Admissibility and success of revision in labor dispute

The Federal Labour Court (BAG) dismissed the defendant's appeal and ordered them to bear the revision costs, thereby affirming the lower court's judgment. The dispute concerned a labor law matter, specifically challenging a prior appellate decision from the Cologne Labour Court of Appeals. The court's decision rests on the procedural outcome under German civil procedure rules regarding the admissibility and success of a revision appeal, upholding the substantive findings of the Landesarbeitsgericht Köln.
