Labor law dispute: Rejection of revision against prior instance judgment

The Federal Labour Court (BAG) rejected the plaintiff's revision, affirming the decision of the Hessian Regional Labour Court and ordering the plaintiff to bear the costs of the appellate proceedings. The case concerned a labor law dispute, specifically regarding the consequences of a prior instance decision (17/7 Sa 1792/09), though the specific subject matter of the claim is not detailed in the provided operative text. The court's refusal to overturn the lower court's judgment indicates that the plaintiff's legal arguments failed to meet the standard for revision, thereby leaving the previous instance's ruling in force. No specific statutory norms or doctrines are explicitly cited in the provided excerpt, but the outcome reflects the final judgment in favor of the defendant (or upholding the status quo against the plaintiff's appeal).
