Revision appeal in labor law dispute; appellate costs allocation to plaintiff

The Federal Labor Court (BAG) dismissed the plaintiff's revision, thereby upholding the decision of the Düsseldorf Regional Labor Court and leaving the lower court’s judgment in force, with the plaintiff ordered to bear the costs of the appellate proceedings. The dispute concerned a labor law matter where the employee challenged a prior ruling, though the specific subject matter and underlying facts are not detailed in the provided excerpt. The decision relied on the established legal standards applicable to the revision instance in German labor law, resulting in the rejection of the appellant's arguments and the affirmation of the lower court's findings.
