. 8 Wigmore
§ 2354 (McNaughton Rev. 1961). However, the door of the jury room is not necessarily
a satisfactory dividing point, and the Supreme Court has refused to accept it for every
situation. Mattox v. United States, 146 U.S. 140 (1892).
Under the federal decisions the central focus has been upon insulation of the manner in
which the jury reached its verdict, and this protection extends to each of the components
of deliberation, including arguments, statements, discussions, mental and emotional reactions,
votes, and any other feature of the process. Thus testimony or affidavits of jurors have
been held incompetent to show a compromise verdict, Hyde v. United States, 225 U.S.
347, 382 (1912); a quotient verdict, McDonald v. Piess, 238 U.S. 264 (1915); speculation
as to insurance coverage, Holden v. Porter, 495 F.2d 878 (10th Cir.1969), Farmers Coop.
Elev. Ass'n v. Strand, 382 F.2d 224, 230 (8th Cir. 1967), cert. denied 389 U.S. 1014;
misinterpretations of instructions, Farmers Coop. Elev. Ass'n v. Strand, supra; mistake
in returning verdict, United States v. Chereton, 309 F.2d 197 (6th Cir. 1962); interpretation
of guilty plea by one defendant as implicating others, United States v. Crosby, 294 F.2d
928, 949 (2d Cir. 1961). The policy does not, however, foreclose testimony by jurors
as to prejudicial extraneous information or influences injected into or brought to
bear upon the deliberative process. Thus a juror is recognized as competent to testify
to statements by the baliff or the introduction of a prejudicial newspaper account into the
jury room, Mattox v. United States, 146 U.S. 140 (1892). See also Parker v. Gladden, 385
U.S. 363 (1966).
This rule does not purport to specify the substantive grounds for setting aside verdicts
for irregularity; it deals only with the competency of jurors to testify concerning
those grounds. Allowing them to testify as to matters other than their own inner reactions
involves no particular hazard to the values sought to be protected. The rules is based
upon this conclusion. It makes no attempt to specify the substantive grounds for setting
aside verdicts for irregularity.
See also Rule 6(e) of the Federal Rules of Criminal Procedure and 18 U.S.C. § 3500,
governing the secrecy of grand jury proceedings. The present rules does not relate to secrecy
and disclosure but to the competency of certain witnesses and evidence.
Notes of Committee on the Judiciary, House Report No. 93-650
As proposed by the Court, Rule 606(b) limited testimony by a juror in the course of an
inquiry into the validity of a verdict or indictment. He could testify as to the influence
of extraneous prejudicial information brought to the jury's attention (e.g. a radio newscast
or a newspaper account) or an outside influence which improperly had been brought to bear
upon a juror (e.g. a threat to the safety of a member of his family), but he could
not testify as to other irregularities which occurred in the jury room. Under this formulation
a quotient verdict could not be attacked through the testimony of a juror, nor could
a juror testify to the drunken condition of a fellow juror which so disabled him that
he could not participate in the jury's deliberations.
The 1969 and 1971 Advisory Committee drafts would have permitted a member of the jury
to testify concerning these kinds of irregularities in the jury room. The Advisory Committee
note in the 1971 draft stated that "the door of the jury room is not a satisfactory
dividing point, and the Supreme Court has refused to accept it." The Advisory
Committee further commented that—
The trend has been to draw the dividing line between testimony as to mental processes, on the one hand, and as to the existence of conditions or occurrences of events calculated improperly to influence the verdict, on the other hand, without regard to whether the happening is within or without the jury room. . . . The jurors are the persons who know what really happened. Allowing them to testify as to matters other than their own reactions involves no particular hazard to the values sought to be protected. The rule is based upon this conclusion. It makes no attempt to specify the substantive grounds for setting aside verdicts for irregularity.Objective jury misconduct may be testified to in California, Florida, Iowa, Kansas, Nebraska, New Jersey, North Dakota, Ohio, Oregon, Tennessee, Texas, and Washington.
[L]et it once be established that verdicts solemnly made and publicly returned into court can be attacked and set aside on the testimony of those who took part in their publication and all verdicts could be, and many would be, followed by an inquiry in the hope of discovering something which might invalidate the finding. Jurors would be harassed and beset by the defeated party in an effort to secure from them evidence of facts which might establish misconduct sufficient to set aside a verdict. If evidence thus secured could be thus used, the result would be to make what was intended to be a private deliberation, the constant subject of public investigation--to the destruction of all frankness and freedom of discussion and conference. [238 U.S. 264, at 267 (1914).]As it stands then, the rule would permit the harassment of former jurors by losing parties as well as the possible exploitation of disgruntled or otherwise badly-motivated ex-jurors.
