Does the right of privacy extend to nongovernmental actors as well as governmental actors?

In Schmidt v. Superior Court, supra, 48 Cal.3d 370, 256 Cal.Rptr. 750, 769 P.2d 932, we assumed but did not decide that the right of privacy reaches nongovernmental as well as governmental actors (id., 48 Cal.3d at p. 389, 256 Cal.Rptr. 750, 769 P.2d 932), noting that "we ha[d] no occasion in th[at] case to consider under what circumstances, if any, purely private action ... would constitute a violation of the state constitutional privacy provision" (id., 48 Cal.3d at p. 389, fn. 14, 256 Cal.Rptr. 750, 769 P.2d 932).
