State Action Doctrine
The constitutional doctrine limiting First Amendment protections to government action, not private actors.
The state action doctrine holds that constitutional rights, including First Amendment rights, only protect against government action — not the actions of private individuals, companies, or organizations.
The practical effect for free speech law is significant: social media platforms, private employers, schools, and other private actors can restrict speech without violating the First Amendment. A Twitter ban, a private university speech code, or an employer's policy against political speech in the workplace may raise ethical concerns but does not implicate constitutional rights.
The state action doctrine is subject to exceptions: - Entanglement: When a private actor exercises powers traditionally reserved to the government, or when the government heavily regulates and supports the private actor, state action may be found - Public function: When a private entity performs a function traditionally and exclusively performed by the government, it may be treated as a state actor
The Supreme Court has generally declined to extend state action to private companies, even very powerful ones. The question of whether dominant social media platforms should be treated as state actors — or subjected to First Amendment-like obligations — is a major ongoing debate in free speech law.
Many states have enacted 'free speech' statutes that extend broader protections than the federal First Amendment by applying free speech protections to private employers or platforms.
