State v. Driver: Mandamus Denied, Leaving Remedies for Prohibited Grand Jury Hearsay Unresolved

Supreme Court of Oregon, en banc — 375 Or 728 — October 8, 2026

1. Introduction

State v. Driver presents a fundamental question about the enforcement of Oregon’s restrictions on grand jury evidence: if prosecutors obtain an indictment using statutorily prohibited hearsay, does a trial court have authority to provide a remedy beyond the grounds expressly identified in Oregon’s indictment-dismissal statute?

The Supreme Court did not answer that question. Its per curiam decision denied Zackery Max Driver’s petition for a writ of mandamus without substantive analysis. Justice James, joined by Justice Masih, dissented because he believed the court should accept the proceeding to clarify trial courts’ authority.

The distinction between the disposition and the dissent is essential. The decision establishes no new substantive rule authorizing dismissal, prohibiting dismissal, or permitting the challenged hearsay. Its significance lies in leaving existing precedent undisturbed while exposing, through the dissent, an unresolved tension between a mandatory evidentiary prohibition and potentially restrictive remedial rules.

Parties and factual background

The State of Oregon obtained a grand jury indictment against Driver on October 27, 2025. The charges included 25 counts of promoting prostitution. According to the indictment, a police officer was the grand jury’s only witness; none of the alleged victims testified.

Driver alleged that the officer conveyed out-of-court statements from multiple alleged victims in violation of ORS 132.320(7)(a). That statute provides that “inadmissible hearsay of persons other than the peace officer who compiled the official report may not be presented to a grand jury.” The state did not dispute that the officer related those statements, but disputed their characterization as inadmissible hearsay, arguing that they either were not hearsay or fell within an exception.

Thus, the record did not establish a judicial finding that the indictment rested on prohibited evidence. The dispute concerned both whether a violation occurred and whether an effective remedy would be available if it did.

Procedural background

  1. Requested relief: Driver did not expressly ask the circuit court to set aside the indictment. Instead, he requested a preliminary hearing to determine probable cause. Justice James suggested that Driver likely chose that approach because existing precedent appeared to foreclose dismissal for improper hearsay.
  2. Requested examination of the record: Driver asked the court to review the grand jury transcripts in camera to determine whether prohibited hearsay had been presented.
  3. Constitutional objection: Driver argued that, if ORS 132.270(7)(b) prevented him from using the transcripts to establish the violation, that restriction violated the remedies clause of Article I, section 10, of the Oregon Constitution.
  4. State’s response: The state characterized the request as an impermissible challenge to the indictment, notwithstanding its preliminary-hearing label. It also argued that there could be no good cause for judicial examination of the transcripts if no remedy was legally available.
  5. Circuit court ruling: The court denied the motion, finding no good cause for the requested use of the transcripts, declining to hold the statute unconstitutional, and finding no grounds to set aside the indictment. The transcript was received as an offer of proof, but the court declined the requested examination for the purpose of challenging the indictment.
  6. Supreme Court proceeding: Driver timely sought mandamus relief. The Supreme Court denied his petition.

Driver alternatively requested release from custody, but did not develop that argument. The opinion also identifies a typographical error in the circuit court’s order: the challenged transcript statute was ORS 132.270, not ORS 132.370.

2. Summary of the Opinion

The court’s disposition

The controlling decision consists of a denial of the mandamus petition. It does not explain the court’s reasons, resolve the admissibility of the officer’s testimony, decide the constitutional challenge, or determine whether circuit courts possess inherent authority to remedy a violation of ORS 132.320(7)(a).

The court’s footnote expressly warns that separate opinions do not indicate how the court as a whole would decide an issue in a future case and are not an invitation from the court to pursue the arguments they discuss.

Justice James’s dissent

Justice James accepted that mandamus is extraordinary and discretionary, and acknowledged imperfections in Driver’s case. Nevertheless, he would have issued an alternative writ so that the court could receive briefing and argument about trial courts’ remedial authority.

His principal concerns were:

  • Oregon’s legislature deliberately prohibits specified inadmissible hearsay before grand juries.
  • Existing decisions interpreting ORS 135.510 as providing exclusive grounds for setting aside indictments may leave courts uncertain whether they can enforce that prohibition.
  • Those decisions may not have considered a separate source of authority: courts’ inherent supervisory power over grand juries.
  • The statute’s mandatory language might identify circumstances requiring dismissal without eliminating discretionary dismissal on other legally sufficient grounds.
  • Ordinary appellate review may not effectively resolve the question after trial.

Importantly, the dissent did not conclude that Driver was entitled to dismissal, a preliminary hearing, or a final writ. It advocated consideration of the legal questions, while recognizing that the court might ultimately leave the circuit court’s ruling in place.

3. Statutory and Constitutional Framework

Provision Role in the dispute
ORS 132.320(7)(a) Restricts the presentation of inadmissible hearsay to grand juries. Whether the officer’s testimony violated this provision remained disputed.
OEC 101(4)(b) Generally excludes grand jury proceedings from much of the evidence code, but expressly preserves requirements imposed by ORS 132.320.
ORS 135.510 Requires courts to set aside indictments for specified defects involving their finding, endorsement, presentation, and identification of grand jury witnesses. Existing precedent describes those statutory grounds as exclusive.
ORS 132.270(2)(c) Restricts copying, dissemination, and republication of released grand jury recordings and transcripts, subject to a court order for good cause and specified case-preparation uses. Driver invoked its good-cause language in seeking judicial review.
ORS 132.270(7)(b) Provides that grand jury transcripts may not be used to challenge endorsement of an indictment as a “true bill” or the proceedings leading to endorsement.
Oregon Constitution, Article VII (Amended), section 5(5) Supplies the constitutional basis for a probable-cause preliminary hearing when prosecution proceeds by information. Driver sought such a hearing as relief for the allegedly defective indictment.
Oregon Constitution, Article I, section 10 Contains the remedies clause invoked by Driver against the transcript-use restriction. The Supreme Court did not adjudicate that challenge.

These provisions create distinct questions. Establishing that evidence was prohibited does not itself identify the remedy. Likewise, identifying a potentially available remedy does not automatically authorize use of otherwise restricted grand jury transcripts.

4. Analysis of the Precedents Cited

Except for the court’s citation concerning separate opinions, the precedents below appear in Justice James’s dissent. They inform his proposed inquiry, not an adopted merits analysis by the court.

A. The status of the dissent

State v. DeWitt Simons

The per curiam opinion cites State v. DeWitt Simons, 375 Or 70, 93 n 12 (2026), for the proposition that individual justices may express views in separate opinions, but those views neither predict the court’s future resolution nor constitute a court-sanctioned invitation to litigate them. This citation supplies an explicit interpretive limit: Justice James’s discussion cannot be treated as recognition of inherent dismissal authority.

B. Oregon’s grand jury function and hearsay restriction

State v. Burleson

State v. Burleson, 342 Or 697, 703 (2007), describes the grand jury as a body of ordinary citizens whose approval is required before the state initiates major criminal accusations. Its protective function is to restrain potential abuse of the accusatory process.

Justice James uses that characterization to explain why evidentiary safeguards matter before trial. A later determination of guilt or innocence does not necessarily eliminate the significance of an unlawfully initiated prosecution.

State v. McDonald

In State v. McDonald, 231 Or 24, 34 (1961), the court treated the grand jury evidence restriction as admonitory rather than mandatory. It reasoned that grand jurors are lay investigators, not judges deciding guilt, and doubted that the legislature intended strict compliance with trial admissibility rules.

Justice James contrasts that approach with the subsequent adoption of OEC 101(4)(b). The legislative commentary expressly disapproved the pertinent case law and stated that the legislature intended the statute to mean what it said. The dissent therefore treats the prohibition’s mandatory character as a deliberate legislative choice rather than a merely aspirational instruction.

The opinion does not, however, contain a new majority ruling formally reconsidering State v. McDonald. Its significance here is historical: it shows how the legislature responded to an earlier judicial narrowing of the restriction.

C. The asserted exclusivity of statutory dismissal grounds

State v. Stout

State v. Stout, 305 Or 34, 38 (1988), is the central obstacle to Driver’s position. It declared that the grounds in ORS 135.510 for setting aside an indictment are exclusive. Because improper hearsay was not among those grounds, the court refused to set aside the indictment.

That decision avoided resolving the effect of OEC 101(4)(b) on State v. McDonald. Instead, it shifted the inquiry from whether hearsay was prohibited to whether the legislature had supplied a dismissal remedy.

Justice James suggests that the exclusivity statement might be broader than necessary because the court was not asked to examine inherent supervisory authority. He therefore raises the possibility of distinguishing or limiting the decision. That is a proposed argument, not a determination that the exclusivity statement is nonbinding.

State v. Whitney

State v. Whitney, 7 Or 386, 388 (1879), supplied the foundation for the exclusivity proposition in State v. Stout. It interpreted an earlier criminal-code provision identifying two circumstances in which an indictment must be set aside and declared them the only permissible grounds.

The challenged defect involved an unauthorized person’s appearance before the grand jury. Because the relevant prohibition was outside the provisions incorporated into the dismissal statute, the court rejected relief.

Justice James emphasizes the brevity of that reasoning and the absence of an inquiry into inherent judicial authority. His concern is that a conclusion about what a statute authorizes may have become a broader conclusion about every possible source of judicial power.

D. Judicial supervision and its limits

State v. Wall

State v. Wall, 374 Or 407, 413–14 (2025), identifies the grand jury’s institutional connection to Oregon’s courts. Courts participate in selecting and excusing grand jurors, appointing forepersons, administering oaths, instructing grand juries, resolving legal questions, authorizing certain participants and evidence, and determining the duration of service.

For Justice James, those responsibilities support investigating whether supervision includes an inherent power to remedy unlawful evidentiary presentations. But the institutional relationship described in State v. Wall does not itself establish a dismissal remedy.

United States v. Hasting and McNabb v. United States

United States v. Hasting, 461 US 499, 505–06 (1983), quoting McNabb v. United States, 318 US 332, 341 (1943), recognizes that federal courts may, within limits and guided by considerations of justice, formulate procedural rules not expressly required by the Constitution or Congress.

The dissent identifies three purposes of supervisory authority discussed in United States v. Hasting: remedying violations of recognized rights, preserving judicial integrity, and deterring illegal conduct. These purposes offer an analogy for enforcing Oregon’s statutory grand jury safeguards.

The analogy remains conditional. Federal supervisory doctrine does not automatically establish the existence or scope of a corresponding Oregon power.

United States v. Williams

United States v. Williams, 504 US 36, 50 (1992), provides the counterweight: any federal judicial power to formulate grand jury procedural rules on the court’s own initiative is very limited.

Justice James acknowledges that limitation. His narrower suggestion is that enforcing an existing, explicit legislative prohibition may warrant consideration even where courts cannot freely create new grand jury procedures.

E. Statutory interpretation: mandatory does not necessarily mean exclusive

Bacote v. Johnson

Bacote v. Johnson, 333 Or 28, 33 (2001), states that “shall” expresses a mandatory command. Justice James uses that proposition to distinguish required action from the full range of permissible action: ORS 135.510 says when an indictment must be set aside, but does not expressly say those are the only circumstances in which it may be set aside.

Linn County v. Brown and AAA Oregon/Idaho Auto Source v. Dept. of Rev.

Linn County v. Brown, 366 Or 334, 342 (2020), citing AAA Oregon/Idaho Auto Source v. Dept. of Rev., 363 Or 411, 418 (2018), invokes the principle that courts should not insert omitted language or remove enacted language when interpreting statutes or constitutional provisions.

The dissent applies that principle to the missing word “only.” Reading ORS 135.510 as saying that an indictment “shall only be set aside” in its enumerated circumstances might, in his view, add a restriction the legislature did not express. Whether context and legislative purpose nevertheless support exclusivity remains unresolved.

Scott v. Ford

Scott v. Ford, 52 Or 288, 296 (1908), recognizes that a statute limiting an act to a particular form may implicitly prohibit other forms. This supports the interpretive maxim expressio unius est exclusio alterius: expressly identifying one thing can imply exclusion of others.

Justice James acknowledges that reasoning but questions whether it should control a provision specifying mandatory remedies without expressly eliminating discretionary authority.

Sunshine Dairy v. Peterson and Cabell v. City of Cottage Grove

Sunshine Dairy v. Peterson, 183 Or 305, 324 (1948), describes the maxim as one interpretive guide rather than a mechanical rule. Cabell v. City of Cottage Grove, 170 Or 256, 281 (1942), likewise requires cautious use as an aid to determining legislative intent.

These decisions support the dissent’s call for examination of statutory purpose instead of assuming that enumeration alone extinguishes other judicial powers.

Vaughn v. Langmack

The dissent quotes Justice Rossman’s dissent in Vaughn v. Langmack, 236 Or 542, 574 (1964), cautioning against treating the maxim as an infallible navigational guide. Because the quoted passage comes from a separate opinion, it supplies persuasive criticism, not a controlling holding.

F. Comparative authority concerning inherent dismissal powers

People v. Thomas

People v. Thomas, 66 NYS 191 (NY Gen Term 1900), provides the dissent’s most developed comparative example. The New York statute required dismissal in two specified situations and included the restrictive phrase “but in no other.”

Nevertheless, the court distinguished mandatory dismissal from discretionary authority. It read the statute as requiring action only in the listed circumstances, without eliminating inherent power to set aside indictments for other adequate reasons. It also stated that removing inherent powers of a court of general jurisdiction requires clear and unequivocal legislative language.

The court illustrated its reasoning through a hypothetical indictment returned without the required grand jury participation or concurrence. Those numerical requirements belonged to the New York provisions discussed there; they are not presented as Oregon standards.

The analogy is historically relevant because Oregon’s early criminal procedure drew substantially from New York’s code. It remains persuasive comparative material, not an Oregon holding.

People v. Molineux

People v. Molineux, 57 NYS 936, 937–39 (NY Gen Sess 1899), supports the New York tradition invoked in People v. Thomas. It recognized discretionary judicial inspection of grand jury minutes and stated that an indictment unsupported by sufficient legal evidence could not stand.

Its relevance extends to both sides of Driver’s procedural problem: judicial access to the evidentiary record and authority to act on defects revealed by that record.

People v. Lawson

People v. Lawson, 67 Ill 2d 449 (1977), recognized authority to dismiss a charge for a clear denial of due process even though that ground was absent from the statutory list. The Illinois court connected that authority to the trial court’s responsibility to ensure a fair trial.

This demonstrates that a statutory enumeration need not invariably exhaust judicial dismissal powers. Its limits are equally important: the case involved an unequivocal due process violation, not a holding that every statutory grand jury evidentiary violation requires dismissal.

State v. Manley

State v. Manley, 197 Iowa 46 (1924), considered an indictment allegedly supported in part by hearsay. The court did not definitively recognize inherent authority beyond statutory dismissal grounds, and declined relief because the circumstances did not require exercise of any such power.

Justice James reads the decision as leaving the underlying authority question open. It therefore offers only qualified support: the possible existence of a power does not establish that a particular evidentiary defect warrants its use.

State v. Baughman and State v. Olson

State v. Baughman, 111 Iowa 71 (1900), reserved the inherent-power question until a case necessarily required its resolution. State v. Olson, 249 Iowa 536, 547 (1957), assumed the power for purposes of analysis but found no proper case for exercising it.

Together with State v. Manley, these authorities reinforce the distinction between recognizing judicial power and determining when relief is justified. They do not establish an automatic remedy for grand jury hearsay.

G. The difficulty of obtaining review after trial

State v. Guse

State v. Guse, 237 Or 479, 482 (1964), states that examining the sufficiency of grand jury evidence after trial serves no useful purpose: acquittal makes the matter moot, while conviction makes it irrelevant.

Justice James reasons that similar reasoning might obstruct later review of the remedial-authority question. That possibility strengthens his preference for considering mandamus before trial. He describes mandamus as a plausibly necessary avenue, not as an established exclusive remedy for this category of claim.

H. Legislative history and secondary authorities

The dissent also cites scholarship discussing grand jury hearsay and reform by Beverly A. Patterson, John G. Cook, Peter Arenella, and Leonard B. Boudin, along with congressional hearing materials. Those sources supply policy context rather than binding rules.

Max Radin’s discussion of statutory interpretation challenges the assumption that naming one category logically excludes all others. The cited Cyclopedia of Law and Procedure and Sutherland Statutory Construction materials explain the exclusion maxim and caution against overuse. A Harvard Law Review note similarly examines how reading mandatory language can implicitly add qualifications or consequences not expressly enacted.

Frederic E. Brown’s historical account of Oregon’s codes supports the relevance of the New York comparison. Legislative testimony and proposed amendments from 2017 support Justice James’s conclusion that Oregon consciously retained its grand jury hearsay restriction despite prosecutorial proposals to relax it.

5. Legal Reasoning and the Unresolved Questions

A. A legislative prohibition without a clear judicial remedy

The dissent’s central concern is an enforcement gap. Oregon prohibits specified grand jury hearsay, yet existing dismissal precedent may prevent courts from correcting an indictment obtained through that prohibited evidence.

Justice James emphasizes two legislative developments. First, the commentary accompanying OEC 101 rejected the view that the restriction was merely advisory. Second, in 2017 the legislature retained the restriction while requiring grand jury recording, notwithstanding proposals from the Oregon District Attorneys Association to permit broader officer-relayed hearsay.

Those developments support the seriousness of the prohibition. They do not, by themselves, establish which remedy follows from its violation. That distinction is precisely why the dissent sought fuller review.

B. Mandatory statutory grounds and discretionary judicial power

The proposed interpretation separates two propositions:

  • ORS 135.510 requires dismissal when its specified conditions are met.
  • A court might possess an independent power permitting dismissal in additional circumstances.

Those propositions can coexist unless the statute excludes the independent power. Justice James questions whether earlier cases established that exclusion after considering all relevant sources of authority.

This is not an argument that courts may disregard legislative limits. It is an argument about whether the legislature actually imposed the asserted limit and whether prior decisions examined that question adequately.

C. Transcript restrictions create a second barrier

Even a recognized remedy would leave a separate evidentiary-access problem. ORS 132.270(7)(b) prohibits using transcripts to challenge a true-bill endorsement or the proceedings leading to it. Driver’s request for judicial inspection therefore required analysis beyond whether good cause existed.

Driver’s constitutional challenge attempted to overcome that barrier. Neither the per curiam disposition nor the dissent resolved its merits. Nor did the Supreme Court decide whether requesting a preliminary hearing, rather than dismissal, avoided the statutory restriction.

D. The circuit court’s legal premise matters

Justice James observed that a good-cause determination would likely be reviewed for abuse of discretion, but that the circuit court appeared to rely on a legal premise: no meaningful relief was available.

A discretionary decision based on an incorrect understanding of judicial authority presents a different problem from an ordinary discretionary refusal. Whether the premise was incorrect remained unanswered, but its apparent role explains why the dissent considered clarification valuable.

E. Preliminary hearings are not an established substitute

Oregon’s constitutional preliminary-hearing requirement concerns prosecutions initiated by information. Driver sought to use that mechanism to obtain a judicial probable-cause determination notwithstanding the existing indictment.

The decision does not establish an entitlement to such a substitute hearing. The state’s objection—that the request effectively challenged the indictment—also remained unresolved by the Supreme Court.

F. The 2026 hearsay amendment complicates relief

After Driver’s indictment, Oregon Laws 2026, chapter 71, section 1, added ORS 40.460(27). The new exception potentially covers victim statements concerning specified commercial-sex-related offenses, including promoting prostitution.

The exception requires, among other things, that the statement:

  • Be made by a victim within 24 hours before or after engaging in, offering, or agreeing to engage in the commercial sex act;
  • Be electronically or writtenly recorded, or made to one of the specified officials or emergency responders; and
  • Have sufficient indications of reliability.

Reliability must be assessed from all surrounding circumstances. Listed considerations include personal knowledge, independent corroboration, timing, leading questions, and subsequent statements. Recantation alone is insufficient to deny admission without other indications of unreliability.

The amendment may make some statements admissible at trial that were more likely inadmissible when the indictment was obtained. It does not establish that Driver’s particular statements satisfy the exception.

Justice James expressly declined to decide whether later trial admissibility would render the earlier grand jury use harmless. Neither retroactive validation of the indictment nor an automatic entitlement to relief can be inferred from the decision.

6. Potential Impact

Immediate effect

Driver received no mandamus relief, and the circuit court’s order remained undisturbed. The Supreme Court did not adopt the dissent’s proposed interpretation or displace existing dismissal precedent.

Future litigation

The dissent identifies questions that a future case could squarely present: the existence and limits of Oregon supervisory authority, the intended exclusivity of ORS 135.510, lawful access to grand jury transcripts, and the significance of later evidentiary changes.

Those questions remain open in this decision. In particular, it supplies no rule governing prejudice, harmlessness, the amount of improper evidence necessary for relief, or the choice among possible remedies.

Grand jury practice

Denial of mandamus does not make prohibited hearsay permissible. Prosecutors must still distinguish admissible statements from inadmissible hearsay and establish the requirements of any applicable exception. Conversely, the presence of officer-relayed statements alone does not prove a violation.

Institutional significance

The case highlights the interaction between legislative safeguards, judicial supervision, and procedural access to review. Recording grand jury proceedings can improve transparency, but its remedial value depends on when courts may examine those recordings and what action they may take.

A future merits decision recognizing inherent authority would still need to define its boundaries. A decision rejecting such authority would sharpen the question whether legislative clarification is needed to provide an effective remedy.

7. Complex Concepts Simplified

Hearsay and inadmissible hearsay
Hearsay generally means an out-of-court statement offered to prove what it asserts. Some hearsay is admissible under an exception. Driver’s claim concerned prohibited, inadmissible hearsay—not every statement repeated by an officer.
Grand jury and “true bill”
A grand jury decides whether criminal charges should proceed, not whether the accused is guilty. A “true bill” is its formal approval of an indictment.
Indictment and information
An indictment comes from a grand jury. An information is a prosecutor’s charging document. Oregon’s constitutional preliminary-hearing provision discussed here applies to prosecution by information.
Mandamus
An extraordinary court order directing performance of a legal duty. It is not an ordinary appeal, and the court retains discretion over whether to entertain the proceeding.
Alternative writ and final relief
An alternative writ moves the proceeding forward by requiring action or a response justifying noncompliance. Issuing one would not itself establish that Driver deserved dismissal or other ultimate relief.
In camera review
Examination by the judge privately, rather than through public disclosure. Private review does not necessarily avoid statutory limits on the purpose for which records may be used.
Inherent supervisory authority
Judicial power associated with courts’ institutional responsibilities, rather than derived solely from an express statutory grant. Its existence and scope for this particular remedy remain unresolved.
Dictum
A statement not necessary to deciding a case. Justice James suggested that earlier exclusivity language might qualify; the court did not adopt that characterization.
Expressio unius est exclusio alterius
An interpretive tool suggesting that expressly listing some things may exclude others. It is not an automatic rule and must be tested against statutory context and purpose.
Harmlessness
The possibility that an error does not justify relief because of its legal or practical consequences. The opinion does not decide whether the later hearsay exception made any earlier violation harmless.

8. Conclusion

State v. Driver denies mandamus without resolving the substantive controversy. Its principal contribution is the dissent’s examination of whether Oregon’s mandatory grand jury hearsay restriction has an effective judicial remedy.

Existing precedent remains undisturbed, and the dissent is not binding law. The broader question persists: whether statutory dismissal grounds exhaust judicial authority, or leave room for carefully limited supervision to enforce legislative protections at the charging stage.
