Scope of dismissal for unproven claims in labor litigation following partial revision rejection

The Federal Labour Court (BAG) rejected the defendant's revision, effectively upholding the lower court’s judgment while amending the operative clause to explicitly dismiss the remainder of the plaintiff's claims; consequently, the plaintiff partially prevailed regarding the specific issues upheld by the appellate court, while the plaintiff’s additional claims were dismissed. The dispute involved a labor law matter where the plaintiff challenged aspects of the employment relationship or termination, leading to litigation through the Saxon Regional Labour Court. The decisive legal basis rests on the substantive labor law standards reviewed by the BAG, which found no error in the lower court's application of the law to the facts concerning the plaintiff's primary claims, thereby sustaining the validity of the Sächsisches Landesarbeitsgericht’s ruling.
