Labor law dispute where the Federal Labour Court dismissed the revision without altering the lower court's judgment

The Federal Labour Court (BAG) dismissed the plaintiff's revision, thereby upholding the judgment of the Lower Saxon Labour Court, and ordered the plaintiff to bear the costs of the revision proceedings. The dispute concerned a labor law matter where the plaintiff challenged the lower court's decision, but the BAG found no legal grounds to overturn it. As the substantive reasoning and specific statutory norms are not detailed in the provided excerpt, the decision rests on the appellate court's confirmation that the lower court's application of law and facts was correct, resulting in a final victory for the defendant.
