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

¶1 Darrin William Matt (“Matt”) appeals the April 5, 2023 Judgment entered in the

Twentieth Judicial District Court, Lake County, sentencing him to 24 years in the Montana

State Prison for felony Assault on a Peace Officer in violation of § 45-5-210, MCA. We

affirm in part, and vacate and remand in part for resentencing.

¶2 We restate the dispositive issues on appeal as follows:1

Issue One: Whether the District Court illegally sentenced Matt for exercising his constitutional rights.

Issue Two: Whether this Court should exercise plain error review to consider Matt’s claim that alleged police misconduct violated his right to due process.

FACTUAL AND PROCEDURAL BACKGROUND

¶3 At 7:30 a.m. on September 8, 2022, Matt was incarcerated in the detention facility

of the Confederated Salish and Kootenai Tribes (“CSKT” or “Tribes”). Matt experiences

severe mental health disorders for which he is prescribed several medications. Zane Bundy

(“Bundy”), a CSKT detention officer, was due to administer Matt’s prescribed medication

at 9:00 a.m. Alone in a cell and without these medications, Matt became “distraught” and

“upset.” Bundy could hear Matt “yelling” for his medication.

¶4 Previously, detention center staff had provided Matt with cleaning supplies for his

cell. When Bundy approached Matt to retrieve those shortly before 9:00 a.m., Matt threw

water in his face. As revealed by surveillance footage played for the jury at trial, Bundy

1 Matt also asks this Court to strike the imposition of fees and fines. Because we vacate his sentence and remand for resentencing, we need not address whether the District Court properly assessed financial obligations in the instant case. 2 then put Matt into a hold on the floor of his cell. The two men scuffled on the floor until

three additional detention officers arrived to assist Bundy. One detention officer tased Matt

twice as two more detention officers arrived. At this point, Matt became docile and officers

handcuffed him before transporting him to a solitary concrete block cell in the facility.

Once in this cell and still without his medications, Matt began hurting himself by hitting

his head against the concrete wall twice.

¶5 CSKT police captain Louis Fiddler would testify the jail relied on a “restraint chair”

as the only intervention option when an inmate is self-harming. Officers entered Matt’s

temporary cell with the chair and asked him to sit; Matt initially complied and officers were

able to strap his arms, shoulders, and left leg to the chair. Bundy, as part of the assembled

team fitting Matt into the restraint chair, attempted to secure Matt’s right leg. Matt then

kicked Bundy in the left cheek with his unrestrained leg. Although Bundy did not seek

medical treatment for the injury, he said his jaw hurt and eating was painful for several

weeks afterward. According to Fiddler, three officers had been injured in a similar manner

when trying to secure other inmates to the restraint chair that summer. Officers managed

to fully restrain Matt and position his chair toward the wall. Bundy placed a spit hood over

Matt’s head after he spat on an officer. Left alone in the cell, Matt spent several minutes

struggling against the restraints.

¶6 The State charged Matt with assault on a peace officer by Information and filed

notice of its intention to seek a persistent felony offender designation. Following a one-day

trial on February 6, 2023, a jury convicted Matt. At sentencing, the State recommended

incarcerating Matt for 24 years while Matt’s attorney requested a five-year sentence, noting

3 the average sentence for assault on a peace officer is four-and-a-half years. Matt spoke of

his progress with the CSKT Tribal Reentry Program to meet his substance and mental

health treatment needs as well as finding assistance securing stable housing and

employment. He additionally apologized for past disrespect.

¶7 The District Court pronounced Matt’s sentence and the reasons for the sentence:

All right, Mr. Matt, we had a jury trial in this matter, and you wasted everyone’s time. There was a video of this incident. It was very clear to everyone, including the jury, that you were guilty of assault on a peace officer. I don’t think the jury deliberated very long at all because it was—we saw it as clear as day. There was video.

So again, you wasted jurors’ time, you wasted the [c]ourt’s time, you wasted the State’s time, your attorney’s time, all the taxpayers who had to pay for all this.

In your [Presentence Investigation Report (“PSI”)], you stated what reason do you have for your involvement in this offense. You said, Officer abuse of prisoner, which there was no evidence of. Again, it was very clear that you assaulted this officer.

I realize that, like [Defense Counsel] said, punishment—or sentencing is meant to prevent, deter, and rehabilitate. The State of Montana has already spent 30 years, almost, trying to rehabilitate you and it hasn’t worked and it’s not going to work anymore.

So, you failed to take responsibility for what you did. You assaulted a peace officer. You’ve had an extremely poor history on supervision and at the Department of Corrections. You’re rated very high as a risk to reoffend, the highest that’s possible.

Again, the State of Montana and tax payers [SIC] have already expended a significant amount of money trying to rehabilitate you. So for that, having been found guilty of assault on a peace officer, sentence is as imposed as follows . . . .

The District Court then sentenced Matt to the Montana State Prison for 24 years, with no

time suspended, and assessed fees and fines. Matt now appeals.

4 STANDARD OF REVIEW

¶8 This Court reviews a criminal sentence for legality. State v. Villalobos, 2024 MT

301, ¶ 7, 419 Mont. 256, 560 P.3d 617. We exercise plenary review of constitutional

questions. City of Kalispell v. Salsgiver, 2019 MT 126, ¶ 11, 396 Mont. 57, 443 P.3d 504.

¶9 In general, this Court will not review an issue raised for the first time on appeal.

State v. Favel, 2015 MT 336, ¶ 13, 381 Mont. 472, 362 P.3d 1126; State v. Kotwicki, 2007

MT 17, ¶ 8, 335 Mont. 344, 151 P.3d 892. However, when a defendant’s fundamental

rights are invoked, we may invoke the common law plain error doctrine when failing to

review the claimed error may result in a manifest miscarriage of justice, may leave

unsettled the question of fundamental fairness of the trial or proceedings, or may

compromise the integrity of the judicial process. Favel, ¶ 13.
