Sаkhawat Ullah and Mary Katherine Gosho-Kim appeal their convictions on counts of transporting illegal aliens within the United States in violation of 8 U.S.C. § 1324(a)(1)(B) and 18 U.S.C. § 2. Among other things, Ullah and Gosho-Kim contend that the district court improperly empaneled a fourteen-person jury and permitted it to deliver a nonunanimous guilty verdict. They are correct. 1
During jury selection, the district court chose fourteen people — twelve jurors and two alternates — to serve as Ullah and Gosho-Kim’s jury. In the course of the two-week trial, the attention of one of the alternate jurors began to flag, and she asked to be excused. The district court believed, perhaps correctly, that the problem with the alternate juror was caused by her realization that she would be unable to deliberate with the regular jurors and otherwise participate in the outcome of the trial.
See United States v. Olano,
The district court, sua sponte, proposed to remedy the alternate juror problem by permitting the two alternates to deliberate and vote with the regular jurors — in effect, creating a fourteen-person jury. The district court also suggested that the reconstituted fourtеen-person jury be permitted to deliver a nonunanimous verdict as long as twelve of the fourteen jurors agreed on conviction or acquittal. The transcript reveals the following dialogue between the district court, the prosecutor, and the attorneys for Ullah and Gosho-Kim:
The Court: I have disсussed this earlier with you, about all the alternates. I cannot make you stipulate to this, but if [an alternate juror] asks the question, that she legitimately should ask: “Am I going to have to listen to this, and pay attention, and then go home without participating?”
My question to you is — and what I would recommend to you, in any casе, is that we allow all of the jurors to deliberate, and — the way I would do it is to let them deliberate and to vote, *511 and the minute there are twelve votes for conviction, or acquittal, the jury can return a verdict. So one of those votes might be the alternate.
Do you object to that?
Mr. Albert [AUSA]: I will do whatever the defense wants to do on this one.
The Court: Okay. Mr. Callaway [attorney for Ullah]?
Mr. Minker [attorney for Gosho-Kim]: Excuse me. I have no objection to the one juror being excused. We can take care of that.
The Court: Okay. The next problem—
Mr. Minker: I don’t know about [Mr. Calla-way].
Mr. Callaway: I have no objection.
Mr. Minker: So now we’re down to 13.
The Court: We’re down to 13.
Mr. Minker: Can we consult with our client, Judge?
The Court: For a split second.
Mr. Minker: I don’t have any problem with that, Judge. I’ve talked it over with my client—
The Court: Okay.
Mr. Callaway: We have no objection.
The Court: All right.
Mr. Minker: I think the record ought to show that we have consulted with our clients, and our clients have no objection.
The Court: All right.
Mr. Albert: I don’t think I want to have 14 jurors arguing on this case, Judge.
The Court: Why?
Mr. Albert: I don’t know.
The Court: Well, then, you stand up and tell the two that they’re excused.
Mr. Albert: I’ll go along if the defense wants to go along with this one.
The Court: All right. How about 14?
It’s whatever you all want to do.
Mr. Callaway: That’s fine. I don’t have any problem with it.
Mr. Minker: I don’t have any problem. The Court: All right. Get the jury.
After the jury instructions were delivered, all fourteen jurors (the twelve regular jurors and the two alternates) retired to deliberate and determine Ullah and Gosho-Kim’s fate. Several hours later, the jury returned with a verdict. Ten of the regular jurors and both of the alternate jurors voted to convict both defendants on six counts of transpоrting illegal aliens in the United States. Two of the regular jurors voted to acquit Ullah and Gosho-Kim on these charges. The vote thus was either 12-2 or 10-2 in favor of conviction, depending upon whether one includes the votes of the alternate jurors in the tally. Based upon that vote, the district court entered judgmеnts of conviction against Ullah and Gosho-Kim on the six counts. Both defendants timely appealed.
The district court’s failure to excuse the alternate jurors prior to the beginning of deliberations and its concomitant decision to include them in that process may run afoul of a number of rules governing the conduct of federal criminal proceedings. First, we could conclude that the district court’s action permitting the alternate jurors to participate in the jury’s deliberations violated Fed.R.Crim.P. 24(c), which states that “[a]n alternate juror who does not replace a regular juror shall be discharged after the jury retires to consider its verdict.”
See Olano,
*512
The district court’s decision to create, in effect, a fourteen-person jury also may have violated Fed.R.Crim.P. 23(b), which states that “[jjuries
shall be
of 12” persons and which permits waivers of that requirement solely if “in writing” and, even then, permits the creation of juries only with
“less
than 12” members. Fed.R.Crim.P. 23(b) (emphases added). The plain language of that rule is mandatory in nature and does not apрear to allow even the consensual creation of a fourteen-person jury: that plain language generally is determinative.
See Price v. Commissioner,
We need not base our holding on a determination that the district court’s actions violated Rule 24(c) or Rule 23(b), however, because we conclude that the decision to permit a
nonunanimous
verdict by the jury (regardless of how many members it contains) indisputably constitutes reversible error. Fed.R.Crim.P. 31(a) explicitly requires that “[tjhe verdict shall be unanimous”: that requirement cannot be waived.
See United States v. Lopez,
Despite the overwhelming and irrefutable authority to the contrary, the government urges us to adopt the singular view of the Eleventh Circuit, which permits the unanimity requirement of Rule 31(a) to be waived by a defendant “in exceptional cir
*513
cumstances”.
See Sanchez v. United States,
The government finally contends that Ullah and Gosho-Kim cannot raise the “nonunanimous jury” issue on appeal because they did not object in the district court to the decision to permit a nonunanimous verdict. However, if, as here, a right or requirement cannot be waived, a party need not object to its deprivation in order to preserve the issue for appeal. Moreover, the issue is purely one of law and the record has been fully developed: it therefore can be raised for the first time on appeal.
See United States v. Reyes-Alvarado,
Ullah, unlike Gosho-Kim, did not raise the issue of the validity of the non-unanimous jury verdict in his opening brief: he raised it only in his reply brief. We “will not ordinarily consider matters on appeal that are not specifically and distinctly argued in apрellant’s opening brief.”
Miller v. Fairchild Industries, Inc.,
Each of these three exceptions is applicable here. First, it is “plain error” for a conviction to be based upon an nonunаni-mous verdict: reversal of such an error is “necessary to prevent a miscarriage of justice,” Bus
tillo,
Two jurors voted to acquit Ullah and Gosho-Kim: the defendant’s convictions were not supported by the verdict of a unanimous jury. The verdict violated Rule 31 as well as the “firmly established” and “indispensable” requirements of our federal system. Accordingly, the convictions are reversed, аnd the case is remanded for proceedings consistent with this opinion.
REVERSED and REMANDED.
Notes
. The other events complained of by Ullah and Gosho-Kim may not recur on retrial and do not include a claim that the evidence was insufficient to support their convictions: we therefore decline to reach thosе issues.
. Compare id. at 1436 ("[R]ule 24(c) is phrased in unmistakably mandatory language and does not expressly provide for any waiver....”) with id. at 1437 (noting that courts have allowed Rule 24(c) to be waived under some circumstances).
. Although Ullah and Gosho-Kim’s attorneys stated that they had consulted with their clients and that Ullah and Gosho-Kim had no objection ■ to the district court’s suggestions, under Olano, such a waiver is invalid: criminal defendants must personally waive the requirements of Rule *512 24(c). See id. at 1437 (establishing and noting justifications for that requirement).
. The government asserts that these cases only require a unanimous verdict from a jury comprised of twelve persons, and that the nonunani-mous verdict here was permissible because it was from a fourteen-persоn jury in which twelve persons agreed with the verdict. That argument is perilously close to frivolous. The language of Rule 31(a) does not differentiate between twelve- and fourteen-person juries, nor is a verdict legitimate whenever twelve persons agree on it despite the presence of оne, two, six, eleven, or a thousand dissenting jurors.
. Unlike criminal defendants in state courts, Ullah and Gosho-Kim’s also have a federal
constitutional
right to a unanimous verdict by virtue of their presence in federal court.
See Johnson v. Louisiana,
The historical foundation of the requirement that jury verdicts in federal criminal trials be unanimоus indicates that a defendant cannot waive that component of a federal proceeding. Five justices of the Supreme Court have concurred in the view that unanimity is unalterably required in federal criminal prosecutions.
See id.
. In any case, Ullah and Gosho-Kim’s purported “waiver” of the requirement of jury unanimity would be invalid even under the Eleventh Circuit’s
Sanchez
exception.
Sanchez
merely allowed a defendant to waive that requirement "in exceptional circumstances”.
Sanchez,
Those requirements were not met in this case; indeed, none of those preconditions were met here. Moreover, the judgе explicitly gave the defendants only “a split second” to consult with counsel and determine whether or not to waive their rights, made a point of "recommending” the solution he had proposed, and explicitly coerced at least one of the parties (the government) to withdraw its objection to his "recommendation”. See supra at 510-11. Under such circumstances, Ullah and Gosho-Kim’s purported waiver unquestionably would not be "knowingly and voluntarily made” and hence would be invalid.
