Scope of BAG review where appellate court reformed first-instance judgment in employee's favor

The Federal Labor Court reversed the Lower Labor Court's appellate judgment, reinstating the lower-instance decision in favor of the defendant and dismissing the plaintiff's appeal in its entirety, thereby ordering the plaintiff to bear the costs of the second-instance and revision proceedings. The dispute concerned a claim by the employee, which was initially rejected by the Labor Court, overturned by the appellate court, and then challenged by the employer in a final revision proceeding. Although the specific statutory norms are not detailed in the provided text, the court applied labor law doctrines to determine that the employee's claims lacked legal merit under the applicable framework, resulting in a final victory for the employer.
