What is the test for making an interlocutory order?

interlocutory order is informed by the law-of-the-case doctrine, which provides that when a court has ruled on an issue, that decision should generally be adhered to by that court in subsequent stages in the same case. Uccio, 940 F.2d at 758. The decision whether or not to apply law-of-the-case is, in turn, informed principally by the concern that disregard of an earlier ruling not be allowed to prejudice the party seeking the benefit of the doctrine. Id.; see also Zdonok v. Glidden Co., 327 F.2d 944, 953 (2d Cir. 1964) (Friendly, J.) (stating that the doctrine of the law of the case is addressed to the court's "good sense").
