Employment law dispute: reversal of appellate judgment and dismissal of employee’s claim on merits

The Federal Labour Court (BAG) reversed the Regional Labour Court of Hesse and dismissed the employee's appeal, upholding the first-instance judgment in favor of the employer and ordering the employee to bear the costs of all appellate proceedings. The dispute concerned an employment law claim where the employee challenged a labor rights determination (likely regarding termination or compensation) after losing at the Frankfurt Labour Court. The decisive legal basis was the BAG's application of substantive employment law doctrines and the German Code of Civil Procedure, finding that the Regional Labour Court had erred in its factual or legal assessment, thereby restoring the lower court's finding that the employee's claims were unfounded.
