Royal and Sun Alliance Ins. Co. of Canada v. Century International Arms, Inc.

RSA (plaintiff) sought reimbursement from its insured Century America (a Century International Arms (defendant) affiliate) after settling product-liability claims, and when unpaid, sued Century Canada in a Quebec court and separately sued Century America in the Southern District of New York. Century America moved to dismiss the U.S. action based on the pending parallel Canadian action and its own consent to Canadian jurisdiction, and the district court, despite recognizing its jurisdiction was normally mandatory, exercised discretion to dismiss anyway; RSA appealed.
