The Montana Supreme Court ruled on November 10, 2026, to uphold the dismissal of Shandell Warren's complaint against Sandra Dewey. The court found that Warren failed to provide sufficient arguments to challenge the lower court's decision. This ruling affects Warren, who sought damages related to a prior incident involving Dewey.

The case originated from a dispute between Warren and Dewey that occurred on February 28, 2022, in downtown Helena. Warren was walking her service dog when Dewey, who was working for the Helena parking commission, allegedly kicked the dog. Following this incident, Dewey obtained an order of protection against Warren, which later expired on October 22, 2022. Warren was also charged with disorderly conduct related to the incident, but those charges were ultimately dismissed.

Warren initially filed her complaint against Dewey on August 29, 2023, in the Lewis and Clark County Justice Court. However, the court dismissed her complaint without prejudice due to a lack of subject-matter jurisdiction. Warren refiled her complaint in the District Court on September 27, 2023, claiming that Dewey made false accusations against her and that these accusations led to legal expenses and emotional distress. She sought $4,230 in damages. Dewey denied the allegations and filed a motion to dismiss, arguing that Warren's claims did not establish a legal basis for relief.

On January 13, 2025, the District Court dismissed Warren's complaint with prejudice, stating that she failed to cite any legal theory or case law to support her claims. The court concluded that her allegations did not state a cognizable claim. Warren attempted to appeal this dismissal but faced procedural issues, including a lack of a ruling on her initial notice of appeal.

In its ruling, the Montana Supreme Court, led by Justice Katherine M. Bidegaray, affirmed the District Court's dismissal. The court stated, "Because Warren has not developed an appellate argument demonstrating error in the District Court’s determination that her complaint failed to state a claim, we affirm the dismissal." The court emphasized that an appellant must present a clear argument explaining the claimed error, and Warren did not meet this requirement.

The court also noted that while it may provide some leeway for self-represented litigants, all parties must adhere to procedural rules. Warren's allegations of judicial bias and requests for a hearing were also dismissed due to a lack of developed legal argumentation. The court did not address whether Warren's complaint could have stated a claim for malicious prosecution.

This ruling has significant implications for Warren as she sought damages for her claims against Dewey. The decision reinforces the importance of presenting a well-structured argument when appealing a court's decision. It also highlights the challenges faced by self-represented litigants in navigating the legal system.

Looking forward, Warren may consider pursuing further legal options, but the court's ruling limits her immediate avenues for appeal. The court's decision does not set new legal precedent, as it is classified as a memorandum opinion, which cannot be cited in future cases. The court's ruling is final unless further challenged in a different context or through a different legal avenue.
