Major Meta trial begins as lawyers spar over witnesses, damages

A landmark social media trial involving Facebook parent Meta is set to begin in California on Tuesday, with attorneys clashing over witnesses and potential financial penalties. The four states selected to represent a coalition suing Meta argue that the company deliberately designed Facebook and Instagram to be addictive for children, violating state and federal laws.

Meta, which has over three billion global users, attempted to block an ex-employee and expert witness, Arturo Bejar, from testifying, but a federal judge ruled against the company, describing it as a "Hail Mary" attempt to eliminate a strong witness for the plaintiffs. Bejar's upcoming testimony will address Meta's practices regarding safety and growth, and whether the company misrepresented its knowledge.

Meta is also challenging the scope of testimony from another potential expert witness, Colin Gray, who will be questioned about "dark patterns" - features designed to manipulate users into making preferred choices. The states seek around $200 billion in financial penalties from Meta, though they believe the figure was exaggerated for shock value.

In addition to monetary damages, the states are demanding changes to Meta's apps. An advisory jury of eight people was selected, and the judge will make the final decision. The six-week trial is expected to reach a verdict by early October, potentially marking a significant turning point for Meta amidst broader concerns about mental health and safety issues on social media platforms.
