CJEU - C‑414/24 - Datenschutzbehörde (Articulation des recours)

CJEU rules supervisory authorities cannot reject GDPR complaints solely due to ongoing judicial proceedings.

The Court of Justice of the European Union (CJEU) has ruled that a data protection supervisory authority cannot reject a complaint solely because the data subject has already initiated judicial proceedings on the same matter. This decision clarifies that the right to lodge a complaint with a supervisory authority under GDPR is independent of the right to a judicial remedy against a controller or processor.

The lesson from this incident

Full lesson

The CJEU clarified that data subjects retain the right to file complaints with supervisory authorities (such as a Data Protection Authority) even when they have already pursued judicial remedies against a controller or processor. Organizations that assumed parallel proceedings would neutralize regulatory scrutiny were operating under a flawed legal assumption. This ruling reinforces that GDPR provides layered, independent enforcement pathways — supervisory, judicial, and civil — that cannot be used to obstruct one another. Failing to recognize this distinction exposes organizations to simultaneous regulatory investigations and court actions, compounding legal and reputational risk.
