Opinion of the Court by Kruger, J.

For nearly half a century, our law has steadfastly prohibited discrimination on the basis of race or other protected status in selecting juries. (People v. Wheeler (1978) 22 Cal.3d 258, 273 (Wheeler); Batson v. Kentucky (1986) 476 U.S. 79, 91 (Batson).) The reason for this prohibition is as familiar as it is vital to the operation of a system that guarantees equal treatment to all. As our cases have repeatedly and consistently recognized, discrimination in jury selection harms not only litigants and persons called to jury service, but the very integrity of our system of justice. To enforce the prohibition, the courts in Wheeler and Batson set forth a procedural framework for determining whether a litigant’s decision to peremptorily challenge a prospective juror was motivated by improper bias. After years of experience applying this framework, commentators increasingly came to question whether the framework is adequate to identify and curb improper discrimination when it occurs. In response to these concerns, the Legislature enacted Code of Civil Procedure section 231.7, which establishes a new framework for evaluating discrimination-related objections to peremptory challenges. Under the statute, if an objection is made to a peremptory challenge, the striking party must give its reasons for exercising the peremptory challenge. (Code Civ. Proc., § 231.7, subds. (b), (c) (section 231.7).) If, after considering the striking party’s reasons, a “court determines

1 PEOPLE v. SANMIGUEL Opinion of the Court by Kruger, J.

there is a substantial likelihood that an objectively reasonable person would view race, ethnicity, gender, gender identity, sexual orientation, national origin, or religious affiliation, or perceived membership in any of those groups, as a factor in the use of the peremptory challenge, then the objection shall be sustained.” (§ 231.7, subd. (d)(1) (section 231.7(d)(1).) This case concerns the provisions of section 231.7 addressing a situation in which the striking party gives reasons relating to the prospective juror’s demeanor, behavior, or manner of responding to questions (collectively referred to as behavior-based reasons). Under the statute, these reasons “are presumptively invalid unless the trial court is able to confirm that the asserted behavior occurred . . . . Even with that confirmation, the counsel offering the reason shall explain why the asserted demeanor, behavior, or manner in which the prospective juror answered questions matters to the case to be tried.” (§ 231.7, subd. (g)(2) (section 231.7(g)(2).) Here, a prosecutor listed multiple reasons for striking a prospective juror, including a behavior-based reason: that the prospective juror was not as engaged and was less attentive than other prospective jurors. The trial court confirmed the prosecutor’s observations and overruled the defense’s section 231.7 objection without insisting on a further explanation of why these behaviors “matter[] to the case to be tried.” (§ 231.7(g)(2).) The Court of Appeal affirmed. It concluded that, notwithstanding the absence of such explanation, the prosecutor’s and court’s observations about the prospective juror’s attentiveness were not only sufficient to overcome the statutory presumption that the behavior-based reason was invalid, but also independently sufficient to establish the lawfulness of the strike.

2 PEOPLE v. SANMIGUEL Opinion of the Court by Kruger, J.

The Court of Appeal’s resolution of the issue reveals a number of points of uncertainty in the developing law of section 231.7. We now clarify two general principles about behavior-based reasons under section 231.7, subdivision (g). First, to overcome the presumption that a behavior-based reason is invalid, the striking party must offer an explanation that is sufficient to allow the court to evaluate the reason as part of its overarching determination of whether an objective observer would view race or other protected status as a factor in the exercise of the peremptory challenge. A court may be able to confirm, for instance, that a prospective juror is not making eye contact. But it cannot adequately evaluate the striking party’s motivation unless the striking party tells the court what it is inferring from the behavior about how the prospective juror would perform the duties of a juror — as the statute puts it, why the lack of eye contact “matters to the case to be tried.” (§ 231.7(g)(2).) Ultimately, the explanation requirement is a functional one, and the statute does not prescribe a rigid sequence of steps or a particular verbal formula that must be employed to satisfy it. Second, whether a behavior-based reason is found to be valid or invalid is not dispositive of the ultimate inquiry into the presence of unlawful discrimination. If the reason is invalid, it may not be relied on to justify the strike. While reliance on an invalid reason is generally a significant consideration — and, depending on the circumstances, may prove dispositive — a court still must consider any other reasons proffered and other relevant circumstances to determine whether the strike was unlawful under section 231.7. Conversely, finding that the statutory presumption of invalidity has been overcome is not necessarily dispositive of the lawfulness of the strike. A court

may conclude that a behavior-based reason is valid and yet determine, after weighing other reasons and relevant circumstances, that an objective observer would still likely conclude that race or other protected status was a factor in the peremptory challenge. Because the Court of Appeal in this case did not apply these principles in evaluating the section 231.7 challenge, we reverse and remand for further proceedings. I. A. Because this is our first case interpreting section 231.7, we begin by reviewing the relevant legal background in some detail. In selecting a jury, litigants may raise two types of challenges to prospective jurors: for cause and peremptory. (Wheeler, supra, 22 Cal.3d at p. 273; Code Civ. Proc., § 225, subd. (b).) For-cause challenges are limited to concerns about prospective juror qualifications and actual or implied bias. (Code Civ. Proc., § 225, subd. (b)(1) [permitting “[a] challenge for cause” for “[g]eneral disqualification,” “[i]mplied bias,” or “[a]ctual bias”]; see id., § 228 [defining “general disqualification”].) Peremptory challenges, in contrast, were “designed to be used ‘for any reason, or no reason at all.’ ” (People v. Scott (2015) 61 Cal.4th 363, 387 (Scott).) Peremptory challenges are not constitutionally required, but they “traditionally have been viewed as one means of assuring the selection of a qualified and unbiased jury.” (Batson, supra, 476 U.S. at p. 91.) The idea is that peremptory challenges “allow[] removal of a biased juror” when “the party either cannot establish his reason by normal methods of proof or cannot do so without causing embarrassment to the challenged venireman

and resentment among the remaining jurors.” (Wheeler at p.
