Pennsylvania Jury Practice

PA Jury Practice

Most court cases do not result in a jury trial. According to the Administrative Office of Pennsylvania Courts, in 2017 approximately 2,600 of the 422,000 processed civil and criminal cases were decided by a jury in the common pleas courts of Pennsylvania. Though jury practice is not common, there are resources to help those who decide to have their cases tried by a jury.

This guide highlights the sources available at Jenkins on Jury Practice in Pennsylvania. The resources include sources available to Jenkins' members freely online, on member databases, or in the library. Onsite Lexis and Westlaw access is noted when available.

Key Terms & Definitions

The following key terms are useful to know when engaging in jury practice.

Grand Jury: "A grand jury is a body of men and women selected and summoned to serve before a competent court and charged to inquire with regard to crimes committed within its jurisdiction and to present all offenders against the law. The grand jury has an ancient role in determining if there is probable cause to believe that a crime has been committed and a related responsibility of protecting citizens against unfounded criminal prosecutions. It is an inquisitorial and accusatorial, rather than a trial, body." 38A C.J.S. Grand Juries § 1 (2019).

Jury Instructions: "Most jurisdictions have published sets of model or pattern jury instructions, used by judges to explain the applicable law to jurors. Model jury instructions are useful in research because they provide a concise summary of a jurisdiction's law on the issues covered, often accompanied by notes summarizing the leading cases." Morris L. Cohen & Kent C. Olson, Legal Research in a Nutshell § 7-6, at 205 (13th ed. 2018).

Jury Verdict: "The decision of the issues in an action which a jury orally announces to the court, and which is received and recorded at the direction of the court, is the verdict of the jury." 50 Pennsylvania Law Encyclopedia Trial § 381 (2nd ed. 2015).

Voir Dire: "Voir dire is the process by which the court and the lawyers first question jurors and then decide which members of the jury pool will hear a particular case. Although often described as a process of jury selection, voir dire is in fact a process of de-selection in which lawyers seek to identify the least suitable jurors for the case and then have these jurors either struck for cause or excused through a peremptory challenge." James J. Gobert et al., Jury Selection: The Law, Art and Science of Selecting a Jury § 10.1 (3rd ed. 2016-2017).
