Admissibility of revision appeal in labor dispute

The Federal Labour Court (BAG) dismissed the defendant's revision, upholding the lower court's judgment and ordering the defendant to bear the costs of the appeal proceedings. The case involved a labor law dispute where the defendant appealed a Landesarbeitsgericht Berlin-Brandenburg decision, likely concerning a contested employment matter such as termination or contractual rights. The final operative outcome confirms that the claimant prevailed, with the appellate court rejecting the defendant's arguments against the prior instance's ruling. No specific statutory provisions are detailed in the provided text, but the procedural framework is a final revision hearing on a civil/labor law matter, resulting in a full reversal of any attempt by the defendant to overturn the lower court's findings.
