Recently, several public threats by United States Government officials to ban TikTok triggered national discourse on the impact of technology on national security.[1] In April 2024, President Biden signed The Protecting Americans From Foreign Adversary Controlled Applications Act (“Act”) which bans Americans from downloading TikTok.[2] The Act requires ByteDance, the Chinese tech-giant which owns most of the social media application (“app”) TikTok, to sell the app within 12 months or face its removal from U.S. app stores.[3]
In January 2025, TikTok’s lawyers argued that the Act violates the First Amendment before the Supreme Court of the United States.[4] Although the Act does impact speech and a strong argument can be made for a First Amendment violation, the Act itself does give light to another Constitutional question: whether the Act is a bill of attainder.[5] However, this standard is very hard to surpass and was not successful for TikTok in the lower court.[6]
The Act makes it illegal for platforms, like the Apple App Store, to “distribute, maintain, or update” a “foreign adversary controlled application” within the United States.[7] To determine whether an app qualifies as a Foreign Adversary Controlled Application, the Act focuses on whether it is run, either directly or indirectly, by one of two groups.[8] The first group, described in Subparagraph (g)(3)(A), specifically names ByteDance and TikTok.[9] The second group, outlined in Subparagraph 2(g)(3)(B) includes any “covered company” which is a company controlled by a foreign adversary deemed by the President to pose a significant national security threat.[10] To fall under (g)(3)(B), specific explanations and qualifications give a warning to foreign controlled apps, unlike the explicit inclusion of TikTok under (g)(3)(A).[11]
The impacts of this Act rest largely on entities in the United States to stop providing support for the Foreign Adversary Controlled Application, rather than on TikTok itself.[12] It does, however, include an exemption “for qualified divestitures,”[13] allowing foreign adversary owners to sell their app and relinquish control in exchange for the app remaining available to Americans.[14]
On January 10th, 2025, the Supreme Court heard oral arguments on whether the Act violates the First Amendment.[15] The Court granted certiorari to review this question,[16] though, this is a “somewhat novel” set of facts to be arguing a claim for a violation of the First Amendment.[17] The D.C. Circuit Court, which previously heard this case, upheld the Act under strict scrutiny, finding that the speech restrictions imposed are narrowly tailored to address national security concerns.[18] The Supreme Court upheld the Act on January 17th, 2025, stating that their “analysis must be understood to be narrowly focused in light of these circumstances.”[19]
Despite this recent development, an argument that seems more obvious based on the language of the Act is that the Act is a bill of attainder and therefore unconstitutional.[20] Originally the bill of attainder clause in the Constitution aimed to prohibit federal and state laws from punishing a specific individual.[21] While the clause was initially interpreted to protect individuals, some courts, including the D.C. Circuit Court, extended it to corporations.[22] TikTok raised this argument in the Circuit Court, arguing that the specific reference to ByteDance and TikTok in the Act makes it a bill of attainder.[23] By naming these companies directly, the Act bypasses TikTok’s owners from the additional procedural safeguards outlined in Subsection (g)(3)(B).[24]
To determine whether a law is a bill of attainder, a court will consider whether it applies with specificity and imposes punishment.[25] The Circuit Court concluded that the Act applies with specificity since it names ByteDance and TikTok,[26] but the Act does not impose punishment.[27] Despite the Act’s language giving light to a bill of attainder claim, the D.C. Circuit quickly shut down this argument,[28] and TikTok was not given the chance to argue it in front of the Supreme Court.[29] Although the language of the Act may allude to the fact that the Act is a bill of attainder, the punishment aspect falls short.[30]
Though the Act undeniably impacts speech, the “somewhat novel” situation gave the Supreme Court an opportunity to create a First Amendment doctrine for new technology, especially social media.[31] Despite this, the Court did not, stating that when applying legal rules to new issues raised by technology, they “should not care to ‘embarrass the future.’”[32]
Yet, it still feels inherently wrong to grant other app owners, besides TikTok’s, a more proper procedure under Subsection (g)(3)(B).[33] The D.C. Circuit’s ruling leaves us questioning whether the law treats TikTok unfairly.[34] National Security concerns are important, and Congress must pass legislation that reflect these interests. However, if TikTok would still be considered a Foreign Adversary Controlled Application under Subsection (g)(3)(B) it seems unnecessary to single out TikTok and bypass procedural fairness and evaluation.[35]
