Grand Jury Summons: What to Expect
If you've received a summons to appear before the Marion County Grand Jury, this page will help you understand what that means and what happens next.
This is different from a typical jury. Most people are familiar with trial jury duty — sitting on a jury that hears a full trial and decides guilt or innocence. Grand Jury service is different. A Grand Jury is a group of citizens convened to review evidence before charges are filed, and to decide whether there is enough evidence to formally charge someone with a crime. A Grand Jury presentation is one of two ways to charge someone with a felony crim in Oregon. There is no judge present, likely no defense attorney, and no public audience. It is a separate process from the trials most people picture when they think of jury duty.
You may be summoned either to serve as a grand juror or to testify as a witness in a specific case — your summons will indicate which.
Frequently Asked Questions
How is this different from being on a trial jury?
Trial juries hear full criminal or civil trials, weigh evidence from both sides, and reach a verdict. A Grand Jury does not determine guilt or innocence, rather it decides whether there is sufficient evidence to charge someone with a crime. Grand Jury sessions are also closed to the public, unlike most trials. Witnesses are often subpoenaed to provide evidence to a Grand Jyry for their consideration of charges.
Is my appearance mandatory?
Yes. A Grand Jury summons is a legal order from the court. Failing to appear can result in penalties. If you have a scheduling conflict or hardship, contact the court if you're a grand juror and our office if you're a witness — do not simply skip the appearance.
What should I bring?
Bring your summons and a valid photo ID. If you were asked to bring specific documents or records, bring those as well.
Where and when do I go?
Your summons will list the date, time, and location. Plan to arrive early to allow time for security screening.
How long will it take?
This varies. Marion County operates a Grand Jury that meets either Monday/Wednesday/Friday or Tuesday/Thursday over a two-week term, from 9a.m.-5p.m. with an hour for lunch. Witnesses are typically asked to testify briefly on a specific date, though wait times can occur.
Will I be paid or reimbursed?
Jurors may receive mileage reimbursement.
Is Grand Jury testimony public?
No. Grand Jury proceedings are confidential by law. Jurors and witnesses are expected to keep what is discussed in the proceeding confidential.
