Court case III OSK 769/23 – Court Ruling (Poland, 2024)

The data subject is a former member of Jehovah's Witnesses (the controller). She left the organisation in 2020. The data that the controller has collected during the time of her membership was retained by the controller after her exit.

The Supreme Administrative Court has expressed or affirmed the following: # Processing of historical data of a former member of a religious organisation may be lawful under Article 6(1)(f) GDPR and does not have to be based on consent Article 6(1)(a) GDPR. # As the data is sensitive within the meaning of Article 9 GDPR, such processing of historical data of a former member will be lawful under Article 9(2)(d) GDPR (the internal processing by certain organisations), subject to appropriate technical safeguards. # Data regarding former members which relate to ongoing court proceedings should be processed on the basis of Article 9(2)(f) GDPR (exercise or
