Rossi Foti (plaintiff) engaged in picketing, leafleting, and counseling outside clinics operated by Planned Parenthood Golden Gate (Planned Parenthood) (defendant). Foti sued Planned Parenthood, alleging that Planned Parenthood employed escorts that interfered with Foti’s sidewalk protests. Through discovery, Foti sought the names, addresses, and telephone numbers of Planned Parenthood staff and volunteers with knowledge of the case’s facts. Planned Parenthood objected, claiming that disclosing names and contact information would violate the nonparties’ right to privacy under the California Constitution. Planned Parenthood offered to: (1) identify the relevant staff and volunteers through pseudonyms, (2) facilitate contact at Planned Parenthood’s office, and (3) accept service on their behalf. After several motions, the trial court ordered Planned Parenthood to provide the requested disclosures under a protective order that said: (1) the individuals’ names would be disclosed on a litigation-only basis, prohibiting the disclosure of these names outside of the litigation, and (2) the individuals’ addresses and phone numbers would be disclosed on an attorneys-eyes-only basis. Planned Parenthood appealed.
