Whether the First Amendment's protections for freedom of speech and press restrict state action through the Fourteenth Amendment.
Holding
Yes. Freedom of speech and of the press are fundamental liberties protected against state abridgment by the Fourteenth Amendment.
Reasoning
The Court treated free expression as indispensable to democratic self-government. Speech allows citizens to discuss important issues, expose error, and form informed judgments through public debate rather than governmental suppression.
Because restrictions on speech threaten the public processes through which political and economic ideas are tested, courts must closely assess both the circumstances and the substantiality of the state's asserted justification for the restriction. A legislature's preference for a particular method of addressing an economic or social problem does not alone justify a burden on fundamental expressive rights.
