The court's conservatives voiced concern that allowing such lawsuits violated international law, that it created tensions with foreign nations and that the U.S. law only applied to acts by individuals, not to corporations…The case has been closely watched by corporations concerned about long and costly litigation in the United States and by human rights advocates who say businesses can be held accountable in U.S. courts for their alleged role in torture, executions or other abuses committed abroad.
