Dismissal of labor law revision after BAG reversal and cost allocation

The Federal Labour Court (BAG) reversed the appellate decision and dismissed the plaintiff's claim, resulting in a complete victory for the defendant. The dispute concerned an employment law matter where the plaintiff challenged a determination made by the defendant, and the case was heard on revision following the Landesarbeitsgericht Düsseldorf's judgment. The BAG concluded that the lower courts erred in their assessment, thereby upholding the defendant's position and ordering the plaintiff to bear the costs of the litigation across all instances. No specific statutory norms were detailed in the provided excerpt, but the decision reflects the BAG's final authority in reviewing labor disputes and correcting legal errors in prior rulings.
