Counsel Must Seek a Mistrial When Jurors See a Shackled Defendant Outside the Courtroom and No Protective Measures Are Taken

Case: Nelson v. Cain, 375 Or 614 (2026)

Court: Supreme Court of Oregon

Date: October 1, 2026

Author: DeHoog, J.; Bushong, J., dissenting

Introduction

Nelson v. Cain addresses whether criminal defense counsel provides constitutionally inadequate assistance by failing to seek a mistrial after jurors see the defendant outside the courtroom wearing jail clothes and visible restraints. Petitioner Quandray J. Nelson was being transported from the courthouse when at least three jurors saw him in a belly chain, handcuffs, ankle restraints, and jail clothing. Although Nelson informed trial counsel, counsel made no motion and created no record of the incident.

The case arose in post-conviction proceedings under ORS 138.530(1)(a). Nelson argued that counsel’s failure deprived him of adequate assistance under Article I, section 11, of the Oregon Constitution and effective assistance under the Sixth Amendment. The post-conviction court denied relief, and the Court of Appeals affirmed.

The Oregon Supreme Court reversed. It held that existing shackling law, although directed primarily at in-court restraints, made a mistrial argument sufficiently apparent and beneficial that competent counsel was required to raise it. Under the circumstances, seeking a mistrial on the record was the only reasonable course.

Central rule: When jurors see a criminal defendant visibly shackled outside the courtroom during an ongoing trial, and no inquiry or corrective measure is taken, competent defense counsel must recognize the constitutional danger and seek a mistrial on the record when doing so presents an obvious potential benefit and no identified countervailing risk.

Factual and Procedural Background

Nelson was charged with offenses arising from a domestic-violence incident involving assault, nonconsensual sexual conduct, and unauthorized use of a vehicle. After his first trial, the Court of Appeals reversed several sexual-offense convictions because of an erroneous jury instruction in State v. Nelson, 241 Or App 681 (2011).

Nelson was retried in 2013. After deliberating on Friday without reaching a verdict, the jurors were dismissed for the weekend. As four or five jurors descended the courthouse stairs, deputies began escorting Nelson from a holding cell. He was wearing jail clothes and visible handcuffs, ankle restraints, and a belly chain. At least three jurors looked at him before deputies pulled him back into the cell.

Nelson told counsel when proceedings resumed Monday. Counsel recalled speaking with deputies and bringing the matter to the judge and prosecutor, apparently in chambers. Nothing was placed on the record. Counsel did not request a mistrial, ask the court to question the jurors, seek a curative instruction, or request any other protective measure. The jury later convicted Nelson of rape and sexual-abuse offenses.

In post-conviction proceedings, Nelson alleged that counsel’s inaction constituted inadequate assistance. The post-conviction court found that counsel had discussed the matter informally but denied relief because no Oregon appellate case had expressly held that a brief hallway observation of a restrained defendant required a mistrial. It also found insufficient proof of prejudice. The Court of Appeals affirmed in Nelson v. Cain, 334 Or App 326 (2024).

Summary of the Opinion

The Supreme Court held that Nelson satisfied both elements of an inadequate-assistance claim:

  1. Deficient performance: Counsel failed to exercise reasonable professional skill and judgment. Existing Oregon law clearly recognized the danger that visible restraints can undermine the presumption of innocence and jury impartiality. Although no controlling case had addressed an identical hallway encounter, competent counsel would have recognized a substantial and obviously beneficial mistrial argument.
  2. Prejudice: Counsel’s failure had a tendency to affect the result. There was more than a mere possibility that the trial court would have granted a mistrial or taken protective measures such as questioning jurors, replacing affected jurors, or giving a curative instruction.

The Court did not adopt Nelson’s proposed rule that prejudice must always be presumed whenever jurors see a defendant in restraints. Nor did it hold that every out-of-court sighting automatically requires a mistrial. Its holding rested on counsel’s duty to recognize and litigate the issue under the particular record.

The Court affirmed the Court of Appeals as to Nelson’s other claims, reversed as to the shackling claim, reversed the circuit court’s judgment, and remanded for further proceedings.

Analysis

1. Governing Standards for Inadequate Assistance

Under Article I, section 11, a post-conviction petitioner must prove by a preponderance of the evidence that counsel failed to exercise reasonable professional skill and judgment and that the failure caused prejudice.

Krummacher v. Gierloff established that counsel must investigate the facts and applicable law sufficiently to advise and represent the defendant in an informed manner. It also cautioned that the Constitution guarantees adequate—not perfect—representation.

Lichau v. Baldwin supplied the two-part performance-and-prejudice framework and emphasized that counsel’s conduct must be assessed from counsel’s perspective at the time, without hindsight. Together with Ball v. Gladden, it also governs review of post-conviction factual findings: supported historical findings are binding, and omitted findings may be inferred consistently with the judgment when the record permits competing findings.

Stevens v. State required tactical choices to reflect a reasoned evaluation of the case’s complexity, costs, and potential benefits. Richardson v. Belleque emphasized the importance of what counsel knew and what was at stake. Farmer v. Premo clarified that gathering information is not enough; counsel must reasonably understand its significance.

Pereida-Alba v. Coursey addressed claims that counsel overlooked an available strategy. The inquiry includes whether the strategy actually pursued was reasonable and whether counsel should have recognized the omitted option.

2. Counsel’s Duties When the Law Is Unsettled

The post-conviction court reasoned that counsel was not deficient because no Oregon appellate decision expressly governed a juror’s brief hallway observation of a shackled defendant. The Supreme Court rejected that reasoning as too narrow.

Burdge v. Palmateer establishes that counsel’s responsibility is not confined to settled legal propositions. Counsel may be inadequate for failing to advance an unresolved argument when:

  • the legal issue is reasonably identifiable;
  • a favorable interpretation would provide an obvious benefit;
  • competent counsel would recognize that interpretation; and
  • the potential benefit exceeds any identifiable risk.

Applying Burdge v. Palmateer, the majority held that competent counsel would have recognized that Oregon’s established shackling principles could apply outside the courtroom. The absence of a factually identical precedent did not excuse complete inaction.

The Court also relied on the principle discussed in Delgado-Juarez v. Cain: a post-conviction court may not invent strategic reasons for counsel’s conduct when the record does not show that counsel actually considered those reasons. Here, the record did not establish that counsel weighed the advantages and disadvantages of a mistrial motion. Counsel’s unexplained inaction therefore could not be protected through post hoc tactical speculation.

3. The Shackling Precedents

State v. Smith and the common-law rule

In State v. Smith, 11 Or 205 (1883), the Court reversed a murder conviction because the defendant had been kept in leg irons during trial without adequate justification. It adopted the common-law principle recognized in People v. Harrington that defendants ordinarily must be tried free from physical restraints.

State v. Long and Eaddy v. People

State v. Long explained that a defendant may be shackled only when restraint is necessary for safety and order. Quoting Eaddy v. People, the Court identified the central danger: jurors may develop prejudice against a prisoner who appears before them in handcuffs or shackles, interfering with a fair determination of guilt.

State v. Kessler and People v. Duran

State v. Kessler held that shackling cannot rest on an unsupported assertion of risk. The prosecution must establish an immediate and serious security need. Drawing from People v. Duran, the decision identified four harms caused by visible restraints:

  1. They undermine the presumption of innocence.
  2. They diminish the dignity of judicial proceedings.
  3. They may interfere with consultation between defendant and counsel.
  4. They may affect the defendant’s decision whether to testify.

Particularly important to Nelson, State v. Kessler characterized the prejudice from unjustified visible shackling as “manifest.” It reasoned that the problem is not how long jurors see the shackles but whether they see them at all.

Guinn v. Cupp

In Guinn v. Cupp, the Supreme Court relied on State v. Kessler in holding that a post-conviction petitioner may establish a prima facie claim by showing that the defendant was shackled during trial without a supporting record of necessity. Nelson treated Guinn v. Cupp as an effective endorsement of Kessler’s reasoning and as notice that counsel’s failure to protect against unjustified shackling can constitute inadequate assistance.

Related Oregon cases

  • State v. Wall reaffirmed that visible restraints require substantial justification on the record.
  • State v. Moore, 45 Or App 837 (1980), required evidence of a serious security risk before restraints may be used.
  • State ex rel Juv. Dept. v. Millican applied comparable protections to juvenile proceedings.
  • State v. Merrell recognized that Oregon courts treat shackling similarly under Article I, section 11, and federal due process.
  • State v. Bates and State v. Bowen distinguished restraints that were not visible or known to the jury.
  • Sproule v. Coursey stated that prejudice is presumed when restraints cannot effectively be concealed from jurors, but not when jurors are unaware of them.
  • State v. Washington, decided after Nelson’s trial, expressly located the right to appear free from unnecessary restraints in Article I, section 11’s impartial-jury guarantee.
  • State v. Guzek upheld a stun belt when the record supported the need for that restraint.

Federal constitutional authorities

Estelle v. Williams held that trying a defendant in prison clothing may undermine the presumption of innocence. Illinois v. Allen recognized that courtroom restraints implicate due process but may be justified when necessary to control a disruptive defendant. Strickland v. Washington supplies the federal ineffective-assistance framework, which Oregon treats as functionally equivalent, though independently analyzed, under Montez v. Czerniak.

4. Why the Hallway Location Did Not Eliminate the Problem

The state argued that in-court shackling is inherently different from a brief, accidental hallway sighting. The majority rejected a categorical distinction. The most important harm—the possibility that jurors will perceive the defendant as dangerous or guilty—can arise wherever the jurors see the restraints.

That concern was especially significant because Nelson was being tried for offenses involving forcible compulsion. Seeing him in extensive restraints could reinforce an inference that he was dangerous, directly intersecting with a disputed feature of the prosecution.

The majority acknowledged that several non-Oregon decisions distinguish incidental out-of-court sightings from in-court shackling. These included State v. Cassel, State v. Elliott, Wharton v. Chappell, United States v. Halliburton, and United States v. Leach. Those cases reasoned that jurors understand defendants may be restrained during transportation.

The majority found that reasoning cursory and unpersuasive as a basis for excusing counsel’s inaction. Even if the trial court ultimately might have followed those cases, they did not foreclose a substantial argument under Oregon law.

5. State v. Walton and Available Protective Measures

State v. Walton involved a juror and an alternate juror seeing the defendant in handcuffs with other prisoners. Defense counsel moved for a mistrial. The trial court questioned the jurors, confirmed their impartiality, instructed them to disregard the incident, and offered to replace the sitting juror. The Supreme Court found no reversible error in denying a mistrial.

The majority viewed State v. Walton as supporting Nelson rather than foreclosing relief. It demonstrated that a mistrial motion can prompt meaningful protective action even if the court does not declare a mistrial. Nelson’s counsel obtained none of those protections because he made no motion and created no record.

6. Prejudice

Under Green v. Franke, constitutionally deficient performance is prejudicial if it had a tendency to affect the result. In the majority’s formulation, that requires more than a mere possibility but less than proof that a different result was probable.

The majority applied that standard to the omitted mistrial motion. Under State v. Rogers, State v. Farrar, and State v. Smith, 310 Or 1 (1990), a mistrial decision rests in the trial court’s discretion because the trial judge is best positioned to assess and remedy prejudice.

There was more than a mere possibility that the trial court would have:

  • granted a mistrial;
  • questioned the affected jurors;
  • replaced one or more jurors with alternates;
  • given an instruction protecting the presumption of innocence; or
  • otherwise acted to ensure impartiality.

State v. Evans, United States v. Moreno, and United States v. Pina illustrated those alternatives. Because counsel’s omission deprived Nelson of any opportunity to obtain them, the omission had a tendency to affect the proceeding.

The Court also cited Rhoden v. Rowland, where the sight of restraints was especially concerning because dangerousness and force were central trial issues. Similarly, Lichau v. Baldwin supported finding prejudice where omitted material could have affected a jury’s resolution of a central credibility issue.

7. No Automatic Presumption or Automatic Mistrial

The Court deliberately stopped short of holding that every juror observation of a restrained defendant is presumptively prejudicial. It also did not hold that every such observation compels a mistrial. The new precedent concerns counsel’s professional obligation to recognize the issue, make a record, and seek relief when the circumstances present an obvious constitutional danger.

The Dissent

Justice Bushong disagreed on both performance and prejudice.

Performance

The dissent emphasized that Nelson bore the burden of proof and that the record was sparse. Counsel had investigated the incident and told Nelson there was “no reason” for a mistrial. The dissent believed the post-conviction court could infer that counsel learned the jurors had not recognized Nelson.

Relying on Gorham v. Thompson and Montez v. Czerniak, the dissent warned against second-guessing tactical choices. It also observed that a mistrial may carry disadvantages. State v. Moore, 361 Or 205 (2017), demonstrated that defendants sometimes prefer to keep a favorable jury. A retrial also would require the victim to testify again, a concern illustrated by People v. Cogswell.

The dissent read Burdge v. Palmateer narrowly. It invoked Antoine v. Taylor, Jackson v. Franke, State v. Hale, State v. Southard, Miller v. Lampert, and Apprendi v. New Jersey to argue that counsel generally need not anticipate a later expansion of unsettled law unless existing authority clearly foreshadows it.

It also relied on U.S. v. Jones, Williams v. Woodford, Schiro v. Clark, Clark v. Wood, United States v. Diecidue, United States v. Taylor, Sweet v. State, Jenkins v. State, and State v. Hardy. Those decisions generally require proof of actual prejudice when jurors briefly see a defendant restrained outside the courtroom.

Prejudice

The dissent argued that Green v. Franke’s “more than a mere possibility” formulation should be limited to assessing effects on a jury verdict. It would have required Nelson first to show that the trial court probably would have granted the omitted motion or other relief.

Drawing on Peiffer v. Hoyt, Monahan v. Belleque, State v. Woodall, and State v. Embry, the dissent reasoned that mistrial is a drastic remedy and that questioning, replacement of jurors, or a curative instruction would have been more likely. At most, counsel’s omission had a conceivable effect, which the dissent regarded as insufficient.

Complex Concepts Simplified

Inadequate or ineffective assistance of counsel
A constitutional failure by a lawyer to perform with reasonable professional skill and judgment, coupled with resulting prejudice.
Mistrial
An order ending the current trial without a verdict because an event has made a fair continuation impossible or seriously doubtful. The case may ordinarily be retried.
Presumption of innocence
The rule that jurors must treat the defendant as innocent unless the prosecution proves guilt beyond a reasonable doubt. Visible restraints may undermine that presumption by suggesting dangerousness or guilt.
Manifest or presumed prejudice
Harm regarded as so inherent in a practice that the defendant need not prove what each juror actually thought. The Court declined to create a universal presumption for every out-of-court sighting.
Actual prejudice
Evidence that jurors were in fact influenced or biased. The majority did not require Nelson to prove the jurors’ subjective thoughts.
Tendency to affect the outcome
Oregon’s post-conviction prejudice standard. In this case, it required more than a speculative possibility but less than proof that a different result was probable.
Post hoc rationalization
A strategic explanation invented after the event. Courts generally may not uphold counsel’s conduct on a supposed strategy that the record does not show counsel actually considered.
Curative instruction
A direction telling jurors to disregard an improper event or inference. It is a possible alternative to declaring a mistrial.

Impact

  • Defense counsel must act promptly. Counsel should investigate, place the incident on the record, and request appropriate relief rather than rely on informal discussions.
  • Unsettled law can still create a professional duty. A lawyer cannot ignore an obviously beneficial argument merely because no case has addressed identical facts.
  • Out-of-court shackling is constitutionally significant. A courthouse hallway does not automatically insulate a juror’s observation from the presumption-of-innocence concerns associated with courtroom restraints.
  • Mistrial motions serve broader functions. Even when a mistrial is denied, the motion may lead to juror questioning, replacement, instructions, or other safeguards.
  • Post-conviction courts must avoid speculative strategy. They may not excuse counsel’s omission by imagining tactical reasons unsupported by the record.
  • The holding remains fact-sensitive. It does not create an automatic mistrial rule or a universal presumption of prejudice whenever a juror glimpses a restrained defendant.

Conclusion

Nelson v. Cain extends the practical force of Oregon’s anti-shackling jurisprudence beyond the courtroom. The decision establishes that competent counsel must recognize the risk to jury impartiality when jurors see a defendant visibly restrained during trial and must seek meaningful, on-record relief when no reasonable countervailing consideration appears.

Its broader significance lies in its application of Burdge v. Palmateer: constitutional competence may require counsel to advance an unresolved but plainly beneficial legal argument. By failing to seek a mistrial or any protective measure, Nelson’s counsel denied him a meaningful opportunity to preserve the presumption of innocence and secure an impartial jury.
