Court of Justice (Ninth Chamber) 4 October 2024, C-621/22 (Koninklijke Nederlandse Lawn Tennisbond v Autoriteit Persoonsgegevens.)

Also known as

The Court addressed a preliminary ruling concerning the interpretation of "legitimate interests" under Article 6(1)(f) of the GDPR in the context of the Koninklijke Nederlandse Lawn Tennisbond's (KNLTB) disclosure of its members' personal data to sponsors without consent. The Court concluded that such processing may be justified as necessary for legitimate interests only if it is strictly necessary and does not override the fundamental rights of the data subjects. The ruling clarified that while the legitimate interest does not need to be defined by law, it must be lawful and carefully assessed against the rights of the individuals involved.AI
