Dispute over the admissibility and merits of a labor law claim on appeal.

The Federal Labor Court (BAG) dismissed the plaintiff's revision, upholding the judgment of the Hessian State Labor Court and ordering the plaintiff to bear the costs of the appellate proceedings. The dispute concerned a labor law matter, with the plaintiff challenging the lower court's ruling on specific employment-related claims, which the appellate court rejected on procedural and substantive grounds. The final decision affirmed the lower instance's outcome, leaving the original judgment in force. The court's ruling relied on the standard of review for revision proceedings and the applicable labor law doctrines governing the contested employment issues, resulting in no change to the prior adjudication.
