A federal magistrate judge ordered Facebook and plaintiffs in a proposed class action stemming from the company’s Cambridge Analytica scandal to regularly hop on video conference calls to squash an ongoing discovery dispute.

U.S. District Magistrate Judge Jacqueline Scott Corley of the Northern District of California told Facebook’s lawyers from Gibson, Dunn & Crutcher and plaintiffs counsel from Keller Rohrback and Bleichmar Fonti & Auld to meet and confer via video conferencing platform Zoom, not letters or email.
