Osbaldo Esparza-Gonzalez, who is Latino, appeals from his conviction, under 8 U.S.C. § 1326(a), for being an alien unlawfully present in the United States after an earlier removal. Esparza-Gonzalez alleges that two Equal Protection violations under
Batson v. Kentucky,
FACTUAL AND PROCEDURAL BACKGROUND
On December 17, 2003, Esparza-Gonza-lez was indicted and charged with a violation of 8 U.S.C. § 1326(a) for being an alien found in the United States without permission after a prior removal. Espar-za-Gonzalez pled not guilty and was tried by a jury on February 17, 2004.
The district court used what is known as the “struck jury” system to select jurors for Esparza-Gonzalez’s trial. 1 Under this system, 32 venirepersons are initially selected, of whom 28 are potential jurors and four are potential alternates. Beginning with the defense, each side exercises its challenges for cause and then its peremptory strikes on an alternating basis. Because Esparza-Gonzalez was charged with a felony, the defense had ten peremptory strikes and the prosecution had six. See Fed.R.Crim.P. 24(b)(2). Each side received one additional peremptory strike for the alternate jurors. See id. at (c)(4)(A).
After the voir dire, neither side exercised a single strike for cause. If each side had used all its peremptory strikes, only a jury of 12 individuals and two alternates would have remained. 2 The defense exercised all of its ten peremptory strikes, but the prosecution only used one peremptory strike, waiving the remainder. Under the struck jury system, when either side waives a peremptory strike, this results in an excess number of potential jurors, and therefore, the juror with the highest juror number is removed from the jury panel. For this reason, a waiver of a peremptory strike under this system is properly viewed as the effective removal of an identifiable juror. In contrast, when a peremptory strike is waived under other jury selection systems, no juror is removed from the venire and the composition of the panel is left unchanged. Under these systems, it is only when a party exercises a peremptory strike or a strike for cause that the composition of the venire changes and a previously unidentified prospective juror is randomly selected to join the veni-re. 3
Of the 28 potential jurors, only three were persons of color, one of whom had a Latino surname. Among the four potential alternates, there was one individual with a Latino surname and no other individual of color. With the one peremptory strike it exercised against the potential jurors, the prosecution removed a white juror. By waiving its second peremptory strike, the prosecution removed the only *900 potential juror with a Latino surname, Ms. Martinez, who was juror number 28. 4 Defense counsel immediately challenged her removal under Batson, alleging that the prosecutor waived this strike with the discriminatory intent to remove the sole prospective Latino juror. The district court asked the prosecutor to respond to the challenge, and the prosecutor stated that he was waiving all his remaining strikes.
The district court initially found a Bat-son violation with respect to the removal of juror Martinez and ordered the clerk to dismiss the next juror in line, number 27, instead of juror Martinez. When the prosecutor objected, the district court noted that it could “take judicial notice of the fact that [the prosecutor], in many cases, most cases,” exercised all or most of his peremptory strikes and therefore that his failure to do so in this case permitted an inference of intentional discrimination.
After more discussion, the district court retreated from its initial finding of intentional discrimination and asked defense counsel whether she had any evidence on “how often the government waived [peremptory] challenges in the past or exercised challenges.” Defense counsel replied that during her last illegal re-entry case, another prosecutor from the same office waived a peremptory strike, resulting in the removal of a minority venireperson. The district court then ordered a short recess to research case law on whether waiver of a peremptory strike could constitute a
Batson
violation. When court resumed, the district court ultimately ruled that the defense had failed to establish a
prima facie
case of intentional discrimination. The district court relied on
State v. Paleo,
After the 12 jurors were selected, each side was allowed to exercise a peremptory strike against the four alternate jurors. If each side had used its strike only two alternates would have remained. The same selection rules applied to the selection of the alternates, and when the prosecutor waived his peremptory strike, the only alternate with a Latino surname, Mr. Lopez, was removed. The defense also challenged this removal under Batson, and in response the district court asked the prosecutor to explain the only peremptory strike he exercised. (This was the peremptory strike previously exercised against a potential juror.) The prosecutor said he struck that potential juror because he was divorced, worked in maintenance, and “didn’t strike [him] as the type of person that would be particularly attentive.” Defense counsel pointed out that several of the remaining jurors were divorced and one worked in maintenance, yet the prosecutor had not used his remaining five peremptory strikes to remove these potential jurors. Nevertheless, the district court found that the defense failed to establish a prima facie showing of intentional discrimination. The court did, however, require the record to be certified so that other judges might determine whether a pattern existed at the U.S. Attorney’s office of waiving peremptory strikes in order to unseat jurors of color. The jurors and alternates empaneled to hear Esparza-Gonzalez’s case included one person of color, who did not have a Latino surname.
*901 The jury found Esparza-Gonzalez guilty of being an alien present in the United States without permission after a prior removal under 8 U.S.C. § 1326(a). On April 27, 2004, the district court applied USSG § 2L1.2(b)(l)(A)(I) to increase Es-parza-Gonzalez’s sentence due to his prior drug trafficking conviction, for which he was sentenced to over thirteen months in prison. Based on this enhancement, the district court sentenced Esparza-Gonzalez to 57 months imprisonment, the low-end of the applicable sentencing range and well under the 10-year statutory maximum set out in 8 U.S.C. § 1326(b)(4). Although no proof of his prior conviction was presented to the jury, Esparza-Gonzalez did not object to the accuracy or use of this conviction at the time of sentencing. Without this enhancement, the sentencing range would have been only four to ten months. See USSG ch. 5, pt. A, sentencing table (2004). Esparza-Gonzalez timely appealed his conviction and sentence to this court.
STANDARD OF REVIEW
We review de novo the question of whether a district court must apply
Batson
to a defendant’s claim of intentional racial discrimination.
See United States v. Alanis,
DISCUSSION
I. The Batson Challenges
A. Waiver of Peremptory Strikes Can Form the Basis of a Batson Challenge
In
Batson,
the Supreme Court held that a “[sjtate’s privilege to strike individual jurors through peremptory challenges, is subject to the commands of the Equal Protection Clause.”
5
Whether under the struck jury system waivers of peremptory strikes can form the basis of a
Batson
challenge is a question of first impression. In denying that they can, the district court relied on a case decided by the Arizona Supreme Court.
Paleo,
In
Paleo,
the Arizona Supreme Court incorrectly concluded that peremptory strikes and the waiver of these strikes differ because the former require action, while the latter simply inaction.
For this reason, the struck jury system has long been criticized for allowing the racial engineering of juries.
See, e.g., United States v. Blouin,
The Supreme Court recently held that jury selection procedures may give rise to an inference of discriminatory intent even though the prosecutor is not actively striking potential jurors. In
Miller-El v. Dretke,
— U.S. -,
Similarly, the struck jury system allows parties who intentionally want to remove jurors for discriminatory reasons to camouflage these removals by unseating jurors through the waiver of peremptory strikes rather than resorting to direct removals by using peremptory strikes. It is clear that under the struck jury system, the waiver of peremptory strikes, just like the exercise of these strikes, allows those of “a mind to discriminate” to do so.
See Batson,
The government correctly notes that it is not required to exercise all of its peremptory challenges and that it was well within its rights to waive five of its six peremptory strikes in this case. In the abstract, this is of course true. The use of peremptory strikes has long been recognized as a capricious and arbitrary right used at the will of the striking party.
See Pointer v. United States,
B. The Challenge to Juror Lopez
Having determined that, under the struck jury system, waivers of peremptory strikes should be treated as effective peremptory strikes, we begin our analysis of Esparza-Gonzalez’s specific
Batson
challenges with the last juror challenged, juror Lopez. We conclude that EsparzaGonzalez established
a prima facie
case of intentional discrimination with respect to juror Lopez’s removal from the pool of alternate jurors. To establish a
prima facie
case, Esparza-Gonzalez must show that (1) he is a member of a cognizable group; (2) the prosecutor has removed members of such a group; and (3) the totality of the circumstances gives rise to an inference that the prosecutor excluded jurors based on race.
Fernandez v. Roe,
Although our precedent does not require a pattern of removing people of color to establish a
prima facie
case of a
Batson
violation,
see United States v. Vasquez-Lopez,
Esparza-Gonzalez, however, has presented much more than this pattern of removal to support a
prima facie
showing. First, the prosecutor’s actions during the jury selection process provide further support, when viewing the totality of the circumstances, for an inference of intentional
*905
discrimination. The prosecutor’s effective strikes of potential alternate juror Lopez and potential juror Martinez after waiving his opportunity to pose
any
direct questions to the venire panel contributes to an overall inference of discriminatory intent.
See Fernandez,
Mr. Lopez was the only veniremember to respond affirmatively to the district court’s question of whether anyone traveled to Mexico approximately once every two years. Mr. Lopez stated that he took leisure trips to places like Cancún. In addition, the judge asked each juror to state for the court “where [they] live and what [they] do for a living, if [they] work outside the home, if [they’re] married ... [and] what [their] spouse does for a living.” The record does not indicate that juror questionnaires were used for voir dire, and the prosecutor declined the opportunity to ask additional direct voir dire questions after the district court finished its questioning. At the time he waived the peremptory strike causing the removal of juror Lopez, the prosecutor had very little hard information to base this decision on. Although the prosecutor has no obligation to question all potential jurors, his failure to do so prior to effectively removing a juror of a cognizable group through a waiver may contribute to a suspicion that this juror was removed on the basis of race. This suspicion, along with other factors, may lead to an inference of intentional discrimination.
Second, the judicial notice taken, at least initially, by the district court of the prosecutor’s usual practice of exercising all or most of his peremptory strikes further supports an inference of intentional discrimination, in light of the totality of the circumstances. Third, the defense counsel’s statement that another prosecutor from the same office had recently waived peremptory strikes to remove minority jurors in another illegal re-entry case also buttresses the defendant’s case that the totality of the circumstances created an inference of discriminatory intent.
Finally, while illegal re-entry is not necessarily a racially charged crime, in this case, Esparza-Gonzalez is a Mexican national and thus race is clearly involved in the proceeding. This fact is one that should also be considered when evaluating whether the totality of the circumstances gives rise to an inference of discriminatory intent. Presumably recognizing the racial element inherent in the trial, the district court asked all jurors during voir dire whether “the fact that the defendant is Hispanic, would ... in any way influence
*906
any of you in making a decision in this case.”
See Simmons v. Beyer,
Because the district court never required the prosecution to articulate a race-neutral reason for juror Lopez’s removal, we remand for an evidentiary hearing to allow the prosecution to present evidence of the actual reason for this removal.
See Paulino v. Castro,
C. The Challenge to Juror Martinez
Initially, the district court determined that the defense established a prima facie case under Batson with respect to the removal of juror Martinez and asked the prosecutor for a response to the challenge. The prosecutor responded that he was “waiving the rest” of his peremptory strikes. The district court was not satisfied with this race-neutral explanation for the removal of juror Martinez and instructed the clerk to strike the next juror in line instead of juror Martinez. The prosecutor objected to the district court’s conclusion that he intentionally discriminated against juror Martinez and eventually convinced the district court to reassess this Batson challenge.
The Supreme Court has held that when a party articulates a race-neutral reason for a challenged strike and the trial court proceeds to the last step of the
Batson
inquiry to determine whether the party intentionally discriminated in making the strike, the initial question of whether a
prima facie
showing was established is moot before the reviewing court.
Hernandez v. New York,
In
Aikens,
as in the case at hand, the district court initially concluded that a
pri-ma facie
case of intentional discrimination had been established, but later returned to this question instead of focusing on the ultimate inquiry of racial discrimination
vel non. Id.
at 714-15 & n. 4,
We disagree with Esparza-Gonzalez’s contention that this error on the part of the district court is structural and requires reversal of his conviction. As the Supreme Court did in Aikens, we remand to the district court for a determination of the ultimate Batson issue — was the removal of potential juror Martinez the result of intentional discrimination — with Esparza-Gonzalez bearing the burden of persuasion. We realize, of course, that the district court at one point did conclude that there had been intentional discrimination. However, because the court later withdrew that determination, we think the best course of action is to remand to the district court.
II. Sentencing Challenge
Esparza-Gonzalez argues that his Sixth Amendment rights were violated when the district court increased his sentence by sixteen levels based on his prior conviction for drug trafficking, a fact not found by the jury convicting him for illegal re-entry. The Supreme Court has made clear, however, that enhancements based on prior convictions need not be proven beyond reasonable doubt by a jury or admitted by the defendant to satisfy the Sixth Amendment.
United States v. Booker,
— U.S. -,
Esparza-Gonzalez seeks a remand based on the fact that he was sentenced under the mandatory sentencing regime.
See United States v. Moreno-Hernandez,
■ CONCLUSION
Based on the foregoing discussion, we REVERSE the district court’s finding that the defendant failed to establish a prima facie case of discrimination with respect to juror Lopez and REMAND to the district court to determine if a race-neutral explanation for the exclusion can be provided and if this explanation is merely pretext for discrimination. We also REMAND the challenge regarding juror Martinez for further proceedings to allow the district court to revisit its earlier determination as to whether intentional discrimination occurred contrary to Batson such that a new trial is merited. Lastly, we REMAND Esparza-Gonzalez’s sentence to the district court.
Reversed in part and remanded in part.
Notes
. The district court referred to the jury selection procedure used as the “modified Arizona system.”
. If either side had requested and been granted a strike for cause, the ideal number of jurors and alternate jurors would have been reached before each side had exercised all of its peremptory strikes.
. For example, under the "jury box” system 12 prospective jurors are seated and subjected to voir dire. When a party exercises any challenge — peremptory or for cause — a new juror is brought in to replace the excused juror. The jury box system, then, allows less manipulation of the entire composition of the jury than the struck jury system permits. See Bettina B. Plevan, Jury Trial Issues, in Current Developments in Federal Civil Practice, 706 PLI/Lit 443, 451-52 (2004).
. The record does not reveal whether Ms. Martinez is Latina or Native American, which was the subject of speculation by the court. Voir dire revealed that Ms. Martinez works for a Native American tribe and has a Latino surname, which may be her maiden name or could be a name acquired through marriage.
. This analysis applies in federal criminal cases as well.
See Buckley v. Valeo,
. Two Texas Appellate Courts previously considered, and rejected, the use of a peremptory strike waiver as a basis for a
Batson
challenge.
See Mayes v. State,
. See Plevan, 706 PLI/Lit at 451-52 ("For good or for ill, the 'jury box’ method focuses on the selection of individual jurors and does not allow the shaping of an entire jury. Counsel have no way of knowing ... who will replace the challenged juror. This means that counsel must decide who to strike based on the individual’s qualities, rather than whether that person is better or worse than the replacement.”).
