CJEU rules gender identity not required when purchasing a train ticket

09/01/2025 | CJEU

On Wednesday, 8 January 2025, the Court of Justice of the European Union (CJEU) ruled in Case C-394/23 that an individual's gender identity is not required when purchasing a train or transport ticket. The ruling relates to a challenge brought by the French association Mousse against the French data protection authority (CNIL) concerning its decision involving the data collection practices of SNCF, the country's railway operator. Mousse argued that SNCF's requirement for customers to select a title, either 'Monsieur' or 'Madame' (Mr or Ms), when purchasing tickets online violated the data minimisation principle under Article 5(c) of the EU General Data Protection Regulation (GDPR). 

The CJEU agreed, saying that an individual's gender identity is not "objectively indispensable, in particular where its purpose is to personalise commercial communication."
