On October 5, 2015, the Supreme Court heard oral argument in OBB Personenverkehr AG v. Sachs. This case involves a dispute regarding whether federal courts have jurisdiction over a lawsuit brought by Carol Sachs against OBB Personenverkher--the Austrian national railroad--when her legs were crushed by a train in Austria while she was using a Eurail Pass that she had purchased in the United States. -- The question before the Supreme Court is twofold: (1) whether common law principles of agency apply in determining whether an entity is an “agent” of a foreign state under the Foreign Sovereign Immunities Act of 1976 (FSIA); and (2) whether, under the first clause of the commercial activity exception of the FSIA, a tort claim for personal injuries suffered in connection with travel outside of the United States is “based upon” the allegedly tortious conduct occurring outside of the United States, or the preceding sale of the ticket in the United States for the travel entirely outside the United States. -- To discuss the case, we have Edwin D. Williamson, who is Of Counsel at Sullivan & Cromwell LLP.
