STATE OF WASHINGTON, ) ) No. 39315-1-III Respondent, ) ) v. ) ) JOHN HENRY SLIGER, ) UNPUBLISHED OPINION ) Petitioner. )
STAAB, A.C.J. — John Sliger is charged with vehicular homicide. At the scene of
the accident Sliger removed a lump of chewing tobacco from his mouth. Prior to taking a
breath test, when asked if he had any foreign substances in his mouth, he answered no.
After checking his mouth, the officer noted strands of tobacco in his teeth that were not
removed prior to taking the test. Sliger filed a pretrial motion to suppress the breath test
results.
For a breath test to be admissible under RCW 46.61.506(4)(a)(iii), the State must
produce prima facie evidence that the subject did not have any foreign substances in their
mouth at the beginning of the observation period. This burden can be met with evidence
that either the subject denied having anything in their mouth or evidence that a check of
the mouth revealed no foreign substances. Here, the trial court found that tobacco was a
foreign substance, that Sliger removed the tobacco from his mouth before taking the test, No. 39315-1-III State v. Sliger
but did not remove the strands of tobacco between his teeth. Based on Sliger’s denial of
a foreign substance, the trial court concluded that the State met its burden of producing
prima facie evidence that Sliger did not have a foreign substance in his mouth at the
beginning of the observation period.
We affirm. An officer can rely on a subject’s denial so long as the officer is not
otherwise aware of the presence of a foreign substance. Here, Sliger denied having any
foreign substances in his mouth, and when the officer checked, he did not see any foreign
substances. He did see strands of tobacco but did not consider them to be a foreign
substance. Nor did the trial court find that strands of tobacco were a foreign substance.
Thus, the trial court did not err in concluding that Sliger’s denial was prima facie
evidence that he did not have any foreign substances in his mouth. As the trial court
noted, admissibility is different from validity, and Sliger can still use evidence of the
tobacco strands to challenge the validity of the test at trial.
BACKGROUND
The admissibility of a breath test is governed by case law, statute, and regulations.
Specifically, RCW 46.61.506(4)(a) requires the State to produce prima facie evidence of
certain facts before a test can be admitted as evidence. One of the facts is evidence that
the person being tested “did not have any foreign substances, not to include dental work
or piercings, fixed or removable, in his or her mouth at the beginning of the fifteen-
minute observation period.” RCW 46.61.506(4)(a)(iii).
2 No. 39315-1-III State v. Sliger
On April 26, 2020, John Henry Sliger was involved in a dirt bike collision.
Deputy Mitchell Kahns was the officer dispatched to the scene. Once at the scene,
Deputy Kahns began asking Sliger questions about the incident, and Sliger admitted he
had consumed alcohol a few hours before the crash. Deputy Kahns noted that Sliger had
chewing tobacco in his mouth, but testified that Sliger took it out at the scene. After a
preliminary investigation, Deputy Kahns placed Sliger under arrest for driving while
under the influence and transported him to jail.
Once they arrived at the jail, Deputy Kahns began preparations to administer the
Draeger Breath Alcohol Test. Deputy Kahns asked Sliger if Sliger had anything in his
mouth, to which Sliger responded no. Deputy Kahns then checked Sliger’s mouth and
noted tiny strands of tobacco left in between a few of Sliger’s teeth. He later
characterized it as “debris.” Rep. of Proc. (RP) at 33. When asked if he saw any foreign
substances in Sliger’s mouth, Deputy Kahns testified no. He indicated that he made note
of the tobacco strands in his report because “they were there,” but did not have Sliger
remove the strands before administering the test.1 RP at 19.
1 In his narrative report, Deputy Kahns indicated that he did not observe any foreign substances in Sliger’s mouth, but in his DUI report, Deputy Kahns checked the box “yes” on whether any foreign substances were found and then provided an explanation: “tiny tobacco strands stuck in teeth.” CP at 35. During the motion to suppress, Deputy Kahns testified that he did not believe, based on his training, that tobacco strands qualified as a foreign substance, but wanted to make a note of the strands so he checked the “yes” box on whether there were foreign substances.
3 No. 39315-1-III State v. Sliger
Sliger filed a motion to suppress the results of the breath test, arguing that the
State would not be able to meet the foundational requirements for admission. In addition
to the arresting officer, the State called Trooper John Axtman, a breath test technician and
instructor. Trooper Axtman testified that it was important for the machine to measure
alcohol from the lungs, rather than mouth alcohol. One way to ensure that there is no
mouth alcohol is to ask the suspect if they have anything in their mouth and then check
the mouth for foreign substances. In addition, the machine’s slope detector tests for
mouth alcohol. If the slope detector rises too quickly, then mouth alcohol is present and
the machine will register an invalid sample.
The prosecutor then asked Trooper Axtman about the effects of tobacco on the
test:
[Prosecutor] —is chewing tobacco before the 15 minutes and they remove it, are you gonna have any concerns with, you know, if they don’t brush their teeth before they do the test? [Axtman]: If they removed it, no. Now, if they didn’t remove it then, yeah, I’d have some heartache on it if they left a lump of tobacco in there. [Prosecutor]: Okay. And you just now said a lump of tobacco. If somebody’s got, you know, some flecks on their teeth, is that going to cause you the same heartache as a lump of tobacco? [Axtman]: No, it’s not. I used to chew. And sometimes it can be difficult to get those little tiny grits out of your teeth, even after rinsing it. So, again, you do the best with what you have. ....
4 No. 39315-1-III State v. Sliger
[Prosecutor]: Would you consider, you know, having a piece of bread stuck between your teeth or a piece of tobacco flake on your teeth to be foreign substances that would render this invalid, an invalid sample? [Axtman]: I’d have no—I’d have no concerns with the breath test. With, again, with very small amounts like that. [Prosecutor]: Uh-huh. [Axtman]: Now, again, if there were large amounts I would have a concern. [Prosecutor]: Okay. What do you consider a large amount? [Axtman]: Well, for tobacco purposes, a lump of tobacco in there. [Prosecutor]: Okay. Why is that? [Axtman]: Because it technically is a foreign substance. [Prosecutor]: Okay. But what is it about having that in there that’s going to affect the breath test? [Axtman]: There’s case—there’s case studies showing that—if you really want me to get into it I can get into the case studies -- but showing the effects or lack of for the breath testing.

be required to remove the foreign substance.
Following this testimony, the trial court denied the motion to suppress. The court
concluded that the State had introduced prima facie evidence that Sliger did not have any
5 No. 39315-1-III State v. Sliger
foreign substances in his mouth based on Sliger’s denial. It explained that evidence that
strands of tobacco remained between Sliger’s teeth could be used at trial to challenge the
validity of the test. Following the hearing, the court entered the following relevant
findings and conclusions:
[FOF] 2. At the scene of the arrest, Mr. Sliger had chewing tobacco in his mouth but removed it at the scene prior to transport to the Stevens County Jail. [FOF] 6. Prior to the breath test, Deputy Kahns asked Mr. Sliger if he had any substances in his mouth and Mr. Sliger said “no.” [FOF] 7. Prior to the breath test, Deputy Kahns checked Mr. Sliger’s mouth for foreign substances. He noted tiny strands of tobacco between Mr. Sliger’s teeth. Tobacco is a foreign substance, but the tobacco strands were not removed. ....
[COL] 6. The statutory test for admissibility requires strict compliance. Deputy Kahns [sic] asked Mr. Sliger if he had any foreign substances in his mouth and received a denial. The State has met the burden of providing prima facie evidence that Mr. Sliger did not have any foreign substances in his mouth at the beginning of the fifteen-minute observation period, based solely on Mr. Sliger’s denial that he had any foreign substances in his mouth. Therefore, the Draeger BAC results are admissible at trial.

Sliger challenges finding of fact 2 and conclusion of law 6.
6 No. 39315-1-III State v. Sliger
ANALYSIS
This case boils down to whether strands of tobacco in a suspect’s teeth constitute a
foreign substance that must be removed before administering a breath test. Sliger appeals
the trial court’s denial of his motion to suppress the breath test result, arguing that the
State failed to meet its burden of showing the test was admissible under RCW
46.61.506(4)(a). In particular, Sliger challenges the trial court’s finding that he removed
the tobacco in his mouth prior to the test and the court’s conclusion that his denial of
having anything in his mouth was sufficient to meet the State’s burden of showing that
“the person tested did not have any foreign substances . . . in his or her mouth.”
Appellant’s Br. Appendix at 31. He contends that the finding and conclusion are
inconsistent with the finding that strands of tobacco remained in between his teeth.
Written findings entered after a CrR 3.6 suppression hearing will be upheld if they
are supported by substantial evidence in the record. State v. Hill, 123 Wn.2d 641, 644,
870 P.2d 313 (1994). Evidence is considered “substantial” if it is “sufficient to persuade
a fair-minded, rational person of the truth of the finding.” State v. Mendez, 137 Wn.2d
208, 214, 970 P.2d 722 (1999). Conclusions of law are reviewed de novo. State v.
Garvin, 166 Wn.2d 242, 249, 207 P.3d 1266 (2009).
Construction of a statute is a question of law reviewed de novo. State v. Engel,
166 Wn.2d 572, 576, 210 P.3d 1007 (2009). When interpreting a statute, our
“fundamental objective is to ascertain and give effect to the legislature’s intent.”
7 No. 39315-1-III State v. Sliger
Lenander v. Dep’t of Ret. Sys., 186 Wn.2d 393, 405, 377 P.3d 199 (2016). Where the
language of a statute is clear, the legislature’s intent will be derived from the plain
language of the statute. Engel, 166 Wn.2d at 578. When a term is not defined, we may
result to the common law definition. Id. at 578-79. We should avoid an interpretation
that produces an absurd result. Id. at 579.
When the government moves to admit the results from a breath test, it must
produce prima facie evidence that the criteria set forth in RCW 46.61.506(4) have been
met. “For purposes of this section, ‘prima facie evidence’ is evidence of sufficient
circumstances that would support a logical and reasonable inference of the facts sought to
be proved.” RCW 46.61.506(4)(b). Moreover, in assessing whether the foundational
evidence is sufficient, the court is required to assume the truth of the government’s
evidence and construe reasonable inferences in favor of the government. Id. Once the
foundational requirements are met and the test results are admitted, a defendant may
attack the test results in a particular case by challenging the reliability or validity of the
results. City of Seattle v. Allison, 148 Wn.2d 75, 80, 59 P.3d 85 (2002).
RCW 46.61.506(4)(a) sets forth eight criteria that the State must show for a breath
test to be admissible. For purposes of this appeal, the only contested criteria is whether
the State has produced prima facia evidence that “[t]he person being tested did not have
any foreign substances . . . in his or her mouth at the beginning of the fifteen-minute
observation period.” RCW 46.61.506(4)(a)(iii) (emphasis added).
8 No. 39315-1-III State v. Sliger
In conformity with the requirements of RCW 46.61.506(3), the state toxicologist
has adopted regulations that provide the approved methods for administering the breath
test. The regulations provide two alternative methods for determining if a foreign
substance is present:
A determination as to whether a subject has a foreign substance in his or her mouth will be made by either an examination of the mouth or a denial by the person that he or she has any foreign substances in their mouth.
WAC 448-16-040(1). This methodology does not require or guarantee complete
accuracy. Instead, if interference is detected, or if the test records an invalid sample, the
testing must start over after determining that the subject does not have foreign substances
in their mouth. WAC 448-16-040(2), (3).
While the regulations only require the officer to use one method for determining
the absence of a foreign substance, here Officer Kahns employed both methods. Nothing
in the regulations precludes the use of both methods. On appeal, defense counsel admits
that if the deputy had only asked Sliger about foreign substances, without checking his
mouth, then Sliger’s negative answer would have been sufficient to meet the requirement
of WAC 448-16-040. Appellant’s Br. at 16. But Sliger argues that because the deputy
also checked his mouth, and observed strands of tobacco, the evidence does not support
the trial court’s finding that Sliger had removed the tobacco from his mouth, and the trial
court erred in concluding that the deputy could rely on Sliger’s answer.
9 No. 39315-1-III State v. Sliger
We agree that an officer who is aware that a subject has a foreign substance in
their mouth cannot ignore this information even if a subject denies having anything in
their mouth. The BAC technician who testified at the motion to suppress agreed with
this. In this respect, the court’s conclusion, that Sliger’s denial was sufficient to meet the
State’s burden, is correct so long as Deputy Kahns was not otherwise aware of a foreign
substance in Sliger’s mouth.
Sliger does not challenge the trial court’s finding that tobacco is a foreign
substance, but he does challenge the court’s finding that Sliger removed the tobacco from
his mouth because strands of tobacco remained. We conclude that the evidence and the
law support a distinction between a lump of chewing tobacco and tiny strands of tobacco
for purposes of determining admissibility of a breath test.
The trial court’s findings distinguished between tobacco and strands of tobacco.
While the court found that tobacco was a foreign substance, and this substance had been
removed, the court did not find that strands of tobacco would qualify as a foreign
substance. The court’s distinction between tobacco and tiny strands of tobacco for
purposes of finding a foreign substance is supported by the evidence.2 Not only did the
technician testify that strands of tobacco would not adversely affect the test, but he also
2 While it would have been helpful if the court had made an explicit finding that strands of tobacco did not constitute a foreign substance, “where a trial court does not make a finding of fact, we presume a finding against such fact.” Recreational Equip., Inc. v. World Wrapps Nw., Inc., 165 Wn. App. 553, 565, 266 P.3d 924 (2011).
10 No. 39315-1-III State v. Sliger
testified that if the substance were of sufficient quantity to retain mouth alcohol, the
machine would invalidate the test. Deputy Kahns testified that he did not believe the
strands of tobacco to be a foreign substance.
Regardless of the court’s findings, Sliger contends that RCW 46.61.506(4)(a)(iii)
requires the State to produce prima facie evidence that the subject did not have any
foreign substance in his mouth at the beginning of the observation period. His argument
focuses on the word “any” without attempting to define a “foreign substance.”
A “foreign substance” is defined as a substance that “adversely affect[s] the
accuracy of test results.” City of Sunnyside v. Fernandez, 59 Wn. App. 578, 582, 799
P.2d 753 (1990). This definition leaves room for a substance such as tobacco to be
considered a foreign substance based on the amount of the substance present. In other
words, tobacco only becomes a foreign substance when it is present in an amount
sufficient to adversely affect the test. Reading the statute otherwise would lead to absurd
results. If we were to hold that the presence of any amount of a substance that is foreign
to the mouth renders a test inadmissible, then in theory the microscopic presence of any
such substance would impact admissibility. Such a result is not required by the
regulations or the statute.
The trial court’s finding that Sliger had removed the foreign substance, tobacco,
from his mouth is supported by the evidence. Because Deputy Kahns was not otherwise
aware of any other foreign substances, the trial court did not err in concluding that
11 No. 39315-1-III State v. Sliger
Sliger’s denial was prima facie evidence that he did not have any foreign substances in
his mouth.
We affirm the trial court’s denial of Sliger’s motion to suppress the results of the
breath test and remand for further proceedings.
A majority of the panel has determined this opinion will not be printed in the
Washington Appellate Reports, but it will be filed for public record pursuant to RCW
2.06.040.
