Megan A. Ring, Colorado State Public Defender, Rachel Z. Geiman, Deputy State Public Defender, Denver, Colorado, for Defendant-Appellant
*Sitting by assignment of the Chief Justice under provisions of Colo. Const. art. VI, § 5(3), and § 24-51-1105, C.R.S. 2024. ¶1 Defendant, Paul Warren, appeals his conviction for aggravated
motor vehicle theft. We affirm.
I. Background
¶2 L.E.M. hired Warren to help install satellite equipment
throughout the state and loaned him his truck with the
understanding that the truck would be used for work purposes and
returned daily.
¶3 A couple of months later, Warren failed to return the truck.
L.E.M. learned Warren was using the truck to travel to Alabama for
a family matter and reported the truck stolen.
¶4 Warren was charged with aggravated motor vehicle theft and
theft of the tools stored in the truck. A jury convicted him of
aggravated motor vehicle theft.
II. Discussion
¶5 Warren raises two arguments on appeal. First, he contends
the district court erred by giving the 2022 Colorado Model Criminal
Jury Instruction on reasonable doubt. Second, he asserts the court
erred by denying his motion for dismissal for discovery violations by
the prosecution. We affirm.
1 A. Reasonable Doubt Jury Instruction
¶6 Warren argues the court’s reasonable doubt jury instruction
lowered the prosecution’s burden of proof, infringed on his
presumption of innocence, and shifted the burden of proof to him.
We disagree.
1. Additional Background
¶7 In 2022, the Colorado Supreme Court Model Criminal Jury
Instructions Committee substantially revised the reasonable doubt
instruction to read in part:
Proof beyond a reasonable doubt is proof that leaves you firmly convinced of the defendant’s guilt. If you are firmly convinced of the defendant’s guilt, then the prosecution has proven the crime charged beyond a reasonable doubt. But if you think there is a real possibility that the defendant is not guilty, then the prosecution has failed to prove the crime charged beyond a reasonable doubt.
After considering all the evidence, if you decide the prosecution has proven each of the elements of a crime charged beyond a reasonable doubt, you should find the defendant guilty of that crime.
After considering all the evidence, if you decide the prosecution has failed to prove any one or more of the elements of a crime charged beyond a reasonable doubt, you should find the defendant not guilty of that crime. 2 COLJI-Crim. E:03 (2022).
¶8 Guided by the 2022 model jury instruction, the district court
gave the following reasonable doubt instruction:
Proof beyond a reasonable doubt is proof that leaves you firmly convinced of the defendant’s guilt. If you are firmly convinced of the defendant’s guilt, then the prosecution has proven the crime charged beyond a reasonable doubt. But if you think there is a real possibility that the defendant is not guilty, then the prosecution has failed to prove the crime charged beyond a reasonable doubt.
If you find from the evidence that each and every element of a crime has been proven beyond a reasonable doubt, you should find the defendant guilty of that crime. If you find from the evidence that the prosecution has failed to prove any one or more of the elements of a crime beyond a reasonable doubt, you should find the defendant not guilty of that crime.
3 ¶9 Warren objected and requested the court use the 2021 model
instruction1 because the 2022 version was untested and lessened
the prosecution’s burden. The district court declined, explaining
that the new instruction repeatedly emphasized that the
prosecution carried the burden of proof.
2. Standard of Review
¶ 10 The United States Constitution “protects the accused against
conviction except upon proof beyond a reasonable doubt of every
fact necessary to constitute the crime with which he is charged.” In
re Winship, 397 U.S. 358, 364 (1970). The reasonable doubt
standard gives “concrete substance” to the presumption of
innocence afforded to all criminal defendants. Id. at 363.
1 The 2021 Colorado Model Criminal Jury Instructions defined
“reasonable doubt” as
a doubt based upon reason and common sense which arises from a fair and rational consideration of all of the evidence, or the lack of evidence, in the case. It is a doubt which is not a vague, speculative or imaginary doubt, but such a doubt as would cause reasonable people to hesitate to act in matters of importance to themselves.
COLJI-Crim. E:03 (2021). 4 ¶ 11 We review de novo whether the district court properly
instructed the jury on the law. Tibbels v. People, 2022 CO 1, ¶ 22.
If an instruction lowers the “prosecution’s burden of proof below the
reasonable doubt standard,” it “constitute[s] structural error and
require[s] automatic reversal.” Id.
¶ 12 In determining whether an instruction lowered the burden of
proof, we apply a “functional test, asking whether there is a
reasonable likelihood that the jury understood a contested
instruction, in the context of the instructions as a whole and the
trial record, to allow a conviction based on a standard lower than
beyond a reasonable doubt.” Id. at ¶ 36; see also People v.
Schlehuber, 2025 COA 50, ¶13.
¶ 13 Model instructions, while not “‘a safe harbor that insulates
instructional error from reversal,’ have been approved in principle
by our [supreme] court and serve as beacon lights to guide trial
courts.” Galvan v. People, 2020 CO 82, ¶ 38 (citations omitted).
Thus, if the instructions as a whole correctly inform the jury of the
law, the district court has “broad discretion to determine the form
5 and style of jury instructions.” Day v. Johnson, 255 P.3d 1064,
1067 (Colo. 2011).
3. Analysis
¶ 14 Warren challenges three aspects of the 2022 model jury
instruction as given by the district court: (1) its failure to instruct
the jury it could consider the “lack of evidence”; (2) its equating of
reasonable doubt with “a real possibility that the defendant is not
guilty” and its use of the phrase “firmly convinced” to define proof
beyond a reasonable doubt; and (3) its removal of the phrase
“hesitate to act” from the 2021 model instruction. None of these
concerns merit reversal.
a. Lack of Evidence
¶ 15 The 2022 model instruction removed the phrase “lack of
evidence,” COLJI-Crim. E:03 (2021), and instructed the jury that in
determining whether the defendant is guilty beyond reasonable

3. Analysis
¶ 14 Warren challenges three aspects of the 2022 model jury
instruction as given by the district court: (1) its failure to instruct
the jury it could consider the “lack of evidence”; (2) its equating of
reasonable doubt with “a real possibility that the defendant is not
guilty” and its use of the phrase “firmly convinced” to define proof
beyond a reasonable doubt; and (3) its removal of the phrase
“hesitate to act” from the 2021 model instruction. None of these
concerns merit reversal.
a. Lack of Evidence
¶ 15 The 2022 model instruction removed the phrase “lack of
evidence,” COLJI-Crim. E:03 (2021), and instructed the jury that in
determining whether the defendant is guilty beyond reasonable
doubt, “all the evidence” should be considered. COLJI-Crim. E:03
(2022). Warren claims this change undercuts the presumption of
innocence by not informing the jurors they can consider both the
6 “lack of evidence” and “all the evidence,” thus lowering and shifting
the prosecution’s burden of proof.2
¶ 16 Courts have recognized, though, that the concept of
reasonable doubt inherently invites jurors to consider missing
evidence. Schlehuber, ¶ 21; see United States v. Rogers, 91 F.3d 53,
56-57 (8th Cir. 1996); see also United States v. Petty, 856 F.3d
1306, 1311 (10th Cir. 2017). Moreover, the lack of evidence on an
issue means the prosecution failed to meet its burden. See
Schlehuber, ¶¶ 21-22; see also Petty, 856 F.3d at 1311 (“Any
reasonable juror would understand from the instruction’s wording
that the Government must present evidence sufficient to establish
Defendant’s guilt beyond a reasonable doubt and that a failure to
present evidence sufficient to meet its burden must result in
Defendant’s acquittal.”).
¶ 17 Divisions of this court have also rejected Warren’s argument.
See Schlehuber, ¶ 19 (“[T]he omission of this phrase from the
2 The reasonable doubt model jury instruction was again amended
in 2023 to state, “A reasonable doubt can be based on the evidence presented or the lack of evidence presented.” COLJI-Crim. E:03 (2023). The addition of this language, however, does not affect our analysis. 7 reasonable doubt instruction is not structural error.”); People v.
Melara, 2025 COA 48, ¶ 24. We conclude that, read as a whole, the
instruction adequately informed the jury of the law. See
Schlehuber, ¶ 22.
¶ 18 In addition, we agree with the Schlehuber division that while it
is better for a district court to instruct the jury explicitly that it may
consider the lack of evidence, a court does not err by not doing so.
Id. at ¶ 20.
b. Firmly Convinced and Real Possibility
¶ 19 Next, Warren argues the instruction erroneously defined
reasonable doubt as a “real possibility that the defendant is not
guilty” and that proof beyond reasonable doubt is proof that leaves
you “firmly convinced.” He contends this language creates
confusion. Addressing both phrases together, we disagree.
¶ 20 These phrases have been consistently approved by courts as
an accurate expression of the reasonable doubt standard. See
Petty, 856 F.3d at 1310 (“[T]he ‘firmly convinced’ language,
juxtaposed with the insistence that a jury must acquit in the
presence of a ‘real possibility’ that the defendant is not guilty, is a
8 correct and comprehensible statement of the reasonable doubt
standard.”) (citation omitted); see Victor v. Nebraska, 511 U.S. 1,
24-25, 27 (1994) (Ginsburg, J., concurring in part and concurring
in the judgment) (endorsing a similar definition as “surpass[ing]
others . . . in stating the reasonable doubt standard succinctly and
comprehensibly”). Divisions of this court have also approved both
phrases as an “accurate statement of the law.” Schlehuber, ¶ 30
(quoting Melara, ¶ 30). We, too, conclude that both phrases
represent an accurate statement of the law.
¶ 21 Warren points us to cases that have disapproved of the
language. See United States v. Porter, 821 F.2d 968, 973 (4th Cir.
1987); United States v. McBride, 786 F.2d 45, 52 (2d Cir. 1986).
But even then, those courts did not deem the language to be a
reversible error, Schlehuber, ¶ 30 n.4, and both cases predate
Justice Ginsburg’s concurrence in Victor v. Nebraska, which
endorsed such an instruction. See Victor, 511 U.S. at 27 (Ginsburg,
J., concurring in part and concurring in the judgment).
¶ 22 As the division in Schlehuber explained, “[t]he first — ‘firmly
convinced’ — describes what it means to have no reasonable
9 doubt,” and “[t]he second — ‘real possibility’ — contrasts that with
what it means to have a reasonable doubt.” Schlehuber, ¶ 33. In
this case, “the jury could either be ‘firmly convinced’ of [Warren’s]
guilt (and find him guilty) or ‘think there is a real possibility’ that
[Warren] was not guilty (and find him not guilty).” Id.
c. Hesitate to Act
¶ 23 Finally, we reject Warren’s contention that the removal of the
“hesitate to act” language risks lowering the burden of proof. While
Warren points to other courts that have previously approved this
language, he fails to state why failing to include it is error. See
Schlehuber, ¶ 28; see also Victor, 511 U.S. at 20.3
¶ 24 The exclusion of the phrase “hesitate to act” in the model
reasonable doubt instruction was, in part, a response to criticisms
that it led some courts to make improper analogies that lowered the
burden of proof. COLJI-Crim. E:03 cmt. 1 (2024); see also
3 The “hesitate to act” analogy is misplaced because decisions
people make in their lives “generally involve a very heavy element of uncertainty and risk-taking” and are “unlike the decisions jurors ought to make in criminal cases.” Victor, 511 U.S. at 24-25 (Ginsburg, J., concurring in part and concurring in the judgment) (citation omitted). 10 Schlehuber, ¶ 27. We agree with the Schlehuber division; “so long
as the instruction otherwise correctly defines the reasonable doubt
standard,” we do not find that the absence of the “hesitate to act”
phrase constitutes error. Schlehuber, ¶ 28.
¶ 25 We hold the reasonable doubt instruction neither lowered nor
shifted the burden of proof, nor did it undermine Warren’s
presumption of innocence. Although we conclude the jury
instruction was sufficient, we do not opine about whether the 2021
Colorado Model Criminal Jury Instruction or the 2022 version
provides the better description of the burden of proof.
B. Discovery Violations
¶ 26 Warren also contends the district court abused its discretion
by denying his motion to dismiss based on the prosecution’s
repeated discovery violations. We discern no abuse of discretion.
¶ 27 Throughout the course of the case, Warren raised multiple
Crim. P. 16 issues:
• January 27, 2023: Warren raised a potential Rule 16
violation based on the prosecution’s late disclosure —
11 just one day earlier — of an interview conducted with
Mitchell. The district court found no violation.
• January 31, 2023: Warren moved to dismiss for Rule 16
violations, reiterating previous concerns and asserting
the prosecution had delayed disclosing fifteen pages of
text messages between Warren and Mitchell. The
prosecution conceded the discovery violation. The
district court agreed a Rule 16 violation had occurred but
concluded it was not willful. As a remedy, the district
court reset trial within the existing speedy trial deadline.
• February 8, 2023: Warren filed a second motion to
dismiss, citing ongoing violations of Rule 16. The day
before, he had received notice that the lead detective had
been charged with a DUI. Warren argued that, as this
was the third instance of untimely discovery and it
involved “critical impeachment information,” dismissal
was warranted. The district court found a Rule 16
violation, noting the late disclosure deprived Warren of
adequate time to investigate, compounding the prejudice.
12 The district court concluded the appropriate remedy that
best served the purposes of Rule 16 was to exclude the
detective’s testimony.
¶ 28 Warren argues this pattern of untimely disclosures
demonstrates neglect — if not willful violations — and the district
court’s decision not to dismiss was unreasonable and unfair.
¶ 29 We review a district court’s rulings on discovery issues and
sanctions for abuse of discretion. People v. Tippet, 2023 CO 61,
¶ 34; see People v. Daley, 97 P.3d 295, 298 (Colo. App. 2004) (“The
choice of an appropriate sanction for a violation of a discovery rule
lies within the sound discretion of the trial court.”). We will reverse
a court’s discovery sanction only when it is “manifestly arbitrary,
unreasonable, or unfair.” Tippet, ¶ 35 (quoting People v. Castro,
854 P.2d 1262, 1265 (Colo. 1993)).
¶ 30 Crim. P. 16 requires the prosecution to make certain material
and information in possession or control available “as soon as
practicable” but not later than twenty-one days after a defendant’s
first appearance. Crim. P. 16(I)(b)(1). Courts have recognized the 13 purpose of Rule 16 “is to advance the search for truth” and to deter
discovery-related misconduct. People v. Dist. Ct., 793 P.2d 163, 168
(Colo. 1990); see also People v. Cobb, 962 P.2d 944, 949 (Colo.
1998); People v. Lee, 18 P.3d 192, 196 (Colo. 2001).
¶ 31 To remedy a Rule 16 violation, a court must strike a balance
between “protecting the integrity of the truth-finding process and
deterring discovery-related misconduct.” Lee, 18 P.3d at 196.
Courts must consider several factors when fashioning discovery
sanctions: “(1) the reason for and degree of culpability associated
with the violation; (2) the extent of resulting prejudice to the other
party; (3) any events after the violation that mitigate such prejudice;
(4) reasonable and less drastic alternatives to exclusion; and (5) any
other relevant facts.” Tippet, ¶ 37 (quoting Cobb, 962 P.2d at 949).
¶ 32 Here, we conclude the district court properly considered these
factors in determining the appropriate sanctions for the Rule 16
violations. Specifically, it found that, in both Rule 16 violations, the
prosecution acted in good faith and that neither discovery violation
was willful. In one instance, the prosecution conceded that a
discovery violation had occurred and that Warren was entitled to a
14 timely notification. Further, in excluding the testimony of the
detective, the district court noted the need to balance the prejudice
that occurred against the need to find the least severe sanction to
effectuate procedural fairness.
¶ 33 Still, Warren argues the sanctions the district court issued
were insufficient in light of the prosecution’s repeated untimely
disclosures. However, the exclusion of the detective’s testimony
was more than sufficient. See People v. Whittington, 2024 CO 65, ¶
20 (“[W]e have recently emphasized that a court should generally
avoid excluding evidence as a sanction because exclusion is a
drastic remedy that may affect the outcome of the trial, provide a
windfall to the party against whom the evidence would have been
offered, or otherwise hinder the search for the truth.”). As the
district court explained, the prejudice could not be cured by way of
continuance due to the speedy trial deadline. Here, considering the
totality of the circumstances, striking the detective’s testimony was
the least severe sanction available. See Lee, 18 P.3d at 198 (“[T]he
exclusion of evidence would have been appropriate only where a
15 less severe sanction, such as a continuance, would be inadequate.”
(citing Dist. Ct., 793 P.2d at 168-69)).
¶ 34 For these reasons, the district court did not abuse its
discretion and appropriately remedied the Rule 16 violations.
III. Disposition
¶ 35 The judgment is affirmed.
