May a private entity running a public access channel ban speakers based on the content of their speech—something a government entity running the same channels could not do? Yes, the Supreme Court held in a 5-4 opinion in Manhattan Community Access Corporation v. Halleck. Why? Because the First Amendment doesn’t apply to private entities in this instance.
The Cable Communications Policy Act of 1984 authorizes states and local governments to require cable operators to set aside channels on their cable systems for public access. Under New York law the cable operator operates the public access channels unless the local government chooses to do so or designates a private entity to do so.
New York City designated a private nonprofit, Manhattan Neighborhood Network (MNN), to operate the public access channels in Manhattan. MNN suspended two producers from its facilities and services after MNN ran a film they produced about MNN’s alleged neglect of the East Harlem community. The producers claimed MNN violated their First Amendment free speech rights when it “restricted their access to the public access channels because of the content of their film.”
