Justice Jim Rice delivered the Opinion of the Court. 

¶1 Katie Irene Garding (Garding) appeals from the Judgment entered by the Fourth

Judicial District Court, Missoula County, regarding her conviction for the offenses of 

vehicular homicide while under the influence, failure to stop immediately at the scene of 

an accident involving an injured person, and driving without a valid driver’s license. We 

affirm and address the following issues on appeal:

¶2 1. Did the District Court err by limiting the Defendant’s cross-examination of the 

State’s informant?

¶3 2. Did the District Court err by preventing the Defendant’s expert forensic 

pathologist from testifying about matters not disclosed through discovery?

¶4 3. Did the District Court err by permitting an undisclosed expert witness to testify 

for the State?

FACTUAL AND PROCEDURAL BACKGROUND

¶5 This case involves the tragic death of Bronson Parsons (Parsons) due to injuries 

sustained during a hit-and-run vehicle-pedestrian accident in the early morning hours of 

January 1, 2008. At approximately 1:40 a.m., Parsons and Daniel Barry (Barry) were 

walking along the right-hand shoulder of Highway 200 and toward the Reno Casino (the 

Reno) in East Missoula to participate in the Bar’s last call of the night. When they were 

about 300 yards from the Reno, a dark-colored SUV struck Parsons from behind and 

carried him a short distance before he slid off the side of the hood. The SUV veered off 

the road, corrected itself, and then accelerated westward toward Missoula. Parsons 

remained on his back in the roadway, having sustained fatal blunt force trauma to the 

back of his head. 
3

¶6 In the darkness, Barry was able to identify the fleeing vehicle only as a bigger, 

dark-colored SUV or truck. Barry also thought the vehicle had a deer guard or something 

else reinforcing its frontend. Deborah Baylor (Baylor), who was driving east along 

Highway 200 at the time of the collision, saw a dark-colored vehicle strike Parsons with 

its passenger side. Baylor explained that she heard a pop or a bang and then saw Parsons 

fly off the side of the vehicle and land in the roadway. Neither Baylor nor Barry heard 

any glass breaking during the accident. 

¶7 Trooper Novak of the Montana Highway Patrol soon arrived at the scene and 

conducted an investigation. He looked for anything of evidentiary value, such as broken 

glass or damaged vehicle parts, but was only able to find a set of tire tracks on the 

shoulder of the road, which he later photographed. Trooper Novak was not able to

precisely identify the point of impact. 

¶8 Other law enforcement officers were alerted about the accident, and about ten 

hours later Trooper Hader of the Montana Highway Patrol stopped Garding to investigate 

her cracked windshield. Garding was driving a black 1994 Chevy Blazer with a unique,

aftermarket steel bumper protruding from the frontend. Trooper Hader then believed that 

the accident had involved a full-frontal crash and that the subject vehicle would have 

extensive frontend damage. When Trooper Hader did not observe any such damage, he

cited Garding for driving without a license and arrested her boyfriend, James Bordeaux

(Bordeaux), who was also in the vehicle, on an out-of-state warrant. Law enforcement

would take no further action against Garding for some time.
4

¶9 Law enforcement initially suspected that Gabrielle Weiss (Weiss) had hit Parsons 

with her vehicle, a green 1995 S-10 Chevy Blazer, due to an unusual 911 call that she 

placed around the time of the accident.1 During that call Weiss mistakenly identified 

herself as being in East Missoula that night. Law enforcement later confirmed that she 

had actually been in the Blue Mountain area that night. During the investigation, law 

enforcement impounded Weiss’s vehicle and submitted its bumper to the FBI for 

laboratory examination. Although the bumper contained a fabric impression from a pair 

of jeans,

2

no conclusive results were obtained. Weiss was not charged and the case went 

cold. 

¶10 On December 22, 2008, almost one year after the accident, Tueray Cornell 

(Cornell), then an inmate at the Missoula County Detention Center, contacted Trooper 

Hader to report that he had information about the incident. Cornell explained that 

Garding had driven to his house on January 1, 2008, and told him that she had hit a deer. 

Cornell used duct tape to repair Garding’s broken light cover by taping it back in place. 

Following up on this lead, law enforcement discovered that Garding’s Blazer had been 

repossessed and resold. The new owner explained that the Blazer had broken down 

almost immediately upon purchase, but otherwise remained in the same condition. The 

right front fog lamp was affixed with duct tape.

 

1 Weiss admitted to being highly intoxicated at the time she called 911. Her boyfriend had 

recently been stabbed, and she was attempting to drive him to the hospital.

2 Weiss testified that her boyfriend, who was wearing jeans, jumped onto the hood of her vehicle 

during an argument on December 31, 2007.
5

¶11 Meanwhile, Bordeaux, one of Garding’s passengers on the night of the accident 

and now her ex-boyfriend, was incarcerated in Missoula on a burglary charge. At the

omnibus hearing in Bordeaux’s case, the State checked the omnibus hearing form to 

indicate that it intended to pursue a Persistent Felony Offender (PFO) designation under 

§ 46-18-502(1), MCA, against Bordeaux, which would permit a district court to sentence 

him to up to 100 years in prison. However, the State did not discuss or pursue this 

possibility further. 

¶12 As part of the investigation into Garding, Trooper Hader contacted Bordeaux, who 

related that on the day of the accident, Bordeaux and Garding started drinking around 

11:00 a.m. After several hours of drinking at Red’s Bar in Missoula, they met Paul 

McFarling (McFarling) and drove to East Missoula in Garding’s Blazer, drinking Black

Velvet and smoking marijuana on the way. The three continued to drink throughout the 

afternoon and evening, including at the Reno. Sometime after midnight, they drove to 

Red’s Bar in Missoula and remained there until 1:30 a.m. They then returned to East 

Missoula in Garding’s Blazer to try to purchase cocaine. McFarling, who was sitting in 

the backseat, pulled out a gun and attempted to show it to Garding and Bordeaux. 

Bordeaux, who was sitting in the front passenger’s seat, turned around and started 

arguing with McFarling, threatening to “slap him” and telling Garding to pull over so he 

could kick McFarling out of the car. Possibly distracted by these events, Garding struck 

Parsons from behind with the passenger’s side of her vehicle. Bordeaux stated that he 

spun around in his seat just in time to see a person flying through the air and hear 
6

Garding say, “I hit somebody.” Garding did not stop the vehicle, but instead drove back

to Missoula and stayed the night at McFarling’s house. 

¶13 In exchange for providing this testimony, the State offered Bordeaux a plea deal

whereby he would testify against Garding and plead guilty to the burglary, and in return,

the State would recommend that he receive a five-year suspended sentence. The possible 

PFO designation was not discussed or mentioned in the parties’ written plea agreement. 

Obtaining Bordeaux’s cooperation, the State charged Garding with Parsons’ death.

¶14 At trial, Garding sought to impeach Bordeaux’s credibility. In her opening 

statement, Garding’s counsel stated, “the State wants you to believe that [Bordeaux] did 

not get any deal for his original sentence. As I mentioned, he was facing 20 years in 

prison [for burglary], plus an additional 5 to 100 years for being a persistent felony 

offender.” However, when Garding’s counsel began her cross-examination of Bordeaux,

the District Court granted the State’s objection to any mention of the potential PFO

designation, limiting the scope of Garding’s questioning in this regard to the burglary 

charge and the contents of the plea agreement. 

¶15 The State called the medical examiner, Dr. Gary Dale (Dr. Dale), who testified 

that the location and size of Garding’s bumper was consistent with muscle tearing 

injuries in Parsons’ calves. Garding called Dr. Thomas Bennett (Dr. Bennett), a forensic 

pathologist, to challenge Dr. Dale’s testimony. Dr. Bennett testified that irregular 

bruising found on the exterior of Parsons’ calves would not have been caused by a 

bumper like Garding’s. When asked to explain the muscle tearing discussed by Dr. Dale,

the District Court sustained the State’s objection that Dr. Bennett’s report obtained in 
7

discovery had failed to mention muscle tearing and limited Dr. Bennett’s testimony to the 

bruising on Parsons’ calves.

¶16 The State also called Alice Ammen (Ammen) from the State Crime Lab to testify 

about her inspection of the victim’s clothing. During cross-examination, Ammen noted 

that the Crime Lab had the ability to analyze fabric impressions, such as the jeans 

impression left on Weiss’s bumper, although a different section of the lab handled that 

responsibility. To address this issue further, the State, still in its case in chief, called

Debra Hewitt (Hewitt), a fabric-impression expert from the State Crime Lab, who had not 

previously been listed as a witness. Over Garding’s objection, the District Court 

permitted Hewitt to testify regarding why a fabric impression analysis would not have 

been probative in this case. According to Hewitt, absent some unique defect or stitching,

the lab cannot distinguish between the impressions left by different pairs of jeans, and

because the impression found on Weiss’s bumper was not unique, the lab did nothing 

further. 

¶17 The jury convicted Garding of vehicular homicide while under the influence,

failure to stop immediately at the scene of an accident involving an injured person, and 

driving without a valid driver’s license. She appeals.

STANDARD OF REVIEW

¶18 We review a district court’s evidentiary rulings for abuse of discretion. State v. 

Bonamarte, 2009 MT 243, ¶ 13, 351 Mont. 419, 213 P.3d 457. A district court “abuses 

its discretion if it acts arbitrarily or unreasonably, and a substantial injustice results.” 

Bonamarte, ¶ 13. However, “[a] district court has broad discretion when determining the 
8

relevance and admissibility of evidence.” State v. Daniels, 2011 MT 278, ¶ 11, 362 

Mont. 426, 265 P.3d 623. In exercising its discretion, a district court remains bound by 

the Rules of Evidence or other applicable statutes. We review de novo a district court’s 

interpretation of an evidentiary rule or statute. We exercise plenary review for questions 

regarding constitutional law. Daniels, ¶ 11.

DISCUSSION

¶19 1. Did the District Court err by limiting the Defendant’s cross-examination of the 

State’s informant?

¶20 Garding argues that the District Court improperly limited her inquiry into 

Bordeaux’s bias or motive to testify falsely by not allowing her to cross-examine 

Bordeaux about his possible PFO designation. She explains that the possibility of

Bordeaux facing 100 years in prison is exactly the kind of bias or motive that should have 

been made known to the jury. The State counters that the only reference it made to a 

PFO designation was the check on the omnibus form, but that the matter was not further 

discussed and the State did not negotiate away a PFO designation in exchange for 

anything. The plea agreement contains no mention of a PFO sentencing enhancement, 

and thus the State argues that the District Court properly exercised its discretion to limit 

Garding’s inquiry.

¶21 The “accused’s right to demonstrate the bias or motive of prosecution witnesses is 

guaranteed by the [Confrontation Clause of the] Sixth Amendment,” State v. 

Gommenginger, 242 Mont. 265, 272, 790 P.2d 455, 460 (1990) (citations omitted), and 

the Montana Constitution, Mont. Const. art. II, § 24. The accused’s right to confront 
9

adverse witnesses is fundamental. State v. Parker, 2006 MT 258, ¶ 20, 334 Mont. 129, 

144 P.3d 831 (citing State v. Clark, 1998 MT 221, ¶ 20, 290 Mont. 479, 964 P.2d 766; 

Mont. Const. art. II, § 24). A defendant is to be given “broad latitude” in questioning the 

credibility and self-interest of witnesses. On Lee v. U.S., 343 U.S. 747, 757, 72 S. Ct. 

967, 973-74 (1952). “The Confrontation Clause ‘guarantees an opportunity for effective 

cross-examination, not cross-examination that is effective in whatever way, and to 

whatever extent, the defense might wish.’” State v. Nelson, 2002 MT 122, ¶ 19, 310 

Mont. 71, 48 P.3d 739 (citing State v. Jenkins, 2001 MT 79, ¶ 19, 305 Mont. 95, 23 P.3d 

201 (additional citations omitted) (emphasis in original)). A district court maintains 

broad latitude to limit cross-examination to those issues that are relevant. Nelson, ¶ 15. 

We have explained that “discretion in exercising control and excluding evidence of a 

witness’s bias or motive to testify falsely becomes operative only after the 

constitutionally required threshold level of inquiry has been afforded the Defendant.” 

Bonamarte, ¶ 16. 

¶22 In Nelson, an informant testified against Nelson after reaching a plea agreement 

with the Ravalli County prosecutor. Nelson, ¶ 11. During Nelson’s cross-examination of 

the informant, the State objected to the scope of Nelson’s questions. Nelson explained

that he wanted to cross-examine the informant about other charges filed against him in 

order to establish that the informant had a pattern of reaching plea deals and then 

testifying against co-defendants. The district court refused to allow this line of 

questioning. Nelson, ¶ 12. On appeal, Nelson argued that the district court’s limitation 

on the scope of his inquiry violated his right to confront his accuser. Nelson, ¶ 16. We 
10

disagreed, holding that Nelson had been afforded the constitutionally required level of 

inquiry. Nelson, ¶ 19. We found it persuasive that “nothing in the record indicate[d] that 

Ravalli County offered any plea arrangements to [the informant] based on” his other

alleged criminal activity, Nelson, ¶ 17, and that Nelson received wide latitude when 

cross-examining the informant about the actual contents of the plea agreement with 

Ravalli County, Nelson, ¶ 18. 

¶23 As in Nelson, Bordeaux’s plea agreement does not contain any reference to the

PFO designation. As the State notes, other than the check on Bordeaux’s omnibus 

hearing form, he was never notified that the State considered him to be a PFO. Garding 

generalizes that the state “‘routinely’ uses a PFO designation to encourage a deal,” and

cites Nelson for the proposition that a defendant’s right to confront is violated “when a 

court precludes questioning on the witness’s potential for bias or prejudice stemming 

from his interest in receiving leniency on other charges from the prosecuting office.” 

However, Garding failed to present any evidence that Bordeaux actually received

“leniency on other charges” regarding the PFO, as the following exchange between

counsel for Garding and the District Court illustrates: 

[Garding:] Your Honor, I’m arguing, though, I don’t—we don’t have to 

argue that he received benefit of them not filing for the persistent felony 

offender. What I’m asking is his state of mind when he was charged with 

the burglary, what he was facing, the penalties that he was facing, the 

consequences that he was facing for his motive to go and make a statement.

[District Court:] Well, absent the testimony the only thing I have is the 

plea agreement. So that’s what I’m limited to, the actual motives and—and 

discussions and focus in this case. Now if there’s something else, some

other evidence, I’m happy to consider it, but at this point I’m precluding 

getting into it [possible PFO designation].
11

¶24 After making this ruling, the District Court, as in Nelson, permitted Garding to 

cross-examine Bordeaux at length about his plea agreement with the State, including the 

following exchange:

[Garding:] Okay. And so two days after you provide this statement [about 

Garding], after your burglary charge has been pending for over two months, 

you go and enter a guilty plea on the burglary, right?

[Bordeaux:] Yes, ma’am.

[Garding:] Just two days after you give this statement.

[Bordeaux:] Yes, ma’am.

[Garding:] And you get a sentence that does not call for you to go to prison 

here in Montana, right?

[Bordeaux:] Yes.

[Garding:] And you get a sentence that allows you to be on probation, and 

you get to walk out those doors, and you’ve gone back to Missouri, right?

[Bordeaux:] Yes.

Based on our review of the record, it is clear that the District Court afforded Garding

sufficiently wide latitude in cross-examining Bordeaux about his bias and motivation to 

testify falsely to satisfy Garding’s right of confrontation. Garding inquired extensively 

into Bordeaux’s burglary charge, his plea agreement, and the timing of his statement 

against Garding. This inquiry, coupled with the lack of evidence that Bordeaux’s plea 

agreement was motivated in any way by a potential PFO designation, satisfies the 

constitutional requirement of an effective opportunity for cross-examination. See Nelson, 
12

¶¶ 15-19. Based on the foregoing, we hold that the District Court did not violate 

Garding’s constitutional rights, nor did it abuse its discretion in this instance.

3

 

¶25 2. Did the District Court err by preventing the Defendant’s expert forensic 

pathologist from testifying about matters not disclosed through discovery?

¶26 Garding argues that the District Court erred by not permitting Dr. Bennett to refute 

Dr. Dale’s testimony about the muscle tearing in Parson’s calves. During trial, Dr. Dale 

testified that Parsons sustained a “3-inch area of tearing or crushing of the muscle, the 

calf muscles, in both calves . . . above his heel.” However, when Garding attempted to 

question Dr. Bennett about this muscle tearing, the District Court sustained the State’s 

objection and limited Dr. Bennett’s testimony to the bruising found on Parsons’ calves:

[District Court:] We’re looking at [Dr. Bennett’s] opinion number four. 

Specifically limit—it specifically states “bruises” when indicating the 

linkage to the vehicle.

[Dr. Bennett:] Yes.

[District Court:] And so that’s what you’re limited to and not to the tearing 

of the muscle because that’s what was disclosed.

[Dr. Bennett:] Okay.

[District Court:] And so you understand that rule. Okay.

[Dr. Bennett:] Perfectly fine, judge. That’s the most important part 

anyway.

. . .

 

3

In her reply brief, Garding shifts the focus of her argument away from her cross-examination of 

Bordeaux to a discussion about the District Court’s ruling on a generic motion in limine filed by 

the State. Having reviewed the applicable documents, we find that our analysis in this case 

appropriately centers on the District Court’s decision to limit Garding’s cross-examination of

Bordeaux at trial, since the PFO issue was ultimately decided at that point.
13

[District Court:] When you disclose you’re generally limited to that area 

and that’s my ruling.

¶27 The State offers little justification, and, after review, we are unable to conclude 

there was an appropriate legal basis for the District Court’s exclusion of Dr. Bennett’s 

testimony. As Garding notes, “defense counsel may not be required to prepare or 

disclose summaries of witnesses’ testimony.” Section 46-15-323(8), MCA; State v. 

Huerta, 285 Mont. 245, 253, 947 P.2d 483, 488 (1997) (concluding that it was error to 

require the defendant to produce summaries of his witnesses’ testimony). Section 46-15-

323(6)(b), MCA, states that the names and addresses of defense experts, as well as their 

reports, shall be made available to the prosecutor. This was done here, and Dr. Bennett’s 

report mentions, contrary to the District Court’s ruling, Dr. Dale’s finding about the 

muscle tearing. Further, during trial, Garding’s counsel advised the District Court that 

Dr. Bennett would testify about “how people can obtain muscle tears” and “how blunt 

force trauma can create muscle tears” in accordance with M. R. Evid. 103(a)(2). Thus, 

we conclude that the District Court abused its discretion in limiting Dr. Bennett’s 

testimony to only Parsons’ bruising injuries. We now turn to the question of whether this 

error was harmless.

¶28 “The first step in conducting [a] harmless-error analysis is to determine whether 

the error is structural error or trial error.” State v. Stewart, 2012 MT 317, ¶ 45, 367 Mont.

503, 291 P.3d 1187 (citation omitted). Structural error affects the framework within 

which the trial proceeds. State v. Van Kirk, 2001 MT 184, ¶ 38, 306 Mont. 215, 32 P.3d 

735. Structural error is of “constitutional dimensions, precedes the trial, and undermines 
14

the fairness of the entire trial proceeding.” Stewart, ¶ 45. Examples include: errors in the 

jury selection process, deprivation of the right to counsel, and lack of an impartial trial 

judge. Structural error is not subject to harmless-error review and is automatically 

reversible. Van Kirk, ¶ 39 (citations omitted). Trial error, on the other hand, typically 

occurs during the presentation of a case to the jury. It can be reviewed qualitatively for 

prejudice relative to other evidence introduced during trial and, therefore, is not 

automatically reversible. Stewart, ¶ 45. 

¶29 Precluding Dr. Bennett’s testimony was not, in and of itself, an error affecting the 

framework in which the trial proceeded—it “did not contaminate the trial mechanism 

along the lines that a biased judge, lack of counsel, or a jury-selection error would,”

Stewart, ¶ 45. Thus, any error on the part of the District Court was trial error subject to 

Montana’s harmless error statute. That statute provides, “[a] cause may not be reversed 

by reason of any error committed by the trial court against the convicted person unless 

the record shows that the error was prejudicial,” and “[a]ny error, defect, irregularity, or 

variance that does not affect substantial rights must be disregarded.” Section 46-20-

701(1), (2), MCA. 

¶30 Garding argues that the District Court’s decision prejudiced her by barring the jury 

from properly evaluating whether her bumper “could have or could not have caused 

Parsons’ muscle tearing,” thereby preventing her from presenting a complete defense. 

She further argues that the State capitalized on this exclusion during its closing argument

by referencing the muscle tearing several times. Accordingly, Garding asserts that the 

District Court’s decision to limit Dr. Bennett’s testimony contributed to her conviction. 
15

¶31 In response to a claim that trial error may have contributed to a conviction, it 

“‘becomes incumbent on the State to demonstrate that the error at issue was not 

prejudicial.’” State v. Slavin, 2004 MT 76, ¶ 22, 320 Mont. 425, 87 P.3d 495 (citing Van 

Kirk, ¶ 42). To meet this burden in cases where a court ruling excludes testimony, the 

State must demonstrate that there was no reasonable possibility that the exclusion 

contributed to the conviction. Slavin, ¶ 22. 

¶32 Dr. Bennett was permitted to testify at length about the nature of Parsons’ bruises 

and the features of Garding’s bumper:

The bruises as described on the back and as seen in the photographs would 

not be caused by a bumper like that in the mechanism as described. That 

bumper with the square edges and so forth would not produce those 

irregular marks on the back of the calf. The bruises would be much more

characteristic. You would see lines of petechiae and so forth . . . . Again 

the bruising is not petechiae. There are regular deep bruises we see on the 

back of the calves. The bluish discoloration and so forth, the blue, it’s a 

curved, smooth surface, not this bumper. . . . [Garding’s bumper is] a 

3-inch bumper. The skin markings effectively . . . indicate this isn’t the 

bumper.

Dr. Bennett repeatedly testified that Garding’s vehicle did not cause the injuries to

Parsons’ calves. Each time, Dr. Bennett supported his opinion with extensive analysis of

the bruising, which he characterized to the jury as “the best way to look for the nature of 

that instrument [Garding’s bumper],” and to the District Court as “the most important 

part [of his testimony].”

¶33 Although the State mentioned muscle tearing during its closing argument, 

Dr. Bennett was still allowed to present the most critical aspects of his testimony to the 

jury—including his ultimate conclusion that Garding’s vehicle did not cause the injuries 
16

to Parsons’ calves. We believe this testimony sufficiently enabled the jury to weigh 

Dr. Bennett’s opinion against Dr. Dale’s. Therefore, we conclude that there was no 

reasonable possibility that Garding’s conviction resulted from the District Court’s

exclusion of this portion of Dr. Bennett’s analysis, and the error was harmless.

¶34 3. Did the District Court err by permitting an undisclosed expert witness to testify 

for the State?

¶35 Lastly, Garding argues that the District Court abused its discretion by allowing the 

State to call Hewitt to testify about fabric impressions analysis when she had not been 

previously disclosed as a witness. The State acknowledges that it did not disclose Hewitt

as a witness,

4

but offers that she was called only to briefly explain why fabric impression 

evidence from Weiss’s bumper was not analyzed after Garding raised the issue on 

cross-examination of Ammen. Garding counters that the effect of calling a surprise 

witness is both “devastating and prejudicial.”

¶36 A prosecutor, upon request, must provide the defendant with “the names, 

addresses, and statements of all persons whom the prosecutor may call as witnesses in the 

case in chief,” together with “all written reports or statements of experts who have 

personally examined the defendant or any evidence in the particular case . . . .” Section 

46-15-322(1)(a), (c), MCA. If the prosecutor fails to comply with these discovery 

provisions at any time, the court “may impose any sanction it finds just under the 

circumstances . . . .” Section 46-15-329, MCA. This statute provides a district court with 

 

4 According to the State, Hewitt was not disclosed because she never produced a report or 

completed any testing. 
17

the flexibility to impose sanctions, but does not mandate automatic exclusion for 

noncompliance. State v. Waters, 228 Mont. 490, 495, 743 P.2d 617, 621 (1987). 

¶37 It is generally inappropriate for the State to call an undisclosed expert witness in 

its case in chief. Here, however, the District Court afforded Garding ample time to 

interview Hewitt and indicated a willingness to grant more time if necessary. Hewitt’s 

testimony was to a narrow issue and was brief. Garding thoroughly cross-examined 

Hewitt about the failure to compare the fabric impressions on Weiss’s bumper to the 

clothing of the victim or any other relevant party. 

¶38 Further, the State could have called Hewitt as a rebuttal witness to elicit her

testimony. “‘Rebuttal evidence offered by the State is admissible if it has a tendency to 

contradict or disprove evidence of the defense.’” State v. Gardner, 2003 MT 338, ¶ 36, 

318 Mont. 436, 80 P.3d 1262 (citation omitted). “‘Rebuttal testimony is proper only if it 

tends to counteract a new matter offered by the adverse party.’” Gardner, ¶ 36 (citation 

omitted). During her cross-examination of Ammen, Garding asked whether the State 

Crime Lab had the capability of analyzing fabric impressions, which Ammen answered 

affirmatively. The State then called Hewitt to address this newly raised issue.

¶39 Garding cites § 46-15-322(6), MCA, for the proposition that “the State is required 

to disclose the names of rebuttal witnesses ‘no later than five days before trial or at a later 

time as the court may for good cause permit.’” However, this statute applies to witnesses 

called by the State to rebut affirmative defenses that a defendant has raised and notified 

the State of pursuant to § 46-15-323(3), (4), MCA. The State did not call Hewitt to rebut 

any of these defenses. As we have held, “[d]etermining the admissibility of rebuttal 
18

testimony is within the sound discretion of the district court . . . .” State v. Jackson, 2009 

MT 427, ¶ 68, 354 Mont. 63, 221 P.3d 1213. 

¶40 The District Court’s decision to allow Hewitt to testify did not constitute 

reversible error. Hewitt’s statements were very brief and Garding fully cross-examined 

her. Even if we were to determine that the District Court abused its discretion, such error 

would be harmless. See Stewart, ¶ 45. The fact that the State called Hewitt during its 

case in chief, rather than as a rebuttal witness later, did not prejudice Garding in any way, 

nor did it contribute to her conviction. 

¶41 Affirmed.
