Employment law dispute: Rejection of employer’s revision challenging lower court’s labor rights ruling

The Federal Labor Court (BAG) dismissed the defendant-employer’s revision, upholding the Regional Labor Court of Cologne’s judgment in favor of the plaintiff-employee and ordering the defendant to bear the costs of the proceedings. The dispute concerned a labor law claim, specifically addressing issues of employment rights or termination validity where the employee successfully challenged the employer's position in the lower instances. The decisive legal basis relied on general labor law principles and statutory interpretations regarding the employer’s failure to substantiate its defenses, resulting in the maintenance of the lower court’s findings against the employer.
