Van Cauwenberghe v. Biard

Background

A real estate broker in Brussels persuaded a Brussels resident to lend $1 million to a U.S. real estate partnership. The partnership defaulted, U.S. prosecutors later indicted the broker, and he was extradited from Switzerland to Los Angeles, tried, convicted, and sentenced. The lender then sued the broker in federal court in California. The broker moved to dismiss, claiming immunity from civil process because of his extradition and also asking dismissal on the ground that the U.S. forum was inconvenient. The district court denied both motions, and the broker appealed. The Court of Appeals dismissed the appeal for lack of jurisdiction, and the Supreme Court reviewed that jurisdictional ruling.

Reasoning

The core question was whether orders denying dismissal for extradition-based immunity or for forum non conveniens are immediately appealable under the final-judgment rule in 28 U.S.C. §1291. The Court applied the collateral-order test, which requires an order to decide a separate, conclusively resolved issue that cannot be effectively reviewed later. The Court assumed the broker had a substantial immunity claim but concluded the claimed right did not amount to an essential right not to stand trial. The specialty principle protects treaty obligations but does not necessarily bar a private civil trial, and challenges to personal jurisdiction concern being subject to a binding judgment, which can be reviewed after final judgment. Forum non conveniens inquiries are often entangled with the case’s facts and merits and thus are usually unsuitable for immediate appeal.

Real world impact

The Court held that neither denial is a collateral order appeal under §1291, so the appeals court lacked jurisdiction. Affected defendants generally must wait for final judgment to appeal these rulings, though limited interlocutory review may be possible through statutory certification in special cases.
