On March 7, 2024, the Court of Justice of the European Union (the “CJEU”) handed down its judgment in the IAB Europe case, answering a request for a preliminary ruling under Article 267 TFEU from the Brussels Market Court.[1] The case revolves around IAB Europe’s Transparency and Consent Framework (“TCF”) and has been closely monitored by the AdTech industry ever since the Belgian DPA investigated and subsequently imposed a 250,000 euro fine on IAB Europe for alleged breaches of GDPR and e-Privacy rules back in 2022.[2]
