[Subject matter] and [decisive legal issue]

The Federal Labor Court rejected the plaintiff's revision appeal, upholding the lower court's judgment and ordering the plaintiff to bear the costs of the revision proceedings. The case involved a labor dispute where the plaintiff challenged a prior decision regarding his employment relationship, though the specific factual basis of the claim is not detailed in the provided excerpt. The ruling stands based on the lower court's assessment of the merits, as the appellate court found no grounds for further relief, effectively affirming the defendant's position in the litigation.
