Dismissed for lack of appellate jurisdiction.
Defendants argue that the bond condition was an abuse of discretion.
For the reasons that follow, we conclude that the district court's order is not appealable, and we therefore dismiss for lack of appellate jurisdiction. An order vacating a default judgment, permitting the litigation to proceed, plainly does not fall within any of the above statutory categories. Nor is the requirement of a bond, imposed by the court as a condition for vacatur of the default, an appealable order. See, e.g., Trustees of Hospital Mortgage Group v. Nor is such a condition a final order, since it leaves all pending issues unresolved.
