Corso obtained a default judgment against Rejuvi in a district court in South Australia.  Corso filed a proof of claim in Rejuvi’s bankruptcy proceeding.  Rejuvi appealed from a bankruptcy court order allowing Corso’s claim based on the South Australia default judgment.  Held, the claim was properly allowed.  Under California’s Uniform Foreign-Country Money Judgment Recognition Act (CCP 1713 et seq.), Rejuvi waived its challenge to personal jurisdiction in the South Australia court by voluntarily appearing in that court on a motion to set aside the default judgment and raising merits-based arguments in support of the motion.  The Uniform Act shields from waiver only an appearance to argue lack of personal jurisdiction.
