The 2010 United States Supreme Court case "Holder v. Humanitarian Law Project" ruled that organizations providing international law training to organizations recognized as terrorist groups by the Department of State are committing a crime. Because of Geneva Call's work with the Kurdistan Workers' Party, some of the organization's activities could be considered illegal under American law. Geneva Call President at the time Elisabeth Decrey-Warner responded that "civilians caught in the middle of conflicts and hoping for peace will suffer from this decision. How can you start peace talks or negotiations if you don't have the right to speak to both parties?"
