What is the legal test for making a peremptory challenge based on race?

"The Batson three-step inquiry is well established. First, the trial court must determine whether the defendant has made a prima facie showing that the prosecutor exercised a peremptory challenge based on race. Second, if the showing is made, the burden shifts to the prosecutor to demonstrate that the challenges were exercised for a race-neutral reason. Third, the court determines whether the defendant has proven purposeful discrimination. The ultimate burden of persuasion regarding racial motivation rests with, and never shifts from, the opponent of the strike. [Citation.] The three-step procedure also applies to state constitutional claims." (People v. Lenix, supra, 44 Cal.4th at pp. 612-613; People v. Gutierrez, supra, 2 Cal.5th at p. 1158.)

To make a prima facie showing of impermissible discrimination, a defendant must produce "evidence ' "sufficient to permit the trial judge to draw an inference that discrimination has occurred." ' " (People v. Jones, supra, 57 Cal.4th at p. 916.) Once a prima facie case of group bias appears, the prosecution must demonstrate a proper basis for the allegedly offending challenge, and the court must "satisfy itself that the explanation is genuine. This demands of the trial judge a sincere and reasoned attempt to evaluate the prosecutor's explanation in light of the circumstances of the case as then known, his knowledge of trial techniques, and his observations of the manner in which the prosecutor has examined members of the venire and has exercised challenges for cause or peremptorily, for 'we rely on the good judgment of the trial courts to distinguish bona fide reasons for such peremptories from sham excuses belatedly contrived to avoid admitting acts of group discrimination.'
