Lawfulness of termination; reversal of appeal affirming employee’s claim

The Federal Labour Court overturned the appellate decision, reversing the lower court's partial success for the employee and upholding the employer's appeal, thereby dismissing the employee's claims in full and ordering them to bear the costs of the second and third instances. The dispute concerned an unlawful termination, specifically challenging the lawfulness of the dismissal and the validity of any subsequent legal remedies or claims for continued employment or severance. The decisive legal basis involved the statutory protections against dismissal (Kündigungsschutzgesetz), with the court determining that the employer's termination complied with the necessary substantive and formal legal requirements, rendering the dismissal lawful.
