__________________________________________ Clerk Justice Laurie McKinnon delivered the Opinion of the Court.

¶1 Appellant Katie Irene Garding (Garding) appeals from the December 16, 2024

Order of the Fourth Judicial District Court, Missoula County, reinstating her convictions

for Vehicular Homicide While Under the Influence, Failure to Stop Immediately at an

Accident Scene Involving an Injured Person, and Driving Without a Valid Driver’s

License. The District Court ordered the Montana Department of Corrections to resume

custody over her. We affirm in part and reverse in part.

¶2 We restate the dispositive issue on appeal:

Whether the District Court erred in reinstating Garding’s convictions following Garding’s outstanding motion for judicial substitution.

FACTUAL AND PROCEDURAL BACKGROUND

¶3 The facts underlying Garding’s charges have been set forth on numerous occasions.

See State v. Garding (Garding I), 2013 MT 355, 373 Mont. 16, 315 P.3d 912; Garding v.

State (Garding II), 2020 MT 163, 400 Mont. 296, 466 P.3d 501; Garding v. Mont. Dep’t

of Corr. (Garding III), No. CV 20-105-M-DLC, 2023 WL 3086883 (D. Mont. March 27,

2023); and Garding v. Mont. Dep’t of Corr. (Garding IV), 105 F.4th 1247 (9th Cir. 2024),

cert. denied, ___ U.S. ___, 145 S. Ct. 1951 (2025). We will not recite them again as they

have no bearing on the issue we need to resolve. On June 10, 2011, a jury convicted

Garding of all charges and she received a total sentence of forty years to prison. Garding I,

¶ 17.

¶4 In 2013, Garding filed an appeal to this Court challenging her conviction on three

grounds. Garding I, ¶ 17. Garding argued that the district court erred by limiting the

2 Defendant’s cross-examination of the State’s informant thus violating her right of

confrontation; permitting an undisclosed expert witness to testify for the State; and

preventing her expert from testifying regarding matters disclosed within the expert’s report.

Garding I, ¶¶ 20, 26, 35. We affirmed the district court. Garding I, ¶ 41. In our holding

we concluded Garding had been afforded the opportunity to cross-examine the State’s

informant regarding any potential bias and was provided with ample time to interview the

State’s undisclosed expert witness. Further, we held that the district court’s limitation on

Garding’s expert witness testimony was harmless error. Garding I, ¶ 40.

¶5 In 2015, Garding filed a petition for postconviction relief in the district court

alleging she received ineffective assistance of counsel (IAC) due to her trial counsel’s

failure to hire an accident reconstructionist; discovery violations under Brady v. Maryland,

373 U.S. 83, 83 S. Ct. 1194 (1963); and that a post-trial crash reconstruction analysis

constituted newly discovered evidence satisfying the exception to the one-year time bar for

postconviction relief petitions. Garding II, ¶ 10. The district court granted the State’s

motions for summary judgment and denied Garding’s postconviction relief claim after a

hearing. Garding II, ¶ 11. Garding appealed the denial of her postconviction relief petition

in 2020. Garding II, ¶ 11. This Court affirmed the district court. Garding II, ¶ 42. We

first held Garding’s IAC claim failed under the Strickland1 standard because the decision

to not hire an accident reconstructionist was not outside the wide range of professionally

competent assistance. Garding II, ¶ 23. Second, this Court concluded Garding’s claim

1 Strickland v. Washington, 466 U.S. 668, 104 S. Ct. 2052 (1984). 3 under Brady failed. We determined both the victim’s x-rays and photos of an unrelated

2005 motor vehicle crash were not in the prosecution’s possession. Garding II, ¶ 35.

Further, the photos of the unrelated 2005 motor vehicle crash were not material or

exculpatory and were, therefore, exempt from the requirements imposed by Brady on the

prosecution. Garding II, ¶ 35. Finally, this Court found the district court correctly rejected

Garding’s new evidence claim, as the accident reconstruction analyses offered by

Garding’s experts were merely newly analyzed evidence. Garding II, ¶ 42.

¶6 In 2023, having exhausted state remedies, Garding filed a 28 U.S.C. § 2254(d)(1)

petition for habeas corpus in federal district court challenging her convictions. Garding III,

2023 WL at *1. In Garding’s petition, she raised three claims: (1) the State violated Brady

by failing to produce x-rays of the victim’s leg taken by Dr. Dale, (2) the State violated

Brady by failing to produce the 2005 accident photographs, and (3) Garding’s counsel was

ineffective for failing to secure an accident reconstruction expert. Garding III, 2023 WL

at *4. The federal district court concluded this Court had misapplied Strickland because

the expert testimony of a crash reconstructionist would have established, within a

reasonable degree of certainty, that Garding’s vehicle could not have been the vehicle that

struck the victim. Garding III, 2023 WL at *4. However, the federal district court denied

Garding’s Brady claims. Garding III, 2023 WL at *19. Accordingly, the federal district

court granted Garding’s writ of habeas corpus and ordered that the State, within 30 days,

either (1) move to vacate the state criminal judgment and renew proceedings against

Garding in the state trial court, or (2) immediately and unconditionally release Garding

from all custody that was imposed for her prior convictions, and that Garding may not be

4 retried. Garding III, 2023 WL at *20. The State was required to file notice by April 21,

2023, with the federal district court if it intended to renew proceedings in state court.

Garding III, 2023 WL at *20.

¶7 On April 19, 2023, the State filed a motion with the state District Court to renew

proceedings and set a status hearing. Thereafter, the state District Court, “pursuant to the

Order in the United States District Court,” vacated Garding’s criminal judgment, reinstated

the 2011 Information, and renewed criminal proceedings against Garding. In response to

the renewed criminal action, Garding filed a motion to substitute the district judge.

¶8 Both the State and Garding appealed and cross-appealed, respectively, the federal

district court’s partial grant of habeas corpus relief. Garding IV, 105 F.4th at 1250. While

the proceeding was pending before the Ninth Circuit, the parties stipulated to continue the
