Washington Material Witness Warrants: What State v. Denman Shows

A Washington material witness warrant can authorize the arrest of an important witness who fails to appear in a criminal case, but Washington law places conditions on when a court may issue one. A recent unpublished Court of Appeals decision, State v. Denman, No. 60171-1-II, illustrates how those requirements can apply when a reluctant witness does not appear for trial.

In Denman, the Washington Court of Appeals, Division Two, concluded that the trial court did not abuse its discretion by issuing a material witness warrant after the State personally served its only trial witness with a subpoena on the morning of trial and the witness nevertheless failed to appear.

The decision also provides an opportunity to explain an important distinction in Washington appellate law: Denman is an unpublished opinion and does not have the same precedential value as a published Washington appellate decision.

What Happened in State v. Denman?

The State charged Denman with first-degree vehicle prowl and felony violation of a court order—domestic violence. The alleged victim, identified by the Court of Appeals as LH, was listed as a State witness.

On the morning of trial, LH emailed the State and said that she could not come to court.

The prosecution attempted to locate her. Although there was uncertainty about whether an earlier subpoena had been properly served, an officer found LH that morning and personally served her with a subpoena requiring her to appear at 10:30 a.m.

According to the State, LH told the officer that she would come to court.

She did not.

The State then requested a material witness warrant. Denman objected, arguing in part that the State had mishandled the situation by failing to ensure that its witness was properly subpoenaed before trial.

The trial court granted the State’s request.

Officers were unable to locate LH that afternoon, and the court ultimately allowed the State until the following morning to produce her. The State did so, and LH testified at trial.

The jury convicted Denman of felony violation of a court order—domestic violence—and the lesser offense of first-degree criminal trespass rather than first-degree vehicle prowl.

Denman appealed.

What Is a Washington Material Witness Warrant?

The requirements for a Washington material witness warrant in a criminal case are primarily found in CrR 4.10 — Material Witnesses.

Under CrR 4.10(a), either the prosecution or the defense may seek a warrant for a material witness.

The party seeking the warrant must show, by affidavit or on the record in open court, that the witness’s testimony is material and that one of three circumstances exists:

The witness has refused to submit to a court-ordered deposition under CrR 4.6;
The witness has refused to obey a lawfully issued subpoena; or
It may become impracticable to secure the witness’s presence through a subpoena.

A material witness warrant therefore is not simply a mechanism for arresting any witness who is reluctant to testify. The requirements of the court rule must be established.

Why the Subpoena Mattered in Denman

A central issue in Denman concerned service of the subpoena.

Earlier that morning, the State could not initially confirm that LH had been personally served. The prosecution indicated that a subpoena previously had been sent to LH by email at her request, but Denman challenged whether that constituted proper service.

That issue changed when an officer located LH at approximately 9:30 a.m. and personally served her with a subpoena requiring her appearance at 10:30 a.m.

LH reportedly said she would appear but failed to do so.

The Court of Appeals concluded that these circumstances satisfied CrR 4.10(a)(2). LH had been personally served with a lawful subpoena and then failed to obey it.

Importantly, the appellate court stated that Denman identified no rule requiring a subpoena to be served a specified number of days before the witness’s required appearance.

Did the State Have to Show Due Diligence?

Denman argued that the State’s handling of its witness demonstrated a lack of due diligence.

The Court of Appeals disagreed.

In addition to personally serving LH, the State had communicated with her before trial, emailed her a subpoena, attempted to call and email her on the morning of trial, and sent an officer to locate her.

Once personally served, LH still failed to appear.

The appellate court concluded that these circumstances supported the trial court’s decision to issue the warrant.

Denman also relied on Washington cases addressing a party’s diligence when requesting a trial continuance because of an absent witness. But the Court of Appeals distinguished those cases because the trial court had recessed proceedings rather than granting the type of continuance addressed by those authorities.

Are Material Witness Warrants Coercive?

Denman also argued that the warrant created an inherently coercive atmosphere surrounding LH’s testimony.

The Court of Appeals was not persuaded.

The court acknowledged prior authority describing a material witness warrant as a “drastic measure.” But it reasoned that subpoenas and material witness warrants necessarily contain a degree of coercion because they compel a person’s appearance in court.

The important question was whether the requirements authorizing the warrant were satisfied.

The court concluded that they were.

That does not mean a material witness warrant is automatically appropriate whenever a witness fails to appear. Courts must still apply CrR 4.10 to the particular circumstances presented.

The Court Rejected Denman’s Governmental Misconduct Argument

Denman also argued that the prosecution’s handling of LH amounted to governmental misconduct or mismanagement.

Washington’s CrR 8.3(b) permits dismissal of a criminal prosecution in circumstances involving arbitrary action or governmental misconduct and the required prejudice to the accused.

Washington courts have recognized that misconduct under this rule does not necessarily require intentional wrongdoing. In appropriate circumstances, governmental mismanagement can be sufficient.

But the Court of Appeals found no such misconduct in Denman.

First, the State personally served LH before seeking the material witness warrant.

Second, Denman argued that prosecutors had misrepresented LH’s reasons for failing to appear. The appellate court rejected that argument because the State had presented LH’s own communications to the trial court, including messages expressing concerns about Denman’s release from custody.

The court concluded that neither alleged mismanagement nor misrepresentation had been established.

Why State v. Denman Being an Unpublished Opinion Matters

There is an important limitation to any discussion of State v. Denman: the Court of Appeals designated the opinion as unpublished.

At the end of the decision, the panel expressly stated that the opinion would not be printed in the Washington Appellate Reports but would be filed for public record pursuant to RCW 2.06.040.

Unpublished Opinions Do Not Have Precedential Value in Washington

An unpublished Washington Court of Appeals opinion does not have precedential value.

Washington’s GR 14.1 — Citation to Unpublished Opinions governs when unpublished appellate decisions may be cited.

Under GR 14.1(a), unpublished opinions of the Washington Court of Appeals filed on or after March 1, 2013, may be cited as nonbinding authorities if the party believes the opinion has persuasive value on a material issue and no published Washington opinion would serve as well.

That distinction is critical.

Denman can help lawyers and the public understand how one panel of the Court of Appeals analyzed a material witness warrant under the particular circumstances of that case. But it should not be described as establishing a new binding rule of Washington law.

A Washington trial court is not required to follow Denman in the way it generally must follow applicable published appellate precedent.

Persuasive Authority Is Different From Binding Precedent

The difference between precedential and persuasive authority is particularly important when reading legal articles about recent appellate decisions.

A published appellate decision can establish precedent governing later cases within the Washington court system. An unpublished decision such as Denman does not perform that same function.

Instead, where GR 14.1 permits its citation, a lawyer may point to the unpublished decision because its reasoning is potentially persuasive.

That is why the primary legal authority for the material-witness issue remains CrR 4.10 and applicable published Washington cases interpreting that rule, rather than Denman itself.

What Denman Can Still Teach Us About Washington Material Witness Warrants

Although Denman is not precedential, the opinion highlights several practical issues that can arise when a witness fails to appear for a Washington criminal trial.

Proper Service Can Be Critical

A party requesting a material witness warrant should be prepared to establish the basis for the warrant under CrR 4.10.

In Denman, personal service on the morning of trial became particularly important because there had been uncertainty over the earlier subpoena.

A Same-Day Subpoena Is Not Automatically Invalid

The Court of Appeals noted that Denman did not identify authority requiring a subpoena to be served a particular number of days before the witness must appear.

That observation should be understood in context. Because Denman is unpublished, it should not be treated as creating a generally binding rule regarding every same-day subpoena.

The Court Considers the Efforts Made to Secure the Witness

The State had attempted multiple methods of communicating with LH and ultimately arranged for personal service.

Those facts supported the court’s conclusion that issuance of the warrant was within the trial court’s discretion.

A Material Witness Warrant Is a Significant Exercise of Judicial Authority

A warrant can result in a witness being taken into custody even though that person is not the defendant in the criminal case.

For that reason, Washington courts have described material witness warrants as a drastic measure. Whether one is justified depends on the requirements of CrR 4.10 and the circumstances before the court.

Washington Material Witness Warrants and Criminal Defense

Witness availability can significantly affect a criminal prosecution. When a key witness does not appear, questions can arise concerning subpoenas, continuances, material witness warrants, confrontation rights, admissibility of statements, and alleged governmental misconduct.

State v. Denman illustrates how quickly those issues can develop during trial. It also demonstrates why defendants should preserve objections and create a clear record when challenging the State’s efforts to secure a witness.

At the same time, because Denman is unpublished, defendants and attorneys should be careful not to treat the opinion as binding Washington precedent. The analysis must begin with the applicable court rules, statutes, constitutional protections, and published appellate decisions.
