In United States v. Moylan, 417 F.2d 1002 (4th. Cir. 1969), Fourth Circuit Court of Appeal unanimously ruled: "If the jury feels that the law under which the defendant is accused is unjust, or exigent circumstances justified the actions of the accused, or for any reason which appeals to their logic or passion, the jury has the right to acquit, and the courts must abide that decision." The Fully Informed Jury Association is a non-profit educational organization dedicated to informing jurors of their rights and seeking the passage of laws to require judges to inform jurors that they can and should judge the law. In Sparf v. United States, 156 U.S. 51 (1895), the Supreme Court, in a 5-4 decision, held that a trial judge has no responsibility to inform the jury of the right to nullify laws.
Modern American jurisprudence is generally intolerant of the practice, and a juror can be removed from a case if the judge believes that the juror is aware of the power of nullification.[23]
