interlocutory appeal

The term “ interlocutory ” is used to indicate a lack of finality. An interlocutory appeal is an appeal of a non-final order issued during the course of litigation .

The collateral order doctrine sets forth the rules for such appeals. Interlocutory appeals are extremely rare, and a three-part test determines whether the collateral order exception to res judicata makes such an appeal possible:

  1. The order must have conclusively determined the disputed question;
  2. The order must “resolve an issue completely separate from the merits of the action”;
  3. The order must be “effectively unreviewable on appeal from a final judgment.”
