Bottom line: A US Supreme Court decision declaring independent supervisory authorities unconstitutional jeopardizes the legal basis of the EU-US data transfer agreement.
The US Supreme Court has ruled independent US supervisory authorities unconstitutional. This calls into question the legal foundations of the Trans-Atlantic Data Privacy Framework, which governs data transfers from EU citizens to US cloud services.
The Trans-Atlantic Data Privacy Framework is based on an adequacy decision by the EU Commission, which permits data transfers from EU citizens to the United States under certain conditions. This regulation relies on, among other things, the supervisory function of independent US authorities.
The US Supreme Court has recently decided that several independent US supervisory authorities in their current form are unconstitutional. This decision could undermine the structural prerequisites on which the data transfer agreement is based.
For Chief Data Officers and data protection officers in the EU, this is relevant because they must verify the lawfulness of data flows to US cloud infrastructure. A reorganization of US supervisory authorities could change the status of the agreement and force companies to adapt their data transfer strategies or explore alternative solutions such as data localization or data encryption.
