MassachusettsJury Nullification

In Massachusetts a model instruction tells jurors to follow the law as the judge gives it, whether they agree with it or not. The judge rules on the evidence and instructs on the law, and the jury decides the case. A court rule requires a unanimous verdict. The state constitution says no one loses life, liberty or property except by the judgment of their peers or the law of the land.

Overview

Juries in Massachusetts

The Massachusetts model instruction on the judge's role says it directly. Jurors must follow the law as the judge gives it, whether they agree with it or not. A court rule requires the verdict to be unanimous, and a second instruction says that holds for a verdict of guilty or of not guilty.

The same instruction tells jurors how to treat the instructions as a set. It names two things a juror must not do with them. What those are is in the Massachusetts chapter of the guide.

The Massachusetts constitution protects a person accused of a crime with the words the judgment of his peers, or the law of the land. What the rest of that article says, and which jury article covers civil disputes, is in the chapter.

Your summons

Called for Jury Duty in Massachusetts?

A Massachusetts jury summons asks you to come to court and, if you are picked, to decide a case on the evidence. The judge rules on the evidence and gives you the law.

The state's Jury Duty page covers reporting, who can serve, and how to ask to be excused.

That page covers serving. What the model instruction says about the law, how a unanimous verdict is reached and polled, and how state law protects jurors and their families are covered in the Massachusetts chapter of the guide.
