The possibility of a change in substantive law should ordinarily not be given conclusive or even substantial weight in the forum non conveniens inquiry. In Canada Malting Co. v. Paterson Steamships, Ltd., 285 U. S. 413 (1932), the case arose out of a collision between two vessels in American waters. The Canadian owners of cargo lost in the accident sued the Canadian owners of one of the vessels in Federal District Court. The cargo owners chose an American court in large part because the relevant American liability rules were more favorable than the Canadian rules. The District Court dismissed on grounds of forum non conveniens. The plaintiffs argued that dismissal was inappropriate because Canadian laws were less favorable to them. The Court nonetheless affirmed: 'We have no occasion to enquire by what law the rights of the parties are governed, as we are of the opinion that, under any view of that question, it lay within the discretion of the District Court to decline to assume jurisdiction over the controversy. . . . '[T]he court will not take cognizance of the case if justice would be as well done by remitting the parties to their home forum.''
