Dismissal of revision in labor dispute without citation of substantive legal norms in dispositive

The Federal Labour Court (4th Senate) dismissed the plaintiff's revision, leaving the lower court's judgment in force and ordering the plaintiff to bear the costs of the appellate proceedings. The dispute concerned a labor law claim where the plaintiff challenged the initial judgment on appeal. While the specific subject matter and material facts are not detailed in the provided text, the final operative outcome confirmed the defendant's position by rejecting the plaintiff's highest-level appeal. The decision relies on the procedural standard for revision dismissals under German labor law, indicating that the lower court's assessment did not suffer from the legal errors required to overturn the verdict, thereby upholding the prior instance's ruling without specifying the underlying substantive norms in this excerpt.
