Failure of employee's revision to overturn lower court dismissal of labor claim

The Federal Labour Court (BAG) dismissed the employee's revision appeal, upholding the Landesarbeitsgericht's judgment which had rejected his claims, and ordered him to bear the costs of the appellate proceedings. The dispute concerned a labor law matter where the employee challenged a lower court decision, but the specific subject matter and material facts are not detailed in the provided operative part (Tenor) of the decision. As the text contains only the procedural outcome and cost allocation without the "Tatsachen" (facts) or "Entscheidungsgründe" (reasoning), the specific legal norms or doctrines applied to reach this decision cannot be identified from the excerpt; the decision stands as a final rejection of the employee's legal arguments against the employer.
