A majority of Supreme Court justices raised doubts on Tuesday over whether Daimler AG can be sued in federal court for allegations that a subsidiary violated the human rights of workers at a plant in Argentina in the 1970s. During an hour-long oral argument, several justices on both sides of the court's ideological divide voiced concerns about how the…9th U.S. Circuit Court of Appeals handled the case when it ruled in favor of human rights plaintiffs, raising the possibility of the case ultimately being sent back to that court for further review. The argument focused on complex legal questions about when federal courts have jurisdiction over certain types of cases.
