Challenging the admissibility and merits of a revision in a labor dispute where the appellant failed to substantiate the appeal against the lower court's judgment.

The Federal Labour Court (BAG) dismissed the plaintiff's revision, upholding the decision of the Hessian Labour Court of Appeal and ordering the plaintiff to bear the costs of the revision proceedings. The dispute concerned a labour law matter where the plaintiff appealed against the lower court's judgment, but failed to persuade the higher court to overturn the ruling. The court applied standard labour law doctrines to determine that the plaintiff's claims were not substantiated or were legally unfounded, resulting in the full rejection of the appeal.
