In what circumstances have the courts found that the defense made a prima facie showing as to each of the prosecutor's challenges?

In both trials, the trial court found that the defense made a prima facie showing as to each of the prosecutor's challenges and required the prosecutor to articulate reasons for them. The court then found each challenge was justified with a nondiscriminatory reason. Defendants' contentions relate to the third-stage inquiry to determine whether defendants proved purposeful discrimination. (See People v. Silva, supra, 25 Cal.4th at p. 384; Purkett v. Elem, supra, 514 U.S. at p. 767.)
