them for either refusing to assist Belaire-West or for assisting Plaintiffs and, finally, accurately sets forth the contentions of the parties.”
The court continued, “Having considered the parties’ respective contentions, the contents of the proposed notice and having balanced the potential for abuse against Plaintiffs’ rights fully to investigate their claims and the rights of privacy of the potential class members, the court is satisfied that the form of notice to be sent to the putative class members insures and effectively limits the potential for any abuse.”
Belaire-West filed the instant petition for writ of mandate and sought an immediate stay. This court ordered the requested stay and issued an order to show cause why the order adopting the opt-out notice should not be rejected in favor of an opt-in privacy notice procedure. The parties submitted briefing on this issue and then, at this court’s request, submitted supplemental briefs addressing the impact of the California Supreme Court’s recent decision in Pioneer, supra, 40 Cal.4th 360.
DISCUSSION
In Pioneer, supra, 40 Cal.4th 360, the California Supreme Court addressed the question of whether to use an opt-out or opt-in notice for precertification discovery of potential class members in a putative class action suit. The potential class members in Pioneer were individuals who had complained to Pioneer that its DVD players were defective. The California Supreme Court concluded that under the circumstances presented, an opt-out notice was sufficient to protect the privacy rights of the DVD purchasers. (Pioneer, supra, 40 Cal.4th at p. 366.)
The Supreme Court began with an analysis of the right to privacy, which “protects the individual’s reasonable expectation of privacy against a serious invasion.” {Pioneer, supra, 40 Cal.4th at p. 370.) Whether a legally recognized privacy interest exists is a question of law, and whether the circumstances give rise to a reasonable expectation of privacy and a serious invasion thereof are mixed questions of law and fact, (ibid.) “ ‘If the undisputed material facts show no reasonable expectation of privacy or an insubstantial impact on privacy interests, the question of invasion may be adjudicated as a matter of law.’ ” (Ibid., quoting Hill v. National Collegiate Athletic Assn. (1994) 7 Cal.4th 1, 40 [26 Cal.Rptr.2d 834, 865 P.2d 633] (Hill).)
The Pioneer court employed the analytical framework set forth in Hill, supra, 7 Cal.4th 1, for evaluating claims of invasion of privacy under the California Constitution. As a starting point, the claimant must possess a
