Labor law dispute over employment rights; substantive application of labor statutes in revision proceedings.

The Federal Labour Court (BAG) rejected the plaintiff's revision, thereby upholding the Landesarbeitsgericht Niedersachsen's judgment from September 21, 2015, and ordering the plaintiff to bear the costs of the revision proceedings. The dispute concerned a labor law matter brought by the plaintiff against an employer, challenging a lower court's decision on the merits of the employment relationship. The BAG's decision confirms the lower instance's ruling as final and binding, with the specific legal basis tied to the procedural admissibility of the revision and the substantive labor law doctrines applied by the regional court, which the federal court found to be correctly applied without requiring further intervention on the plaintiff's grounds of appeal.
