Holder v. Humanitarian Law Project was a landmark Supreme Court case decided in 2010 that addressed the constitutionality of a provision in the USA PATRIOT Act, which made it a crime to provide 'material support' to foreign terrorist organizations. The case centered on whether the law violated free speech rights under the First Amendment, as the Humanitarian Law Project sought to offer training and legal advice to a Kurdish group considered a terrorist organization by the U.S. government.
