In the first phase, jurors had ordered $US375 million ($A533 million) in civil penalties against Meta, determining that it knowingly harmed children's mental health and concealed what it knew about child sexual exploitation on its platforms. The court said federal children's privacy laws prevent Meta from applying age-verification tools to children under 13. The court also noted that ordering Meta to verify children's ages for only Meta and not other social media companies would be "inequitable and unduly injurious" to the company.
