MICHAEL DALY HAWKINS, Circuit Judge:This case asks us to reconsider the longstanding principle that automatic reversal of a conviction is the proper remedy where a trial court erroneously deprives a criminal defendant of the right of peremptory challenge.
Following a jury trial, defendant-appellant Richard Annigoni (“Annigoni”) was convicted of bank fraud in violation of 18 U.S.C. § 1344. Annigoni appealed his conviction on two grounds. He challenged the district court’s pre-trial ruling limiting cross-examination of a government witness, and challenged the district court’s refusal, on Bat-son1 grounds, to allow him to exercise a peremptory challenge to remove an Asian-American juror from the panel. He argued that the district court had erroneously denied his right of peremptory challenge, and that reversal of his conviction was therefore required.
*1134A three-judge panel of this Circuit affirmed Annigoni’s conviction. United States v. Annigoni, 57 F.3d 739 (9th Cir.1995), as amended, 68 F.3d 279. The panel upheld the district court’s decision to limit the scope of cross-examination of the government witness. It went on to find that the district court had erred in denying Annigoni’s peremptory challenge, but concluded that the error did not require automatic reversal of his conviction. Applying a harmless-error analysis, the panel concluded that the error in Annigoni’s ease was harmless because Annigoni “failed to show that any juror challengeable for cause sat on his case. He lost one peremptory he should have had. He did not lose an impartial jury.” Annigoni, 68 F.3d at 285.
Annigoni petitioned this Court for rehearing en banc pursuant to Federal Rule of Appellate Procedure 40. We granted rehearing to consider whether the erroneous denial of Annigoni’s right of peremptory challenge required automatic reversal. For reasons discussed below, we reverse the district court and hold that the erroneous denial of a criminal defendant’s right of peremptory challenge requires automatic reversal.
FACTS
I. Events underlying Annigoni’s indictment
Annigoni’s conviction arises out of a series of fraudulent financial transactions that secured him a $2.85 million loan on which he and his associates later defaulted. The transactions centered on the purchase of an office building in Anaheim, California. The office building was constructed by El Rancho North, a partnership that financed the project with a $1.45 million loan from Prudential Insurance Company. At the time of the transactions underlying this case, El Rancho still owed Prudential approximately $950,000 on the loan.
In conjunction with co-defendant Ronald Fauria, a senior vice-president of Orange Coast Title Company, and James Perumean, a dentist and real estate investor, Annigoni formed a limited partnership. Annigoni’s and Fauna’s interests were concealed, while Perumean acted as front man for the limited partnership.
On behalf of the limited partnership, Peru-mean sought a $2.85 million loan from the United California Savings Bank. In applying for the loan, Perumean represented to the bank that the partnership had the chance to buy the property for $4 million. He told the bank that the partnership needed a $2.85 million loan to acquire title to the property and to pay off the first trust deed holder, Prudential Insurance Company. Perumean represented to the bank that the loan would be secured by that first trust deed. Perume-an also represented to the bank that the property was owned by Par Western Interests, Inc., a company Annigoni owned.
In fact, Par Western did not own the property, but manipulated escrow accounts at Orange Coast Title Company to mislead the bank. The scheme worked as follows: Par Western arranged to acquire the property on the same day it was due to be sold to the limited partnership. Fauria set up a double escrow account at the title company to handle two closings on the property simultaneously. In the first escrow, Par Western purportedly delivered title to the limited partnership. The bank simultaneously transferred the $2.85 million in loan proceeds to a second escrow. Of that $2.85 million, $1.84 million was paid to the property’s true owner, El Rancho North; the rest of the cash was disbursed to Annigoni’s wife, in-laws, and lawyers, as well as to Fauria.
Contrary to Perumean’s representations to the bank, the limited partnership never paid off the first trust deed. Duped by false documents, the bank did not discover the fraud until two years later, when the borrowers defaulted on the loan.
Appellant Annigoni and co-defendant Fau-ria were indicted for defrauding a bank in violation of 18 U.S.C. § 1344 and for aiding and abetting in the making of a false statement to a federally-insured bank in violation of 18 U.S.C. § 1014.
II. Jury selection
The rehearing of this appeal arises out of the district court’s denial of one of Annigoni’s *1135peremptory challenges during jury selection. In the proposed voir dire questions Annigoni submitted to the district court, he included the following question: “Have you, or has anyone close to you, ever joined a limited partnership?” When the district court posed that question to the jury panel, potential juror Jue Horn raised his hand and the following colloquy ensued:
THE COURT: Tell me a little bit about that experience.
MR. HOM: I have a joint partnership with the brokerage house — Merrill Lynch.
THE COURT: You invested in one of the Merrill Lynch limited partnerships?
MR. HOM: Yes.
THE COURT: All right. Was that in oil and gas or real estate, or what type of investment was it?
MR. HOM: Mostly it’s properties.
THE COURT: And your investment in that is strictly as a passive investor?
MR. HOM: Yes, sir.
The district court next asked the jury pool whether any of them had been involved in litigation. Two potential jurors raised their hands, including Mr. Horn, who engaged the court in the following colloquy:
MR. HOM: Yes, on that investment through Merrill Lynch, I don’t know if they have any allegation going on at this time which I don’t know anything about— in the partnership.
THE COURT: All right. Do you suspect that there was any litigation regarding that investment? Have you received any notices about it?
MR. HOM: Not one in the past three months or so.
THE COURT: All right. How about in the past year?
MR. HOM: I have taken no action on that.
When the defense attempted to exercise a peremptory challenge against Mr. Horn, the government objected pursuant to Batson v. Kentucky, 476 U.S. 79, 106 S.Ct. 1712, 90 L.Ed.2d 69 (1986), which prohibits the use of peremptory challenges in a racially discriminatory manner.2 During a sidebar conference, the following colloquy occurred:
THE COURT: All right, what’s your reasons?
MR. ANDRES (Counsel for Fauria): He has conservative investments. He has — I think he has various limited partnerships and investments. Because of his investment background, I think that it would be in my client’s best interest to have him excused from this jury.
THE COURT: He’s Asian.
MR. ANDRES: I understand that, and I think the Prosecution has kicked off number three, who was an Asian lady first strike out of the box. I don’t think we’ve struck any Asian prospective jurors.
MS. SUN (Counsel for Annigoni): Your Honor, can I just add to that? I believe the exchange between the Court and Mr. Horn was as follows — he indicated he hadn’t received any notices about legal action within the last three months. The Court then said, “Within the last year?”, and I think his answer was, “I didn’t take any action about those”, which suggests to me that he did get more information and, perhaps, just wasn’t willing to share. That made him, to me — that gave me some concern about the extent of those kinds of activities that he’s engaged in.
MS. LUM (the Prosecutor): Your Honor, I don’t — I didn’t interpret his answer that way. I don’t think he’s been involved in any litigation and there have been numerous minorities that have been on the panel and that have been struck by the Defen*1136dants. The fact that he is involved in limited partnerships — and it was in a very, very tangential way — he barely knew what it involved. I don’t think that’s sufficient reason to challenge.
THE COURT: I’m not going to allow the exercise of the peremptory challenge because I think it’s racially motivated.
As a result of the district court’s refusal to allow Annigoni to use one of his peremptory strikes, Mr. Horn was seated as a member of the jury that convicted Annigoni of bank fraud.
On appeal, the panel quickly disposed of the issue Annigoni raised: whether the district court erred when it denied the defense’s attempt to exercise a peremptory strike against Mr. Horn.3 Noting that the district court’s sole finding on the issue of discrimination was its observation, “He’s Asian,” the panel concluded that it was error to deny Annigoni a peremptory strike based on “the bare fact of a male juror of Asian heritage.” Although it acknowledged that a defendant may not use a peremptory challenge to discriminate on the basis of race, the panel invoked the Supreme Court’s recent decision in Purkett v. Elem, - U.S. -, 115 S.Ct. 1769, 131 L.Ed.2d 834 (1995), which established that unless a discriminatory intent is inherent in the explanation a litigant offers to defend a peremptory challenge, ‘“the reason offered will be deemed race neutral.’” Purkett, - U.S. at -, 115 S.Ct. at 1771 (quoting Hernandez v. New York, 500 U.S. 352, 360, 111 S.Ct. 1859, 1866, 114 L.Ed.2d 395 (1991)). Applying Purkett, the panel concluded that Annigoni’s defense attorney had offered an entirely plausible explanation for the proposed peremptory challenge: she wished to remove Mr. Horn because of his investment in a limited partnership that had been involved in litigation. Although that explanation did not, in the panel’s view, rise , to the level of “cause for challenge[,]” nonetheless it satisfactorily rebutted the government’s Batson challenge, since it was “distinct ... from a manifestation of racial prejudice.” Annigoni, 68 F.3d at 283.
We have long followed a rule requiring automatic reversal for errors of this kind. See United States v. Turner, 558 F.2d 535 (9th Cir.1977). While no intervening case has challenged its automatic reversal rule, Turner was decided prior to Batson and recent cases concerning the proper remedy for trial errors. Relying upon these recent trends, the panel analyzed the district court’s error under a harmless-error standard, and concluded that the error here was harmless. The issue before us on rehearing is whether a harmless-error analysis is the appropriate standard to use in reviewing the erroneous deprivation of a defendant’s right of peremptory challenge.
ANALYSIS
I. The law of peremptory challenges
A. The right of peremptory challenge
The peremptory challenge is one of the oldest established rights of the criminal defendant.4 For more than a century, the Supreme Court has recognized that “[the] making of [peremptory] challenges [is] an essential part of the trial[,]” Lewis v. United States, 146 U.S. 370, 376, 13 S.Ct. 136, 138, 36 L.Ed. 1011 (1892), and has described the right of peremptory challenge as “one of the most important of the rights secured to the accused.” Pointer v. United States, 151 U.S. 396, 408, 14 S.Ct. 410, 414, 38 L.Ed. 208 (1894). The significance of the right is underscored by the extraordinary remedy courts have traditionally afforded to defendants deprived of the right: reversal of conviction, without a showing of prejudice. Lewis, 146 U.S. at 376, 13 S.Ct. at 138. Courts have adhered to this remedy for well over a century. See Harrison v. United *1137States, 163 U.S. 140, 142, 16 S.Ct. 961, 961, 41 L.Ed. 104 (1896); Gulf, Colorado & Santa Fe Ry. Co. v. Shane, 157 U.S. 348, 351, 15 S.Ct. 641, 642, 39 L.Ed. 727 (1895); Swain v. Alabama, 380 U.S. 202, 212, 85 S.Ct. 824, 831, 13 L.Ed.2d 759 (1965), overruled on other grounds by Batson v. Kentucky, 476 U.S. 79, 106 S.Ct. 1712, 90 L.Ed.2d 69 (1986).
Peremptory challenges, along with challenges for “cause,” are the principal tools that enable litigants to remove unfavorable jurors during the jury selection process. The central function of the right of peremptory challenge is to enable a litigant to remove a certain number of potential jurors who are not challengeable for cause, but in whom the litigant perceives bias or hostility. “The function of the [peremptory] challenge is not only to eliminate extremes of partiality on both sides, but to assure the parties that the jurors before whom they try the case will decide on the basis of the evidence placed before them, and not otherwise.” Swain, 380 U.S. at 219, 85 S.Ct. at 835. A related and equally important purpose of peremptory challenges is to reassure litigants — particularly criminal defendants — of the fairness of the jury that will decide their case. More than two centuries ago, Blackstone declared the peremptory challenge “necessary ... that a prisoner ... should have a good opinion of his jury, the want of which might totally disconcert him,” and stated that “the law wills not that he should be tried by any one man against whom he has conceived a prejudice, even without being able to assign a reason for such dislike.” Blackstone, 4 Commentaries 353 (1st ed. 1769).
While not guaranteed by the Constitution, Stilson v. United States, 250 U.S. 583, 586, 40 S.Ct. 28, 29-30, 63 L.Ed. 1154 (1919), the right of peremptory challenge is nonetheless an important statutory right that courts have considered vital to an impartial jury trial.5 The Supreme Court has recognized the right of peremptory challenge as “essential ... to the impartiality of the trial[,]” Lewis, 146 U.S. at 378, 13 S.Ct. at 139 (citations omitted), and has noted that “[t]he persistence of peremptories and their extensive use demonstrate the long and widely held belief that peremptory challenge is a necessary part of trial by jury.” Swain, 380 U.S. at 219, 85 S.Ct. at 835. Indeed, in a recent decision, Justice Scalia, writing for the Court, suggested that the Sixth Amendment “requirement of an ‘impartial jury1 impliedly compels peremptory challenges[.]” Holland v. Illinois, 493 U.S. 474, 482, 110 S.Ct. 803, 808, 107 L.Ed.2d 905 (1990) (emphasis added).
In addition to allowing litigants to strike jurors in whom they perceive a bias, peremptory challenges also serve to reinforce challenges for cause. Peremptory challenges enhance the right to challenge jurors for cause because they allow litigants to strike prospective jurors who may have become antagonized by probing questions during voir dire. During voir dire, potential jurors are questioned about a wide range of subjects in an attempt to ferret out possible “causes” to challenge particular jurors. Despite admonitions to the contrary, vigorous questioning of potential jurors can foster hostility, since questions frequently require jurors to reveal deeply personal information in the presence of other potential jury members: marital *1138status, education, age, occupation, details about family members, financial information, involvement in past lawsuits, criminal records, “ ‘habits and associations^]’ ” Swain, 380 U.S. at 220, 85 S.Ct. at 836 (quoting Hayes v. State of Missouri, 120 U.S. 68, 70, 7 S.Ct. 350, 351, 30 L.Ed. 578 (1887)), personal opinions on a range of subjects, and other intimate details.6
The important interplay between challenges for cause and peremptory challenges has long been recognized. See Swain, 380 U.S. at 218-19, 85 S.Ct. at 835 (voir dire “tends to be extensive and probing[,]” and “operat[es] as a predicate for the exercise of peremptories[.]”). Blackstone was acutely aware of this dynamic, observing that “upon challenges for cause shown, if the reason assigned prove insufficient to set aside the juror, perhaps the bare questioning his indifference may sometimes provoke a resentment; to prevent all ill consequences from which, the prisoner is still at liberty, if he pleases, peremptorily to set him aside.” Blackstone, 4 Commentaries 353. As the Supreme Court has explained: “[T]he very availability of peremptories allows counsel to ascertain the possibility of bias through probing questions on the voir dire and facilitates the exercise of challenges for cause by removing the fear of incurring a juror’s hostility through examination and challenge for cause.” Swain, 380 U.S. at 219-20, 85 S.Ct. at 835 (emphasis added).
Although the two challenges work in tandem, peremptory challenges differ considerably from challenges for cause. Challenges for cause, while unlimited in number, allow the removal of panel members only “on a narrowly specified, provable, and legally cognizable basis of partiality,” id. at 220, 85 S.Ct. at 836, such as a personal relationship with a party, witness, or attorney in the litigation, or a biased state of mind concerning a party or issue in the case. The number of prospective jurors who may be excused for cause is unlimited. 28 U.S.C. § 1870. Challenges for cause require the challenging party to articulate clearly on the record the precise reason for challenging the potential juror, but the decision whether to exclude a panel member for cause is vested in the trial court. Gray v. Mississippi, 481 U.S. 648, 652 n. 3, 107 S.Ct. 2045, 2048 n. 3, 95 L.Ed.2d 622 (1987) (“[MJotion to excuse a venire member for cause ... must be supported by specified causes or reasons that demonstrate that, as a matter of law, the venire member is not qualified to serve.”).
Peremptory challenges, in contrast, are limited in number,7 and have traditionally been exercised according to the unfettered discretion of the litigant. A party seeking to exercise a peremptory challenge is generally not required to give a reason for its use, and may exercise peremptory challenges without judicial approval. Over a century ago, the Supreme Court characterized the peremptory challenge as “an arbitrary and capricious species of challenge to a certain number of jurors[,]” which may be made “without showing any cause at all.” Lewis, 146 U.S. at 376, 13 S.Ct. at 138 (citations omitted). More recently, the Court explained: “The essential nature of the peremptory challenge is that it is one exercised without a reason stated, without inquiry and without being subject to the court’s control.” Swain, 380 U.S. at 220, 85 S.Ct. at 836.8 The Supreme Court ex*1139plained the distinction between the two challenges in this fashion: “While challenges for cause permit rejection of jurors on a narrowly specified, provable and legally cognizable basis of partiality, the peremptory permits rejection for a real or imagined partiality that is less easily designated or demonstrable.” Id. at 220, 85 S.Ct. at 836 (citing Hayes, 120 U.S. at 68, 7 S.Ct. at 350) (emphasis added).
A litigant may perceive a “real or imaginary partiality” in a potential juror’s manner of response during voir dire, body language, or appearance, all of which might, in the eyes of a seasoned trial lawyer, reveal bias or hostility. Blackstone teaches that a peremptory challenge may be based on the mere “sudden impressions and unaccountable prejudices we are apt to conceive upon the bare looks and gestures of another,” and may be used to strike those “against whom he has conceived a prejudice, even without being able to assign a reason for such dislike.” Blackstone, 4 Commentaries 353.
B. Parameters of the right of peremptory challenge: procedural and substantive limitations
Despite the considerable freedom litigants have in exercising their right of peremptory challenge, the right is subject to procedures imposed by the trial court, and is circumscribed by an important substantive limitation: the anti-discrimination principle articulated by the Supreme Court in Batson v. Kentucky and cases following it.
1. Procedural limitations on peremptory challenges
A trial court has considerable discretionary control over the administration of peremptory challenges. First, trial courts have considerable control over the scope of questioning permitted during voir dire. Rosales-Lopez v. United States, 451 U.S. 182, 101 S.Ct. 1629, 68 L.Ed.2d 22 (1981) (applying an abuse of discretion standard to the trial judge’s decision whether to ask potential jurors about racial bias during voir dire). Second, trial courts exercise broad discretion in devising procedures by which parties exercise peremptory challenges. See, for example, United States v. Williams, 986 F.2d 86 (4th Cir.1993) (upholding “jury box” system of peremptory strikes), cert. denied, 509 U.S. 911, 113 S.Ct. 3013, 125 L.Ed.2d 703 (1993); United States v. Blouin, 666 F.2d 796 (2nd Cir.1981) (same). Finally, a trial court has considerable discretion in deciding whether to excuse a juror for cause, even where that decision necessitates that a litigant use a peremptory strike to remove a juror. Ross v. Oklahoma, 487 U.S. 81, 108 S.Ct. 2273, 101 L.Ed.2d 80 (1988).
Although a trial court has considerable discretionary authority in administering peremptory strikes, a trial court commits reversible error if its procedures effect an impairment or’ an outright denial of a party’s right of peremptory challenge. See, for example, Aldridge v. United States, 283 U.S. 308, 51 S.Ct. 470, 75 L.Ed. 1054 (1931) (reversal of criminal conviction required where trial court’s restrictions on questions posed during voir dire unreasonably infringed on defendant’s right to an impartial jury); Ham v. South Carolina, 409 U.S. 524, 93 S.Ct. 848, 35 L.Ed.2d 46 (1973) (reversible error where trial court refused to interrogate potential jurors as to possible racial prejudices); United States v. Turner, 558 F.2d 535 (9th Cir.1977) (reversible error for trial court to use a system of peremptory challenges under which defendant unwittingly “waived” the right to such challenges).
2. Substantive limitations on peremptory challenges
The seminal substantive limitation on the right of peremptory challenge emerged in Batson v. Kentucky, 476 U.S. 79, 106 S.Ct. 1712, 90 L.Ed.2d 69 (1986). There, the Supreme Court announced an important limitation: peremptory challenges may not be used in a racially discriminatory manner.
In enacting this important limiting principle, the Court in Batson explicitly overruled a portion of Swain v. Alabama, 380 U.S. 202, 85 S.Ct. 824, 13 L.Ed.2d 759 (1965). In Swain, the Court had allowed a prosecutor to use his peremptory challenges to remove all six black members of a jury panel in the criminal trial of a black defendant. The *1140Court acknowledged that the right of peremptory challenge is “frequently exercised on grounds normally thought irrelevant to legal proceedings or official'action, namely, the race, religion, nationality, occupation or affiliations of people summoned for jury duty.” Swain, 380 U.S. at 220, 85 S.Ct. at 836. Nonetheless, the Court refused to conclude that “the striking of Negroes in a particular case is a denial of equal protection of the laws.” Id. at 221, 85 S.Ct. at 836. Although it suggested that “a State’s systematic striking of Negroes in the selection of petit juries [might] raise[ ] a prima facie case under the Fourteenth Amendment,” it concluded that the record of strikes in a single case was “not sufficient to demonstrate” a violation of equal protection. Id. at 224, 85 S.Ct. at 838 (emphasis added).
Batson, however, reached the opposite conclusion. It held that where a prosecutor bases peremptory challenges on race, even in just one ease, those challenges constitute state action and violate the Fourteenth Amendment rights of both the prospective jurors and the criminal defendant. Batson therefore overruled only that portion of Swain defining the degree of proof needed to establish a violation of the Fourteenth Amendment right of equal protection.
Case law following Batson has delineated and refined the anti-discrimination limitation on the use of peremptory challenges. See Holland v. Illinois, 493 U.S. 474, 110 S.Ct. 803, 107 L.Ed.2d 905 (1990) (Caucasian defendant has standing to challenge discriminatory peremptory strikes against minority jury panel members); Edmonson v. Leesville Concrete Co., Inc., 500 U.S. 614, 111 S.Ct. 2077, 114 L.Ed.2d 660 (1991) (extending Bat-son principle to private litigants in civil actions); Georgia v. McCollum, 505 U.S. 42, 112 S.Ct. 2348, 120 L.Ed.2d 33 (1992) (defendant’s peremptory challenges subject to Bat-son principle); J.E.B. v. Alabama, 511 U.S. 127, 114 S.Ct. 1419, 128 L.Ed.2d 89 (1994) (extending the anti-discrimination principle to peremptory strikes based on gender).
In the wake of Batson, some commentators have called for the abolition of peremptory challenges altogether because they believe that such challenges are based solely on stereotypes and therefore serve to discriminate against various groups. See, for example, Jason Hochberg, “Peremptory Challenge: An American Relic,” 10 Crim.Just. 10 (1996); Christopher M. Ferdieo, “The Death of the Peremptory Challenge: J.E.B. v. Alabama,” 28 Creighton L.Rev. 1177 (1995); Susan A. Winehurch, Note, “J.E.B. v. Alabama ex rel T.B.: The Supreme Court Moves Closer to Elimination of the Peremptory Challenge,” 54 Md.L.Rev. 261 (1995); Raymond J. Broderick, “Why the Peremptory Challenge Should be Abolished,” 65 Temple L.Rev. 369 (1992); see also Batson v. Kentucky, 476 U.S. 79, 106 S.Ct. 1712, 90 L.Ed.2d 69 (1986) (Marshall, J., concurring).
The system of peremptory challenges has proved resilient, however, and remains a vital feature of the jury trial. Post-Batson decisions of the Supreme Court have reaffirmed the importance of peremptory challenges. In Holland v. Illinois, the Court explained:
We have acknowledged that that device [of peremptory challenge] occupies “an important position in our trial procedures,” Batson, 476 U.S. at 98 [106 S.Ct. at 1724], and has indeed been considered “a necessary part of trial by jury,” Swain v. Alabama, 380 U.S. at 219 [85 S.Ct. at 835]. Peremptory challenges, by enabling each side to exclude those jurors it believes will be most partial toward the other side, are a means of “eliminating] extremes of partiality on both sides,” ibid., thereby “assuring the selection of a qualified and unbiased jury,” Batson, 476 U.S. at 91, 106 S.Ct. at 1720. (emphasized in original)
493 U.S. at 484, 110 S.Ct. at 809.
■Federal judges, moreover, appear sanguine about peremptory challenges. A recent survey of federal district court judges indicates that a majority of judges viewed peremptory challenges “as a mechanism for attorneys to remove potential jurors biased in favor of the opposition^]” Christopher E. Smith & Roxanne Ochoa, “The Peremptory Challenge in the Eyes of the Trial Judge,” 79 Judicature 185, 186 (January-February 1996). More than 85 per cent of judges surveyed responded affirmatively when asked whether peremptory challenges “make *1141a beneficial contribution to the attainment of fair trials and just outcomes!.]” Id.
C. The traditional remedy for the deprivation of the right of peremptory challenge
Given the obvious importance of the right of peremptory challenge, a criminal defendant has long had a powerful remedy for the impairment or denial of this right: automatic reversal of the conviction. The Supreme Court has long maintained that “[t]he denial or impairment of the right is reversible error without a showing of prejudice.” Swain, 380 U.S. at 219, 85 S.Ct. at 835 (citations omitted). The Court has applied this remedy for over one hundred years. See Lewis, 146 U.S. 370, 376, 13 S.Ct. 136, 138, 36 L.Ed. 1011 (1892) (trial court’s deprivation of defendant’s peremptory challenges is reversible error); Harrison v. United States, 163 U.S. 140, 142, 16 S.Ct. 961, 961, 41 L.Ed. 104 (1896) (same); Gulf, Colorado & Santa Fe Ry. Co. v. Shane, 157 U.S. 348, 351, 15 S.Ct. 641, 642, 39 L.Ed. 727 (1895) (reversing adverse jury verdict where civil defendant deprived of right of peremptory challenge).
This Circuit has long followed this remedial principle. In United States v. Turner, we held that “[a]n error in restricting the exercise of peremptory challenges results in an automatic reversal. The defendant need not show that he was prejudiced by the error.” United States v. Turner, 558 F.2d 535, 538 (9th Cir.1977). In Turner, the district court restricted a criminal defendant’s exercise of peremptory challenges by treating his attorney’s unwitting failure to challenge a co-defendant’s jury panel as a waiver of Turner’s right of peremptory challenge. Turner was thereafter convicted of a series of offenses growing out of his assault on a fellow federal prisoner. On appeal, we concluded that the effect of the district court’s procedure was to deprive Turner of all of his peremptory challenges. For that reason, we reversed his conviction. See also Medrano v. City of Los Angeles, 973 F.2d 1499, 1503 (9th Cir.1992) (reversible error where trial court erroneously denied peremptory challenge to alternate juror who ultimately replaced member of jury and rendered verdict), cert. denied, 508 U.S. 940, 113 S.Ct. 2415, 124 L.Ed.2d 638 (1993); United States v. Brooklier, 685 F.2d 1208, 1223 (9th Cir.1982) (“The defendant need not show actual prejudice. Any error which impairs the exercise of peremptory challenges is reversible error.”) (citing Swain and Turner), cert. denied, 459 U.S. 1206, 103 S.Ct. 1194, 1195, 75 L.Ed.2d 439 (1983); United States v. Allsup, 566 F.2d 68, 71 (9th Cir.1977) (same).
Moreover, every other circuit to address this issue agrees that the erroneous deprivation of a defendant’s right of peremptory challenge requires automatic reversal. See United States v. Broussard, 987 F.2d 215, 221 (5th Cir.1993) (“The denial or impairment of the right to exercise peremptory challenges is reversible error without a showing of prejudice.”), abrogated on other grounds by J.E.B. v. Alabama, 511 U.S. 127, 114 S.Ct. 1419, 128 L.Ed.2d 89 (1994); Olympia Hotels Corp. v. Johnson Wax Dev. Corp., 908 F.2d 1363, 1369 (7th Cir.1990) (“It is reversible error to deny a party to a jury trial the peremptory challenges to which the rules of procedure entitle him....”); United States v. Ruuska, 883 F.2d 262, 268 (3rd Cir.1989) (affirming the automatic reversal rule described in Swain, and stating that Batson “does not call into question this aspect of Swain.”); United States v. Ricks, 802 F.2d 731, 734 (4th Cir.) (en banc), cert. denied, 479 U.S. 1009, 107 S.Ct. 650, 93 L.Ed.2d 705 (1986) (same); Carr v. Watts, 597 F.2d 830, 832 (2nd Cir.1979) (impairment of right of peremptory challenge is “reversible error without a showing of prejudice”). Other circuits have recognized the automatic reversal rule in dicta. See United States v. Cambara, 902 F.2d 144, 147 (1st Cir.1990) (“restricting a defendant’s use of the lawful number of peremptory challenges is reversible error if a challenge for cause is erroneously denied”); United States v. Mosely, 810 F.2d 93, 96 (6th Cir.), cert. denied, 484 U.S. 841, 108 S.Ct. 129, 98 L.Ed.2d 87 (1987) (same).
With this understanding of peremptory challenges in mind, we turn next to the proper remedy to be applied once an erroneous *1142deprivation of the right of peremptory challenge is found.
II. The appropriateness of the traditional remedy in light of recent developments in criminal procedure
The government relies upon two divergent strains of case law to overcome the longstanding remedy of automatic reversal: (1) the emergence of the anti-discrimination principle in Batson and its progeny and (2) the evolution of harmless-error analysis. We now consider these disparate legal developments and whether either of these changes supports a harmless-error rule announced by the panel.
A. Batson and the rule of automatic reversal
The government’s first argument — that Batson and subsequent cases have effectively eroded the right of peremptory challenge — is misplaced. First, Batson and its progeny merely limited the right of peremptory challenge; the Supreme Court has never announced an intention to abolish it. Although the cases prohibit peremptory challenges that effect discrimination on the basis of race or gender, the anti-discrimination principle they articulated is not a wholesale rejection of the peremptory challenge as an important tool in jury selection. As discussed above, the peremptory challenge serves a broader purpose: to enable litigants to strike jurors who appear biased in some other respect, or those who exhibit hostility toward a particular litigant or attorney. The broader rationale for peremptory challenges thus survives the Batson line of decisions. Indeed, post-jBatson decisions by the Supreme Court confirm the continuing viability and importance of peremptory challenges as a means of achieving an impartial jury. In Holland, for example, the Court noted that “the system of peremptory challenges has traditionally provided” an “assurance of impartiality.” Holland, 493 U.S. at 483, 110 S.Ct. at 809. Second, our review of the reasoning of Bat-son and later cases convinces us that these eases in no way undermine the justifications for the right of peremptory challenge. The equal protection rationale of Batson and later eases simply has no bearing on peremptory challenges that are not based on invidious group discrimination.
The government’s second concern — that a rule of automatic reversal punishes district courts that are overzealous in enforcing the anti-discrimination principle of Batson and its progeny — is also unfounded. It is true that trial courts bear a heavy burden in enforcing Batson’s anti-discrimination principle, given that the erroneous denial of a party’s peremptory challenge has traditionally warranted automatic reversal. However, this concern was alleviated by a recent Supreme Court decision offering guidance to trial courts faced with deciding whether a particular peremptory challenge has a discriminatory motive. In Purkett v. Elem, the Court clarified the burden imposed on the party proposing a peremptory challenge. Once the opponent of a peremptory challenge has made out a prima facie ease of racial discrimination pursuant to Batson, the burden shifts to the proponent of the strike “to come forward with a race-neutral explanation.” Purkett, - U.S. at -, 115 S.Ct. at 1770. The standard announced by the Supreme Court in Purkett is a forgiving one: the proponent’s burden of production “does not demand an explanation that is persuasive, or even plausible. ‘At this step of the inquiry, the issue is the facial validity of the [ ] explanation. Unless a discriminatory intent is inherent in the [] explanation, the reason offered will be deemed race neutral.’ ” Purkett, - U.S. at -, 115 S.Ct. at 1771 (citing Hernandez v. New York, 500 U.S. 352, 360, 111 S.Ct. 1859, 1866-67, 114 L.Ed.2d 395 (1991)).
Given Purkett’s lenient standard, which leaves vast room for discretion on the part of trial courts ruling on Batson objections, the government’s second concern is misplaced. Purkett clarifies the distinction between proper peremptory challenges and improper, race- or gender-based challenges. The threat of reversal therefore need not hamstring the trial courts in allowing peremptory challenges.
Finally, we address what is perhaps the central consideration in deciding whether Batson and its progeny justify supplanting *1143our traditional automatic reversal rule: whether and how the Batson line of cases bear on the remedy for the erroneous deprivation of a right of peremptory challenge. At the very heart of this case is this question: what is the proper remedy for the deprivation of a right of peremptory challenge? Significantly, Batson never addressed this issue. For that reason, Batson left intact that portion of Swain that set forth the remedial rule for such errors: “The denial or impairment of the right [of peremptory challenge] is reversible error without a showing of prejudice.” Swain, 380 U.S. at 218, 85 S.Ct. at 835 (citations omitted). Any other conclusion simply misapprehends the analysis in Bat-son.
Given the foregoing analysis, we conclude that Batson and subsequent cases do not support the adoption of a harmless-error standard for the erroneous deprivation of the right of peremptory challenge. These cases neither eliminate the right of peremptory challenge nor weaken its remedy of automatic reversal.
B. Applicability of harmless-error analysis to the erroneous denial of the right of peremptory challenge
We turn next to the government’s second suggested rationale for substituting a harmless-error analysis for the longstanding rule of automatic reversal. The government contends that apart from cases where the evidence does not justify conviction beyond a reasonable doubt, “the only cases where reversal is mandatory are those in which structural error occurred[.]” Response to Petition for Rehearing at 3, citing Annigoni, 68 F.3d at 284 (citing Brecht v. Abrahamson, 507 U.S. 619, 628-30, 113 S.Ct. 1710, 1717, 123 L.Ed.2d 353 (1993)). The government also relies on the Supreme Court’s decision in Ross v. Oklahoma, which applied a harmless-error analysis to a trial court’s erroneous denial of a challenge for cause, an error the defendant claimed forced him to waste a peremptory challenge. Although neither of these decisions require a departure from the rule of automatic reversal, the government argues, based on these sources, that the erroneous denial of peremptory challenge is subject to harmless-error analysis. We strongly disagree.
1. Harmless-error analysis
Under harmless-error analysis, an appellate court, upon finding that either a constitutional or non-constitutional error occurred in the trial court, may nonetheless affirm a conviction on the ground that the error was harmless. Federal Rule of Criminal Procedure 52(a) provides that “any error, defect, irregularity or variance which does not affect substantial rights shall be disregarded.” The purpose of harmless-error analysis is to avoid “setting aside convictions for small errors or defects that have little, if any, likelihood of having changed the result of the trial,” because reversal would entail substantial social costs. Chapman v. California, 386 U.S. 18, 22, 87 S.Ct. 824, 827, 17 L.Ed.2d 705 (1967) (emphasis added).
In determining whether an error is subject to harmless-error analysis, a reviewing court must determine whether the error is a “classic ‘trial error,’ ” such as the improper admission of evidence. Arizona v. Fulminante, 499 U.S. 279, 309, 111 S.Ct. 1246, 1264, 113 L.Ed.2d 302 (1991). In Fulminante, the Supreme Court defined “trial error” as “error which occurred during the presentation of the case to the jury, and which may therefore be quantitatively assessed in the context of other evidence presented in order to determine whether its admission was harmless beyond a reasonable doubt.” Fulminante, 499 U.S. at 307-08, 111 S.Ct. at 1264 (emphasis added). “Structural” errors, in contrast, are “defects in the constitution of the trial mechanism, which defy analysis by ‘harmless-error’ standards [,]” id. at 309, 111 S.Ct. at 1265 (emphasis added), and affect “the framework within which the trial proceeds, rather than simply an error in the trial process itself.” Id. at 310, 111 S.Ct. at 1265.
Some commentators have treated harmless-error jurisprudence as establishing a strict dichotomy between trial error, which is subject to harmless-error analysis, and structural error, which is per se reversible. See “Twenty-Fourth Annual Review of Criminal Procedure,” 83 Georgetown L.J. 665, 1365 *1144(March-April 1995). The case law does not appear to establish such a rigid dichotomy, however. In its recent Brecht decision, the Supreme Court characterized the divergence between trial and structural errors as a “spectrum of constitutional errors” rather than a rigid dichotomy. Brecht, 507 U.S. at 629, 113 S.Ct. at 1717 (emphasis added). See also Fulminante, 499 U.S. at 290-91, 111 S.Ct. at 1254-55 (White, J., dissenting) (“our jurisprudence on harmless error has not classified so neatly the errors at issue” so as to establish a “meaningless dichotomy between ‘trial errors’ and ‘structural defects.’ ”).. Moreover, numerous errors are subject to automatic reversal even though they do not violate constitutional rights, Gomez v. United States, 490 U.S. 858, 874-76, 109 S.Ct. 2237, 2248, 104 L.Ed.2d 923 (1989) (reversible error for magistrate to supervise voir dire during felony trial in violation of Federal Magistrate’s Act, which violated defendant’s statutory right “to have all critical stages of a criminal trial conducted by a person with jurisdiction to preside.”), or fit the definition of structural error. United States v. Pelletier, 898 F.2d 297, 303 (2nd Cir.1990) (deliberate use at trial of defendant’s immunized grand jury testimony cannot be considered harmless error). Although we conclude that the erroneous denial of the right of peremptory challenge is not amenable to harmless-error analysis, we need not decide whether such error rises to the level of structural error.
The error in this case — the erroneous denial of a right of peremptory challenge — is simply not amenable to harmless-error analysis. First, unlike typical trial errors, this error did not “occur[] during the presentation of the case to the jury[J” Fulminante, 499 U.S. at 307, 111 S.Ct. at 1264. Instead, the initial denial of the challenge occurred before the presentation of the ease, but the resulting presence of Juror Horn was an ongoing feature of the trial.
Second, this error, unlike the error in Ful-minante, may not be “quantitatively assessed in the context of other evidence presented in order to determine whether its admission was harmless beyond a reasonable doubt.” Id. at 308, 111 S.Ct. at 1264. (emphasis added). In Fulminante, the Court held that the admission of a defendant’s coerced confession was subject to harmless-error analysis. Fulminante, 499 U.S. at 295, 111 S.Ct. at 1257. In its harmless-error analysis; the Court looked at the erroneously admitted evidence and compared it to other evidence the government had mustered against the defendant. It was able to evaluate the impact of the error because it was able to weigh the coerced confession relative to other known and tangible evidence. It also had an entire trial record as a frame of reference against which to compare the erroneously admitted confession. Given all of the information it had, and given its institutional ability to weigh such evidence, the Court in Fulminante had a rational basis on which to assess the particular harm and to conclude that the erroneous admission of the coerced confession was not harmless.
Unlike errors the Supreme Court has subjected to harmless-error analysis, it would be virtually impossible to determine whether the denial of a peremptory challenge was harmless enough to warrant affirming the conviction. For several reasons, the denial of a defendant’s right of peremptory challenge eludes a determination of whether a judgment was or was not “substantially swayed by the error.”9
To apply a harmless-error analysis in this context would be to misapprehend the very nature of peremptory challenges. The peremptory challenge is used precisely when there is no identifiable basis on which to challenge a particular juror for cause. By its very nature, the peremptory challenge is a tool that may be wielded in a highly subjective and seemingly arbitrary fashion, based upon mere impressions and hunches. Although a litigant may suspect that a potential juror harbors an unarticulated bias or hostility, that litigant would be unable to demonstrate that bias or hostility to an appellate *1145court reviewing for harmless error. Similarly, the government would be hard-pressed to bear its burden of proving that the seating of a peremptorily challenged juror did not harm the defendant. United States v. Olano, 507 U.S. 725, 734, 113 S.Ct. 1770, 1777-78, 123 L.Ed.2d 508 (1993) (under harmless error review, government bears the burden of persuasion with respect to prejudice). It would be difficult if not impossible for a reviewing court to determine the degree of harm resulting from erroneously allowing a juror to sit despite an attempted peremptory challenge.
Another obstacle to harmless-error review of an erroneous denial of peremptory challenge is the dearth of information concerning what went on in the jury room. To subject the denial of a peremptory challenge to harmless-error analysis would require appellate courts to do the impossible: to reconstruct what went on in jury deliberations through nothing more than post-trial hearings and sheer speculation. In the context of an appeal based on denial of a peremptory challenge, there is inadequate evidence for an appellate court to determine the degree of harm resulting from the seating of a juror despite a defendant’s attempted peremptory strike. See also United States v. Noushfar, 78 F.3d 1442, 1445-46 (9th Cir.1996) (holding that it was structural error for district court to allow jury to listen to audio tapes that had not been played during the trial, and emphasizing that reviewing court “cannot assess the impact” on the jury’s deliberations); Guam v. Marquez, 963 F.2d 1311, 1316 (9th Cir.1992) (holding that it was structural error for trial court to give written instructions to jury in lieu of reading them in open court, and explaining that the error “prevents an appellate court from conducting a harmless error analysis because the record is silent regarding whether any of the jurors read the instructions,” making it “impossible to determine if [the] error was prejudicial.”).
The facts of this case illustrate the practical problems with applying a harmless-error analysis to a trial court’s erroneous denial of a peremptory challenge. The transcript of voir dire contains very little detail about Juror Horn and the extent of any biases he might have had against, for example, limited partnerships, real estate brokers, or Annigo-ni himself. On this typically sparse record, there is simply no way to tell whether the seating of Juror Horn was harmless, or highly prejudicial, much less any way to ascertain Juror Horn’s impact, if any, on the jury’s verdict against Annigoni.
Under harmless-error review, it is the government that “bears the burden of persuasion with respect to prejudice.” Olano, 507 U.S. at 734, 113 S.Ct. at 1778. It is far from certain that this error was harmless here. Juror Horn took his place on the jury, over appellant’s wishes, because the district court erroneously refused to allow appellant to exercise a peremptory strike against him. To apply a harmless-error analysis omits an important consideration: the potential harm of having Juror Horn sit in judgment of the appellant. In this ease, Annigoni’s attorney sought to excuse potential juror Jue Horn because she was concerned that his investments in Merrill Lynch limited partnerships and his possible involvement in litigation concerning those investments suggested he would be more inclined to convict Annigoni for his involvement in an allegedly fraudulent limited partnership. Such concerns appear well-founded. In recent years, numerous investors have filed class-action lawsuits over sales of risky limited partnerships, and Merrill Lynch is one of several major brokerage houses defending such suits.10 That Juror Horn was not challengeable for cause is irrelevant, since the harm alleged was denial of a peremptory strike, not denial of a challenge for cause. Based on Juror Horn’s investment experience, one could plausibly infer that he might bear hostility toward purveyors of lim*1146ited partnerships who undertake fraudulent transactions. The attempted application of harmless-error analysis in this ease demonstrates the futility of evaluating the harm that flows from the denial of a defendant’s right of peremptory challenge.
2. The harmless-error rule of Ross v. Oklahoma
The final legal authority on which the government relies in seeking a new remedy for erroneous deprivations of peremptory challenges is Ross v. Oklahoma, 487 U.S. 81, 108 S.Ct. 2273, 101 L.Ed.2d 80 (1988). In Ross, a state trial court erroneously denied a defendant’s challenge for cause. To counteract this error, the defendant used a peremptory challenge to strike the challenged juror. Although Ross argued that the trial court’s error violated his Sixth and Fourteenth Amendment right to an impartial jury and his Fourteenth Amendment right to due process by requiring him to use a peremptory challenge he otherwise would not have needed to use, the Supreme Court did not reverse Ross’s conviction. It reasoned, first, that the right of peremptory challenge is not constitutional, Ross, 487 U.S. at 88, 108 S.Ct. at 2278, and, second, that Ross received and used all the peremptory challenges to which Oklahoma law entitled him, concluding that “the ‘right’ to peremptory challenges is ‘denied or impaired’ only if the defendant does not receive that which state law provides.” Id. at 89, 108 S.Ct. at 2279. Unlike Annigoni, Ross did receive the peremptories to which he was entitled under state law, and exercised them to remove the suspicious juror. As a consequence, the offending juror did not sit on the jury that convicted him. Ross, 487 at 85-86, 108 S.Ct. at 2276-77.
Because Ross did not involve the erroneous denial of a peremptory challenge, its holding does not support the conclusion that the error in this case — the outright denial of a peremptory challenge — warrants mere harmless-error review. The government unfortunately offers little analysis of how Ross supports the adoption of a harmless error remedy. Instead, it miseharaeterizes Ross as having involved the loss of a peremptory challenge, then suggests that because the verdict against Ross was not reversed, Anni-goni’s conviction should also stand. The government’s reading of Ross, however, ignores key differences between Ross and this case, differences which warrant different remedies.
The Court in Ross did not outright block the defendant’s peremptory challenge on the basis of a Batson objection, as did the district court in this case. Rather, the court’s erroneous denial of Ross’s challenge for cause prompted Ross to expend one of his peremptory challenges to remove the questionable juror; it never deprived him of the right of peremptory challenge. Even more significantly, the juror in Ross never sat on the jury that convicted Ross. The case therefore does not present the problem posed by harmless-error analysis in this ease: the impossibility of ascertaining Juror Horn’s impact on the outcome.
These two distinctions suggest that reliance on Ross is misplaced. This conclusion is bolstered not only by the reasoning of Ross itself, but also by decisions subsequent to Ross wherein courts continue to reverse convictions where trial courts have impaired a litigant’s right of peremptory challenge.
First, the Supreme Court in Ross distinguished the outright denial of a peremptory challenge from the forced use of a peremptory challenge. The Ross court itself acknowledged that “the right to exercise peremptory challenges is ‘one of the most important of the rights secured to the accused,”’ Ross, 487 U.S. at 89, 108 S.Ct. at 2278, citing Swain, 380 U.S. at 219, 85 S.Ct. at 835, and acknowledged the rule in Swain that “ ‘[t]he denial or impairment of the right is reversible error without a showing of prejudice.’ ” Ross, 487 U.S. at 89, 108 S.Ct. at 2279, citing Swain, 380 U.S. at 219, 85 S.Ct. at 835. Without questioning the automatic reversal rule, the Court in Ross first rejected Ross’s due process claim because it noted that peremptory challenges are guaranteed by statute, not by the Constitution. Ross, 487 U.S. at 89, 108 S.Ct. at 2278-79. Second, the Court explained that in state cases, state law governs the number, purpose, and manner of peremptory challenges. Noting that Ross was not deprived of his state-law protections, *1147the Court concluded that there had been no violation of the state-law right of peremptory challenge. Id. Annigoni, in contrast, was wrongly denied his right of peremptory strike against Juror Horn.
More recently, other circuits have distinguished the application of harmless error in Ross from the outright denial of peremptory challenges. See Kirk v. Raymark Industries, Inc., 61 F.3d 147 (3rd Cir.1995) (holding that the denial or impairment of a statutory right of peremptory challenge is per se reversible without proof of prejudice, and distinguishing the claim in Ross as constitutionally based), cert. denied, - U.S. -, 116 S.Ct. 1015, 134 L.Ed.2d 95 (1996); United States v. Broussard, 987 F.2d 215, 221 (5th Cir.1993) (holding that the denial of right of peremptory challenge is reversible error even after Ross, and explaining that applying harmless-error review to the erroneous denial of a peremptory challenge “would eviscerate the right to exercise peremptory challenges, because it would be virtually impossible to determine that [the denial], injurious to the perceived fairness of the petit jury [was] harmless.”), abrogated on other grounds by J.E.B. v. Alabama, 511 U.S. 127, 114 S.Ct. 1419, 128 L.Ed.2d 89 (1994). These decisions demonstrate the continued viability of the automatic reversal rule after Ross.
3. The distinction between the misuse of a peremptory challenge and the denial of a peremptory challenge
Finally, we consider the distinction the government would have us draw between the erroneous use of a peremptory challenge and the erroneous denial of its use. Clearly, the proper remedy for the improper use of a peremptory challenge is automatic reversal. But this does not mean it would be appropriate to subject the denial of a peremptory challenge to mere harmless-error review. If the former were reversible error but the latter were subject to harmless-error review, a district court would have every incentive to err on the side of denying peremptory challenges. Such a disparity in remedies would seriously impair the full use of peremptory challenges, because it would encourage a district court to deny peremptory challenges in close cases.
CONCLUSION
For the reasons discussed above, we hold that the denial of a peremptory challenge was erroneous, and the error requires reversal of the conviction.
REVERSED and REMANDED.
. Batson v. Kentucky, 476 U.S. 79, 106 S.Ct. 1712, 90 L.Ed.2d 69 (1986).
. Batson and its progeny require a three-step process for challenging a peremptory strike: (1) The party opposing the peremptory strike must make a prima facie showing that the proposed peremptory strike is racially discriminatory, taking account of "all the relevant circumstances!?]" (2) The burden then shifts to the proponent of the strike to come forward with a race-neutral explanation for the strike. (3) Finally, if a race-neutral explanation is tendered, the trial court must decide whether the party opposing the strike has proved purposeful racial discrimination. Batson, 476 U.S. at 96-98, 106 S.Ct. at 1722-24; See also Hernandez v. New York, 500 U.S. 352, 358-59, 111 S.Ct. 1859, 1865-66, 114 L.Ed.2d 395 (1991) (explaining the three-step Batson analysis); Purkett v. Elem, - U.S. -, - - -, 115 S.Ct. 1769, 1770-71, 131 L.Ed.2d 834 (1995) (same).
. We review for clear error a district court's findings of fact as to the racially discriminatory use of peremptory challenges. United States v. De Gross, 960 F.2d 1433, 1442 (9th Cir.1992) (en banc).
. Although we decide this case in the context of the rights of a defendant, the peremptory challenge is an equally important tool to insure that the government receives a fair trial. Purkett v. Elem, - U.S. -, -, 115 S.Ct. 1769, 1771, 131 L.Ed.2d 834 (1995) (upholding prosecutor's use of peremptory strike).
. Although the right of peremptory challenge does not derive from the Constitution, it nonetheless is a “venerable” tradition dating back centuries. Holland v. Illinois, 493 U.S. 474, 480, 110 S.Ct. 803, 807, 107 L.Ed.2d 905 (1990). As described in Lewis, “[t]he right of challenge comes from the common law with the trial by jury itself, and has always been held essential to the fairness of trial by jury.” Lewis, 146 U.S. at 376, 13 S.Ct. at 138. The right of peremptory challenge has "very old credentials^]” Swain, 380 U.S. at 212, 85 S.Ct. at 831. At common law, the defendant in a felony trial was allowed a certain number of peremptory challenges; by the seventeenth century, prosecutors, too, were allowed to remove potential jurors peremptorily. Swain, 380 U.S. at 213, 85 S.Ct. at 832 (citing The Ordinance for Inquests, 33 Edw. 1, Stat. 4 (1305)). Shortly after the founding of the United States, an early Congress codified the English common law of peremptory challenges in a 1790 statute. Holland, 493 U.S. at 481, 110 S.Ct. at 807-08 (citing Act of Apr. 30, 1790, ch. 9, § 30, 1 Stat. 112, 119 (1790)) (granting defendants 20 peremptory challenges in felony trials). Several states patterned peremptory challenge statutes after the federal model. Swain, 380 U.S. at 215-16, 85 S.Ct. at 833-34. Today, the right of peremptory challenges in federal criminal trials is guaranteed by Federal Rule of Criminal Procedure 24(b).
. Although the potential for juror hostility is greater where counsel conducts or participates in voir dire, it is also present where the trial court alone conducts the inquiry.
. Federal Rule of Criminal Procedure 24(b) provides the following peremptory challenges: In capital cases, both the government and the defendant are entitled to twenty peremptory challenges. In felony cases, the defendant is allowed ten peremptory challenges while the government is allowed six. Finally, in misdemeanor cases, each side is allowed three peremptory challenges.
. As discussed below, the sole restriction on the use of peremptory challenges is that neither side may exercise a challenge on the basis of the race, gender, or ethnicity of the challenged juror. See Batson v. Kentucky, 476 U.S. 79, 106 S.Ct. 1712, 90 L.Ed.2d 69 (1986); J.E.B. v. Alabama, 511 U.S. 127, 114 S.Ct. 1419, 128 L.Ed.2d 89 (1994); Hernandez v. New York, 500 U.S. 352, 111 S.Ct. 1859, 114 L.Ed.2d 395 (1991). The trial court must determine whether a proposed challenge violates the precept of Batson, but the challenging party need only offer a cursory explanation to survive a Batson objection. Purkett v. Elem, - U.S. -, 115 S.Ct. 1769, 131 L.Ed.2d 834 (1995).
. Where, as here, the error was not constitutional, the Supreme Court requires that to uphold a conviction, federal appellate courts applying harmless-error analysis must determine with “fair assurance ... that the judgment was not substantially swayed by the error." Kotteakos v. United States, 328 U.S. 750, 765, 66 S.Ct. 1239, 1248, 90 L.Ed. 1557 (1946)(emphasis added).
