The most difficult part of [taekwondo] is … taking the first step across the threshold of the dojang door.” ― Doug Cook. This case is about the threshold issue of appellate court jurisdiction over an interlocutory appeal from a denial of a motion to dismiss claiming Foreign Sovereign Immunities Act (FSIA) immunity and asserting the Act of State Doctrine. Denial of FISA immunity is immediately appealable in federal court. CRS 13-4-102 only permits appeals from final judgments. The court of appeals held it had jurisdiction over the FISA order and affirmed, citing federal law, principles of neutrality between state and federal courts and sound appellate practice. But, it lacked jurisdiction over the Act of State Doctrine appeal because the Doctrine is a form of preclusion based on facts. Finally, it held that Colorado courts of appeals do not have pendent appellate jurisdiction.
