The Oregon Court Process: A Step-by-Step Guide for Defendants and Families

A step-by-step guide to the Oregon criminal court process, from arrest and initial appearance through grand jury, trial, sentencing, and appeal.

If you or someone you love is facing criminal charges in Oregon, the court process offers three different paths a felony charge can take before it reaches arraignment, and the sentencing structure has two layers that both families and defendants need to understand: the grid-based sentencing guidelines and, for certain serious offenses, the mandatory minimums imposed by Ballot Measure 11. I have been through the system myself, and most of the fear comes from not knowing what each step is for. So let me walk you through the Oregon criminal court process one stage at a time, in plain language. None of this is legal advice, and every case and county is different, so treat it as a map and lean on a lawyer for the turns.

Start with how Oregon organizes its courts. Oregon has a single tier of general trial courts called circuit courts, covering all 36 counties across 27 judicial districts. There is no separate lower court for initial appearances in most counties; the circuit court handles everything. Above the circuit courts sits the Oregon Court of Appeals, the intermediate appellate court, and above that the Oregon Supreme Court.

Step one: arrest and the initial appearance

It begins with arrest and booking, where the charges are recorded, fingerprints and a photo are taken, and the jail runs its checks. The State of Oregon, represented by the district attorney, brings the case. The accused is the defendant, and the defense attorney represents them. After arrest the defendant is brought before a judge for an initial appearance, where the charges are reviewed, release conditions are set, and counsel is appointed if the defendant cannot afford one. Oregon uses a risk-based pretrial release system rather than a pure cash bail system, and the court sets conditions aimed at ensuring the defendant returns to court and does not pose a danger to the community.

Step two: three paths to formal charge

Oregon's Constitution requires that before a felony prosecution moves forward, the defendant must either have the charge reviewed by a grand jury or have a preliminary hearing, unless those rights are waived. This gives Oregon three charging paths for felonies.

The first path is a grand jury indictment. A grand jury in Oregon has seven members, and at least five must agree to indict. The proceedings are closed. The defendant does not attend and the defense does not present evidence. The grand jury hears evidence from the district attorney and decides whether there is probable cause to formally charge the defendant. If five or more grand jurors agree, they return an indictment and the case moves to arraignment in circuit court.

The second path is a preliminary hearing followed by a district attorney's information. At a preliminary hearing, the judge determines whether there is probable cause to believe that the crime was committed and that the defendant committed it. If the judge finds probable cause, the district attorney then files an information, a written charging document, and the case proceeds to arraignment. If sufficient evidence is not presented, the defendant is discharged.

The third path is a waiver. The defendant may voluntarily waive both the grand jury and the preliminary hearing and agree to the filing of a district attorney's information directly. This path moves the case forward most quickly and is sometimes chosen as part of a negotiated resolution or when the defendant has strategic reasons to proceed without a preliminary hearing. The preliminary hearing, if held, is an adversarial proceeding that gives the defense a real opportunity to cross-examine witnesses under oath before trial. Defense lawyers who anticipate a contested trial often recommend holding the preliminary hearing because the testimony that comes out can be used at trial if witnesses later change their story.

Step three: arraignment in circuit court

After a grand jury indictment, a preliminary hearing and information, or a direct information on waiver, the defendant is arraigned in circuit court. The court reads the accusatory instrument, which contains the charge, and the defendant is given a copy. The court ensures the defendant has or can obtain counsel, and the defendant enters a plea: guilty, not guilty, or no contest. Most defendants plead not guilty at this stage, which is the normal, expected move that preserves every right and forces the State to prove its case.

Step four: pretrial, discovery, and motions

After arraignment the case enters the pretrial phase. Both sides exchange evidence through discovery, including police reports, witness statements, lab results, and other materials. The defense can file pretrial motions, including a motion to suppress evidence obtained through an unlawful search. A successful suppression motion can fundamentally change the course of a case. Courts hold status conferences and motion hearings to manage the case schedule. Most Oregon felony cases are resolved through plea agreements rather than trial. Whether to accept a plea is entirely the defendant's decision. A good lawyer lays out the real risks and the real options so the defendant can choose with clear eyes. There is no shame in choosing to fight or in choosing a resolution that protects your future, as long as the choice is informed.

Step five: trial in circuit court

If the case does not resolve, it goes to trial in circuit court. A felony defendant has the right to a jury of twelve. A misdemeanor jury has six members and requires a unanimous verdict. Trial moves through jury selection, then opening statements, the State's case, the defense case, closing arguments, and the verdict. The State must prove guilt beyond a reasonable doubt. The defendant does not have to prove innocence and does not have to testify.

Step six: sentencing under Oregon's guidelines and Ballot Measure 11

If there is a guilty verdict or plea, the case moves to sentencing. Oregon uses a grid-based sentencing guidelines system established in 1989. At the center of the guidelines is a chart. Each crime is given a crime seriousness score, and each defendant is given a criminal history score based on prior convictions. Where those two scores intersect on the grid determines the presumptive sentence. The judge can depart upward or downward from the presumptive sentence based on aggravating or mitigating factors, but the guidelines constrain the range. Oregon's guidelines produce determinate sentences; the release date can be calculated from the sentence minus good-time credits earned for good behavior.

Ballot Measure 11, passed by Oregon voters in 1994 with a two-thirds majority and reaffirmed in 2000, operates over the grid and fundamentally changes sentencing for certain serious offenses. For approximately 25 violent crimes and serious sex offenses covered by Measure 11, the judge has no discretion and must impose a mandatory minimum prison sentence, regardless of the defendant's criminal history and regardless of what the guidelines grid would produce. Measure 11 mandatory minimums range from 70 months to 300 months in prison. Defendants convicted of Measure 11 offenses are not eligible for early release, good-time credits, or parole before completing the mandatory minimum. The result is that a Measure 11 sentence is exactly what it sounds like: you serve the full minimum. Examples of Measure 11 crimes include first-degree murder, first-degree rape, first-degree robbery, first-degree assault, first-degree arson, kidnapping, and compelling prostitution. There are narrow escape clauses for certain specific circumstances on a few of the covered offenses, but the general rule is that Measure 11 is absolute. For families, this distinction between a Measure 11 and a non-Measure 11 offense is often the most consequential thing to understand because it determines whether any of the flexibility built into the sentencing guidelines exists at all.

Before sentencing, a presentence investigation report may be ordered. Victims have the right to submit impact statements and to address the court.

Step seven: appeals

A conviction is not always the end of the road. Most felony convictions from circuit court are appealed to the Oregon Court of Appeals, the intermediate appellate court. The Court of Appeals reviews the record for legal errors. From the Court of Appeals, a party may seek review by the Oregon Supreme Court, which has discretionary jurisdiction. Deadlines run quickly after sentencing, so anyone considering an appeal needs to tell their lawyer right away.

A cursory look at the federal court process in Oregon

Everything above describes the Oregon state court system, which handles the overwhelming majority of criminal cases. Some cases, though, are charged as federal crimes and move through an entirely separate system worth understanding in outline.

The entire state forms a single federal trial district, the United States District Court for the District of Oregon. The court has four courthouse locations. The main courthouse is the Mark O. Hatfield United States Courthouse in Portland, named for the longtime U.S. Senator from Oregon. Additional proceedings are held at the Wayne Lyman Morse United States Courthouse in Eugene, the James A. Redden United States Courthouse in Medford, and the John F. Kilkenny United States Courthouse in Pendleton. A federal case in Oregon is prosecuted by the United States Attorney's Office for the District of Oregon, not by a county district attorney, and it is heard by federal judges in those courthouses.

The federal sequence covers the same broad ground you read about above but with its own rules and players. After a federal arrest, the defendant has an initial appearance before a United States magistrate judge, with detention or release decided under the federal Bail Reform Act rather than Oregon's risk-based pretrial conditions. There is no state preliminary hearing or grand jury Oregon constitutional requirement in the federal system. Federal felony charges are brought by indictment from a federal grand jury. The case proceeds through arraignment, discovery and motions, and either a plea or a trial in United States District Court. Federal sentences are calculated under the United States Sentencing Guidelines, which differ from Oregon's grid-based guidelines; federal sentences carry mandatory minimums in many cases, are served in federal prison, and there is no parole in the federal system.

If a federal case in Oregon ends in conviction and is appealed, it does not go to the Oregon Court of Appeals or the Oregon Supreme Court. It goes to the United States Court of Appeals for the Ninth Circuit, headquartered in San Francisco. The Ninth Circuit also maintains a courthouse in Portland close to the Hatfield Courthouse, where most Oregon federal appeals are actually heard. From the Ninth Circuit the only further step is the United States Supreme Court. Because federal practice is its own world, anyone facing a federal charge in Oregon should make sure their lawyer has real federal court experience.

Where this leaves you

The Oregon court process has two things that families most need to understand before everything else: which of the three charging paths is being used, because that determines how quickly the case moves to arraignment, and whether the offense is a Measure 11 crime, because if it is, the sentence the judge says in court is the sentence that will be served, with no early release and no parole. Knowing the sequence, initial appearance, charging path, arraignment, pretrial, plea or trial, sentencing under the guidelines or Measure 11, and appeal, lets you see where your person is instead of feeling lost in it. Get a lawyer involved as early as you can, keep one page with the charges, the court, the next date, and your attorney's contact information, and stay close to your loved one through it. The system is built to make people feel alone. Knowing the map is how you push back against that.
