Labour law dispute over employer’s liability for alleged wrongful termination; adequacy of lower court’s factual and legal assessment on appeal

The German Federal Labour Court (BAG) dismissed the defendant employer's appeal, upholding the Lower Labour Court of Cologne's judgment and ordering the defendant to bear the costs of the revision proceedings. The dispute concerned the employment relationship, specifically challenging the prior instance's findings on the employer's liability or claim arising from the termination or performance of the contract. The court’s decision rested on the application of German labour law principles, confirming that the employer's arguments did not merit a reversal of the lower court's factual and legal assessment in favor of the employee.
