The Federal Trade Commission (FTC) and California Attorney General Kamala Harris have each filed amicus briefs with a court of appeals disputing the interpretation of child privacy law in a federal case involving Facebook.

In the case, Facebook users sued the social media giant for using their images in ads placed on the service without their consent. While the class-action was settled, children’s advocates are asking the court of appeals to dissolve the settlement in hopes of requiring “explicit permission” from parents before using the personal information of teens, according to a report by the Los Angeles Times.

Both the agency and attorney general believe that Facebook’s interpretation of the Children’s Online Privacy and Protect Act is flawed even though the company argues the law protects kids 12 and under.
