Broadrick v. Oklahoma, 413 U.S. 601 (1973), is a United States Supreme Court decision upholding an Oklahoma statute which prohibited state employees from engaging in partisan political activities. Broadrick is often cited to enunciate the test for a facial overbreadth challenge that "the overbreadth of a statute must not only be real, but substantial as well, judged in relation to the statute's plainly legitimate sweep."
