The Communications Decency Act was an attempt to protect minors from explicit material on the Internet by criminalizing the knowing transmission of "obscene or indecent" messages to any recipient under 18; and also the knowing sending to a person under 18 of anything "that, in context, depicts or describes, in terms patently offensive as measured by contemporary community standards, sexual or excretory activities or organs." The American Civil Liberties Union argued that certain parts of the act were facially unconstitutional and sought a preliminary injunction preventing the government from enforcing those provisions.
