Dispute over finality of labor court judgment after dismissal of revision by Federal Labor Court

The Federal Labor Court (BAG) dismissed the plaintiff's revision, thereby upholding the judgment of the Thuringian Regional Labor Court, which remains in force, and ordered the plaintiff to bear the costs of the appellate proceedings. The dispute centered on a labor law claim where the plaintiff appealed a lower court decision, resulting in a final defeat for the appellant at the highest labor court level. The decisive legal basis involves the application of labor law standards governing the specific subject matter of the original action, with the court affirming the lower instance's legal assessment and fact-finding, thereby ending the litigation without granting the relief sought by the plaintiff.
