TikTok’s bid to overturn a law which would see it banned or sold in the US from early 2025 has been rejected.

The social media company had hoped a federal appeals court would agree with its argument that the law was unconstitutional because it represented a “staggering” impact on the free speech of its 170 million US users.

But the court upheld the law, which it said “was the culmination of extensive, bipartisan action by the Congress and by successive presidents”.

TikTok says it will now take its fight to the US Supreme Court, the country’s highest legal authority.

The US wants TikTok sold or banned because of what it says are its owners links to the Chinese state – links TikTok and parent company Bytedance have always denied.

The court agreed the law was “carefully crafted to deal only with control by a foreign adversary, and it was part of a broader effort to counter a well-substantiated national security threat posed by the PRC (People’s Republic of China).”

TikTok released a statement saying it was not the end of its legal fight.

“The Supreme Court has an established historical record of protecting Americans’ right to free speech, and we expect they will do just that on this important constitutional issue. Unfortunately, the TikTok ban was conceived and pushed through based upon inaccurate, flawed and hypothetical information, resulting in outright censorship of the American people. The TikTok ban, unless stopped, will silence the voices of over 170 million Americans here in the US and around the world on January 19th, 2025.”

Donald Trump’s victory in the 2024 US Presidential Election may also present a lifeline for the app.

Despite unsuccessfully attempting to ban TikTok during his first term in 2020, he said in the run-up to the November elections he would not allow the ban on TikTok to take effect.

Trump will be inaugurated on 20 January – the day after the law says TikTok must be be banned or sold.

However, it remains to be seen whether he will follow through on his pre-election vow. S: BBC
