Though the defendant did not appear and defaulted, it did not thereby waive any objection to personal jurisdiction.  A trial court may and should determine its own subject matter and personal jurisdiction before entering a default judgment to assure that it is not a void decree.  Here, the trial court properly gave plaintiff notice of its doubt that it had jurisdiction, giving plaintiff an opportunity to present evidence and argument on the subject before ruling.  The trial court correctly held that it lacked personal jurisdiction over Al Shabaab.  That organization is not “at home” in the United States and so is not subject to general personal jurisdiction here.  Al Shabaab’s few known contacts with California had no connection with the attack on a hotel abroad during which plaintiff’s decedent was killed.  So California also lacked specific personal jurisdiction over Al Shabaab.
