Overview

Juries in the Federal Courts

Two things are the same in every federal district. The Federal Rules of Criminal Procedure say the jury must return its verdict to a judge in open court and that the verdict must be unanimous. They also set a jury of twelve, with fewer only when the parties agree in writing.

Jury instructions are different. The federal courts publish pattern instructions circuit by circuit, so the wording a jury hears depends on where the trial is held. The First Circuit's set tells jurors that they alone are the judges of the facts, and that they must follow the law whether they agree with it or not. What the printed comment to that instruction says is in the federal chapter of the guide.

The United States Constitution gives the accused a speedy and public trial by an impartial jury of the state and district where the crime was committed. It also says no person shall be put in jeopardy twice for the same offense. What that means for a verdict is in the chapter.

Your summons

Called for Jury Duty in the Federal Courts?

A federal jury summons comes from a United States district court. It asks you to come in and, if you are picked, to be one of twelve judges of the facts in a case.

The United States Courts have a Jury Service page. It covers reporting, who can serve, and how to ask to be excused, and it points to the court for your district.

That page covers serving. How federal jurors are drawn and questioned, what a pattern instruction says about the law, and what federal law does about anyone who tries to reach a juror are covered in the federal chapter of the guide.
