Interlocutory is a legal term which can refer to an order, sentence, decree, or judgment, given in an intermediate stage between the commencement and termination of a cause of action, used to provide a temporary or provisional decision on an issue. Thus, an interlocutory order is not final and is usually not subject to appeal.
In many legal systems, interlocutory orders are not appealable, except in a few extraordinary cases. When the case is concluded, any aspect of an interlocutory order that has not become moot may be challenged in an appeal from the final judgment.
