Overview

Juries in Pennsylvania

Pennsylvania's constitution speaks to the jury and the law in its section on the press. In all indictments for libels the jury shall have the right to determine the law and the facts, under the direction of the court, as in other cases. The official text prints a note beside that section on the constitutionality of its criminal libel provisions.

Before a trial, every prospective juror fills in a statewide questionnaire, and one of its questions asks whether they would have any problem following and applying the judge's instruction on the law. For other trials, the wording a Pennsylvania jury hears is in the standard instructions, which are published by the Pennsylvania Bar Institute. The court rules say when a jury is instructed and what the first instructions should cover. What they list is in the Pennsylvania chapter of the guide.

A Pennsylvania court rule says the verdict shall be unanimous and announced in open court. Any party can ask for the jury to be polled before it is recorded. What happens when a juror does not concur is in the chapter.

Your summons

Called for Jury Duty in Pennsylvania?

A Pennsylvania jury summons asks you to come to court. Under the court rules, jury service starts when you join the group that jurors are picked from, and your first instructions come when you arrive.

The Pennsylvania courts have a Jury Duty page. It covers reporting, who can serve, and how to ask to be excused.

That page covers serving. What you are told on arrival and what you may not look up, what the constitution says about the jury in libel cases, and how a verdict is announced and polled are covered in the Pennsylvania chapter of the guide.
