Austin, TX – The legal landscape for Montana Attorney General Austin Knudsen is becoming increasingly complex, with four significant lawsuits currently challenging his office’s actions and policies. These cases encompass a range of issues, from environmental regulations to social media restrictions and allegations of professional misconduct, illustrating the intricate balance of governance and accountability in the public sector.
Environmental Lawsuit: Held v. Montana
In August 2023, a group of youth plaintiffs initiated a lawsuit against the state of Montana, asserting that its environmental policies infringe upon their constitutional rights to a clean and healthful environment. They are calling for a declaration that specific state laws are unconstitutional and urge the state to create a comprehensive plan to reduce greenhouse gas emissions. However, this case faced a setback in October 2025 when the U.S. District Court for the District of Montana dismissed the case, citing that the plaintiffs lacked standing. The plaintiffs have expressed their determination to appeal the decision.
Social Media Ban: Alario et al. v. Knudsen
In May 2023, Attorney General Austin Knudsen took a significant step by filing a lawsuit against TikTok Inc. and its parent company, ByteDance Ltd., aiming to ban the TikTok app in the state. The lawsuit claims that TikTok poses national security risks due to its alleged connections to the Chinese government. A pivotal moment occurred in November 2023 when the U.S. District Court for the District of Montana issued a preliminary injunction, temporarily blocking the enforcement of the ban until a final ruling on the merits of the case can be made.
Professional Conduct Allegations: Monforton v. Knudsen
In a separate legal challenge, a complaint was lodged against Attorney General Knudsen in September 2023, alleging 41 violations of the Montana Rules of Professional Conduct. The complaints were tied to Knudsen’s actions during a legal dispute between the state Legislature and the judiciary in 2021. Following this, the Montana Supreme Court appointed a panel to evaluate the claims, and in October 2024, the Commission on Practice recommended a 90-day suspension of Knudsen’s law license. The final determination on this matter is anticipated to be made by the Montana Supreme Court.
Federal Overreach Challenge: Lighthiser v. Trump
Additionally, in May 2025, a group of youth plaintiffs filed a lawsuit against the Trump administration, targeting executive orders they argue would worsen climate change. Attorney General Knudsen intervened, labeling the lawsuit a “taxpayer-funded publicity stunt.” In October 2025, this case was dismissed by the U.S. District Court for the District of Montana on the grounds that the plaintiffs lacked standing. Like the other lawsuits, the plaintiffs have indicated their intention to appeal.
These lawsuits highlight the ongoing legal challenges faced by the Montana Attorney General’s office, addressing critical issues surrounding environmental regulations, social media restrictions, and professional conduct. The outcomes of these cases may have significant implications not only for the office of Attorney General Knudsen but also for the broader legal and political landscape in Montana.
