Background

In June 2024, L.S., a 76-year-old woman experiencing hallucinations, delusional thinking, and an inability to care for her basic needs, was brought by her husband to a hospital emergency room. After evaluation by a certified professional, she was placed at Montana State Hospital. The Lewis and Clark County Attorney filed a petition for involuntary commitment, and the First Judicial District Court ultimately ordered L.S. committed for a period not to exceed 90 days for care, treatment, and evaluation of her mental health needs.

L.S. appeared by video from the State Hospital at the June 10, 2024 advisement hearing and the June 13, 2024 evidentiary hearing. Throughout the proceedings, her ability to hear was intermittently in question. Witnesses were asked at points to speak louder or closer to the microphone. L.S. herself testified that she had been provided hearing aids for the morning of the evidentiary hearing. After the District Court announced its oral findings, L.S.’s counsel noted that L.S. stated she could not hear, but no formal objection or request for accommodation was made at any point during the proceedings.

L.S. appealed, arguing for the first time on appeal that the District Court violated her due process rights by failing to ensure she could hear and meaningfully participate in the commitment proceeding. Because no objection was raised below, she sought plain error review.

The Court’s Holding

The Montana Supreme Court affirmed the commitment order, declining to grant plain error review. The court applied the established two-part test for plain error review, which requires the appellant to show both that the alleged error implicates a fundamental right and that failure to review would result in a manifest miscarriage of justice, leave unsettled the fundamental fairness of the proceedings, or compromise the integrity of the judicial process.

The court found that L.S. did not satisfy this standard. Examining the record, the court concluded that L.S. was in fact able to hear and participate in the proceeding: adjustments were made in response to her complaints, the hearing continued at length without further interruption, she communicated with her counsel, and she testified on her own behalf. The court also noted that a written order setting forth the District Court’s findings was provided to L.S. shortly after the hearing. The absence of any objection by L.S.’s counsel—who declared readiness to proceed at the start of the evidentiary hearing without raising hearing concerns—further confirmed the court’s assessment that meaningful participation occurred.

Key Takeaways

  • Issues not raised at the trial level in involuntary civil commitment proceedings are not preserved for appeal and are subject to the demanding plain error standard, which requires a showing of manifest injustice or fundamental unfairness.
  • Hearing difficulties at a commitment proceeding do not automatically constitute a due process violation; courts will examine the full record to assess whether the respondent was actually able to meaningfully participate after accommodations were made.
  • Counsel’s failure to object to a participant’s inability to hear, and affirmative representation of readiness to proceed, weighs heavily against a later due process challenge on those grounds.
  • This decision is noncitable under Montana Supreme Court Internal Operating Rules and does not establish or modify precedent.

Why It Matters

This case highlights the intersection of disability accommodation and due process in involuntary civil commitment proceedings. Montana law, at § 49-4-503(3)(a), MCA, requires courts to appoint a qualified interpreter for deaf persons in mental health commitment proceedings, and L.S. argued this statute applied to her situation. The court did not directly resolve the scope of that statutory obligation, instead disposing of the appeal on plain error grounds—underscoring the critical importance of raising and preserving accommodation issues during the proceeding itself.

For practitioners, the case is a pointed reminder that failing to make a timely, formal objection to a client’s inability to participate meaningfully—even in the heightened-stakes context of involuntary commitment—can foreclose appellate relief. Attorneys representing hearing-impaired individuals in commitment proceedings should proactively request interpreter services or other accommodations before or at the outset of the hearing, and lodge a clear record objection if those needs are not met.
