Miles Edward Haynes was a convicted felon who was charged with failing to register a firearm under the Act.
Haynes argued that, because he was a convicted felon and thus prohibited from owning a firearm, requiring him to register any firearms in his possession was requiring him to make an open admission to the government that he was in violation of the law, which was essentially a violation of his right not to incriminate himself.
Earl Warren dissented in a one sentence opinion and Thurgood Marshall did not participate in the ruling.
As with many other 5th amendment cases, felons and others prohibited from possessing firearms could not be compelled to incriminate themselves through registration.
The court held: "To eliminate the defects revealed by Haynes, Congress amended the Act so that only a possessor who lawfully makes, manufactures, or imports firearms can and must register them", United States v. Freed, 401 U.S. 601 (1971).
