Employment termination dispute; validity of dismissal and cost allocation in revision proceedings

The Federal Labour Court (BAG) dismissed the plaintiff's revision, thereby upholding the lower court's judgment and ordering the plaintiff to bear the costs of the revision proceedings. The case involved a dispute concerning the termination or validity of an employment relationship, where the plaintiff challenged the Regional Labour Court's decision following an unsuccessful appeal. While the specific statutory provisions and detailed factual matrix are not excerpted in the provided text, the court's final decision affirmed the procedural and substantive standing of the prior instance, resulting in a complete victory for the defendant party.
