SUMMARY
May 6, 2021

2021COA62

No. 18CA1557, People v. Ambrose — Crimes — DWAI; Vehicles
and Traffic — Alcohol and Drug Offenses — Certification of
Breath Test Instruments; Constitutional Law — Sixth
Amendment — Confrontation Clause

As a matter of first impression in Colorado and consistent with

other jurisdictions, a division of the court of appeals holds that a

“working order” certificate generated by an Intoxilyzer 9000 (I-9000)

machine is not testimonial and does not implicate a defendant’s

confrontation rights. The division concludes that such certificates

are admissible if they comply with the requirements of section 42-4-

1303, C.R.S. 2020, and that evidence related to the machine’s

reliability goes to the weight of the evidence, not its admissibility.

The division also concludes that a deputy’s opinion that the I-

9000 was working properly constitutes an expert opinion that was
erroneously admitted as a lay opinion, but that any error was

harmless.

In a prior opinion, People v. Ambrose, 2020 COA 112, the

division affirmed the defendant’s felony DWAI conviction holding

that his prior convictions were sentence enhancers, not an element

of the offense. Our supreme court returned the case to the division

to issue a new opinion in light of its holding in Linnebur v. People,

2020 CO 79M. Consistent with that decision, the division reverses

Mr. Ambrose’s felony DWAI conviction and remands the case for

either a new trial or resentencing on the misdemeanor, at the

prosecution’s discretion.

The division rejects the contentions that the trial court

erroneously (1) found the arresting officer had reasonable

suspicion; (2) failed to remove a biased juror for cause; and (3)

denied an evidentiary hearing on the admissibility of the breath test

result.

Finally, because we are reversing the felony DWAI conviction

and the trial court will impose a new sentence on any future

conviction, we need not address the persistent drunk driver

surcharge claim.

General, Denver, Colorado, for Plaintiff-Appellee

State Public Defender, Denver, Colorado, for Defendant-Appellant
¶1 In this impaired driving case, we are asked to decide a novel

issue related to the Intoxilyzer 9000 machine (I-9000). Each time

the I-9000 is used to measure a person’s breath alcohol content

(BAC), it generates a BAC result and a separate document that

certifies the machine is working properly and is certified for use

during a specific range of dates. The question presented here is

whether that “working order” certificate is testimonial and

implicates a defendant’s confrontation rights under the Sixth

Amendment to the United States Constitution. We conclude,

consistent with every state to have considered this issue, that this

certificate is not testimonial and, thus, does not implicate the

Confrontation Clause.

¶2 Defendant, William Edward Ambrose, appeals the judgment

entered after a jury convicted him of felony driving while ability

impaired (DWAI). He contends that the trial court reversibly erred

by (1) finding the arresting officer had reasonable suspicion; (2)

failing to remove a biased juror for cause; (3) refusing to submit the

issue of prior alcohol convictions to the jury to determine beyond a

reasonable doubt; (4) failing to grant an evidentiary hearing on the

admissibility of the I-9000 breath test results; (5) allowing a

1
 deputy’s expert testimony disguised as lay testimony concerning the

I-9000’s operations; (6) admitting the I-9000 certificate document

contrary to the relevant statute’s requirements and in violation of

his confrontation rights; and (7) imposing the persistent drunk

driver surcharge after sentencing in violation of his right to be free

from double jeopardy.

¶3 The supreme court vacated our opinion and remanded the

case for reconsideration in light of its decision in Linnebur v. People,

2020 CO 79M. Ambrose v. People, (Colo. No. 20SC698 Apr. 12,

2021) 2021 WL 1392194 (unpublished order). In Linnebur, the

supreme court held that the requirement of three or more prior

qualifying offenses is an element of felony DWAI that must be found

by a jury beyond a reasonable doubt. Linnebur, ¶¶ 2, 31.

Consistent with that decision, we reverse Mr. Ambrose’s felony

DWAI conviction and remand the case for either a new trial or

resentencing on the misdemeanor, at the prosecution’s discretion.

Because we reverse the judgment, we need not resolve Mr.

Ambrose’s persistent drunk driving surcharge claim and do not

address it further. See People v. Curtis, 2014 COA 100, ¶ 12

2
 (applying the principle of judicial restraint: “[I]f it is not necessary to

decide more, it is necessary not to decide more”) (citation omitted).

¶4 While we recognize that many of Mr. Ambrose’s remaining

contentions may not arise if the case is retried, we elect to address

these contentions because they may bear on whether the

misdemeanor conviction can stand if the prosecution chooses not to

seek a retrial of the felony. See People v. Marston, 2021 COA 14, ¶

2.

I. Factual Background

¶5 While on patrol and stopped in a highway pullout, Deputy

Corey Dilka saw a car pass him with a dimly lit left taillight. He

followed the car and as he got closer, he no longer saw any light

coming from the left taillight. Instead, he saw a steady white light.

Believing a traffic infraction had occurred, Deputy Dilka activated

his emergency lights, pulled the vehicle over, and contacted Mr.

Ambrose, who was driving.

¶6 While speaking with Mr. Ambrose, Deputy Dilka detected “an

odor of an unknown alcoholic beverage” coming from the vehicle

and saw that Mr. Ambrose’s eyes were glassy. After learning from

dispatch that Mr. Ambrose had active restraints on his driver’s

3
 license in other states, Deputy Dilka asked Mr. Ambrose to step out

of the car. Deputy Dilka again detected an odor of an alcoholic

beverage, this time coming from Mr. Ambrose.

¶7 Mr. Ambrose subsequently consented to performing voluntary

roadside maneuvers. After observing several clues of impairment,

Deputy Dilka placed Mr. Ambrose under arrest on suspicion of

driving under the influence. Mr. Ambrose agreed to a breath test,

which revealed a BAC of 0.063.

¶8 As relevant here, prosecutors charged Mr. Ambrose with a

count of felony DWAI (felony fourth offense) and driving without a

valid license.1 The jury convicted him of DWAI and acquitted him of

driving without a valid license. In a bench trial, the trial court

found that the prosecution had established the existence of three

prior convictions for alcohol-related offenses, thereby elevating Mr.

Ambrose’s DWAI conviction from a misdemeanor to a class 4 felony.

The trial court sentenced Mr. Ambrose to three years in community

corrections, but it said nothing about the persistent drunk driver

1 The People initially charged Mr. Ambrose with failure to provide
insurance and failure to display proper taillights as well. Before
trial, the prosecution dismissed the taillight violation, and during
trial, the court dismissed the failure to provide insurance count.

4
 surcharge at the hearing. The mittimus, however, reflected this

surcharge.

II. Reasonable Suspicion

¶9 Mr. Ambrose first contends the trial court erroneously found

that Deputy Dilka had reasonable suspicion to initiate a traffic stop.

He moved to suppress evidence of impairment obtained as a result

of the stop, but the trial court denied his motion. Considering the

totality of the circumstances, we discern no error.

A. Standard of Review and Relevant Law

¶ 10 A trial court’s ruling on a motion to suppress presents a mixed

question of fact and law. People v. Montante, 2015 COA 40, ¶ 59.

We defer to the court’s findings of fact if they are supported by the

record, and we review de novo the court’s legal conclusions. Id.

¶ 11 The Fourth Amendment to the United States Constitution

protects against unreasonable searches and seizures. “A

warrantless search and seizure is unreasonable unless it is justified

by one of the few, specifically established exceptions to the Warrant

Clause of the Fourth Amendment.” People v. Revoal, 2012 CO 8,

¶ 10.

5
¶ 12 An investigatory stop is permitted if the officer has “a

reasonable suspicion that criminal activity has occurred, is taking

place, or is about to take place.” Id. (citation omitted). “Reasonable

suspicion is both a qualitatively and quantitatively lower standard

than probable cause. That is, it can be supported both by less

information and by less reliable information than is necessary to

establish probable cause.” People v. King, 16 P.3d 807, 813 (Colo.

2001).

¶ 13 To determine whether an investigatory stop is valid, a court

must consider the facts and circumstances known to the police

officer at the time of the stop. Revoal, ¶ 11. To justify an

investigatory stop, an officer “must be able to point to specific and

articulable facts which, taken together with rational inferences from

those facts, reasonably warrant that intrusion.” Terry v. Ohio, 392

U.S. 1, 21 (1968). An “unarticulated hunch” is not sufficient.

Revoal, ¶ 11 (citation omitted). This inquiry focuses on an

“objective analysis of whether a reasonable, articulable suspicion

exists and not on the subjective intent of the officer.” People v.

Reyes-Valenzuela, 2017 CO 31, ¶ 12.

6
 B. Analysis

¶ 14 Here, Deputy Dilka had reasonable suspicion to stop Mr.

Ambrose for a suspected motor vehicle equipment violation.

Section 42-4-215(6), C.R.S. 2020, provides that “[a]ny motor vehicle

may be equipped with not more than two back-up lamps either

separately or in combination with other lamps, but no such back-

up lamp shall be lighted when the motor vehicle is in forward

motion.” Deputy Dilka testified that once he got behind Mr.

Ambrose’s car, he saw that the left taillight emitted a steady white

light instead of a red light. The officer’s observation of a white light

coming from the area where the backup light was located was

enough to justify the stop. See People v. Chavez-Barragan, 2016

CO 16, ¶ 10 (“Suspicion of even a minor traffic offense can provide

the basis for a stop.”).

¶ 15 We are not persuaded by Mr. Ambrose’s argument that the

stop was unreasonable because Deputy Dilka testified that he

stopped Mr. Ambrose for a different equipment violation under

section 42-4-206(1), C.R.S. 2020. That statute says that “every

vehicle registered in this state and manufactured or assembled after

January 1, 1958, must be equipped with at least two tail lamps

7
 mounted on the rear.” § 42-4-206(1). Mr. Ambrose argues that

because his vehicle displayed Wisconsin plates and presumably was

not registered in Colorado, Deputy Dilka did not have a reasonable

articulable suspicion to initiate a traffic stop. We disagree.

¶ 16 As our supreme court has reiterated, the reasonable suspicion

standard is an objective one, and is not one that focuses on the

officer’s subjective intent. See Reyes-Valenzuela, ¶ 12. Deputy

Dilka’s observation of a continually illuminated white light supports

an objective belief that Mr. Ambrose’s car may have had a back-up

light that was lit even though the vehicle was moving forward,

contrary to section 42-4-215(6) (“[N]o such back-up lamp shall be

lighted when the motor vehicle is in forward motion.”). Indeed, a

police officer does not have to observe a traffic violation to initiate a

stop; the officer can also initiate a stop if the officer has a

“reasonable articulable suspicion that a traffic or equipment

violation has occurred or is occurring.” People v. Johnston, 2018

COA 167, ¶ 20 (quoting United States v. Botero-Ospina, 71 F.3d

783, 787 (10th Cir. 1995)). The existence of out-of-state plates does

not alter the analysis because section 42-4-215(6) does not require

the vehicle to be registered in Colorado.

8
¶ 17 Since we conclude that Deputy Dilka had a reasonable

suspicion to initiate a traffic stop under section 42-4-215(6), we

need not address Mr. Ambrose’s remaining arguments concerning

the mistake of law exception. See Curtis, ¶ 12.

III. Biased Juror

¶ 18 Mr. Ambrose next contends that the trial court erroneously

denied his challenge for cause to Juror C.J. Specifically, he faults

the court for failing to rehabilitate or otherwise ensure Juror C.J.’s

ability to be fair and impartial after she indicated (by raising her

hand) that (1) she agreed it was always wrong to drive after having a

drink and (2) a person accused of doing something wrong should

explain himself or herself. Based on our consideration of the entire

voir dire, we discern no reversible error with respect to the first

point, and we decline to consider the second point because it is

raised for the first time on appeal.

A. Additional Facts

¶ 19 The trial court began voir dire by reading pertinent rules of law

(including the presumption of innocence and the burden of proof)

and inquiring about the statutory disqualifications for jury service.

9
 At the end of this process, the court asked, “Is there anyone who

wants to bring anything to my attention? No hands are raised.”

¶ 20 The prosecutor then inquired about the prospective jurors’

ability to follow the law, asking whether anyone would just say to

themselves, “I’m going to go ahead and, and just say this shouldn’t

be a crime” or “I’m not going to follow what I don’t believe in.” Juror

C.J. did not raise her hand.

¶ 21 The prosecutor then asked, “Has anyone here ever had to take

away somebody’s keys?” Juror C.J. raised her hand and explained

that she once worked as a bartender and had taken patrons’ keys

away. When asked what helped her make that decision, Juror C.J.

responded, “Observation and erring on the side of safety.”

¶ 22 No prospective jurors raised their hands after the prosecutor

asked them whether they felt so strongly about alcohol that they

necessarily would render a guilty verdict, or whether anyone did not

trust law enforcement.

¶ 23 Defense counsel began voir dire by asking the panel members

if they “think[] that it’s never okay or not okay to have a beer and

then go drive a car?” Several prospective jurors, including Juror

10
C.J., raised their hands. Counsel then followed up with a different

juror, Juror R.N., in the following colloquy:

[Counsel]: So [Juror R.N.], I want to ask you a
question. If you’re told that there’s a rule in
Colorado, a law in Colorado that in some
circumstances it is legal, it is not illegal to
have a drink and then get in a car. That
sounds to be contrary to what your life beliefs
are. Is that fair?

[Juror R.N.]: Yes.

[Counsel]: Okay. And if you were asked to
raise your hand and swear an oath that you
could follow that rule, is that something that
you would struggle with?

[Juror R.N.]: Probably —

[Counsel]: Okay.

[Juror R.N.]: — yeah.

[Counsel]: And thank you for your honesty.
And again, this is what this whole process is
about. Is talking through stuff like that. So I
really appreciate that. Is it fair to say some
little defense lawyer isn’t going to change your
mind about that thinking[?] You’ve had this
belief for 40 years.

[Juror R.N.]: Yes.

[Counsel]: Okay. Fair to say that whatever he
says, he’s not going to change your mind about
your beliefs.

[Juror R.N.]: No.

11
 [Counsel]: And even the Judge. Fair to say
that if she tells you otherwise, these are your
thoughts right now.

[Juror R.N.]: No, because mine’s based on
actually a higher calling. My Christianity. I, I
believe that you’re responsible for your own
actions. Anybody.

[Counsel]: Fair enough. And I think that’s —

[Juror R.N.]: (Indiscernible).

[Counsel]: -- that’s very commendable. And so
this is something that goes even deeper to you.
It’s —

[Juror R.N.]: Yes.

....

[Counsel]: Okay. Well, I appreciate that, Juror
R.N. Who here agrees with [Juror R.N.] that if
they’re told that rule, that in some
circumstances you can drink and you can
drive a car, it’s not illegal, that conflicts with
what you believe? Who agrees with [Juror
R.N.]?

(Emphasis added.) Juror C.J. did not raise her hand in response to

this last question. And defense counsel never questioned Juror

C.J. further concerning her earlier raised hand.

¶ 24 Later, defense counsel asked about a defendant’s right to

remain silent and said, “If you’re accused of doing something

wrong, who thinks you should explain yourself? I see some head

12
 nodding. I want to see a hand raised.” Juror C.J. was among those

jurors who raised their hands, but defense counsel never asked her

any further questions.

¶ 25 During the subsequent bench conference, defense counsel

said, “I challenge [C.J.] for cause on the same grounds [as R.N.]. I

did not get as much information from her, but she did raise her

hand and agree with [R.N.] with the impairment, so I make the

same constitutional and statutory motion for cause on [C.J.].”

Defense counsel did not challenge Juror C.J. based on the

defendant’s right to remain silent.

¶ 26 Concerning Juror C.J., the prosecutor responded:

[C.J.], the mere fact that she agreed with some
other people [sic]. There was no statement,
[that she] could not follow the law. There was
no ultimate statement that actually conflicts or
would bring about [sic]. It’s just [defense
counsel’s] gut feeling that he thinks maybe she
couldn’t. She needs to actually be confronted
with the, the idea that she couldn’t follow the
law and say that she couldn’t follow the law.
And that was not the case with [C.J.].

¶ 27 The trial court agreed with the prosecution and said:

With regard to [C.J.], while she raised her
hand in response to a question (indiscernible)
she was not specifically asked about
(indiscernible), nor did she specifically state

13
 [that] she would not follow the law. I can’t find
just by her — her raised [hand] that she is
subject to a cause challenge, to a valid cause
challenge (indiscernible). [The challenge to
C.J.] is denied.

¶ 28 After voir dire, both parties exercised peremptory challenges to

excuse several jurors. The defense did not exercise a peremptory

challenge to remove Juror C.J.

B. Standard of Review and Law

¶ 29 We will overturn a trial court’s ruling on a challenge for cause

only upon an affirmative showing that the court abused its

discretion, Carrillo v. People, 974 P.2d 478, 485 (Colo. 1999); that

is, only if there is no evidence in the record to support the ruling,

People v. Richardson, 58 P.3d 1039, 1042-43 (Colo. App. 2002).

This is a “very high standard of review” that accords deference to

the trial court’s superior ability to assess a potential juror’s

credibility, demeanor, and sincerity. People v. Young, 16 P.3d 821,

824 (Colo. 2001) (quoting Carrillo, 974 P.2d at 485-86); Morrison v.

People, 19 P.3d 668, 672 (Colo. 2000).

¶ 30 In determining whether a court abused its discretion in ruling

on a challenge for cause, we must review the entire voir dire of the

prospective juror. Carrillo, 974 P.2d at 486. If the trial court

14
 abused its discretion, we must conduct an “outcome-determinative”

analysis to determine whether the error warrants reversal, if the

defendant used a peremptory challenge to excuse the wrongful

juror. Abu-Nantambu-El, ¶ 22. However, if the defendant fails to

use a peremptory challenge to dismiss a biased juror, and the juror

serves on the jury, the erroneous seating of the biased juror is

structural error requiring reversal. See Richardson v. People, 2020

CO 46, ¶ 28.

¶ 31 To protect a defendant’s right to an impartial jury, a trial court

must excuse prejudiced or biased persons from the jury. See

§ 16-10-103(1)(j), C.R.S. 2020; Nailor v. People, 200 Colo. 30, 31-32,

612 P.2d 79, 80 (1980). “Actual bias is a state of mind that

prevents a juror from deciding the case impartially and without

prejudice to a substantial right of one of the parties.” People v.

Macrander, 828 P.2d 234, 238 (Colo. 1992), overruled on other

grounds by Novotny, 2014 CO 18.

¶ 32 When a prospective juror makes a statement evincing bias,

she may nonetheless serve if she agrees to set aside any

preconceived notions and make a decision based on the evidence

and the court’s instructions. People v. Phillips, 219 P.3d 798, 801

15
 (Colo. App. 2009). It is within the trial court’s discretion to accept a

juror’s statements that she would base her decision on the evidence

presented at trial. See Carrillo, 974 P.2d at 485.

¶ 33 A juror who initially misunderstands the law should not be

removed for cause if, after explanation and rehabilitative efforts, the

court believes that she can render a fair and impartial verdict based

on the instructions given by the judge and the evidence presented

at trial. People v. Clemens, 2017 CO 89, ¶ 16. The court must

examine the juror’s statements or silence in light of the totality of

the circumstances. Id. at ¶ 20. “[A] prospective juror’s silence in

response to rehabilitative questioning constitutes evidence that the

juror has been rehabilitated when the context of that silence

indicates that the juror will render an impartial verdict according to

the law and the evidence submitted to the jury at the trial.” Id. at ¶

19.

C. Preservation

¶ 34 The People concede that Mr. Ambrose preserved the first issue

related to the drinking and driving question. However, they argue

that defense counsel never challenged Juror C.J. for cause based

on the second question concerning the right to remain silent. Mr.

16
 Ambrose responds that he preserved both issues by asking Juror

C.J. to be excused for cause because she was biased. Because

defense counsel alleged bias only with regard to the first issue, and

never mentioned or argued Juror C.J.’s raised hand to the right to

remain silent question, we agree with the People that the first issue

is preserved, and the second issue is not.

¶ 35 If a party fails to raise a matter pertaining to the qualifications

and competency of a prospective juror before the jury is sworn in,

the matter “shall be deemed waived.” Crim. P. 24(b)(2). Hence,

when a party fails to preserve a for-cause challenge, the appellate

court will “decline to address for the first time on appeal a different

ground that was not clearly brought to the attention of the trial

court and opposing counsel.” People v. Coughlin, 304 P.3d 575, 580

(Colo. App. 2011). Because defense counsel failed to preserve a

challenge to Juror C.J. based on the right to remain silent question

before the jury was sworn, we conclude that it is waived and decline

to consider it. See People v. Cevallos-Acosta, 140 P.3d 116, 122

(Colo. App. 2005) (the “defendant abandoned his challenge for

cause to [a prospective juror] by failing to [renew his] request that

the trial court grant or deny [the challenge] before exercising a

17
 peremptory challenge to excuse her”); People v. Coleman, 844 P.2d

1215, 1218 (Colo. App. 1992) (declining to address the defendant’s

for-cause challenge on the grounds of bias “because defendant did

not present the issue of any actual, or implied, prejudice in the trial

court,” but instead challenged the juror on another basis).

D. Analysis

¶ 36 Based on the record before us, we are satisfied that the trial

court’s decision to deny Mr. Ambrose’s challenge for cause was not

an abuse of discretion. Although Juror C.J. raised her hand in

response to defense counsel’s question concerning whether it was

“never okay” to “have a beer and then go drive a car,” she did not

raise her hand at the conclusion of Juror R.N.’s questioning when

counsel asked whether any of the jurors agreed with Juror R.N.

And defense counsel did not further question Juror C.J. concerning

an inability to be fair. The absence of this further questioning,

when considered with the absence of raised hands to the

prosecutor’s questions about the panel’s ability to be fair and

impartial, leaves a record containing no evidence that Juror C.J.

was unable to be fair and impartial, or that she would be unable to

follow the law. Consequently, Juror C.J. displayed no bias or

18
 enmity against Mr. Ambrose, and we discern no error in the court’s

ruling denying Mr. Ambrose’s challenge for cause.

IV. Felony DWAI Prior Convictions

¶ 37 Mr. Ambrose contends that because prior convictions under

section 42-4-1301(1)(b), C.R.S. 2020, transform a misdemeanor

conviction into a felony conviction, they constitute an element of the

felony offense that must be proved to a jury beyond a reasonable

doubt, rather than a sentence enhancer. Because we are bound by

our supreme court’s holding in Linnebur, we agree.

¶ 38 “An appellate court reviews a constitutional challenge to

sentencing de novo.” People v. Mountjoy, 2016 COA 86, ¶ 10, aff’d

on other grounds, 2018 CO 92M.

¶ 39 In Linnebur, ¶ 2, our supreme court held that prior convictions

used to elevate a misdemeanor DUI or DWAI to a felony constitute

an element of the crime that “must be proved to the jury beyond a

reasonable doubt,” and do not serve as a sentence enhancer that

may be proved by a preponderance of the evidence. Because the

trial court treated Mr. Dixon’s prior convictions as a sentence

enhancer, we must reverse his felony conviction. See id. at ¶ 32.

But, because the error did not affect Mr. Ambrose’s misdemeanor

19
 conviction, the prosecution may either seek resentencing on the

misdemeanor DWAI or it may retry the felony DWAI, in its

discretion. See id. If Mr. Ambrose raises a double jeopardy defense

on a retrial, the trial court must rule on that defense.

V. Shreck Hearing

¶ 40 Mr. Ambrose next contends that the trial court erroneously

admitted I-9000 evidence without first holding a hearing to assess

its reliability under People v. Shreck, 22 P.3d 68 (Colo. 2001). We

disagree.

A. Additional Facts

¶ 41 Before trial, Mr. Ambrose requested a hearing to determine the

reliability and relevance of the I-9000 device under Shreck.

Attached to his motion were numerous press articles describing

allegations that certain I-9000 certificates in Colorado had been

fraudulently obtained and generated. He also challenged the

I-9000’s inner workings and the reliability of the device’s underlying

science. The trial court found as follows:

Colorado Revised Statutes 42-4-1301 requires
courts to take judicial notice of the testing
methods and of the design and operation of
testing devices, as certified by the Colorado
Department of Public Health [and]

20
Environment to determine a person’s alcohol
level. As recognized by the Court in People v.
Bowers, 716 P.2d 471, Colorado Supreme
Court case from 1986. Once CDPHE certifies a
methodology of testing for a device, the Court
may take judicial notice of the reliability of the
methodology and the device without the
necessity for further proof.

So here, the statutory scheme in Colorado
provides that [if a] breath device and method
[are] certified by CDPHE, the Court is to take
judicial notice of [their] reliability. The burden
is on the prosecution at trial to determine that
the testing devices were certified, were in
proper working order, and operated by a
qualified person and operated within
substantial compliance with CDPHE
regulations. If those things are satisfied, the
results are admissible. Thomas v. People, 895
P.2d 1040, Colorado 1995.

I have reviewed the defendant’s motion for a
[Shreck] hearing on the reliability and
admissibility, and I’ve reviewed the attached
news articles and [Judge Taylor’s Order] out of
Gilpin [County] from last summer related to
the device issues that occurred around the
rollout of the [I-9000s] in 2013 and used by
CDPHE of an expired — or the signature of an
individual who no longer worked at that
department.

Notably in Judge Taylor’s conclusion was the
statement that if the People can show the
[I-9000] was in proper working order without
the instrument certificate that was the one
with the faulty signature, the BAC results may
be admissible. Judge Taylor’s Order, while [it

21
 is] interesting and instructive with regard to
the [I-9000] certification process and the
inadmissibility in the context of that case of an
instrument certificate, it did not address
whether a defendant is entitled to a [Shreck]
hearing on the Intoxilyzer.

Here, I do find that the breath tests in the
Intoxilyzer are not a new or novel science, such
that the Court needs to hold an evidentiary
hearing to address the reliability of the
science. Certainly[,] the case law with regard
to the admissibility about breath tests is from,
for example, Bowers came out in 1986,
Thomas came out in 1995, so we’re talking
about 25, 30 years of information regarding
the reliability of breath testing. I cannot find
that it’s a new or novel science.

I find that the admissibility and reliability of
the breath test is an issue for trial being the
prosecution must put on sufficient evidence,
as I said before, that the device was certified,
proper working order, operated by a qualified
person and in substantial compliance with
CDPHE regulations. The defendant will be
afforded the ability to object both to the
admission based on the record at trial and to
cross-examine . . . or present other evidence
that may attack the weight the jury gives
[indiscernible] evidence. But the defendant’s
request for a [Shreck] hearing on the breath
testing device in this case is denied.

¶ 42 The prosecutor later endorsed Deputy Dilka as an expert in

standard sobriety roadside maneuvers and the operation and

functionality of the I-9000 device. Mr. Ambrose objected to the

22
 endorsement as untimely and reiterated his concerns under Shreck.

At a subsequent hearing, defense counsel explained that the

endorsement “calls into question how the Court could rule on a

Shreck motion regarding the . . . machine.” The court did not

readdress the Shreck issue but, instead, offered the defense a

continuance of the trial for up to one month to endorse its own

expert. The defense did not request a continuance.

B. Legal Framework and Standard of Review

¶ 43 CRE 702 governs the admissibility of expert testimony. It

states:

If scientific, technical, or other specialized
knowledge will assist the trier of fact to
understand the evidence or to determine a fact
in issue, [then] a witness qualified as an expert
by knowledge, skill, experience, training, or
education, may testify thereto in the form of an
opinion or otherwise.

¶ 44 Scientific evidence is admissible under CRE 702 if it is both

relevant and reliable. Shreck, 22 P.3d at 77; People v. Friend, 2014

COA 123M, ¶ 28, aff’d in part and rev’d in part, 2018 CO 90. In

determining the admissibility of expert testimony, the trial court

conducts a Shreck analysis, which requires the proponent to show

that (1) the scientific principles at issue are reasonably reliable; (2)

23
 the witness is qualified; (3) the testimony would be helpful to the

jury; and (4) the evidence satisfies CRE 403. People v. Rector, 248

P.3d 1196, 1200 (Colo. 2011); Friend, ¶ 28. The purpose of this

inquiry is to determine whether the proffered evidence is reliable

and relevant, and for the trial court — acting as gatekeeper — to

prevent the admission of “junk” science. People v. Wilson, 2013

COA 75, ¶ 22; Estate of Ford v. Eicher, 220 P.3d 939, 942 (Colo.

App. 2008), aff’d, 250 P.3d 262 (Colo. 2011). The trial court’s

reliability inquiry should be “broad in nature and consider the

totality of the circumstances” specific to each case. Shreck, 22 P.3d

at 77.

¶ 45 When a party requests a Shreck analysis, the court may, in its

discretion, determine whether an evidentiary hearing would be

helpful. Rector, 248 P.3d at 1201. However, the trial court is not

required to conduct a hearing if it “already has sufficient

information to make specific findings under Shreck.” People v.

Campbell, 2018 COA 5, ¶ 41 (citation omitted). “Concerns about

conflicting theories or the reliability of scientific principles go to the

weight of the evidence, not its admissibility.” Id. at ¶ 42 (citing

Estate of Ford, 250 P.3d at 269). These concerns are mitigated by

24
 vigorous cross-examination, presentation of contrary evidence, and

careful instruction on the burden of proof. Shreck, 22 P.3d at 78.

¶ 46 “We review a trial court’s evidentiary ruling for an abuse of

discretion.” Campbell, ¶ 38. The trial court abuses its discretion

when its ruling is “manifestly arbitrary, unreasonable, or unfair.”

Id. (citation omitted). And we review any error in denying a Shreck

hearing for nonconstitutional harmless error. Wilson, ¶ 24. An

error is harmless if a reviewing court can say with fair assurance

that, in light of the record as a whole, the error did not

substantially influence the verdict or impair the trial’s fairness. Id.

¶ 47 Section 42-4-1301(6)(c) provides that

(I) . . . [the trial court] shall take judicial notice
of methods of testing a person’s alcohol or
drug level and of the design and operation of
devices, as certified by the department of
public health and environment, for testing a
person’s blood, breath, saliva, or urine to
determine such person's alcohol or drug
level. . . .

(II) Nothing in this paragraph (c) prevents the
necessity of establishing during a trial that the
testing devices used were working properly and
were properly operated. Nothing in this
paragraph (c) precludes a defendant from
offering evidence concerning the accuracy of
testing devices.

25
 (Emphasis added.)

¶ 48 In People v. Bowers, our supreme court stated that “[b]reath

tests to determine the concentration of alcohol in a suspect’s breath

have long been recognized as valid scientific evidence.” 716 P.2d

471, 473 (Colo. 1986). The court also concluded that the statute

delegated authority to the Board of Health (which was later replaced

by the Colorado Department of Public Health and Environment

(CDPHE)) to “prescribe scientifically valid procedures for chemical

testing that will not only ensure safety in the testing process

but . . . will [also] provide sufficient reliability to the testing method

as to avoid the necessity of formal evidentiary proof on this aspect

of the testing process.” Id. at 474. The requirement for courts to

take judicial notice of the methods of testing a person’s alcohol

content means “[t]he legislature obviously believed that the testing

methods prescribed in the rules of [CDPHE] would be reasonably

reliable, thus justifying the court in taking judicial notice of the

testing method and thereby dispensing with the requirement of

formal proof on that matter.” Id.

26
 C. Analysis

¶ 49 We discern no abuse of discretion in the trial court’s denial of

a Shreck hearing, for two reasons. First, by employing the

mandatory word “shall,” section 42-4-1301(6)(c)(I) expressly

instructs courts to take judicial notice of the methods of testing a

person’s alcohol level as certified by CDPHE. People v. Dist. Court,

713 P.2d 918, 921 (Colo. 1986) (noting that the Colorado Supreme

Court “has consistently held that the use of the word ‘shall’ in a

statute is usually deemed to involve a mandatory connotation”).

Second, the record reflects that the I-9000 machine used in this

case was certified by CDPHE,2 and Deputy Dilka testified that the

machine was working properly.

¶ 50 We are not persuaded that the news articles attached to Mr.

Ambrose’s motion relating to alleged fraudulent certification of other

I-9000 machines require a different result. These issues go to the

weight of the evidence and not its admissibility and are properly

explored through cross-examination or the presentation of other

2We note that Mr. Ambrose challenges separately whether the I-
9000 used in this case was in fact certified by CDPHE because the
certificate lacked a signature. We address that contention below.

27
 evidence. See Shreck, 22 P.3d at 78. Moreover, neither the statute

nor the trial court’s order precluded Mr. Ambrose from introducing

evidence at trial challenging the reliability of breath tests. See § 42-

4-1301(6)(c)(II).

¶ 51 Further, we are not convinced that the prosecution’s late

endorsement of Deputy Dilka as an expert witness necessitates a

different result. Mr. Ambrose does not separately challenge the

timeliness of the endorsement, so we do not consider it further.

People v. Plancarte, 232 P.3d 186, 193 (Colo. App. 2009) (declining

to consider an issue defendant did not raise in his opening brief).

And, the prosecutor never qualified Deputy Dilka as an expert at

trial. Finally, the trial court offered the defense a reasonable

remedy to any late endorsement — to continue the trial so that

defense counsel could endorse his own witness. Counsel refused

this offer. Accordingly, we discern no abuse of discretion in the

court’s ruling denying a Shreck hearing.

VI. Expert Versus Lay Testimony

¶ 52 Mr. Ambrose next contends that Deputy Dilka’s testimony

about the I-9000, specifically that the machine worked properly,

28
 constituted expert testimony in the guise of lay testimony. We

conclude that any error was harmless.

A. Standard of Review and Law

¶ 53 Again, we review a trial court’s evidentiary rulings for an

abuse of discretion. Venalonzo v. People, 2017 CO 9, ¶ 15. A trial

court abuses its discretion when its ruling is unreasonable,

arbitrary, or contrary to law. Id. Preserved errors in the admission

of evidence are reviewed under the harmless error standard. People

v. Stewart, 55 P.3d 107, 124 (Colo. 2002). Such a ruling is not

reversible “unless the ruling affects a substantial right of the party

against whom the ruling is made.” Id. “If a reviewing court can say

with fair assurance that, in light of the entire record of the trial, the

error did not substantially influence the verdict or impair the

fairness of the trial, the error may properly be deemed harmless.”

Id. (citations omitted).

¶ 54 CRE 701 and 702 distinguish lay and expert testimony.

Under CRE 701, a lay opinion must be “(a) rationally based on the

perception of the witness, (b) helpful to a clear understanding of the

witness’[s] testimony or the determination of a fact in issue, and (c)

not based on scientific, technical, or other specialized knowledge

29
 within the scope of [CRE] 702.” Under CRE 702, “[i]f scientific,

technical, or other specialized knowledge will assist the trier of fact

to understand the evidence or to determine a fact in issue, a

witness qualified as an expert by knowledge, skill, experience,

training, or education, may testify thereto in the form of an opinion

or otherwise.”

¶ 55 A witness’s basis for his opinion and the nature of the

experiences that form such opinion distinguish lay testimony from

expert testimony. Venalonzo, ¶ 22; see Stewart, 55 P.3d at 123.

With lay opinion testimony, “courts consider whether ordinary

citizens can be expected to know certain information or to have had

certain experiences.” Venalonzo, ¶ 22 (quoting People v. Rincon,

140 P.3d 976, 982 (Colo. App. 2005)). On the other hand, expert

testimony requires experience or skills that go beyond common

experience. Id. Therefore, a trial court must look to the basis for

the witness’s opinion in order to determine whether it amounts to

lay or expert testimony. Id. at ¶ 23.

B. Application

¶ 56 Deputy Dilka testified about the step-by-step procedures he

followed when operating the I-9000 machine, including testing air

30
 blanks before testing Mr. Ambrose’s breath. He also testified about

the results the machine generated at each step, including “zero”

readings for air blanks and a 0.063 reading for Mr. Ambrose’s

sample. After Deputy Dilka had described the process and results

generated, the prosecutor asked him whether it appeared to him

that the I-9000 machine used here “was working properly.” He

responded, “It does.” The prosecutor then admitted the machine-

generated report describing the data generated. See Stewart, 55

P.3d at 123 (a police officer’s testimony about his experiences and

perceptions is lay opinion testimony).

¶ 57 We acknowledge that Deputy Dilka’s opinion is arguably an

expert opinion because it was based on specialized training that he

received in the operation of the I-9000. See Venalonzo, ¶ 23 (if “the

witness provides testimony that could not be offered without

specialized experiences, knowledge, or training, then the witness is

offering expert testimony”); People v. Veren, 140 P.3d 131, 136

(Colo. App. 2005) (“[W]hen an officer’s opinions require the

application of, or reliance on, specialized skills or training, the

officer must be qualified as an expert before offering such

31
 testimony.” (quoting Stewart, 55 P.3d at 123)). The prosecutor did

not qualify Deputy Dilka as an expert, however.

¶ 58 Nevertheless, we conclude that any error was harmless

because Deputy Dilka’s testimony did not substantially influence

the verdict or the fairness of the trial. First, the prosecution

presented substantial evidence of Mr. Ambrose’s impairment. See

Campbell v. People, 2019 CO 66, ¶¶ 41-42 (improperly admitting an

officer’s expert testimony about the horizontal gaze nystagmus test

was harmless because other evidence, including the defendant’s

performance on other field sobriety tests, overwhelmingly supported

the jury’s conclusion that the defendant’s ability to drive was

impaired by alcohol). Deputy Dilka described Mr. Ambrose’s glassy

eyes, an odor of alcohol on Mr. Ambrose’s person, and Mr.

Ambrose’s failure of several roadside sobriety tests, all of which are

indicative of impairment.

¶ 59 As well, Deputy Dilka never interpreted the I-9000’s results

and never opined that the I-9000 indicated Mr. Ambrose was

impaired. Unlike Veren, where the division found that the

improperly admitted opinion constituted the only evidence of

distribution used to convict the defendant of distribution of a

32
 controlled substance, 140 P.3d at 140, the jury here had

substantial other evidence, beyond the breath test, from which to

determine that Mr. Ambrose was impaired to the slightest degree.

Accordingly, we discern no reversible error in the admission of

Deputy Dilka’s opinion.

VII. I-9000 Certificate

¶ 60 Mr. Ambrose next contends that the I-9000 certificate and

results are inadmissible as a matter of law because the certificate,

printed by the machine at the time of the test, lacks a signature.

So, he says, the trial court abused its discretion by admitting it. We

disagree.

¶ 61 As noted above, we review a trial court’s evidentiary rulings for

an abuse of discretion. Nicholls v. People, 2017 CO 71, ¶ 17.

¶ 62 Section 42-4-1303, C.R.S. 2020, provides as follows:

Official records of the department of public
health and environment relating to
certification of breath test instruments,
certification of operators and operator
instructors of breath test instruments,
certification of standard solutions, and
certification of laboratories shall be official
records of the state, and copies thereof,
attested by the executive director of the
department of public health and environment or
the director’s deputy and accompanied by a

33
 certificate bearing the official seal for said
department that the executive director or the
director’s deputy has custody of said
records, shall be admissible in all courts of
record and shall constitute prima facie proof of
the information contained therein. The
department seal required under this
section may also consist of a rubber stamp
producing a facsimile of the seal stamped upon
the document.

(Emphasis added.) Our supreme court has held that “any

deficiency in the evidence with respect to the state board of health

certifications should be considered as to the weight to be given the

test results and not as to their admissibility.” Thomas v. People,

895 P.2d 1040, 1046 (Colo. 1995).

¶ 63 The parties do not dispute that the I-9000 certificate was not

signed by the executive director of CDPHE, or that it included the

department’s seal. Even assuming without deciding that the

statute requires a signature, we apply our supreme court’s rule that

any such deficiency goes to the weight of the evidence and not its

admissibility. See id. Therefore, we discern no error by the trial

court in admitting the certificate, and we need not address the

People’s or Mr. Ambrose’s statutory arguments.

34
 VIII. Confrontation

¶ 64 Mr. Ambrose next contends that, if the I-9000 certificate is

admissible under section 42-4-1303, then it is testimonial, and the

statute violates his Sixth Amendment right to confrontation both

facially and as applied. Specifically, he argues that if section

42-4-1303 allows the prosecutor to avoid calling the state analyst

who certified the machine, without proving that the analyst was

unavailable, the statute violates his right to confront witnesses. We

are not persuaded.

A. Standard of Review

¶ 65 As previously stated, we review a court’s evidentiary rulings for

an abuse of discretion. Nicholls, ¶ 17. But possible violations of

the Confrontation Clause are reviewed de novo. Bernal v. People, 44

P.3d 184, 198 (Colo. 2002). Statutory interpretation is also

reviewed de novo. McCoy v. People, 2019 CO 44, ¶ 37.

¶ 66 We review preserved evidentiary errors under the harmless

error standard and confrontation violations under the constitutional

harmless error standard. Hagos v. People, 2012 CO 63, ¶¶ 11-12.

However, we review unpreserved errors — constitutional and

nonconstitutional — for plain error. Id. at ¶ 14; People v. Barry,

35
 2015 COA 4, ¶ 65. “[U]nder plain error analysis, [the] defendant

must establish that error occurred, that the error was obvious, and

that the error’s effect is so grave that it undermines the

fundamental fairness of the trial itself and casts doubt upon the

reliability of the conviction.” Barry, ¶ 71.

B. Preservation

¶ 67 As a threshold matter, the parties dispute preservation of this

issue. Mr. Ambrose argues that he preserved the issue in his

motion for a Shreck hearing by asserting that

[t]o the extent that the People argue Colo. Rev.
Stat. §42-4-1303 permits admission of the
I-9000 results, this argument fails to take into
consideration the constitutional implications of
admitting untested, unreliable, and potentially
misleading evidence in violation of Rule 702,
403, and state and federal constitutional
guarantees of Due Process and Confrontation.

(Emphasis added.)

¶ 68 Mr. Ambrose also relies on counsel’s objection during trial to

admission of the I-9000 certificate and the breath test results “as

unreliable.” The People argue that this was insufficient to preserve

Mr. Ambrose’s appellate argument that admission of the working

order certificate violated his rights under the Confrontation Clause.

36
 The trial court did not rule on the confrontation issue when it

denied defense counsel’s motion for a Shreck hearing.

¶ 69 We acknowledge that a pretrial motion, like the one here, may

preserve an evidentiary objection for appellate review “if the moving

party fairly presents the issue to the court and the court issues a

definitive ruling.” People v. Dinapoli, 2015 COA 9, ¶ 20; see also

People v. Gross, 39 P.3d 1279, 1281 (Colo. App. 2001) (“[W]here a

party objects during a pretrial hearing on a motion in limine . . . the

objector is entitled to assume that the trial court will adhere to its

initial ruling and that the objection need not be repeated.”). But a

defendant may forfeit his right to fix a constitutional error by failing

to make an adequate objection during trial. Martinez v. People,

2015 CO 16, ¶ 13. General objections are insufficient. Id. at ¶ 14.

Although no “talismanic language” is required to preserve an

argument for appeal, a party “must present the trial court with ‘an

adequate opportunity to make findings of fact and conclusions of

law’ on the issue.” Id. (citation omitted); see also Phillips v. People,

2019 CO 72, ¶ 12 (to preserve a claim for appellate review, the party

asserting error must have supplied the right ground for the request

37
 and that conclusory boilerplate contentions constitute insufficient

preservation).

¶ 70 Counsel’s pretrial motion objected only to the I-9000’s results

and not to the certificate related to the machine’s proper working

condition. As well, counsel objected to the admission of the I-9000

certificate and the breath test results during trial, but only “as

unreliable,” without mentioning or arguing the Confrontation

Clause. We conclude that the motion and this objection were

insufficient to provide the trial court with a meaningful opportunity

to determine whether the I-9000 certificate was testimonial and

subject to the Confrontation Clause or whether section 42-4-1303

was unconstitutional, either facially or as applied. Therefore, we

conclude that Mr. Ambrose did not preserve the Confrontation

Clause issue as framed in the opening brief, and we review for plain

error.

C. Applicable Law

¶ 71 “The Sixth Amendment of the United States Constitution

affords to the accused the right ‘to be confronted with the witnesses

against him.’” Marshall v. People, 2013 CO 51, ¶ 15 (quoting U.S.

Const. amend. VI); see Colo. Const. art. II, § 16 (“In criminal

38
 prosecutions the accused shall have the right . . . to meet the

witnesses against him face to face . . . .”). When evaluating a

potential Confrontation Clause violation, we must first determine

whether the statement at issue was testimonial. See Crawford v.

Washington, 541 U.S. 36, 68-69 (2004). Admission of a testimonial

hearsay statement against the defendant violates the Confrontation

Clause unless the declarant is unavailable and the defendant had

an opportunity to cross-examine the declarant. Id.

¶ 72 “[A]t a minimum, statements are testimonial if the declarant

made them at a ‘preliminary hearing, before a grand jury, or at a

former trial; and [in] police interrogations.’” People v. Vigil, 127 P.3d

916, 921 (Colo. 2006) (citation omitted). Three formulations of

statements qualify as testimonial in nature: (1) “ex parte in-court

testimony or its functional equivalent,” such as “affidavits, custodial

examinations, prior testimony that the defendant was unable to

cross-examine, or similar pretrial statements that declarants would

reasonably expect to be used prosecutorially”; (2) “extrajudicial

statements . . . contained in formalized testimonial materials, such

as affidavits, depositions, prior testimony or confessions”; and (3)

“statements that were made under circumstances which would lead

39
 an objective witness reasonably to believe that the statement would

be available for use at a later trial.” Id. (quoting Crawford, 541 U.S.

at 51-52).

¶ 73 In Melendez-Diaz v. Massachusetts, 557 U.S. 305 (2009), the

United States Supreme Court held that laboratory certificates

reporting the results of forensic analyses performed on substances

are functionally equivalent to affidavits. The Court determined that

the affidavits are “testimonial,” and therefore implicate a

defendant’s Sixth Amendment right to confront witnesses against

him, because they are made for the purpose of establishing some

material fact at the defendant’s trial and under circumstances that

would lead a reasonably objective witness to believe that the

statements contained therein would be available for use at a later

trial. Id. at 310-11.

¶ 74 Even before Melendez-Diaz, our supreme court held that

laboratory reports are testimonial and subject to the Confrontation

Clause. Hinojos-Mendoza v. People, 169 P.3d 662, 666 (Colo. 2007),

abrogated on other grounds by Phillips, ¶¶ 32-33. The court rejected

the rationale that a lab report qualifies as a business record and

that the practice of weighing an undisputed substance “merely . . .

40
 authenticated the document.” Id. (citation omitted). Instead, the

court held that the lab report was testimonial for two reasons.

First, the “report was prepared at the direction of the police and a

copy of the report was transmitted to the district attorney’s office”;

thus, the court reasoned, there could be no serious dispute that the

report’s sole purpose was to analyze the substance found in

anticipation of a criminal prosecution. Id. at 667. Second, the

report admitted at trial established an element of the offense with

which the defendant was charged. Id. The court reaffirmed this

position a few years later. See Marshall, ¶ 15 (“The People appear to

concede, and we agree, that the [lab] report in this case was

testimonial in nature.” (first citing Bullcoming v. New Mexico, 564

U.S. 647, 664-65 (2011); then citing Hinojos-Mendoza, 169 P.3d at

667)).

¶ 75 However, neither our supreme court nor the United States

Supreme Court has decided whether a certificate used to establish

that an intoxilyzer machine complies with state rules and

regulations is testimonial and subject to the Confrontation Clause.

But all of the state courts that have considered this issue have

concluded that such certificates are not testimonial and do not

41
 implicate the Confrontation Clause. We hold that the I-9000

certificate here is not testimonial and reject Mr. Ambrose’s facial

and as-applied challenges to section 42-4-1303.

D. Analysis

¶ 76 The I-9000 certificate differs from the document at issue in

Melendez-Diaz in three ways. First, the document in Melendez-Diaz

contained forensic analysis results used to prove the identity of the

illicit substance (an element of the crime) and was sworn before a

notary public by the reporting analyst. See 557 U.S. at 308-09. In

contrast, the I-9000 certificate contains no testing results, but

simply certifies that the I-9000 machine complies with CDPHE-

approved methods (not an element of a crime) to measure a

person’s BAC. See Commonwealth v. Zeininger, 947 N.E.2d 1060,

1069 (Mass. 2011) (distinguishing certificates of drug analysis

offered as direct proof of an element of the offense charged from

Office of Alcohol Testing certification records, which “bear only on

the admissibility or credibility of the evidence”); People v. Pealer,

985 N.E.2d 903, 907 (N.Y. 2013) (affirming breathalyzer testing

certificates are not testimonial in part because they “do not directly

inculpate defendant or prove an essential element of the charges

42
 against him”). Moreover, the I-9000 certificate did not include a

sworn statement.

¶ 77 Second, unlike the document in Melendez-Diaz, the I-9000

certificate is not prepared in anticipation of a particular

prosecution. See State v. Bergin, 217 P.3d 1087, 1089 (Or. Ct. App.

2009) (“[T]he person who performs the test of a machine’s accuracy

does so with no particular prosecutorial use in mind, and, indeed,

there is no guarantee that the machine will ever, in fact, be used.”).

Instead, the certificate — which the I-9000 prints

contemporaneously with the breath test result — contains only the

machine’s serial number, the date range of the certificate’s validity,

and CDPHE’s seal, consistent with the statutory and regulatory

requirements. See § 42-4-1304(4), C.R.S. 2020 (requiring the state

board of health to promulgate rules and procedures for the

collection and testing of blood and breath samples for alcohol and

drugs). The fact that the certificate is printed contemporaneously

with the test result does not mean that it is prepared for a specific

prosecution. See Zeininger, 947 N.E.2d at 1065 (explaining that the

notation of certification at issue appeared “on the same report as

the results of the breathalyzer test”).

43
¶ 78 Finally, rather than proving the material fact of a person’s

BAC, the I-9000 certificate proves only that the device used to

measure a person’s BAC complies with state regulations. Dep’t of

Pub. Health & Env’t Reg. 4.1.3.2, 5 Code Colo. Regs. 1005-2

(requiring that CDPHE “certify each Evidential Breath Alcohol Test

instrument initially and annually thereafter”); Dep’t of Pub. Health

& Env’t Reg. 4.1.3.3, 5 Code Colo. Regs. 1005-2 (providing that

CDPHE will issue a certificate for each instrument after initial

certification and after each annual certification, with each

certificate reflecting the instrument serial number and the dates of

the certification period). Indeed, the I-9000 certificate in this case

did not mention Mr. Ambrose or his BAC result. See also

Commonwealth v. Dyarman, 73 A.3d 565, 569 (Pa. 2013)

(distinguishing calibration and accuracy certificates for breath test

machines from the certificates in Melendez-Diaz because “the

certificates at issue here did not provide any information regarding

appellant’s BAC or even refer to her”).

¶ 79 We are not persuaded that the certificate, which showed the

I-9000 was working properly, was testimonial simply because the

breath test result, contained in a separate document, permitted the

44
 jury to infer that Mr. Ambrose was impaired. See § 42-4-

1301(6)(a)(II); see also People v. Hamilton, 2019 COA 101, ¶¶ 24-26

(time stamps and similar information that a machine generates

without human intervention are not “statements” and, thus, are not

hearsay); Cranston v. State, 936 N.E.2d 342, 345 (Ind. Ct. App.

2010) (an evidence ticket produced by a chemical breath machine is

not testimonial hearsay for purposes of the Sixth Amendment). The

I-9000 certificate merely constitutes prima facie evidence that the I-

9000 used to test Mr. Ambrose’s breath complied with CDPHE

regulations. See People v. Ortega, 2016 COA 148, ¶ 11 (attestation

used merely to authenticate phone records was not testimonial and

thus not subject to the Confrontation Clause).

¶ 80 And we agree with the decisions of other state courts that have

found similar certificates nontestimonial because they “bear a more

attenuated relationship to conviction.” Bergin, 217 P.3d at 1089;

see also State v. Kramer, 278 P.3d 431, 437 (Idaho Ct. App. 2012)

(Intoxilyzer 5000 certificates “were not direct proof of an element of

the crime of driving under the influence,” but were “instead

admitted as proof that the testing instrument was working

properly”); Dyarman, 73 A.3d at 570 (calibration and accuracy

45
 certificates do not establish an element of an offense, but instead

concern “the weight to be accorded to the test results”).

¶ 81 Further, our conclusion is consistent with dictum in Melendez-

Diaz:

Contrary to the dissent’s suggestion, we do not
hold, and it is not the case, that anyone whose
testimony may be relevant in establishing the
chain of custody, authenticity of the sample, or
accuracy of the testing device, must appear in
person as part of the prosecution’s case. . . .
Additionally, documents prepared in the regular
course of equipment maintenance may well
qualify as nontestimonial records.

557 U.S. at 311 n.1 (emphasis added) (citation omitted).

¶ 82 Indeed, Mr. Ambrose has not cited, nor have we found, any

case from any jurisdiction holding that certificates similar to the

I-9000 working order certificate are testimonial and subject to the

Confrontation Clause. See Smith v. State, 791 S.E.2d 418, 422 (Ga.

Ct. App. 2016) (“inspection certificates are not testimonial in

nature”); Jones v. State, 982 N.E.2d 417, 428 (Ind. Ct. App. 2013)

(reaffirming prior precedents and concluding such certificates are

“nontestimonial”); State v. Benson, 287 P.3d 927, 932 (Kan. 2012)

(holding “that [a] certificate of calibration is not a testimonial

statement”); State v. Britt, 813 N.W.2d 434, 437 (Neb. 2012)

46
 (affirming that certificate by analyst who prepared breath test

simulator solution used to test the device was not testimonial and

therefore not subject to confrontation analysis); State v. Dial, 998

N.E.2d 821, 827 (Ohio Ct. App. 2013) (a certificate of a breath test

machine using a new bottle of ethyl alcohol was not testimonial);

Anderson v. State, 317 P.3d 1108, 1122 (Wyo. 2014) (annual

certification of breathalyzer machines is not testimonial for

purposes of the Confrontation Clause).

¶ 83 We are also not persuaded that Barry requires a different

result, for three reasons. In Barry, ¶ 67, the emergency medical

technician (EMT) who drew the defendant’s blood for a blood alcohol

test signed a certificate stating that she drew the blood by

venipuncture and that she was an EMT. Colorado law authorizes

EMTs to draw a person’s blood for criminal investigations in

accordance with Colorado State Board of Health rules and

regulations, and these rules require that the EMT collect the blood

using venipuncture. Id. at ¶ 76. The EMT did not testify at trial,

and a division of this court concluded that the EMT’s certificate

constituted a hearsay testimonial statement. Id. at ¶ 79.

47
¶ 84 First, unlike the EMT in Barry, Deputy Dilka, the person who

collected the sample and tested it, testified at trial and was

available for cross-examination both as to his procedures and as to

the functioning of the equipment he used. Second, and in contrast

to Barry, the I-9000 certificate validated the machine’s proper

functioning for a range of dates — not just for the prosecution of

Mr. Ambrose’s case. See id. at ¶ 67 (EMT’s certificate was prepared

specifically for the prosecution of the defendant); see also Ramirez

v. State, 928 N.E.2d 214, 219-20 (Ind. Ct. App. 2010) (a certificate

of inspection and compliance for a machine used in a chemical

breath test was “not prepared for a particular prosecution of any

one defendant”); Bergin, 217 P.3d at 1089. As well, the EMT’s

certificate was not merely a document “prepared in the regular

course of equipment maintenance.” Melendez-Diaz, 557 U.S. at 311

n.1.

¶ 85 And third, the I-9000 certificate is an official record that

CDPHE is statutorily required to maintain. Section 42-4-1304(4)(a)

empowers and requires CDPHE to establish rules and procedures

for certifying the collection and testing of blood and breath samples

for alcohol and drugs, and those rules require that CDPHE annually

48
 certify instruments like the I-9000. Dep’t of Pub. Health & Env’t

Reg. 4.1.3.2, 5 Code Colo. Regs. 1005-2. There are no similar

statutory or regulatory requirements for an EMT to certify how he or

she drew blood.

¶ 86 We are also not persuaded that Bullcoming requires a different

result. In Bullcoming, an analyst who did not perform the

defendant’s blood alcohol test testified about the results another

analyst had obtained. 564 U.S. at 659-60. The United States

Supreme Court held that such testimony violated the defendant’s

confrontation right. Id. at 657-58. We find Bullcoming

distinguishable for two reasons. First, as explained above, the

I-9000 certificate is not testimonial. It does not prove a defendant’s

BAC or any other material fact, but, instead, establishes that the

machine operates properly and complies with regulatory

requirements. Second, the individual responsible for using the

device and taking measurements, Deputy Dilka, testified at trial

and, therefore, was available for cross-examination.

¶ 87 Finally, even if we were to find that an error occurred, we

conclude that it would not constitute plain error given the plethora

of case law from other jurisdictions finding similar certificates not

49
 testimonial. See People v. Pollard, 2013 COA 31M, ¶ 41 (the

uniformity with which numerous other courts have embraced a rule

even in the absence of Colorado case law squarely on point is

relevant to plain error analysis).

¶ 88 Accordingly, we hold that the I-9000 certificate is not

testimonial and that its admission did not implicate Mr. Ambrose’s

right to confront witnesses. We also conclude that section 42-4-

1303 does not, facially or as applied, violate the Confrontation

Clause.

IX. Conclusion

¶ 89 The felony DWAI conviction is reversed, and the case is

remanded for imposition of a misdemeanor DWAI and resentencing,

unless the prosecution opts to retry the felony DWAI charge. The

judgment is affirmed in all other respects.

JUDGE TERRY and JUDGE LIPINSKY concur.
