Dispute over labor law claims; revision dismissed

The Federal Labour Court (BAG) dismissed the defendant's revision appeal, upholding the Lower Labour Court of Cologne's judgment and ordering the defendants to bear the costs of the revision proceedings as joint debtors. The dispute concerned a labor law claim where the plaintiff successfully challenged the defendant's position in the lower courts. The court's decision affirmed the lower instance ruling, leaving the original judgment in force based on the applicable procedural and substantive labor law norms that favored the plaintiff's position.
