TikTok detailed on Thursday why it thinks the new federal law that could lead to a ban of the popular video app in January is unconstitutional, calling the legislation an “extraordinary restriction on speech.”

The company said that Congress did not consider the law — which would force TikTok’s Chinese owner to sell the popular social media app or face a ban in the United States — with nearly enough scrutiny and care.

TikTok made the arguments in a filing to the U.S. Court of Appeals for the District of Columbia Circuit, where the company sued to block the law in May.

“This law is a radical departure from this country’s tradition of championing an open Internet, and sets a dangerous precedent allowing the political branches to target a disfavored speech platform and force it to sell or be shut down,” the company said Thursday’s filing.

The company also said that it wasn’t clear that Congress had considered the company’s efforts to reach a compromise with the Biden administration. To support its argument, the company released a trove of documents about numerous confidential meetings and other interactions with top federal officials, nearly all of which have been shrouded in secrecy.

The new documents include a 90-page proposal from TikTok about how it planned to address concerns among American national security officials about the app, including worries that the Chinese government could use it to spread propaganda or collect sensitive user data.
