TikTok argued in court on Monday that a US law – which would see it banned unless it is sold by ByteDance – would have a “staggering” impact on the free speech of its US users.
The law was prompted by concerns that US users’ data is vulnerable to exploitation by China’s government.
TikTok and ByteDance have repeatedly denied links to the Chinese authorities.
The companies sued to block the legislation in early May, calling it unconstitutional and an effective ban on the speech of its 170 million US users.
A panel of three judges heard its arguments at an appeals court in Washington DC on Monday.
“This law imposes extraordinary speech prohibition based on indeterminate future risks,” TikTok and ByteDance’s lawyer Andrew Pincus told the court.
Concerns around China came up early, with Mr Pincus stating that the firm “is not owned” by the country.
“The owner of TikTok is ByteDance Limited, a Cayman Islands holding company,” he said.
But Judge Sri Srinivasan responded that the firm was “subject to Chinese control”.
Mr Pincus said the US government does not allege any malfeasance has taken place – and the firm was being punished over the suggestion that there might be issues in the future.
But he was challenged on his argument that the law would be an unprecedented ban.
Judge Ginsberg argued the law is “an absolute bar on the current arrangement of control” of the company, not the company itself.
He also said it targeted a group of companies controlled by a so-called foreign adversary, rather than TikTok alone.
Constitutional right
Jeffrey Fisher, representing creators concerned by the law, said it would impede their constitutional right to work with the editor and publisher of their choice – such as TikTok under its current ownership.
Lawyers from the Department of Justice (DoJ) are also laying out their case.
In addition to data concerns, officials and lawmakers have expressed alarm at the prospect of TikTok being used by the Chinese government to spread propaganda to Americans.
However, advocates of America’s powerful free speech rights, enshrined in the First Amendment of the US Constitution, have said upholding the divest-or-ban law would be a gift to authoritarian regimes everywhere.
“We shouldn’t be surprised if repressive governments the world over cite this precedent to justify new restrictions on their own citizens’ right to access information, ideas, and media from abroad,” said Xiangnong Wang, a staff attorney at Columbia University’s Knight First Amendment Institute.
But according to James Lewis, of the Center for Strategic and International Studies in Washington, the law was drafted to withstand judicial scrutiny.
“The substance of the case against TikTok is very strong,” Mr Lewis said.
“The key point is whether the court accepts that requiring divestiture does not regulate speech.”
Mr Lewis added that the courts usually defer to the president on national security matters.
Regardless of how the appeals court rules, most experts agree the case could drag on for months, if not longer.
Mike Proulx, vice president and research director at analysis firm Forrester, added the “high stakes” case would likely progress to the US’ highest court, the Supreme Court.
