OregonJury Nullification

In Oregon a statute makes jurors the judges of the effect or value of the evidence, subject to the control of the court. The same statute has the judge tell them that this power is not arbitrary. The state constitution says that in all criminal cases the jury has the right to determine the law, and the facts under the direction of the court as to the law. State law sets a jury of twelve. A jury can return a verdict of guilty only by unanimous agreement, and a verdict of not guilty by at least ten of the twelve.

Overview

Juries in Oregon

Oregon's statute makes the jury the judges of the effect or value of the evidence, subject to the control of the court. It also has the judge tell jurors that this power is not arbitrary and is to be used with legal discretion, within the rules of evidence.

Oregon sets two numbers for a verdict in back to back lines of one statute. A jury can find a person guilty only by unanimous agreement. It can find a person not guilty when at least ten of the twelve agree. What the Oregon constitution says on the same subject, in its own words, is in the Oregon chapter of the guide.

That statute has one more thing to say about witnesses, and about how many of them it takes to bind a jury. What it says is in the chapter.

Your summons

Called for Jury Duty in Oregon?

An Oregon jury summons asks you to come to court and, if you are picked, to weigh the evidence in a case as one of twelve jurors.

The Oregon Judicial Department has a Find Juror Information page. It covers reporting, who can serve, and how to ask to be excused.

That page covers serving. What the judge has to tell you about weighing evidence, how many jurors it takes for each verdict, and how Oregon law treats a juror as a public servant are covered in the Oregon chapter of the guide.

Oregon asks for every juror to convict and for ten of twelve to acquit, and both numbers sit in one statute. This page gives you the numbers. What the constitution says beside them, what the judge has to tell you about your power over the evidence, and what the law says about anyone who offers a juror a benefit are in the Oregon chapter.
