Summary

The Montana Supreme Court affirmed a lower court's decision in State v. Trombley, ruling that the state's bail jumping statute (§ 45-7-308, MCA) is not unconstitutionally vague. The court found that the statute sufficiently defined the offense and that the State had alleged sufficient facts to establish probable cause.

What changed

The Montana Supreme Court, in the case of State v. Trombley (DA 24-0013), has affirmed a lower court's judgment finding the defendant guilty of felony bail jumping under § 45-7-308, MCA. The appellant argued that the statute was unconstitutionally vague and that the State failed to allege sufficient facts to establish probable cause, specifically regarding the absence of a "lawful excuse" for non-appearance. The Court rejected these arguments, finding the statute sufficiently clear and the State's allegations adequate.

This decision reinforces the enforceability of Montana's bail jumping statute. Legal professionals and defendants should be aware that claims of unconstitutional vagueness are unlikely to succeed if the statute provides fair notice of prohibited conduct. The ruling also clarifies that the State need not explicitly allege the absence of a "lawful excuse" in its initial probable cause determination for bail jumping charges, as this is an element the defense may need to raise.

What to do next

  1. Review Montana Statute § 45-7-308, MCA, regarding bail jumping requirements.
  2. Ensure all court appearances are properly scheduled and attended to avoid charges.
  3. Consult legal counsel if facing charges related to bail jumping or statutory vagueness.

Clerk
Justice Laurie McKinnon delivered the Opinion of the Court.

¶1 Michael Ross Trombley (Trombley) appeals from the denial of his motion to

dismiss and the subsequent written judgment entered against him finding him guilty of Bail

Jumping, a felony in violation of § 45-7-308, MCA, entered in the Twentieth Judicial

District Court, Lake County, on November 9, 2023. Trombley contends that § 45-7-308,

MCA, is unconstitutionally vague and that the State failed to allege sufficient facts to

establish probable cause that Trombley had committed Bail Jumping when the State did

not allege any facts to show that Trombley did not have a “lawful excuse” when he failed

to appear at the court date he was ordered to attend. We affirm.

¶2 We restate the issues on appeal as follows:

  1. Whether Montana’s offense of Bail Jumping, codified at § 45-7-308, MCA,
    is unconstitutionally vague.

  2. Whether the State alleged sufficient facts to establish probable cause for the
    offense of Bail Jumping when it did not allege any facts to show that
    Trombley did not have a “lawful excuse” not to appear at the court hearing
    he was ordered to attend.

FACTUAL AND PROCEDURAL BACKGROUND

¶3 On January 19, 2023, Trombley appeared before the District Court on a Petition to

Revoke Probation for an unrelated felony. The District Court released Trombley from

custody on the condition that he appear for an Adjudicatory Hearing on February 16, 2023.

Trombley failed to appear at this hearing. The State filed an Information on February 21,

2023, charging Trombley with Bail Jumping, alleging that:

On or about the 16th day of February, 2023 at 9:00 a.m., in Lake County,
Montana, the Defendant MICHAEL ROSS TROMBLEY, having been set at
liberty with security by court order, in proceedings involving felony criminal

2
charges, upon the condition that he would subsequently appear for the
adjudicatory hearing on the 16th day of February, 2023 at 9:00 a.m. in the
District Courtroom, Lake County Courthouse, Polson, Montana, purposely
failed, without lawful excuse, to appear at that time and place.

The District Court issued a warrant for Trombley’s arrest. Officers arrested Trombley on

May 4, 2023, approximately ten weeks after the State filed its Information charging

Trombley with Bail Jumping. Trombley appeared before the District Court and entered a

plea of not guilty.

¶4 Trombley subsequently filed a motion to dismiss on July 25, 2023. In his motion to

dismiss, Trombley argued that the State failed to allege any facts to show that Trombley

purposely tried to miss his court appearance and that any number of reasons, such as illness

or transportation issues, could have prevented him from appearing at his court hearing.

Trombley further asserted that the State had failed to allege sufficient probable cause since

the clerk of court, who swore an affidavit in support of the Information, lacked personal

knowledge as to Trombley’s reasons for failing to appear at his court hearing. Lastly,

Trombley argued that § 45-7-308, MCA, is void for vagueness in the absence of a statutory

definition of “lawful excuse” and further impermissibly shifts the burden of proof onto a

criminal defendant who has no obligation to speak and would be forced to guess at what

would constitute a “lawful excuse.” After briefing and oral argument, the District Court

denied Trombley’s motion to dismiss on September 11, 2023.

¶5 Trombley entered into a global plea agreement whereby one of the charges he

pleaded to was Bail Jumping, reserving his right to appeal the denial of his motion to

dismiss. On September 21, 2023, Trombley admitted to the facts constituting the elements

3
of Bail Jumping, affirming that he failed to appear at his scheduled court hearing and that

he did not have a lawful excuse. The District Court sentenced Trombley to two years

incarceration at Montana State Prison in the instant case to run consecutively with his

sentences for the other offenses.

STANDARDS OF REVIEW

¶6 “Whether a statute is constitutional is a question of law” and we therefore “review

a district court’s application of the Constitution to determine if it is correct.” State v.

Stanko, 1998 MT 321, ¶ 14, 292 Mont. 192, 974 P.2d 1132. We begin our analysis with a

presumption that a challenged statute is constitutional. State v. Thirteenth Jud. Dist. Ct.,

2009 MT 163, ¶ 23, 350 Mont. 465, 208 P.3d 408; State v. Knudson, 2007 MT 324, ¶ 12,

340 Mont. 167, 174 P.3d 469. “The person challenging a statute’s constitutionality bears

the burden of proving it unconstitutional beyond a reasonable doubt.” Knudson, ¶ 12; see

also Thirteenth Jud. Dist. Ct., ¶ 23. Where possible, it is the duty of courts to construe

statutes to avoid an unconstitutional interpretation. Thirteenth Jud. Dist. Ct., ¶ 23; Stanko,

¶ 15.

¶7 Finally, we apply the de novo standard of review to mixed questions of law and fact

involving a motion to dismiss for lack of probable cause. State v. Giffin, 2021 MT 190,

¶ 11, 405 Mont. 78, 491 P.3d 1288 (citations omitted).

DISCUSSION

¶8 1. Whether Montana’s offense of Bail Jumping, codified at § 45-7-308, MCA, is
unconstitutionally vague.

4
¶9 Both the United States Constitution and the Montana Constitution provide that the

State shall not deprive a person of life, liberty, or property without due process of law.

U.S. Const. amend. XIV; Mont. Const. art. II, § 17. Essential to due process is that “an

enactment is void for vagueness if its prohibitions are not clearly defined.” Grayned v.

City of Rockford, 408 U.S. 104, 108, 92 S. Ct. 2294, 2298 (1972); see also Knudson, ¶ 18.

The doctrine of void for vagueness serves two critical principles. First, laws must give a

person of ordinary intelligence notice of what conduct is prohibited so that person may

conform his or her conduct to the law. State v. Dixon, 2000 MT 82, ¶ 28, 299 Mont. 165,

998 P.2d 544; Greyned, 408 U.S. at 108, 92 S. Ct. at 2298-99. “Vague laws may trap the

innocent by not providing fair warning.” State v. Dugan, 2013 MT 38, ¶ 66, 369 Mont. 39,

303 P.3d 755 (citations omitted). Second, to prevent arbitrary and discriminatory

enforcement, laws must provide explicit standards for those who apply them because a

vague law impermissibly delegates basic policy matters to policemen, judges, and juries

for resolution on an ad hoc and subjective basis, with the attendant dangers of arbitrary and

discriminatory application. Dugan, ¶ 66 (citations omitted). This second principle—to

prevent arbitrary and discriminatory enforcement—is the most important concern when

determining whether a law is void for vagueness. Stanko, ¶ 21 (quoting Kolender v.

Lawson, 461 U.S. 352, 357-58, 103 S. Ct. 1855, 1858 (1983)). Thus, we apply a two-part

test when examining whether a statute is void for vagueness: (1) whether the statute

5
provides fair notice of what conduct is prohibited1 and (2) whether the statute provides

minimal guidelines sufficient to govern enforcement. Knudson, ¶ 19 (citing Dixon, ¶ 27).

¶10 A statute may be challenged as unconstitutionally vague on two different grounds:

“(1) because the statute is so vague that it is rendered void on its face; or (2) because it is

vague as applied in a particular situation.” Thirteenth Jud. Dist. Ct., ¶ 24. “A statute is

void on its face ‘if it fails to give a person of ordinary intelligence fair notice that his

contemplated conduct is forbidden.’” Dugan, ¶ 25 (quoting State v. Nye, 283 Mont. 505,

513, 943 P.2d 96, 101 (1997)). The omission of exhaustive definitions of every term

employed in a statute does not render it automatically vague where the meaning of the

statute is clear and it provides sufficient notice to a defendant of what conduct is prohibited.

Dugan, ¶ 69. Where a challenged statute is “reasonably clear in its application to the

conduct of the person bringing the challenge, it cannot be stricken for vagueness.” Dugan,

¶ 20 (citations omitted). In other words, “[a] plaintiff who engages in some conduct that

is clearly proscribed cannot complain of the vagueness of the law as applied to the conduct

of others.” Dixon, ¶ 18 (quoting Vill. of Hoffman Ests. v. Flipside, Hoffman Ests., Inc., 455

U.S. 489, 495, 102 S. Ct. 1186, 1191 (1982)). “The requirement of a mental state to do a

prohibited act can render an otherwise vague or indefinite statute constitutional.” Dugan,

¶ 70. In an as-applied challenge, the statute is examined “in light of the conduct with which

1
Our case law, borrowing language from Kolender has used the term “actual notice,” however it
is clear that “actual notice,” as that term is traditionally understood, is not required to bring a void
for vagueness challenge. See Stanko, ¶ 21; Dixon, ¶ 27; Knudson, ¶ 19; Dugan, ¶ 67.
6
the defendant is charged in order to determine whether the defendant could have reasonably

understood that his conduct is proscribed.” Knudson, ¶ 21 (quoting Dixon, ¶ 28).

¶11 We now turn to Trombley’s as-applied challenge to Montana’s bail-jumping statute.

Trombley argues that the requirement that he provide a “lawful excuse” for his failure to

appear at a specified time and place impermissibly shifts the burden of proof from the State

to the defendant—that it is the State’s burden to prove that he did not have a lawful excuse.

He further asserts that, given the purported indefiniteness of the statute, he would have

risked self-incrimination by offering an excuse since he would have had to guess at what

would constitute a lawful excuse. The State answers that Trombley lacks standing to bring

an as-applied challenge because his conduct clearly falls within the scope of the

bail-jumping statute since he was set at liberty by the District Court and ordered to appear

on a specified time and place and did not appear. The State further argues that even if

Trombley had sought to explain his non-appearance to the District Court, at that point he,

regardless of his excuse, had already failed to appear and thus had an incentive to offer

some justification in his defense.

¶12 Section 45-7-308, MCA, provides: “[a] person commits the offense of bail-jumping

if, having been set at liberty by court order, with or without security, upon condition that

the person will subsequently appear at a specified time and place, the person purposely

fails without lawful excuse to appear at that time and place.” Trombley points this Court

to a decision by the Washington Supreme Court in State v. Hilt, 662 P.2d 52 (Wash. 1983),

which found that its state’s bail-jumping statute, which included the phrase “without lawful

excuse,” was unconstitutionally vague. There, the Court understood “without lawful

7
excuse” to be one of three elements to Bail Jumping. Hilt, 662 P.2d at 52. The Court drew

from a line of cases finding similar phrases to be unconstitutionally vague and held that,

“[t]he bail jumping statute is equally deficient in terms of providing guidelines to the

meaning of lawful excuse.” Hilt, 662 P.2d at 53. Thus, “predicting its potential application

would be a guess, at best.” Hilt, 662 P.2d at 53. The Washington Supreme Court later

clarified that the concept of “lawfulness” is not inherently unconstitutionally vague. State

v. Smith, 759 P.2d 372, 375 (Wash. 1988).

¶13 Conversely, the Massachusetts Appeals Court came to a different conclusion when

examining its statute for Bail Jumping which provides that a person “who fails without

sufficient excuse to so appear shall be punished[.]” Commonwealth v. Love, 530 N.E.2d

176, 177 (Mass. App. Ct. 1988). In Love, the Massachusetts court observed “the vagueness

doctrine ‘is not a principle designed to convert into a constitutional dilemma the practical

difficulties in drawing criminal statutes both general enough to take into account a variety

of human conduct and sufficiently specific to provide fair warning that certain kinds of

conduct are prohibited.’” Love, 530 N.E.2d at 179 (quoting Colten v. Kentucky, 407 U.S.

104, 110, 92 S. Ct. 1953, 1957 (1972)). Regarding the first element in a vagueness

challenge—fair notice to the defendant—the court reasoned that its own statute, like many

other jurisdictions, required a “willful” failure to appear and that the “present defendant, in

reason, could apprehend within rough bounds where his duty lay, and these would

correspond with the scope of the statute as described by the judge.” Love, 530 N.E.2d at

179-80. Concerning the second element—minimal guidelines sufficient to govern

enforcement—the court observed that “[s]uch a standard is not impermissibly vague even

8
though reasonable minds might differ whether particular conduct at the periphery of the

‘core’ comports with it: the jury decide the question under instructions, as they do in easier

cases to which the standard speaks more clearly.”2 Love, 530 N.E.2d at 179. Upon noting

that the decision in Hilt “may be losing strength in precedent” in light of more recent cases,

the Massachusetts court further observed that “[i]t is noteworthy that the Model Penal

Code’s bail-jumping provision, § 242.8, uses the very expression ‘without lawful excuse.’”

Love, 530 N.E.2d at 180 (quoting Model Penal Code § 242.8 (Am. L. Inst. 1962)); see

Love, 530 N.E.2d at 180, n.14 (collecting Washington Supreme Court cases). Indeed,

Montana’s criminal code is based on a modified version of the Model Penal Code. State

v. Mills, 2018 MT 254, ¶ 19, 393 Mont. 121, 428 P.3d 834.

¶14 The Model Penal Code and Commentaries on Bail Jumping and Burden of Proof

provide helpful insight into the meaning and purpose of Montana’s bail-jumping statute.

The purpose of the bail-jumping statute “is to deter those who would obstruct justice by

failure to appear for trial or service of sentence.” Model Penal Code § 242.8, cmt. 2 (Am.

L. Inst. 1980). The provision “without lawful excuse” is “designed to give indeterminate

scope to the kinds of excuses for non-appearance that the courts may choose to adopt.”

Model Penal Code § 242.8, cmt. 4. Circumstances causing a defendant’s non-appearance,

such as accident, illness, and the like, are “[o]bviously” exempt from liability, yet “the full

range of excuses that might be judged valid in one or another circumstance is impossible

2
The trial court instructed the jury that examples of sufficient excuses included “serious illness,
accident, confinement as by kidnapping” and examples of insufficient excuses included “simple
refusal to face responsibility, simple intent to escape punishment for wrongdoing or to frustrate
justice.” Love, 530 N.E.2d at 178 n.5.
9
to identify in advance.” Model Penal Code § 242.8, cmt. 3. An affirmative defense is one

which “involves a matter of excuse or justification peculiarly within the knowledge of the

defendant on which he can fairly be required to adduce supporting evidence.” Model Penal

Code § 1.12(3)(c) (Am. L. Inst. 1985).3 The initial burden of showing an affirmative

defense lies with the defendant and the prosecution does not have a duty to negate such a

defense unless and until supporting evidence is adduced by the defendant. Model Penal

Code § 1.12, cmt. 3. Any affirmative defense which a defendant must prove by a

preponderance of the evidence “must plainly appear.” Model Penal Code § 1.12,

Explanatory Note (internal quotations omitted). Absent such a plain indication that an

affirmative defense must be proven by a preponderance of the evidence, “[i]t should suffice

to put the prosecution to its proof that the defendant shows enough to justify a reasonable

doubt on the issue.” Model Penal Code § 1.12, cmt. 3. The American Law Institute did

not think it was inherently unfair that an affirmative defense may impose pressure upon a

defendant to testify. Model Penal Code § 1.12, cmt. 4; see also Barnes v. United States,

412 U.S. 837, 847, 93 S. Ct. 2357, 2362 (1973) (“Introduction of any evidence, direct or

circumstantial, tending to implicate the defendant in the alleged crime increases the

pressure on him to testify. The mere massing of evidence against a defendant cannot be

regarded as a violation of his privilege against self-incrimination.”); State v. Emmons, 936

A.2d 459, 464 (N.J. Super. Ct. App. Div. 2007) (“The determination whether to present

3
In contrast to the Model Penal Code, South Dakota’s bail-jumping statute, for example, is a strict
liability offense. State v. Vogel, 315 N.W.2d 324, 326 (S.D. 1982) (citing S.D. Codified Laws
§ 23A-43-31).
10
exculpatory evidence [in defense of Bail Jumping] is simply part of the defense’s strategic

decision-making process that occurs in any criminal case.”). We now apply this Court’s

two-part void for vagueness inquiry to the bail-jumping statute and inquire into whether it

provides fair notice to a defendant and minimal guidelines sufficient to govern law

enforcement. Knudson, ¶ 19 (citation omitted).

¶15 Here, Trombley was set at liberty by the District Court under the condition that he

appear at his Adjudicatory Hearing on February 16, 2023. He failed to appear at the time

and place specified by the District Court. A person of ordinary intelligence in Trombley’s

circumstances would have had fair notice that he was required by law to attend this hearing

and that a failure to do so could result in criminal penalties. If Trombley had some

compelling reason for failing to appear, such as an illness, accident, or the like, he would

have had a strong incentive to disclose that reason to the District Court. Instead, the record

does not show any communications from Trombley about his whereabouts during the

approximately ten-week period between his Adjudicatory Hearing and his arrest on May 4,

  1. Such an extended period of absence from his criminal proceedings evidences a

purpose to “obstruct justice by failure to appear for trial or service of sentence.” Model

Penal Code § 242.8, cmt. 2.

¶16 The provision “without lawful excuse” clearly provided Trombley an opportunity

to raise an affirmative defense, for which he carried the initial burden of production, to his

failure to appear at his hearing. The decision of whether or not to take advantage of the

opportunity to raise a lawful excuse as an affirmative defense did not force Trombley to

incriminate himself, but, rather, was “simply part of the defense’s strategic

11
decision-making process that occurs in any criminal case.” Emmons, 936 A.2d at 464.

Trombley’s argument that he would have risked self-incrimination since he would have

had to guess what constitutes a lawful excuse is without merit because it presupposes that

he had an array of mutually exclusive reasons for his failure to appear on February 16,

2023, but he had to choose only one. Had Trombley met his burden of production and

adduced some supporting evidence that he did have a lawful excuse, it would have been

the State’s burden to prove to a jury beyond a reasonable doubt that he did not have a lawful

excuse. To be sure, individual jurors may have differed in their appraisal of whether

Trombley did not have a lawful excuse for his failure to appear. However, the statute’s

mental state element of “purposely” mitigates any vagueness concerns as it required proof

beyond a reasonable doubt that it was Trombley’s conscious object to fail to appear on

February 16, 2023, not that circumstances beyond his control prevented him from attending

his Adjudicatory Hearing. See § 45-2-101(65), MCA, (defining “purposely”); Dugan,

¶ 70. The State’s burden of proving beyond a reasonable doubt to a unanimous jury that

Trombley was set at liberty by a court order and purposely failed to appear on February 16,

2023, without a lawful excuse mitigates any concern as to whether § 45-7-308, MCA,

provides minimal guidelines sufficient to govern law enforcement. Since the bail-jumping

statute is reasonably clear in its application to Trombley’s conduct during the ten-week

period where he absconded from justice, we conclude § 45-7-308, MCA, cannot be stricken

for vagueness. Dugan, ¶ 70. Thus, Trombley’s as-applied challenge fails. Because

Trombley has engaged in the proscribed conduct, he cannot complain that the law is

12
facially vague as applied to others. Trombley’s facial challenge therefore fails as well.

Dugan, ¶ 70.

¶17 Accordingly, the District Court did not err when it denied Trombley’s motion to

dismiss because § 45-7-308, MCA, is not void for vagueness as applied to Trombley.

¶18 2. Whether the State alleged sufficient facts to establish probable cause for the
offense of Bail Jumping when it did not allege any facts to show that Trombley did
not have a “lawful excuse” not to appear at the court hearing he was ordered to
attend.

¶19 Trombley asserts that “without lawful excuse” is one of three elements to the

bail-jumping statute and therefore the State had the burden of alleging facts to make it

probable that Trombley did not have a “lawful excuse.” Trombley reasons that because

the Legislature did not explicitly define “lawful excuse” as an affirmative defense, as it has

done with affirmative defenses in other parts of the criminal code, it must be a necessary

element. Thus, he asserts, the State had the burden of alleging facts to indicate that

Trombley did not have a lawful excuse for his failure to appear at his hearing. The State

responds that the charging Information apprised Trombley of the charge against him and

the facts in support of the bail-jumping offense, and that Trombley’s mental state was

properly a question for the jury to determine. The State likens “lawful excuse” to an

affirmative defense to which Trombley had a significant interest in presenting evidence

that he did have a lawful excuse when he failed to appear at his hearing. We agree with

the State.

¶20 The requirements for the filing of an information and the supporting affidavit are

governed by statute and set forth in § 46-11-201, MCA, which provides:

13
(1) The prosecutor may apply directly to the district court for permission to
file an information against a named defendant . . . .

(2) An application must be by affidavit supported by evidence that the
judge . . . may require. If it appears that there is probable cause to believe
that an offense has been committed by the defendant, the judge . . . shall grant
leave to file the information, otherwise the application is denied.

Giffin, ¶ 14. A court determines the sufficiency of the charging documents “by reading the

information together with the affidavit in support of the motion to file the information.”

Giffin, ¶ 15 (quoting State v. Elliot, 2002 MT 26, ¶ 26, 308 Mont. 227, 43 P.3d 279). The

evidentiary threshold for establishing probable cause is lower than the evidence necessary

to establish that a person is guilty of a particular offense. Giffin, ¶ 15. “The supporting

affidavit does not have to make out a prima facie case the defendant committed an offense;

rather, a probability that the defendant committed the offense is sufficient.” Giffin, ¶ 15.

However, the charging documents “must reasonably apprise the accused of the charges

against him to enable him an opportunity to prepare a defense.” Giffin, ¶ 15. Upon a

court’s finding of probable cause, whether a defendant had the requisite mental state is a

question of fact for the jury. State v. Tichenor, 2002 MT 311, ¶ 21, 313 Mont. 95, 60 P.3d

454.

¶21 Here, the Affidavit and the Information charging Trombley with Bail Jumping

supported the District Court’s finding that the State had probable cause. The charging

documents identified the time and place that Trombley was ordered to appear, that he had

been set at liberty upon the condition of his appearance at such a time and place in a felony

proceeding, that he had purposely failed to appear without a lawful excuse, and that as of

14
the time of the Information he had not appeared or given a lawful excuse for his failure to

appear. These allegations established that it was probable that Trombley committed the

offense of Bail Jumping, reasonably apprised Trombley of the charge against him, and

provided him with sufficient opportunity to prepare a defense. Trombley’s argument that

because the Legislature did not explicitly identify “lawful excuse” as an affirmative

defense as it has done elsewhere in the criminal code elevates form over substance. See

§§ 45-2-211 (consent); -212 (compulsion); -213 (entrapment), MCA. As the American

Law Institute explains, “it is desirable that, so far as possible, such [affirmative] defenses

be identified specifically by the legislature.” Model Penal Code § 1.12, cmt. 4. “It is,

however, clear that as a drafting matter it is less than feasible to make the designation in

all situations where casting an evidential burden on defendants would promote the fair

administration of the penal law and raise no constitutional objection.” Model Penal Code

§ 1.12, cmt. 4. Trombley’s reason for not appearing at his Adjudicatory Hearing is

peculiarly within his own knowledge: he could fairly have been required to adduce

evidence in support of this affirmative defense, but he chose not to do so. Model Penal

Code § 1.12(3)(c). We find it difficult to conceive how the State could even allege facts to

establish whether an exception to the bail-jumping statute did not exist.” The State is not

required to negate any statutory exception to an offense in its indictment, information, or

complaint. Model Penal Code § 1.12, cmt. 3, n.16. Section 45-7-308, MCA, does not

“require the disproof of an affirmative defense unless and until there is evidence

supporting” an affirmative defense that Trombley had a lawful excuse not to appear at his

court hearing. Model Penal Code § 1.12(2)(a).

15
¶22 Accordingly, the District Court correctly denied Trombley’s motion to dismiss

because the State alleged sufficient facts to establish probable cause that Trombley

committed the offense of Bail Jumping.

CONCLUSION

¶23 Section 45-7-308, MCA, is reasonably clear in its application to the conduct of

Trombley, who was released by the District Court upon the condition that he appear at his

court hearing on February 16, 2023, but failed to do so and was arrested on a warrant for

Bail Jumping nearly ten weeks later on May 4, 2023 and, therefore, it cannot be stricken

for vagueness. The State is not required to allege facts which would negate the existence
