Jury - Jury Nullification

Jury nullification means making a law void by jury decision, in other words "the process whereby a jury in a criminal case effectively nullifies a law by acquitting a defendant regardless of the weight of evidence against him or her."

In the 17th and 18th centuries there were a series of cases starting in 1670 with the trial of the Quaker William Penn which asserted the (de facto) right of a jury to pass a verdict contrary to the facts or law. A good example is the case of one Carnegie of Finhaven who in 1728 accidentally killed the Scottish Earl of Strathmore. As the defendant had undoubtedly killed the Earl, the law (as it stood) required the jury to pass the verdict that the case had been "proven" and cause Carnegie of Finhaven to die for an accidental killing. Instead the jury asserted what it believed to be their "ancient right" to judge the whole case and not just the facts and brought in the verdict of "not guilty". This led to the development of the not proven verdict in Scots law.

Today in the United States, juries are instructed by the judge to follow his or her instructions concerning what is the "law", in his or her opinion, and to render a verdict solely on the evidence presented in court. If it reaches a conclusion contrary to those instructions, but based on its own beliefs as to what the law is, whether it has been properly applied, or whether it should be the law, this is known as jury nullification. It finds its most common expression when verdicts are rendered based on passion, prejudice, sympathy or bias. It has been asserted that the jury has the power to "nullify" a law it believes is unjust, by, for example, refusing to find the defendant guilty, in spite of the evidence, if it believes that a guilty verdict would be unjust. Important past exercises of this de facto power include cases involving slavery (see Fugitive Slave Act of 1850), freedom of the press (see John Peter Zenger), and freedom of religion (see William Penn).

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 seeks laws to force 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.
