Determination: definition clarifies when an adjudicative act is final for appeal purposes and distinguishes orders that do not end disputes. A determination is an authoritative, judicial or quasi judicial expression that resolves a controversy by conclusively disposing of parties' rights; an order may be similar but need not end the dispute. For appealability, a determination is treated as a final judgment when the adjudicative body has completed adjudication of the parties' rights, distinguishing final dispositional acts from interlocutory measures.
