The US Supreme Court held 5–4 that the freedom of speech clause of the First Amendment prohibits the government from restricting independent expenditures for political campaigns by corporations, including nonprofit corporations, labor unions, and other associations.
Justice Stevens argued that the majority's decision failed to recognize the **dangers** of the corporate form. Austin held that the prevention of **corruption**, including the distorting influence of a dominant funding source, was a sufficient reason for regulating corporate independent expenditures.
