Key Figures

View All

Frances Haugen

Former Product Manager, Civic Integrity Team

Haugen's disclosures provide key evidence for plaintiffs' "knowledge" allegations—proving that Meta knew its products harmed minors and chose not to act. Her documents are cited extensively in the Amended Master Complaint and discovery requests.

Hon. Yvonne Gonzalez Rogers

United States District Judge

As the presiding judge over MDL 3047, Judge Rogers has made several pivotal rulings that have allowed the case to proceed. Her November 2023 ruling distinguishing product design from content—thereby limiting Section 230 immunity—is the most significant legal development in the litigation and may reshape platform liability law.

Hon. Carolyn B. Kuhl

California Superior Court Judge

As the presiding judge over the California JCCP, Judge Kuhl oversees 800+ state court cases running parallel to the federal MDL 3047. Her October 2023 ruling allowing claims to proceed reinforced the viability of design-based product liability theories.
