Sweezy v. New Hampshire, 354 U.S. 234 (1957), was a case before the United States Supreme Court in which the Court ruled that jailing an academic when he refused to answer questions about university lectures he had given was a violation of due process. On a larger scale, the decision established constitutional protections for academic freedom and reined in the investigative powers of state legislatures.
