A 1993 Colorado statute regulated speech-related conduct within one hundred feet of the entrance to any health care facility. The statute made it unlawful for any person to knowingly approach another person within eight feet, without that person’s consent, “for the purpose of passing a leaflet or handbill to, displaying a sign to, or engaging in oral protest, education, or counseling with such other person.” The ordinance did not place any restrictions on the content of the message. Leila Hill (plaintiff) was a sidewalk counselor who offered information about abortion alternatives to women entering health care facilities for abortion services. She and other counselors brought suit against the state of Colorado (defendant) in state court seeking to enjoin enforcement of the statute on the grounds that it violated the First Amendment. The trial court held the statute was a reasonable, content-neutral time, place, and manner regulation. The Colorado Supreme Court affirmed, and the United States Supreme Court granted certiorari.
