The European Union's Court of Justice (CJEU) said that national data watchdogs in Europe may act against companies, even if they are not lead regulators for the firms, in a blow to Facebook which has disputed the Belgian regulator's authority.
"Under certain conditions, a national supervisory authority may exercise its power to bring any alleged infringement of the GDPR before a court of a member state, even though that authority is not the lead supervisory authority with regard to that processing," the CJEU said.
Earlier, a Belgian court found Facebook guilty of violating privacy laws and ordered it to delete the collected user data.
