Dismissal of revision challenging prior labor court ruling on individual claim

The Federal Labour Court (BAG) dismissed the claimant's revision, upholding the Landesarbeitsgericht decision and ordering the claimant to bear the costs of the revision proceedings. The case concerned a dispute where the claimant sought a remedy or declaration against the defendant, challenging the outcome of the lower court instance. The court's ruling confirms the validity of the prior judgment, leaving the previous instance's determination in force. The decisive legal basis rests on the procedural and substantive labour law norms applicable to the specific claim, resulting in the final rejection of the claimant's arguments on appeal.
