RE: State v. Clark, I.D. No. 2509003414
Counsel:
Mr. Clark moves to compel the State to produce slides and other material used
by the Delaware State Police Crime Lab (hereinafter, “Crime Lab”) to train police
officers to operate the Intoxilizyer 9000 (hereinafter, “the 9000”). The 9000 is an
updated and improved alcohol breath testing device used by police agencies around
the State in driving under the influence investigations.
Mr. Clark, charged with a felony DUI, contends that he belched during the
twenty-minute observation period prior to his test. As a result, he contends that any
written material or training guidelines in the State’s possession addressing the 9000’s
operator instructions are material to the preparation of his defense.
The State opposes producing the material. At the outset, it contends that the
9000’s manufacturer, CMI, Inc. (“CMI”), provided no operator or user manual for
the device. Rather, the Crime Lab has prepared the only documents explaining these
procedures. It has done so for the purpose of training the device’s officer-operators.
Accordingly, the training slides are the only written documents in the State’s
possession that provide operating procedures for the 9000.
The State’s primary reason for resisting production is that it contends the
materials are exempt from disclosure because of copyright protection due CMI.1 It
relies on Superior Court Criminal Rule 16(b)(2)(A)’s exception to criminal
discovery when doing so.
The Court has reviewed the materials in camera to resolve the dispute. For
the reasons to follow, these slides, which are the only existing written explanation of
operator and usage procedures for the 9000, are material to the preparation of Mr.
Clark’s defense. Furthermore, they do not fit within the exception to criminal
discovery that the State relies upon. Accordingly, Mr. Clark’s motion to compel is
granted.
BACKGROUND
The State charges Mr. Clark with a third offense DUI. CMI manufactured the
9000 and a Dover police officer used the machine to test Mr. Clark’s blood alcohol
level after his arrest. Mr. Clark contends that he burped or belched within the twenty-
minutes preceding his test. Thus, he argues that the operating guidelines contained
in the slides are material to his defense because he believes they recognize a
mandatory pre-test observation period.
The question regarding whether the long-recognized twenty-minute
observation period is (1) foundational for a 9000 result (given the 9000’s internal
screenings for excess mouth alcohol), or (2) simply goes to the weight of the
1
At first, the State mistakenly contended that CMI created the training slides and materials. It
later corrected that mistake by clarifying that the Crime Lab created them. It maintains, however,
that the Crime Lab created them with the use of some information obtained from CMI.

evidence has not been addressed for the 9000 as it has been for the 5000.2 Today,
the Court need not resolve whether a burp, belch, or regurgitation during the
observation period is foundational or goes to the weight of the evidence due. It need
not because the training documents are material to the preparation of Mr. Clark’s
defense either way.
Mr. Clark’s initial criminal discovery request sought, inter alia, copies of (1)
CMI’s user or operator manuals for the 9000, and (2) the Delaware State Police and
Dover Police Department user or operator manuals for the device. At oral argument
on the motion, the State represented that no CMI-provided operator or maintenance
manuals existed. The Court acknowledged the State’s good-faith response but
expressed skepticism that the manufacturer of a scientific device such as this would
market it nationally without providing written standard operating procedures for
end-users. As a result, the Court deferred decision on the motion to compel and
instructed the State to make further efforts to verify what materials were available.
The State then supplemented its response in a letter to Mr. Clark and copied
the Court.3 In that response, the State confirmed that CMI created no operator’s
manual for the device.4 According to a letter attached to the State’s response from
CMI’s President, CMI has not because “[n]umerous law enforcement agencies have
elected to create their own agency-specific operator manuals.”5 The State also
included an affidavit from the Crime Lab’s Director in its response.6 She attested
that the Crime Lab also declined to create an operator or user’s manual for the 9000.7

“must lay an adequate evidentiary foundation showing that there was an uninterrupted twenty-
minute observation of the defendant prior to testing [by the Intoxilyzer 5000]”).

At that point, the State represented mistakenly that CMI had created the training
slides and provided them to the Crime Lab. Finally, in the same letter, the State
refused to produce the slides in discovery but gave no reason as to why.8
Mr. Clark then renewed his motion and asked the Court to perform an in
camera review of the materials that the State had identified but refused to produce.9
Mr. Clark reiterated that the documents were material to preparing his defense in
light of a video that confirms that he belched during the twenty-minute observation
period.
The Court then ordered the State (1) to produce the slides for an in camera
review, and (2) to explain why it believed the documents were privileged by letter
response to the Court.10 In response, the State provided a series of slides for Court
review. In its cover letter, it relied upon Superior Court Criminal Rule 16(b)(2)(A)’s
exception to criminal discovery when opposing production.11 In total, the State
contended that the documents were privileged under copyright law because (1) the
State did not create them, (2) they are “internal operator training” materials for the
9000, and (3) CMI’s copyrights make them privileged.12
Several days later, the State filed an amended response supplementing its prior
disclosures. There, the State explained that the Crime Lab—not CMI—authored the
documents.13 The State nevertheless maintained its position that because CMI
provided some of the information that the Crime Lab included in its slides, only one
unredacted reference to the twenty-minute observation period should be disclosed to

the defense. Again, other than relying on CMI copyright protection as a justification,
the State provided no further explanation regarding why.14
STANDARDS
Criminal discovery has been described as broad,15 but is more restrictive than
civil discovery. Superior Court Criminal Rule 16 provides the categories of
documents that the State must produce. Relevant to this case, the Rule requires
disclosure of the following:
papers, documents . . . or copies or portions thereof, that are within the
possession, custody or control of the state and that are material to the
preparation of the defendant’s defense.16
The defendant bears the initial burden of demonstrating that materials sought under
the Rule are discoverable.17
Rule 16 continues by exempting work-product and other privileged materials
from disclosure. Namely, the following are not subject to disclosure under Rule
16(b)(2)(A):
reports, memoranda, or other internal state documents prepared by the
state or its agents in connection with the investigation or prosecution of
the case that may reasonably be considered confidential, privileged, or
subject to the attorney work-product doctrine.
It is the State that bears the burden of demonstrating that this exception shields
material from production under Rule 16.18

ANALYSIS
The Court reviewed the slides presented in camera. It first evaluated them to
determine whether they fell within a category of discoverable documents under Rule
16. Then, it considered whether the documents were separately shielded from
protection by the work-product doctrine or other privilege.
As to the first question, Rule 16(b)(1)(E) makes documents subject to
disclosure if they are (1) within the custody or control of the State, and (2) material
to the preparation of the accused’s defense. Here, the answer to both questions is
yes for the following reasons.
As to custody or control, the State incorrectly focused at first on the mistaken
belief that CMI had created the documents, which the State seemed to contend, in
turn, divested the Crime Lab of control over them. The State then revised its position
to clarify that the Crime Lab created the documents. Whether or not CMI created
the documents misses the mark in either event. Rather, the central question is
whether the State or its agent currently possesses or controls the documents. Clearly,
the Crime Lab, which is associated with a state law enforcement agency, now
possesses and controls the slides.
Turning to the question of materiality, the inquiry begins by recognizing that
the 9000 is a scientific device that provides per se evidence of impairment. The
materials reference the twenty-minute observation period in multiple locations.
They also include written statements that confirm that the Crime Lab uses the slides
to train officer-operators on the device. Moreover, they include references to other
operational requirements for administering the tests. They also include a sample
certification card that the Crime Lab issues to officers who complete the training.
Upon review, the documents are material to the preparation of Mr. Clark’s
defense in two ways. First, State policy makes the twenty-minute observation
period relevant, and the documents reference that observation period. Moreover,
6
those references make all of the slides material because preparing a defense based
upon a mandatory observation period should be considered in the wider context of
the 9000’s operational guidelines.19 Second, they are material to the preparation of
a defense for a broader reason. That is, an accused has the right to confirm and
challenge whether the administering officer operated the machinery correctly for the
purpose of contesting the result’s reliability. Due process requires no less. A
defendant, such as Mr. Clark, would be left unable to confirm whether an officer
performed the test to standard without reviewing the standards.
On balance, apparently, the only written operating guidelines relevant to
Delaware’s use of the 9000 are the slides and documents that the State produced for
in camera review. Mr. Clark deserves the opportunity to review those documents to
prepare for cross-examination of the administering officer and to test the State’s
position that the officer properly operated the machine. For these reasons, the
entirety of the documents produced in camera are discoverable under Rule
16(b)(1)(E).
The final inquiry settles on whether the State can shield these documents from
disclosure. The State contends that an unspecified portion of the information in the
slides come from CMI-copyrighted material that must be protected under Rule
16(b)(2)(A). For the following three reasons, the State’s justification does not
qualify for the exception.
19
See State v. Brown, 352 A.3d 328, 351 & n.175 (Del. Super. 2025) (observing, after a thorough
evidentiary hearing, that the 9000 requires a twenty-minute pre-test observation period and reciting
the State Chemist’s testimony in a pretrial hearing acknowledging the same). The 9000 may very
well internally compensate for such deficiencies by confirming the validity of the sample.
Nevertheless, that does not change the fact that the training materials provide for a twenty-minute
observation period and other operational requirements that an operator must follow when
administering the test. The documents are material to the defense against a driving under the
influence charge prosecuted with a 9000 result.
7
First, the exception applies to work-product and work-product is not
implicated by operator training materials. The operative phrase in the exception
clarifies that it applies only to “documents prepared by the state or its agents in
connection with the investigation or prosecution of a case.”20 Here, the Crime Lab
used the materials to train the Dover officer well in advance of the investigation and
prosecution of Mr. Clark. Accordingly, this threshold deficiency is singularly
dispositive.
Second, a third-party’s alleged rights could not fall within this exception.
Simply put, there is a standing issue when the State relies on CMI’s rights to shield
documents that are so clearly material to the preparation of Mr. Clark’s defense.21
For this additional reason, any unspecified and alleged copyright protection due CMI
does not justify the State’s refusal to produce otherwise discoverable materials.
Third and finally, even if a third-party’s copyrights could impact the State’s
obligation to produce the documents, the State fails to justify what information
contained in the Crime Lab’s slides and training materials would violate CMI’s
rights. In fact, the cover page of the slides recites only that “this material is used
for training purposes by the DSP Crime Lab and may contain information under
copyright by CMI Inc.” Furthermore, the letter submitted by CMI’s President
supports no copyright infringement because he identifies State and local purchasers
as the ones who establish operational guidelines for the machine.22 Lastly, the
argument misinterprets copyright protection at a basic level. At most, the slides are
a compilation of State-agency and manufacturer operational practices. While
compilations may enjoy copyright protections, the underlying facts in a compilation

21
The State neither identified nor alleged any harm that could befall it by disclosing this
information.

do not.23 The do’s and don’ts in the proper operation of a scientific device used to
prosecute a crime are underlying facts that enjoy no such protection. While the
training slides at issue may contain some information from some other unspecified
documents created by CMI—which contradictorily, the State maintains do not even
exist—such information would be due no copyright protection once the State chose
to include it in its training material.24
In summary, the State failed to demonstrate that a privilege justifies
withholding these documents. Furthermore, the State cites no Delaware or federal
statute, rule, or case authority that would shield these documents because of CMI’s
rights. Finally, a protective order restricting dissemination of these materials is
inappropriate because the State provides no justification for one.25
CONCLUSION
For the reasons above, Mr. Clark’s motion to compel is GRANTED. The
State must produce the complete package of materials reviewed by the Court to Mr.
Clark within seven (7) days of the date of this Order.
IT IS SO ORDERED.

The State also identifies no basis for designating these documents as restricted designation

the Rule.
