Judge Allows Key Claims Against Meta to Move Forward On Monday, U.S.

District Judge Yvonne Gonzalez Rogers denied Meta's request to dismiss claims accusing the company of deceiving the public, engaging in unfair business practices and violating the federal Children's Online Privacy Protection Act, or COPPA, Reuters reported.

The judge also granted summary judgment to the states on a key COPPA issue, finding that Meta failed to comply with the law's notice and parental consent requirements.
