Appellate courts generally review final judgments, not the running stream of rulings a trial court makes on the way to one. The final judgment rule exists to prevent piecemeal appeals — if every adverse ruling could be appealed the moment it issued, litigation would grind to a halt in a cycle of interruptions, and appellate courts would be reviewing the same case in fragments instead of as a coherent whole.

A judgment is generally "final" when it disposes of all claims against all parties, leaving nothing left for the trial court to do but execute the judgment. Rulings that resolve only part of the case — denying a motion to dismiss, granting partial summary judgment, most discovery orders — are typically not immediately appealable under this rule, though a set of recognized exceptions (like the collateral order doctrine, or a court's certification that partial judgment is appropriate) allow certain orders to be appealed before the case is fully over.

Juricratic treats finality as a gate on the simulated matter's appellate track — a projected appeal only becomes a live branch of the simulation once the modeled case reaches a state that actually qualifies as a final judgment (or fits a recognized exception), rather than assuming every adverse ruling is immediately appealable.

Litigators use the final judgment rule to plan appellate strategy: an unfavorable interim ruling, however painful, usually has to be preserved and revisited only after the whole case concludes, unless it fits a narrow interlocutory-appeal exception. Understanding this rule prevents wasted motions for immediate appeal and clarifies when the appellate clock — the deadline to file a notice of appeal — actually starts running.
