Whether § 6 of the Enforcement Act reached a conspiracy to interfere with any right described in the indictment, or only with a right granted or secured by federal law.
Holding
Only interference with a right granted or secured by the Constitution or laws of the United States could support a federal conviction under § 6; the indictment had to show that the targeted right was federal in character.
Reasoning
The statute did not make banding together or conspiring criminal by itself. It punished a combination formed with the specified intent to prevent or hinder a citizen’s exercise of a right or privilege granted or secured by federal law. Thus, the indictment had to identify conduct that fell within federal authority rather than merely allege a private conspiracy to commit wrongdoing within a State.
The Court stressed the distinction between national and state citizenship. The federal government possesses only delegated powers, while the States retain responsibility for protecting the broad range of civil and natural rights that the Constitution did not place under national protection. A single act may offend both governments, but that overlap does not give the national government a general police power.
