Confrontation Clause Waiver in Minnesota: No Plain Error When Counsel Agrees to Admit Prior Testimony Without Defendant’s Personal Waiver

1. Introduction

In State of Minnesota v. Steven Douglas Nelson (Minn. May 20, 2026), the Minnesota Supreme Court considered whether a district court commits reversible error by admitting an adverse witness’s prior sworn trial testimony (read to the jury) when defense counsel agrees to its admission but the defendant does not personally, on the record, waive the Sixth Amendment right to confrontation.

The case arose from Nelson’s second trial (the first ended in a mistrial) for a brutal roadside assault on T.T. The State sought to use the first-trial testimony of D.A., a corroborating eyewitness, because D.A. did not appear to testify in person at the second trial. Defense counsel expressly agreed—twice— to the State’s proposal to read D.A.’s prior direct and cross-examination testimony to the jury. The district court admitted the transcript without addressing Nelson personally. After conviction, Nelson argued on appeal that admitting this testimony without his personal waiver violated the Confrontation Clause.

The central issue at the Minnesota Supreme Court was not the ultimate constitutional rule (whether a personal waiver is always required), but whether the district court’s approach amounted to plain error given the lack of a trial objection.

2. Summary of the Opinion

The court affirmed. Applying plain-error review, it held that—even assuming error—any error was not plain because no binding authority clearly required the district court to obtain Nelson’s personal, on-the-record waiver of confrontation before admitting the transcript where counsel agreed to its admission.

The court emphasized that neither it nor the United States Supreme Court has clearly held that confrontation is among the “fundamental decisions” that only the defendant personally may waive. The opinion therefore leaves open the underlying merits question (whether a personal waiver should be required in a preserved claim), while definitively resolving the question in the posture presented: the absence of controlling law prevents reversal under plain-error doctrine.

3. Analysis

A. Precedents Cited

State v. Tate, 985 N.W.2d 291 (Minn. 2023)
Cited for de novo review of Confrontation Clause challenges to admission of prior testimony. The court nevertheless applied plain-error review because Nelson did not object at trial.
State v. Tscheu, 758 N.W.2d 849 (Minn. 2008)
Reinforced that unobjected-to constitutional/evidentiary issues are generally forfeited and reviewed, if at all, under the plain-error framework.
State v. Griller, 583 N.W.2d 736 (Minn. 1998) and Johnson v. United States, 520 U.S. 461 (1997)
Provided the three-prong plain-error test (error, plainness, substantial rights). Johnson also supplies the key “plainness” definition: error must be clear or obvious under current law.
Pulczinski v. State, 972 N.W.2d 347 (Minn. 2022)
Cited for the discretionary fourth step of plain-error correction: even if the three prongs are met, relief is granted only if necessary to protect the fairness, integrity, or public reputation of judicial proceedings.
State v. Manley, 664 N.W.2d 275 (Minn. 2003)
Cited to confirm courts may address plain-error prongs in any order—here, the court resolved the case at the “plainness” prong.
State v. Webster, 894 N.W.2d 782 (Minn. 2017)
Supplied Minnesota’s formulation that an error is “plain” when it contravenes case law, a rule, or a standard of conduct.
Coy v. Iowa, 487 U.S. 1012 (1988); Maryland v. Craig, 497 U.S. 836 (1990); Mattox v. United States, 156 U.S. 237 (1895)
Used to describe the historical core of confrontation: face-to-face encounter and demeanor assessment, with Craig quoting Mattox on why live testimony matters for credibility.
Crawford v. Washington, 541 U.S. 36 (2004) and Davis v. Washington, 547 U.S. 813 (2006)
Crawford anchors modern confrontation doctrine for “testimonial hearsay”: testimonial statements are inadmissible unless the witness is unavailable and the defendant had a prior opportunity to cross-examine. Davis is cited for the “primary purpose” test defining testimonial statements. Notably, the court observed the State conceded it did not establish D.A.’s unavailability, but the appeal turned on the waiver/forfeiture posture under plain-error review rather than a fully preserved Crawford challenge.
New York v. Hill, 528 U.S. 110 (2000) and United States v. Olano, 507 U.S. 725 (1993)
These cases structure the waiver inquiry: whether counsel may waive a right “depend[s] on the right at stake” (Olano), and personal participation is required only for “certain fundamental rights” (Hill).
Jones v. Barnes, 463 U.S. 745 (1983); Brookhart v. Janis, 384 U.S. 1 (1966); Johnson v. Zerbst, 304 U.S. 458 (1938); McCoy v. Louisiana, 584 U.S. 414 (2018)
Cited as examples of decisions reserved to the defendant personally (pleading guilty, jury waiver, counsel waiver, testifying, appealing, maintaining innocence). The court relied on the consistent omission of confrontation from these enumerations to reject Nelson’s claim that personal waiver was clearly required.
Melendez-Diaz v. Massachusetts, 557 U.S. 305 (2009)
Cited for dicta that confrontation may be waived, including by failure to object, and that states may adopt procedural rules governing objections—supporting the court’s view that confrontation is routinely managed through ordinary trial procedure rather than always through personal colloquies.
State v. Blom, 682 N.W.2d 578 (Minn. 2004) and State v. Trifiletti, 6 N.W.3d 79 (Minn. 2024)
Blom supplies Minnesota’s general definition of waiver as intentional relinquishment of a known right. Trifiletti is cited for the proposition that confrontation rights may be waived, including by failure to object.
State v. Caulfield, 722 N.W.2d 304 (Minn. 2006)
Highly influential in the “plainness” analysis: the court of appeals—and the supreme court—highlighted Caulfield’s statement that “confrontation rights are not among those (right to a jury trial and right to counsel) that require an affirmative waiver in writing or on the record,” undercutting any claim that personal waiver was clearly mandated.
State v. Cassidy, 567 N.W.2d 707 (Minn. 1997); State v. Dukes, 544 N.W.2d 13 (Minn. 1996), abrogated on other grounds by State v. Dahlin, 695 N.W.2d 588 (Minn. 2005)
Cited to acknowledge confrontation is “fundamental,” while explaining that being “fundamental” does not automatically place a right into the narrow category requiring personal waiver as a matter of clearly established law.
State v. Little, 851 N.W.2d 878 (Minn. 2014) and State v. Gant, 996 N.W.2d 1 (Minn. App. 2023)
These illustrate Minnesota’s personal-waiver requirements for some rights (e.g., jury trial, counsel), used as a contrast to the unsettled status of personal waiver for confrontation.
Pointer v. Texas, 380 U.S. 400 (1965)
Cited to show the U.S. Supreme Court has long described confrontation as fundamental—yet still does not list it among the rights requiring personal waiver.
Diaz v. United States, 223 U.S. 442 (1912)
Discussed in a footnote as historical support that counsel may waive confrontation in some circumstances, but the court flagged serious limits on its authoritative weight: it was not decided under the U.S. Constitution and predates Crawford.

B. Legal Reasoning

The opinion is structured around the procedural posture. Because Nelson did not object when the transcript was offered—and his lawyer affirmatively agreed to its admission—the claim was forfeited absent the plain-error exception. The court therefore focused on whether it was clear or obvious under current law that confrontation can be waived only by the defendant personally.

The court’s reasoning proceeds in three moves:

Confrontation is fundamental, but not all fundamental rights require personal waiver.
The court accepted confrontation’s fundamental status (citing Cassidy, Dukes, and Pointer), but emphasized Hill and Olano: only “certain” fundamental rights require a personal, informed waiver, and which rights those are depends on the right’s nature.
Binding authorities do not clearly classify confrontation as a “personal-waiver-only” right.
The U.S. Supreme Court’s repeated listings of defendant-controlled decisions (Jones, Hill, McCoy) omit confrontation. Minnesota precedent contains language suggesting confrontation does not require an affirmative on-the-record waiver (Caulfield) and may be waived by failing to object (Trifiletti), making it especially difficult to label the district court’s conduct as clearly unlawful.
Therefore, even if error occurred, it was not “plain.”
Because “plainness” requires clear contravention of law (Johnson; Webster), and because no binding authority demanded a personal colloquy in this scenario, the court ended the analysis at the second prong and affirmed.

Importantly, the court did not definitively decide whether admitting D.A.’s testimony without a personal waiver is constitutionally erroneous in a preserved case. It decided only that the requirement was not sufficiently established to justify plain-error reversal.

C. Impact

1) Clarifies Minnesota plain-error boundaries for confrontation-waiver claims.
After Nelson, defendants who do not object at trial—and whose counsel agrees to admitting prior testimony—will face a steep obstacle on appeal. Unless and until controlling authority holds that personal waiver is required, the absence of a personal colloquy will rarely (if ever) be “plain error.”

2) Reinforces counsel’s practical control over many confrontation-related trial decisions (at least for forfeiture purposes).
The decision aligns confrontation procedure with ordinary trial management: objections, stipulations, and tactical evidentiary choices. That does not mean a personal waiver is never required, but it does mean that, in Minnesota, the law is not yet settled enough to treat its absence as obvious reversible error.

3) Leaves an open doctrinal question for future litigation.
The court expressly stopped short of deciding the merits. A future case—with a timely objection and a developed record—could squarely present whether the Sixth Amendment (or Minn. Const. art. 1, § 6) requires a personal, on-the-record waiver before admitting prior testimonial evidence when the witness is not shown unavailable.

4) Practice note for trial courts and litigants.
While not required here, trial courts may still choose to conduct a brief colloquy as a prudential measure, particularly where the State is relying on prior testimony and unavailability is disputed or weakly supported. Defendants who want to preserve the issue must object; reliance on after-the-fact personal-waiver arguments is unlikely to succeed under plain-error review.

4. Complex Concepts Simplified

Confrontation Clause (Sixth Amendment): The constitutional right of a criminal defendant to face and cross-examine witnesses who testify against them, allowing the jury to assess credibility.
Testimonial hearsay: An out-of-court statement made under circumstances suggesting it will be used in prosecution (e.g., prior testimony, formal police interrogation). Under Crawford v. Washington, it is generally inadmissible unless the witness is unavailable and the defendant had a prior opportunity to cross-examine.
Unavailability: A witness is “unavailable” when they cannot be brought to testify despite appropriate legal efforts. If the witness is not truly unavailable, using prior testimony can violate confrontation. In Nelson, the State conceded it did not establish unavailability, but the appeal turned on forfeiture/plain-error rather than a preserved Crawford claim.
Waiver vs. forfeiture: Waiver is the intentional relinquishment of a known right (often strategic). Forfeiture is the loss of a claim by failing to assert it in time (e.g., not objecting). For forfeited claims, appellate review is limited to “plain error.”
Plain-error review: A narrow appellate safety valve for unpreserved errors. The defendant must show (1) error, (2) that is clear/obvious under current law, and (3) that affects substantial rights; even then, relief is discretionary.

5. Conclusion

State v. Nelson establishes a practical rule of appellate review in Minnesota: when defense counsel agrees to admit an adverse witness’s prior sworn testimony, the district court’s failure to obtain the defendant’s personal, on-the-record confrontation waiver is not “plain error” because current binding law does not clearly impose such a requirement.

The decision is significant less for resolving the ultimate constitutional question and more for defining the consequences of failing to object. It underscores that confrontation disputes must be litigated in real time at trial to preserve full appellate review—and it leaves the door open for a future, preserved case to decide whether personal waiver is constitutionally required.
