Facebook shareholders cleared a major hurdle Wednesday afternoon in their derivative case involving the platform’s security policies and the related Cambridge Analytica data breach, with Vice Chancellor J. Travis Laster declining to dismiss the large majority of their claims.

Ruling from the bench, Laster said the shareholders’ “encyclopedic,” nearly 400 pages of well-pled claims are more than enough to get most past the motion to dismiss stage, in which facts are viewed in favor of the plaintiff.
