Labor law dispute: validity of a Regional Labour Court judgment on employer’s appeal before the Federal Labour Court.

The Federal Labour Court dismissed the defendant's appeal, upholding the prior judgment of the Hessian Regional Labour Court and ordering the defendant to bear the costs of the revision proceedings. The dispute concerned a labor law matter, specifically a challenge brought by the employer against a lower court decision, though the specific substantive claims are not detailed in the provided operative part. The court’s decision rests on the application of German labor law principles as adjudicated by the BAG 10th Senate, affirming the procedural and substantive validity of the Regional Labour Court's ruling in case No. 18 Sa 1986/10.
