Key facts of the case:

2. The request has been made in proceedings between Mr Las and his former employer, PSA Antwerp NV (‘PSA Antwerp’), concerning payment by the latter of various sums following his dismissal.
Results (sanctions) and key consequences of the case:
On those grounds, the Court (Grand Chamber) hereby rules:
Article 45 TFEU must be interpreted as precluding legislation of a federated entity of a Member State, such as that in issue in the main proceedings, which requires all employers whose established place of business is located in that entity’s territory to draft cross-border employment contracts exclusively in the official language of that federated entity, failing which the contracts are to be declared null and void by the national courts of their own motion.
