Federal labor court rejection of employee's revision appeal on undisclosed labor claim

The German Federal Labor Court (BAG) dismissed the employee's revision appeal, leaving the prior judgment in force and ordering the employee to bear the costs of the proceedings. The dispute concerned a labor law claim where the employee challenged a lower court decision, specifically reversing the outcome of the Hessian Higher Labor Court. In its decisive legal assessment, the BAG found no grounds to overturn the appellate court’s reasoning, thereby upholding the interpretation of the relevant labor regulations applied by the lower instance against the employee's arguments.
