The Doctrinal Timeline

Decision Year Effect on Anti-Subversion Law
Schenck v. United States 1919 Upheld Espionage Act; coined 'clear and present danger' (narrow test)
Abrams v. United States 1919 Upheld convictions; Holmes/Brandeis dissents planted broader free-speech protection
Dennis v. United States 1951 Smith Act convictions of top Communist Party leaders upheld 6–2
Yates v. United States 1957 Smith Act reversed for lower-level party members; abstract advocacy protected
Noto v. United States 1961 Smith Act narrowed further — only concrete preparations for violence, not doctrine
Brandenburg v. Ohio 1969 Current standard: speech protected unless directed to AND likely to produce imminent lawless action
Albertson v. SACB 1965 Compelled Communist Party registration violated Fifth Amendment — gutted McCarran Act
