Meta’s (META.O) Facebook and the U.S. Federal Trade Commission lost the most recent round of their legal dispute over privacy on Monday. A federal judge decided that the regulator may attempt to lower the amount of money the social media giant receives from users who are younger than 18.

The judge said that Facebook would have to submit to an examination of a previous settlement company reached with the FTC.

Meta submitted a motion asking the court to intervene in the fight, but Judge Timothy Kelly of the U.S. District Court for the District of Columbia dismissed it.

The FTC has argued that it was up to the agency to decide whether its settlements should be changed and that the district court had no jurisdiction. A commission decision can be appealed to the relevant appeals court.

The FTC proposed changing a settlement reached in 2019 which required Facebook to pay $5 billion. The FTC said it would tighten that to bar Facebook from making money off data collected on users under age 18, including in its virtual reality business. It would also face expanded limitations on using facial recognition technology.
