Washington — The Supreme Court on Friday upheld a new law that would lead to a ban of the social media platform TikTok, clearing the way for the widely popular app to shutter in the U.S. as soon as Sunday.

The Supreme Court’s remarkably speedy decision Friday to allow a controversial ban on TikTok to take hold will have a dramatic impact on the tens of millions of Americans who visit the app every day and broad political implications for President-elect Donald Trump.

Although President-elect Donald Trump could choose to not enforce the law, it’s unclear whether third-party internet service providers will support the app.

The app had more than 170 million monthly users in the U.S. The black-out is the result of a law forcing the service offline unless it sheds its ties to ByteDance, its China-based parent company.

In an unsigned opinion, the Court sided with the national security concerns about TikTok rather than the First Amendment rights. There were no noted dissents.

The high court doesn't announce which opinions it is releasing. But the justices are up against a Sunday deadline for TikTok to cut ties with China.

The Supreme Court on Friday unanimously upheld a law requiring TikTok ... shutting down the app entirely if the ban goes into effect Sunday. Apple and Google did not immediately respond to questions about whether they plan to keep TikTok on their app ...

The Supreme Court upholds the U.S. bill that would essentially ban TikTok. As AFROTECH™ previously reported, the Court demonstrated that it was “likely” to rule in favor of banning the application owned by ByteDance.

The U.S. Supreme Court upheld on Friday a law banning TikTok in the United States on national security grounds if its Chinese parent company ByteDance does not sell the short-video app by Sunday, as the justices in a 9-0 decision declined to rescue a platform used by about half of all Americans.

The Supreme Court rejected TikTok's appeal to halt a law banning the app in the U.S. unless Chinese parent ByteDance sells its stake by Jan. 19.

Donald Trump had asked the Supreme Court to delay TikTok’s ban-or-sale law to give him an opportunity to act once he returns to the White House.

WASHINGTON — The Supreme Court on Friday unanimously upheld the federal law banning TikTok beginning Sunday unless it’s sold by its China-based parent company, holding that the risk to national security posed by its ties to China overcomes concerns about limiting speech by the app or its 170 million users in the United States.
