CJEU rules controllers must explain process behind automated decisions

27/02/2025 | CJEU

The Court of Justice of the European Union (CJEU) has ruled in Case C-203/22 that individuals have the right to understand the "procedure and principles actually applied" in making automated decisions under Article 15(1)(h) of the EU General Data Protection Regulation (GDPR). 

The CJEU ruled that this includes clarifying the types of personal data used and in what capacity in the automated decision-making process. Interfering trade secrets must be disclosed to the court or data protection authority (DPA) so that they may determine the extent of the data subject’s right of access. 

The case relates to a decision by an Austrian court, which found Dun & Bradstreet violated the EU General Data Protection Regulation (GDPR) after it failed to provide a customer with "meaningful information about the logic involved" in an automated decision. The company argued that sharing this information would require disclosing protected trade secrets.
