Montana's TikTok Ban Goes Before the Ninth

Circuit



Updated January 17, 2025

On November  30, 2023, a federal district court issued a preliminary injunction barring enforcement of a
law banning TikTok's Montana operations. Without the district court's preliminary injunction, the
Montana  law would have become effective January 1, 2024. Montana appealed the district court's order
to the U.S. Court of Appeals for the Ninth Circuit (Ninth Circuit). As referenced in a previous Legal
Sidebar, a number of states enacted some type of restriction of TikTok platform usage, but Montana's law
(SB 419) represents the first attempted ban ofthis breadth among U.S. states per news reporting. Several
months after the district court preliminarily enjoined SB 419, Congress passed the Protecting Americans
from Foreign Adversary Controlled Applications Act (P.L. 118-50) (PAFACAA), the provisions of which
are discussed in another Legal Sidebar, as are legal actions challenging that law. The Ninth Circuit
ordered a stay of the appellate proceedings regarding Montana's law until 30 days following the outcome
of the PAFACAA  litigation. On December 6, 2024, a three-judge panel of the U.S. Court of Appeals for
the D.C. Circuit (D.C. Circuit) rejected all of TikTok's constitutional objections to the PAFACAA and
denied TikTok's petitions. This ruling led TikTok to petition the U.S. Supreme Court for review. On
January 17, 2025, in aper curiam opinion, the Supreme Court upheld the D.C. Circuit's ruling. This
action paves the way for the Ninth Circuit to conclude its adjudication of the Montana law giving rise to
some similar questions, but with different implications for state powers and federalism. Because the
Supreme  Court's adjudication upholds the federal ban of TikTok, many issues before the Ninth Circuit are
likely moot. This Sidebar (1) briefly describes the preliminary injunction of SB 419, (2) discusses
selected legal issues before the Ninth Circuit, and (3) highlights some topics that these legal challenges
might raise for Congress.


District Court's Preliminary Injunction of SB 419

Montana's TikTok legislation prompted substantial public commentary. According to the law's preamble,
SB 419 supports the health and safety of Montanans by preventing TikTok's operation in the state and
also expresses concerns about TikTok's parent company being subject to control by the People's Republic
of China (PRC), gathering of user information, and dangerous content. (The broader policy issues
related to the legislation are beyond the scope of this Sidebar.)
