Discovery in Oregon runs on two separate tracks. Civil cases follow the Oregon Rules of Civil Procedure, specifically ORCP 36 through 46. Criminal prosecutions follow ORS 135.805 through 135.873. Each track sets out what the parties must share before trial, what tools they can use to pry information loose, and what a judge can do when someone refuses to cooperate. The Oregon discovery rules differ from federal practice in a few ways that matter, including the absence of any standalone written-interrogatory procedure on the civil side.
What Civil Discovery Reaches
ORCP 36B(1) sets the scope. A party can seek any non-privileged matter relevant to any party’s claim or defense, including the existence, description, and location of documents, tangible things, and people with knowledge of discoverable facts. The information doesn’t have to be admissible at trial. It only needs to appear “reasonably calculated to lead to the discovery of admissible evidence.”1OregonLaws. ORCP 36 – General Provisions Governing Discovery
One contrast with federal court is worth flagging. Federal Rule 26(b)(1) requires discovery to be “proportional to the needs of the case,” weighing things like the amount in controversy and the burden of production. Oregon’s ORCP 36B(1) has no explicit proportionality test. It uses the broader “reasonably calculated” standard instead. Oregon judges can still rein in overbroad requests through protective orders, but the front-end scope is wider than what federal practitioners are used to.
The Civil Discovery Tools
Requests for Production of Documents
ORCP 43 does most of the work in Oregon civil discovery. A party can serve a request demanding that another party produce documents, electronically stored information, or tangible things for inspection and copying, so long as the items fall within ORCP 36B and are in the other party’s possession or control. Each request must describe the items with “reasonable particularity” and designate a reasonable place and manner for the inspection. The responding party generally has 30 days to serve a written response, unless the court orders otherwise or the parties agree to a different timeline.2Oregon State Legislature. Oregon Rules of Civil Procedure – Section: Production of Documents and Things
The rule reaches electronically stored information, and it accounts for the practical mess digital evidence creates. When a request for electronically stored information is anticipated, any party can request a meeting to discuss production scope, data sources, format, cost, search terms, preservation, privilege issues, and metadata. These conferences must happen within 21 days of the request. A court can hold a party’s failure to participate in good faith against them when ruling on later motions to compel or for protective orders.
There is also a continuing duty most people forget about. Under ORCP 43B(4), a party who responded to a production request must promptly produce any responsive item that later comes into that party’s possession or control, as long as the original request wasn’t objected to. If you receive a relevant document six months into the case, you hand it over without waiting for another request.
Depositions
ORCP 39 governs depositions, which let attorneys question witnesses under oath before trial. A court reporter records the testimony, and it can later be used to challenge a witness’s credibility at trial or as direct evidence if the witness becomes unavailable. Depositions can be taken orally or through written questions, though oral is far more common.3Oregon State Legislature. Oregon Rules of Civil Procedure – Section: Depositions Upon Oral Examination
Anyone can be deposed: expert witnesses, opposing parties, and people who aren’t involved in the case at all. The party scheduling the deposition must give notice specifying date, time, and location. For depositions of corporations and other organizations, ORCP 39C(6) lets the requesting party describe the topics to be covered, and the organization must then designate someone knowledgeable to testify on those subjects. Remote depositions are allowed under ORCP 39C(7) by stipulation or court order, and the oath can be administered in person or over the telephone. If the other side objects to a remote deposition, you’ll need a court order.
Physical and Mental Examinations
When a party’s physical or mental condition is genuinely at issue, the court can order that person to submit to an examination by a physician or psychologist under ORCP 44. This comes up most often in personal injury cases where the defendant wants an independent medical evaluation of the plaintiff’s claimed injuries.4OregonLaws. ORCP 44 – Physical and Mental Examination of Persons; Reports of Examinations
The court only orders an examination on a motion showing good cause, and the order must specify time, place, scope, and examiner. No party can demand one unilaterally. Under ORCP 44C, a plaintiff must deliver to the defendant, on request, copies of all written reports from examining experts related to the injuries at issue. Oregon courts have excluded expert testimony when a party failed to produce the expert’s report.
Subpoenas to Non-Parties
When you need documents or testimony from someone who isn’t a party, you use a subpoena under ORCP 55. A subpoena can command a person to appear and testify, produce documents for inspection, or both. Subpoenas issue from the court where the action is pending and can be issued by an attorney of record or the court clerk.5Oregon State Legislature. Oregon Rules of Civil Procedure – Section: Subpoena
When a subpoena commands production before a deposition, hearing, or trial, tighter timing rules apply. The subpoena must be served on all non-defaulting parties at least 7 days before it is served on the non-party, unless the court shortens that period. The non-party must be given at least 14 days to produce the requested items. And the subpoena must specify whether originals or true copies will satisfy the request. For subpoenas seeking confidential health information, the notice period is longer: the serving party must serve a copy on the person whose health records are sought at least 14 days before serving the subpoena on the records custodian.
A person who receives a subpoena they consider unreasonable or oppressive can file a motion to quash or modify it. The motion must be filed with the court and served on the issuing party before the date set for appearance or production, and no more than 14 days after the subpoena was served. If the court agrees, it can quash or modify the subpoena, or require the serving party to cover the reasonable costs of compliance.
What Oregon Civil Discovery Doesn’t Include
If you’re used to federal court or another state, you might expect a dedicated written-interrogatory procedure. Oregon doesn’t have one. Unlike Federal Rule of Civil Procedure 33, which allows parties to serve up to 25 written questions answered under oath, the Oregon rules contain no standalone interrogatory rule. Oregon practitioners rely on depositions, production requests, requests for admission under ORCP 45, and the general discovery authority of ORCP 36 to gather what interrogatories would otherwise pull in.
The Oregon Supreme Court’s decision in Stevens v. Czerniak, 336 Or 392 (2004), sharpens the point. The court held that ORCP 36 does not authorize pretrial disclosure of expert witnesses’ identities or the substance of their expected testimony, because no specific rule provision grants that authority. Oregon discovery tools are powerful, but they are bounded, and courts won’t stretch them beyond what the rules say.
What the Prosecution Must Disclose in Criminal Cases
Criminal discovery runs on a different set of statutes. ORS 135.805 through 135.873 apply to all criminal prosecutions where charges have been brought in a court of record.6Oregon State Legislature. Oregon Revised Statutes 135.805 – Applicability; Scope of Disclosure The obligations run in both directions, but the prosecution’s list is longer.
Under ORS 135.815, the district attorney must turn over the following to a represented defendant:
- Names, addresses, phone numbers, and any written or recorded statements of witnesses the prosecution intends to call at trial.
- Any written or recorded statements made by the defendant, or by a codefendant in a joint trial.
- Reports or statements from experts, including results of physical or mental examinations, scientific tests, and comparisons the prosecution plans to introduce.
- Books, papers, photographs, and tangible objects the prosecution intends to offer at trial or that were obtained from or belong to the defendant.
- Any known prior convictions of prosecution witnesses.
- Prior convictions of the defendant that would affect sentencing under Oregon Criminal Justice Commission rules.
- Any information that tends to exculpate the defendant, negate or mitigate guilt or punishment, or impeach a prosecution witness.
The exculpatory disclosure obligation under ORS 135.815(1)(g) is the one to pay attention to. It applies whether or not the material is in writing, and it must happen without delay. If the prosecution discovers exculpatory information after the defendant has already entered a guilty plea, it must still disclose promptly.7OregonLaws. ORS 135.815 – Disclosure to Defendant This tracks the constitutional requirement from Brady v. Maryland, 373 U.S. 83 (1963), which requires prosecutors to disclose material evidence favorable to the defense.
What the Defense Must Disclose
Discovery isn’t one-sided. Under ORS 135.835, the defense must disclose to the district attorney:
- Names and addresses of defense witnesses, including the defendant, along with relevant written or recorded statements. The defendant’s own statements are excluded from this requirement.
- Reports from defense experts, including results of examinations, tests, and comparisons the defense plans to introduce at trial.
- Any items the defense intends to offer as evidence at trial.
The defense obligation is narrower than the prosecution’s. The defense only has to disclose materials it actually intends to use at trial, and there is no equivalent to the prosecution’s obligation to turn over all exculpatory information.8OregonLaws. ORS 135.835 – Disclosure to the State Both sides’ duties are subject to exceptions under ORS 135.855, which exempts certain categories of material from discovery, and ORS 135.873, which allows protective orders.
What Discovery Can’t Touch: Privilege and Work Product
Not everything is discoverable. Oregon recognizes several privileges, and the two that come up most in discovery disputes are attorney-client privilege and work product protection.
Attorney-Client Privilege
Under ORS 40.225, a client can refuse to disclose confidential communications made for the purpose of obtaining or providing professional legal services. The privilege covers communications between the client (or the client’s representative) and the attorney, between the attorney and the attorney’s staff, and between attorneys representing the same client.9Oregon State Legislature. Oregon Revised Statutes 40.225 – Rule 503, Law Practitioner-Client Privilege A confidential communication means one not intended to be disclosed to third parties, except people involved in providing legal services or necessary to transmit the communication.
The privilege belongs to the client, not the attorney. The client can waive it, and accidental disclosure to third parties can destroy it. Share privileged communications with someone outside the legal representation and a court may find the privilege no longer applies.
Work Product
ORCP 36B(3) protects trial preparation materials — documents and tangible things prepared in anticipation of litigation by or for a party or that party’s representative, including attorneys, consultants, and insurers. The opposing party can only obtain them by showing substantial need and an inability to get the equivalent information through other means without undue hardship.
Even when a court orders disclosure of trial preparation materials, it must protect the attorney’s mental impressions, conclusions, opinions, and legal theories. This “opinion work product” receives near-absolute protection. A factual investigation memo prepared for litigation might be discoverable with the right showing. The attorney’s strategic analysis of that investigation almost never is.
When you withhold documents based on privilege or work product, you need to identify them for the other side so they can challenge the claim. Oregon state courts don’t prescribe a single format for a privilege log, but the practice mirrors federal expectations: enough information for the opposing party and the court to evaluate the claim without revealing the protected content itself.
When a Request Goes Too Far: Protective Orders
When a discovery request is oppressive, embarrassing, or too expensive relative to what it would produce, the targeted party can seek a protective order under ORCP 36C. The court has a wide range of options, including prohibiting the discovery entirely, allowing it only on specified terms, limiting the scope to certain topics, restricting who may be present, requiring trade secrets or confidential business information to be disclosed only in a designated way, and ordering the requesting party to pay the responding party’s reasonable expenses.
The moving party must show good cause. Broad claims of harm won’t cut it. You need to identify specific prejudice that will result without the order. Protective orders come up often in cases involving trade secrets, proprietary financial data, and sensitive medical or personal records. Violating one can trigger sanctions.
Confer First, Then Move
Before filing any motion under ORCP 36 through 46, including a motion to compel discovery, the moving party must first make a good faith effort to resolve the dispute with the other side. Uniform Trial Court Rule 5.010 requires a certificate of compliance filed with the motion, stating either that the parties conferred or explaining good cause for not doing so. Without it, the motion will be denied.10Oregon Judicial Department. Uniform Trial Court Rules – Section: UTCR 5.010
Skipping conferral is the fastest way to lose a discovery motion without the judge reaching the merits. Most disputes settle with a phone call or email exchange, and courts expect litigants to try that first. If conferral fails, the effort itself demonstrates reasonableness when the judge takes up the issue.
What Happens When Someone Refuses to Cooperate
ORCP 46 gives judges real power. When a party disobeys a discovery order, the court can order that disputed facts be treated as established in favor of the party who sought the discovery. It can prohibit the disobedient party from supporting or opposing designated claims, or from introducing specific evidence. It can strike parts of the offending party’s case, dismiss the action, or enter a default judgment. And it can treat the failure as contempt of court.
On top of any of these, the court must also order the noncompliant party or their attorney (or both) to pay the other side’s reasonable expenses, including attorney fees, unless the failure was substantially justified or the circumstances make an award unjust.11OregonLaws. ORCP 46 – Failure to Make Discovery; Sanctions
The same penalties apply when a party fails to attend their own deposition or respond to a production request. Deliberate destruction of evidence, sometimes called spoliation, can result in orders establishing that the missing evidence would have been unfavorable, which is often case-ending in practice. In criminal cases, a prosecutor’s failure to disclose exculpatory material under ORS 135.815 can lead to overturned convictions. Oregon courts treat discovery obligations as commands, not suggestions.
