Jury Nullification Appeals

What it is

Argument, explicit or veiled, that asks jurors to acquit because the law or its application is unjust rather than because the evidence fails, drawing on the jury's unreviewable power to return a general verdict of not guilty.

How it works

A criminal jury's acquittal is final and unexplained; jurors cannot be punished for their verdict (Bushel's Case, 1670), and no judge may direct a verdict of guilty. That combination gives juries the power to nullify. American courts have long held that the power is not a right: Sparf v. United States (1895) ruled that jurors need not be told they may disregard the law, and United States v. Dougherty (1972) refused a nullification instruction while acknowledging the power exists. Explicit appeals ("you can send a message that this law is wrong") are prohibited in nearly every US court and can draw a mistrial or contempt; veiled forms, such as "conscience of the community" rhetoric or emphasis on the harshness of the penalty, are policed unevenly. The history is two-sided. Juries refused to convict under the Fugitive Slave Act and Prohibition; all-white juries also acquitted the two men who later confessed to killing Emmett Till. The persuasion works through moral identity and reactance: the juror is invited to see the verdict as an act of conscience against an unjust system.

Real-world examples

  • Bushel's Case (1670): after jurors acquitted William Penn of unlawful assembly and were jailed for it, the Court of Common Pleas held that jurors may not be punished for their verdict, the foundation of the jury's independence.
  • The 1735 acquittal of John Peter Zenger for seditious libel, against the court's position that truth was no defense, is the celebrated American example; juries in the 1850s likewise refused to convict under the Fugitive Slave Act.
  • In 1955 an all-white Mississippi jury acquitted Roy Bryant and J. W. Milam of murdering Emmett Till after about an hour of deliberation; the two confessed to the killing in a magazine interview the following year, protected by double jeopardy.
  • Jack Kevorkian was acquitted three times in the mid-1990s in assisted-suicide prosecutions by juries that plainly disagreed with the law; he was convicted of second-degree murder in 1999 after administering a lethal injection himself on videotape.
  • Sparf v. United States (1895) and United States v. Dougherty (1972) fix the American rule: jurors have the power but no right to be told of it, and lawyers may not argue for it.

Ethical guidelines

Where the line is

Arguing that the prosecution has not proved its case, and appealing to the jury's duty to require proof beyond a reasonable doubt, is legitimate however forcefully it is put; asking jurors to disregard the law or the instructions, to acquit because the penalty is harsh, or to send a message about the statute converts the fact-finder into a political actor and is prohibited in nearly every US court.

  • Arguing that the evidence does not prove the elements, and arguing reasonable doubt with full force, is always permitted; that is not nullification.
  • Explicitly asking jurors to disregard the law or the instructions, or telling them they have a "right" to nullify, is prohibited in nearly every US jurisdiction and exposes counsel to contempt and discipline; the ethical rules require candor about the law (Model Rule 3.3).
  • The power belongs to the jury, not to the advocate; a lawyer who manipulates it is using the fact-finder's conscience as a tactic, and the history shows the same power that protected Zenger shielded Till's killers.
  • Educational; rules vary by jurisdiction; not legal advice.

How to defend against it

  • Jurors: the oath binds you to the law as instructed; if you find yourself persuaded that the law is unjust rather than that the evidence is insufficient, recognize the distinction, and understand that announcing an intent to disregard the instructions can lead to your removal from the jury.
  • Jurors: separate the harshness of a penalty from the sufficiency of the proof; in most courts you will not be told the sentence, precisely so that it cannot drive the verdict.
  • Opposing advocates: object to arguments that invite decision on the justice of the law or the severity of punishment, and ask for the standard instruction that the jury must apply the law whether or not it agrees with it.
  • Citizens: the debate over nullification is a legitimate political one, conducted outside the jury room through legislation and public argument; organizations on both left and right have championed it, and the courtroom is the one place the rules keep it out.
