Failure of employment claim in revision proceedings: scope of labor law claims against employer

The Federal Labor Court (BAG) ruled in favor of the defendant, partially reversing the appellate decision and dismissing the plaintiff's claims in their entirety, thereby upholding the lower court's dismissal and ordering the plaintiff to bear the litigation costs. The case involved a dispute over individual employment law, where the plaintiff sought relief from the defendant, likely challenging aspects of the employment relationship or termination, though the specific subject matter is not detailed in the provided text. The decisive legal basis for the judgment rests on the court's application of substantive labor law principles, resulting in the rejection of the plaintiff's statutory or contractual claims against the employer.
